专利说明:
Field of Invention [0001] The subject matter of this application generally refers to methods and apparatus, including computer program products, for predicting high intensity weathering potential. Background of the Invention [0002] Lightning includes electrical discharges within a cloud, discharges within clouds (IC), and cloud-to-ground discharges (CG). Lightning occurs when electric fields within a cloud intensify particles of opposite polarity grouped in different regions within the cloud. Lightning begins with an initial electrical break (ie, a pulse) followed by conductive channels from which a series of channel branches develop into a cloud forming a comprehensive branch channel structure. For lightning IC, the channel structure remains within the cloud. A CG discharge occurs when one or more branches extend from a cloud to the ground. [0003] An increase in lightning activity usually precedes even more severe weather phenomena such as very strong storms, tornadoes, hail, damaging gust winds and potentially deadly lightning from the cloud to the ground. Furthermore, such lightning activity often occurs in localized clusters, also called cells. Lightning cells exhibit certain characteristics (eg, lightning rate, IC/CG ratio) that are indicative of the potential for high intensity weathering. Furthermore, using detection methods and systems, data associated with lightning cells can be obtained and analyzed to determine the location and movement of specific cells across a geographic region. [0004] Accurate and efficient detection of early lightning activity, such as weaker initial IC discharges, is crucial for early prediction of high intensity weather phenomena. Integrated IC Lightning and CG Lightning Detection provides highly advanced prediction capabilities to characterize high intensity storm precursors, improving wait times and comprehensive weather management planning. Various lightning detection systems and methods have been developed, individually striving to determine the location, motion, frequency and intensity of lightning activity with better accuracy. Examples of such systems include the U.S. Precision Lightining Network (USPLN), the National Lighting Detection Network (NLDN) and the WeatherBug Total Lighting Network (WTLN). [0005] Previous weather warning systems relied on human intervention to determine the extent of high intensity weather activity and to initiate notification of remote devices configured to receive alerts (for example, through the use of a display where a person evaluates weather data and selects devices to receive alerts). To increase the speed and accuracy of weather warning systems, it is desirable to eliminate the need for manual processing of high intensity weather data and issuing warning messages. Invention Summary [0006] An important goal associated with accurate, early detection of high intensity weather activity is to timely issue automated warnings, or alerts, to entities that may be affected by high intensity weather. More accurate detection of atmospheric conditions that potentially result in high intensity weather, such as lightning rates, leads to a more comprehensive understanding of the risk of hazardous weather activity in specific geographic areas. Knowing the potential for bad weather before a serious storm hits a specific region allows for more waiting time to alert people or entities located close to risk areas, resulting in greater security for these people and entities. [0007] In an overview, the techniques described here are related to the prediction of high intensity weathering potential. The techniques advantageously provide automated high-intensity weather prediction for timely issuance of reliable warnings of high-intensity weather. The techniques use accurate detection of lightning events such as CG and IC lightning flashes to identify the boundaries of lightning cells. The techniques also consider differences in geographic location and weather conditions to produce more accurate forecasts of the course and weather of high intensity weather. The techniques also provide automatic identification of remote devices configured to receive alerts for a specific geographic area and automatic transmission of relevant alerts to remote devices. [0008] The invention, in one aspect, presents a computer-implemented method for predicting high intensity weather potential. Data associated with lightning activity is received by a computing device. A location, a speed of movement, a direction of movement, and a lightning rate of one or more lightning activity cells are determined by the computing device based on the received data. The determined lightning rate is compared by the computing device with a threshold lightning rate. One or more geographic areas at risk are determined by the computing device based on the location, speed of movement and direction of movement of one or more lightning activity cells. An alert is issued by the computing device to one or more remote devices monitoring geographic areas at risk when the lightning rate exceeds a threshold lightning rate value. [0009] The invention, in one aspect, presents a computer-implemented system to predict the potential of high intensity weather. The system includes a computing device configured to receive data associated with lightning activity. The computing device is further configured to determine a location, a speed of movement, a direction of movement, and a lightning rate of one or more lightning activity cells based on the received data. The computing device is further configured to compare the determined flash rate with a threshold flash rate. The computing device is further configured to determine one or more geographic areas at risk based on the location, speed of movement and direction of movement of one or more lightning activity cells. The computing device is further configured to issue an alert to one or more remote devices monitoring geographic areas at risk when the lightning rate exceeds a threshold lightning rate value. [0010] The invention, in another aspect, features a computer program product embodied tangibly in a computer readable storage device to predict the potential for high intensity weathering. The computer program product includes operable instructions to cause a data processing apparatus to receive the data associated with lightning activity, and determine a location, a speed of movement, a direction of movement and a lightning rate of one or more lightning activity cells based on the received data. The computer program product further includes operable instructions to cause the data processing apparatus to compare the determined lightning rate with a threshold lightning rate, and determine one or more geographical areas at risk based on location, speed of movement and in the direction of movement of the one or more lightning activity cells. The computer program product further includes operable instructions to cause the data processing apparatus to issue an alert to one or more remote devices monitoring geographical areas at risk when the lightning rate exceeds a threshold lightning rate value. [0011] The invention, in another aspect, presents a computer-implemented system to predict the potential for high intensity weather. The system includes means for receiving data associated with lightning activity. The system further includes means for determining a location, a speed of movement, a direction of movement, and a lightning rate of one or more lightning activity cells based on the received data. The system further includes means for comparing the determined flash rate with a threshold flash rate. The system further includes means for determining one or more geographical areas at risk based on the location, speed of movement and direction of movement of the one or more lightning activity cells. The system further includes means to issue an alert to one or more remote devices monitoring the geographical areas at risk when the lightning rate exceeds a threshold lightning rate value. [0012] In some embodiments, any of the above aspects may include one or more of the following features. In some modalities, one or more polygons corresponding to geographic areas at risk are generated. In some modalities, the generated polygons are placed on a map in which at least one of the geographical areas at risk is located. In some modalities, generated polygons are transmitted to one or more remote devices as part of the alert. [0013] In some embodiments, the threshold lightning rate is determined based on historical data associated with at least one of (i) the location of one or more lightning activity cells or (ii) the period of the year. In some embodiments, the lightning rate is determined based on a number of lightning events per minute associated with one or more lightning activity cells. In some modalities, lightning events include cloud-to-ground lightning, lightning within the clouds, or both. In some embodiments, lightning within the clouds includes aerial discharges, flashes within the clouds, flashes from the cloud to the ionosphere, or any combination thereof. [0014] In some embodiments, the data received includes cloud-to-ground lightning, lightning within clouds, vertical movement, condensation, moisture, or any combination thereof. In some embodiments, data associated with lightning activity is received from one or more geographically dispersed sensing devices. In some embodiments, one or more lightning activity cells are determined according to the density of lightning activity in the received data. [0015] In some modalities, the alert is issued before the storm of great intensity has reached the location of at least one of the geographical areas at risk. In some modes, a weather type is determined based on the lightning rate. In some modes, a probability of high intensity weather is determined based on the lightning rate. In some embodiments, remote devices are personal computing devices. In some embodiments, remote devices are horns, sirens, lights, or any combination thereof. In some embodiments, a change in lightning rate of one or more lightning activity cells is determined, and an alert is issued to one or more remote devices when the change in lightning rate exceeds a predetermined value. [0016] Other aspects and advantages of the invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating, by way of example only, the principles of the invention. Brief Description of Drawings [0017] The advantages of the invention described above, together with additional advantages, may be better understood by referring to the following description taken in conjunction with the accompanying drawings. The drawings are not necessarily to scale, with emphasis generally being placed on illustrating the principles of the invention. [0018] Figure 1 is a block diagram of a system to predict the potential for high intensity weather. [0019] Figure 2 is a flow diagram of a method to predict the potential for high intensity weather using the system. [0020] Figure 3 is a diagram illustrating the identification of a lightning cell via system 100 based on the lightning activity data. [0021] Figure 4 is a graph illustrating the total lightning rate of an individual lightning cell compared to a threshold lightning rate over a specific time period. [0022] Figure 5 is a diagram illustrating the identification by the system of a geographic area at risk of high intensity weather based on the lightning activity data. [0023] Figure 1 is a block diagram of a system 100 for predicting the potential for high intensity weather. System 100 includes a data collection module 102, a data analysis module 104, an alert generation module 106, a graphics processing module 108, and a data storage module 110. In some embodiments, the components (for example, 100, 102, 104, 106, 108, and 110) of system 100 reside in the same physical location or may be dispersed to different physical locations. In some embodiments, the components of system 100 are located on the same physical device (e.g., a server computing device), or are distributed across different physical devices. The components of system 100 communicate, for example, via a communication network (eg, WAN, LAN, WLAN). [0024] Figure 2 is a flow diagram of a method 200 for predicting the potential for high intensity weather using system 100. Data collection module 102 receives (202) the data associated with lightning activity. The data analysis module 104 determines (204) a location, a speed of movement, a direction of movement and a lightning rate of one or more lightning activity cells based on the data received by the data collection module 102. Data analysis module 104 compares (206) the determined flash rate to a threshold flash rate. The alert generation module 106 determines (208) one or more geographical areas at risk based on the location, the speed of movement, the direction of movement of the one or more lightning activity cells. The alert generation module 106 issues (210) an alert to one or more remote devices monitoring the geographical areas at risk when the determined lightning rate exceeds a value of the threshold lightning rate. [0025] Data collection module 102 provides an interface between external data sources (not shown) and data analysis module 104 of system 100. Data collection module 102 receives the data associated with lightning activity to from various external data collection and/or monitoring systems. For example, data collection module 102 receives data from a lightning detection system comprising a plurality of geographically dispersed weather sensors (e.g., the WeatherBug Total Lightning Network (WTLN)). In this example, the data collected by the weather sensors includes analog radio frequency (RF) energy (eg, pulses or flashes) at different frequencies as emitted by a lightning strike. Additional detail regarding lightning activity detection and lightning activity data collection is found in US Patent Application Serial No. 12/542,404 entitled "Method and Apparatus for Detecting Lightning Activity", which is incorporated herein fully. Other sources of lightning activity information include, but are not limited to, government agencies and private third-party companies. The data collection module 102 communicates with various systems and external data sources through standard communication networks and methods. [0026] The data collection module 102 also consolidates the lightning activity data received from a plurality of external data sources into a format conducive to processing by the data analysis module 104. For example, each data source to which the data collection module 102 is connected may transmit the data using a different syntax and/or different data structure. The data collection module 102 analyzes the incoming data according to an understanding of the data source and re-formats the data so that it conforms to an acceptable syntax or structure for the data analysis module 104. In some embodiments, external data sources transmit the lightning activity data in a standard format (eg XML) to reduce the processing required by the data collection module 102. The data collection module 102 communicates with the data collection module 102 data storage 110 for saving and retrieving the data received from external sources in preparation for transmitting the data to the data analysis module 104. When the data has been received, the data collection module 102 transmits the data to the data analysis module 104. In some embodiments, data collection module 102 transmits a notification to data analysis module 104 that data has been stored in the data analysis module. data storage 110 and are ready for processing by data analysis module 104. The notification includes a reference indicator (e.g., a database address) of the data storage location within data storage module 110. [0027] The data analysis module 104 processes the lightning activity data received by the data collection module 102 and/or stored in the data storage module 110 to determine the existence of high intensity weather hazard for one or more geographic regions. [0028] The data analysis module 104 determines the risk of high intensity weather for one or more geographic regions by monitoring the location, speed of movement, direction of movement and lightning rate of one or more lightning activity cells with based on the data received by system 100. A lightning cell is a cluster of flashes with a boundary like a polygon determined by the flash density value for a given period of time. Data analysis module 104 groups the flash data collected into lightning cells, and data analysis module 104 correlates the cell polygons over a period of time to determine the direction of movement (i.e., path) of the cells. . In addition, the data analysis module 104 counts the number of flashes in a specific lightning cell to determine a lightning flash rate (eg, flashes per minute). The data analysis module 104 further calculates the movement speed and location of the lightning cells. [0029] Figure 3 is a diagram illustrating the identification of a lightning cell 302 via system 100 based on the lightning activity data. The data analysis module 104 receives the lightning flash data from the data collection module 102 and positions each lightning flash (e.g., lightning flashes 304) according to its geographic location. Data analysis module 104 then analyzes the relative position of the lightning flashes to determine the potential boundaries or contours of specific lightning cells (eg, cell 302). [0030] In some embodiments, the data analysis module 104 performs a series of grid processes to determine the location and contours of a lightning cell 302. The data analysis module 104 uses the collected lightning flash data for a specific period of time (eg one minute) and puts the lightning flashes (eg 304 flashes) on a map. Data analysis module 104 then overlays a thick grid on the map to quickly locate areas of interest for further analysis. The data analysis module 104 identifies the grid sectors that contain a high percentage or density of lightning flashes and overlays the fine grid on the identified sectors. Data analysis module 104 employs density functions in the fine grid sectors to locate the closed contours associated with lightning cell 302. Data analysis module 104 generates a convex polygon (eg, convex polygon 306) from of each of the closed contours. [0031] The data analysis module 104 repeats this gridded process at the end of a specified period of time (eg, one minute) to monitor the changes in motion, direction, and lightning flash rate of the lightning cell 302. In most cases, the polymer 306 generated by the data analysis module 104 for a specific lightning cell at each time slot is similar to the polygon previously generated for that cell, so the data analysis module 104 correlates accordingly. efficiently and quickly the two polygons. However, in the case of a sharp increase in the lightning flash rate, lightning cell fusion or lightning cell division means, the correlation of subsequent polygons for a specific cell is not obvious. The data analysis module 104 links the individual lightning cell polygons based on the dynamically changing data to produce a path 308 of the moving lightning cell. For example, when a lightning cell is reassembled after fading, based on the cell trajectory and the time-distance of two polygons, the data analysis module 104 maintains a continuous cell trajectory 308. [0032] The data analysis module 104 also compares the lightning flash rate calculated from the received lightning activity data with a lightning threshold rate. Data analysis module 104 also monitors rate changes associated with the flash flash rate of the identified flash cells. By monitoring flash rates and rate changes, high intensity storm cells (and cells that will potentially become high intensity) are identified and monitored. The lightning threshold rate used by data analysis module 104 is relevant to the probability that the monitored lightning cell is associated with high intensity weather and can be used by system 100 to determine when to issue an alert. For example, if the lightning rate exceeds the threshold rate, the possibility that the lightning cell is associated with high intensity weather is sufficient to authorize an alert to be issued. [0033] Figure 4 is a graph 400 illustrating the total lightning rate 402 of an individual lightning cell (e.g. cell 302 of Figure 3) compared to a lightning threshold rate 404 over a specific time period . Data analysis module 104 determines the total lightning rate 402 of a lightning cell by analyzing the number of lightning events (eg, flashes) in a specific time interval (eg, one minute). In some modalities, lightning events include both CG lightning and IC lightning. In some embodiments, data analysis method 104 evaluates the collected lightning data to identify various types of IC lightning, including aerial discharges, in-cloud flashes, and/or cloud-to-ionosphere flashes. [0034] Through the action of continuously calculating the total lightning rate of a specific lightning cell at regular time intervals, the data analysis module 104 detects the changes in the total lightning rate between the time intervals. Based on this approach, the data analysis module 104 determines whether changes in lightning rate have occurred that may be indicative of high intensity weather in general or a specific type of high intensity weather (eg precipitation, wind events ). For example, the total lightning rate 402 in Figure 4 begins to increase sharply starting at time = t(0) and peaking at time = t(p), with the high intensity weather associated with the lightning cell occurring in the time = t(s). The data analysis module 104 determines whether the total lightning rate 402 meets the threshold lightning rate 304 at time = t(i) and transmits information to the alert generation module 106. In addition, the data analysis module 104 compares rate changes between time = t(0), time = t(p) and time = t(s) with a database of historical lightning rate activity to identify similarities or patterns in rate change of lightning. As an example, the specific rate changes illustrated in Figure 4 can occur multiple times during the duration of a lightning cell, and the high intensity weather resulting in time = t(s) can be the beginning of an intense hailstorm . As a result, the data analysis module 104 instructs the alert generation module 106 to provide a more detailed alert message in that additional information. [0035] The data analysis module 104 also uses the historical data to establish a threshold rate for a specific lightning cell. For example, the data analysis module 104 determines the threshold flash rate using a best-fit analysis method based on analysis of actual weather data. In some modalities, historical data is associated with a specific time of year and/or a specific geographic region. Based on a correlation between the historical period of the year and the period of the year during which the current lightning cell is being monitored, the data analysis module 104 adjusts the threshold rate to account for similarities or differences between the two data points. For example, if a lightning cell is being monitored during a period of the year that has traditionally had low occurrence of high intensity weather, the data analysis module 104 shifts the threshold rate up to require a total lightning rate higher before an alert is issued by system 100. Conversely, if a lightning cell is being monitored during a period of the year that is prone to increased high intensity weather activity, data analysis module 104 moves the threshold rate down to require a lower total lightning rate before issuing an alert. [0036] When the data analysis module 104 determines that the total lightning rate of the currently monitored lightning cell (for example, cell 302 of Figure 3) has exceeded the threshold lightning rate (i.e., is associated with a potential sufficient for high intensity weather), the data analysis module 104 transmits the data to the alert generation module 106. The alert generation module 106 uses the analyzed characteristics of the lightning cell to automatically determine the geographic areas that can be impacted by the lightning cell as it moves and changes in size and/or intensity. [0037] Figure 5 is a diagram 500 illustrating the identification by system 100 of a geographical area at risk 502 of high intensity weather based on the lightning activity data. To issue an alert that reaches people and/or entities that may be directly affected by the high intensity weather, or that may have an interest in the affected area, the alert generation module 106 determines one or more geographical areas at risk 502 based on the location, speed of movement and direction of movement of the lightning cell 302. In some embodiments, the alert generating module 106 determines a warning area that corresponds to the current location and expected trajectory of the cell over a period of time. to come. For example, the alert generation module 106 generates a polygon 502 that covers the range of distances and directions that a lightning cell could travel in a specific period of time (eg 45 minutes) by evaluating the speed of movement and the cell movement direction shown at the time the data analysis module 104 determines that the total flash rate of cell 302 has exceeded the threshold flash rate. [0038] After receiving notification from the data analysis module 104 and determining one or more areas at risk, the alert generation module 106 automatically identifies a set of one or more remote devices that are monitoring the areas at risk and automatically broadcasts an alert to remote devices. Remote devices can include computer-based devices such as mobile phones and global positioning system (GPS) hardware. Remote devices can also include other types of warning systems, such as lights, sirens, and horns that are configured to connect to a communication network. In some embodiments, data storage device 110 includes information relating to the identification of remote devices (e.g., IP address, telephone number, email address), and alert generation module 108 uses the identification information to prepare an alert for each remote device. Data storage device 110 also includes information mapping the identification of a remote device to a specific geographic area or areas that the remote device is monitoring (e.g., zip code, county name, street address). Alert generation module 106 utilizes any standard communication protocol or technique, such as packet-based delivery (eg text messaging, XML, email), circuit-based delivery (eg radio calling, phone exchange). voice messages), and the like. For example, a user can subscribe to receive alerts for a specific postal code on their mobile phone. System 100 stores the user's telephone number in data storage module 110. When alert generation module 106 identifies a geographic location that is at risk of high intensity weather and all or part of the identified location is comprised within the code user-presented, the alert generation module 108 issues an alert (e.g., a text message, a voice message) addressed to the telephone number of the user's mobile phone. In this modality, the user's mobile phone need not be located in the same geographic area as identified by the alert generation module 106 as “at risk”. [0039] In some modalities, the alert is additionally optimized through the inclusion of a graphical representation of the geographic area that is under threat of high intensity weather. The graphical representation provides an additional piece of information that can be easily recognized by the recipient of the alert. For example, the alert generation module 106 overlays a polygon 502 outlining the geographical area at risk associated with a specific lightning cell 302 on a map. Alert generation module 106 uses a graphical processing module 108 to generate a visual representation of the polygon 502 representing the area at risk as placed on the map. In some embodiments, the graphics processing module 108 is a separate graphics processing unit (GPU) (e.g., a graphics card) or a software module configured to produce graphic drawings and drawings based on the lightning activity data. [0040] The techniques described above can be implemented in digital and/or analog electronic circuits, or in hardware, firmware, computer software or combinations thereof. The implementation can be as a computer program product, that is, a computer program tangibly embedded in a machine-readable storage device, for execution by, or for controlling the operation of a data processing apparatus, by example, a programmable processor, a computer, and/or multiple computers.
