Abstract

The present invention is directed to system and method of processing meteorological data. The system receives meteorological data corresponding to a geographic region for a storm event. A hail data indicator pair comprising a first hail data indicator and a second hail data indicator is selected, with hail data indicators being meteorological data which directly or indirectly indicates hail activity.

Claims

1. A method of processing weather data for display comprising:

providing a processor and memory configured to perform the following steps

receiving a meteorological data corresponding to a geographic region from at least one meteorological data source for a storm event;

processing a hail data indicator pair comprising a first hail data indicator and a second hail data indicator, said hail data indicators being meteorological data which directly or indirectly indicates hail activity;

a storm event distribution generated using said hail data indicator pair comprising the steps of;

configuring ranges for each of said hail data indicators, tabulating the number of occurrences of data points from the storm event data within the intersecting ranges of said first hail data indicator and said second hail data indicator, and calculating the proportion of occurrences within said intersecting ranges;

a hail intensity number display matrix is calculated using said storm event distribution comprising the steps of;

for each of the second hail data indicator ranges, generating a summation of at least two of the proportional occurrences of the second hail data indicator over the first hail data indicator ranges, yielding a hail intensity number display for the respective range;

retrieving the instantaneous second hail data indicator value from the meteorological data of the corresponding time period and geographic location, further retrieving the hail intensity display number from said hail intensity number display matrix using said instantaneous second hail data indicator value; and

generating a data packet of said hail intensity display numbers, each of said hail intensity display numbers corresponding to a local geographic point.

2. The method of claim 1, wherein said hail data indicators are selected from probability of severe hail, vertically integrated liquid density, maximum size, ground truth, and lowest level radar.

3. The method of claim 1, wherein said hail data indicator pair comprises a first hail data indicator of probability of severe hail and a second hail data indicator of vertically integrated liquid density.

4. The method of claim 1, wherein said hail data indicator pair comprises a first hail data indicator of probability of severe hail and a second hail data indicator of maximum hail size.

5. The method of claim 1, wherein said hail data indicator pair comprises a first hail data indicator of probability of severe hail and a second hail data indicator of lowest level radar returns.

6. The method of claim 1, wherein a range value multiplier is applied to the proportional occurrences.

7. The method of claim 6, further comprising transforming said data packet into a graphical image format.

8. The method of claim 7, further comprising visual map data corresponding to the geographic points of said hail intensity display numbers.

9. The method of claim 1, further comprising generating a second data packet from meteorological data source for subsequent selected time slice.

10. The method of claim 1, further comprising generating a second data packet from said meteorological data source for a subsequent selected time slice, transforming said data packets into a graphical image format, said graphical format comprising an ordered image sequence of said first data packet followed by said second data packet.

11. A method of processing weather data for display comprising:

providing a processor and memory configured to perform the following steps

receiving a meteorological data corresponding to a geographic region from at least one meteorological data source for a storm event;

processing a hail data indicator pair comprising a first hail data indicator of vertically integrated liquid density and a second hail data indicator of probability of severe hail;

a storm event distribution generated using said hail data indicator pair comprising the steps of;

configuring ranges for each of said hail data indicators, tabulating the number of occurrences of data points from the storm event data within the intersecting ranges of said first hail data indicator and said second hail data indicator, and calculating the proportion of occurrences within said intersecting ranges;

a hail intensity number display matrix is calculated using said storm event distribution comprising the steps of;

for each of the second hail data indicator ranges, generating a summation of at least two of the proportional occurrences of the second hail data indicator over the first hail data indicator ranges, yielding a hail intensity number display for the respective range;

retrieving the instantaneous second hail data indicator value from the meteorological data of the corresponding time period and geographic location, further retrieving the hail intensity display number from said hail intensity number display matrix using said instantaneous second hail data indicator value; and

generating a data packet of said hail intensity display numbers, each of said hail intensity display numbers corresponding to a local geographic point.

12. The method of claim 11, wherein a range value multiplier is applied to the proportional occurrences.

13. The method of claim 12, wherein said range value multiplier is a value within the second hail data indicator range.

14. The method of claim 12, wherein said range value multiplier is the upper end of the second hail data indicator range.

15. A system of processing weather data for display comprising:

a processor and memory configured to perform the following steps;

receiving a meteorological data corresponding to a geographic region from at least one meteorological data source for a storm event;

processing a hail data indicator pair comprising a first hail data indicator and a second hail data indicator, said hail data indicators being meteorological data which directly or indirectly indicates hail activity;

a storm event distribution generated using said hail data indicator pair comprising the steps of;

configuring ranges for each of said hail data indicators, tabulating the number of occurrences of data points from the storm event data within the intersecting ranges of said first hail data indicator and said second hail data indicator, and calculating the proportion of occurrences within said intersecting ranges;
