Abstract

The subject invention relates to weather forecasting systems which can predict the direction of a storm'"'"'s movement. More particularly, the invention will receive and record weather data from any of a variety of weather data sources. The invention will then allow a user to request a storm tracking prediction, and graphically display said prediction with a high degree of accuracy. The weather data is stored in a time-tagged fashion. By storing the weather data in a time-tagged fashion, the weather system constructs an easily accessible weather database containing the locations of storms and other weather phenomena as a function of time. The weather system provides a Graphical User Interface which allows the user to call up a graphical representation of current weather data being supplied to the weather system. The weather system also provides the user with the ability to call up a graphical representation of any of the time-tagged historical weather data stored in the weather database. Then, by invoking some prediction algorithm, such as a linear extrapolation or other similar function, the weather system is able to calculate and display a projection of the selected storm'"'"'s path from its current location.

Claims

1. A method of using weather data to graphically display a weather phenomenon'"'"'s predicted future path, said method comprising the steps of:

a) collecting weather data over a period of time, said weather data corresponding to a weather phenomenon and including a weather phenomenon location and a time,

b) associating the weather phenomenon location with geographical information and storing the weather phenomenon location in a computer memory by its time to create a historical weather data database;

c) displaying current collected weather data corresponding to said weather phenomenon as a current graphical representation of said weather phenomenon on a display device together with said geographical information;

d) requesting said historical weather data for a particular time;

e) displaying said historical weather data on said display device as a historical graphical representation of said weather phenomenon;

f) selecting a first reference point on said historical graphical representation of said weather phenomenon with an input device;

g) automatically updating the graphical display in response to said selecting step to display a then current graphical representation of said weather phenomenon;

h) selecting a second reference point on said then current graphical representation of said weather phenomenon;

i) calculating an predicted fixture path of said weather phenomenon; and

j) displaying a graphical representation of said predicted future path of said weather phenomenon on said display device.

2. The method of claim 1 wherein said step e) comprises the step of replacing said current graphical representation of said weather phenomenon with said historical graphical representation of said weather phenomenon.

3. The method of claim 1 wherein step i) comprises the steps of:

determining a distance between said first reference point and said second reference point;

determining an elapsed time between receipt of said requested historical weather data and receipt of weather data corresponding to the then current graphical representation of said weather phenomenon; and

calculating velocity using said distance and said elapsed time.

4. The method of claim 3 further comprising the steps of selecting a future time of interest and calculating a velocity vector corresponding to said future time of interest via linear extrapolation.

5. The method of claim 4 wherein step j) comprises the step of displaying said velocity vector on said display device.

6. The method of claim 5 further comprising the step of displaying communities in the predicted future path of said weather phenomenon.

7. The method of claim 6 further comprising the step of indicating the estimated time of arrival of said weather phenomenon for each said community.

8. A system using weather data to graphically display a weather phenomenon'"'"'s predicted future path, said system comprising;

a) at least one communication port for receiving weather data over a period of time, said weather data corresponding to a weather phenomenon and including a weather phenomenon location and a time;

b) a computer memory for storing geographical information and received weather data, said received weather data stored in said computer memory comprising historical weather data;

c) a CPU communicating with said at least one communication port and said computer memory to associate said weather data with said geographical data and to store said weather data by time;

c) a display device communicating with said CPU to graphically display said geographical information and current received weather data corresponding to said weather phenomenon;

d) an input device communicating with said CPU and said display device to select said historical weather data for a particular time at the request of a user, wherein said display device displays a historical graphical representation of said weather phenomenon for that particular time, and to select a first reference point on said historical graphical representation at the request of a user, wherein said CPU automatically updates the graphical display depicted on said display device to display a then current graphical representation of said weather phenomenon, and to select a second reference point on said then current graphical representation of said weather phenomenon at the request of a user, whereby said CPU calculates an expected future path of said weather phenomenon, and whereby said display device displays a graphical representation of said expected future path of said weather phenomenon.

9. The system of claim 8 wherein said CPU calculates a distance between said first reference point and said second reference point, and calculates an elapsed time between receipt of said requested historical weather data and receipt of weather data corresponding to the then current graphical representation of said weather phenomenon, and thereafter, calculates velocity using said distance and said elapsed time.

10. The system of claim 9 wherein said CPU calculates a velocity vector via linear extrapolation, said velocity vector corresponding to a future time of interest selected by a user.

11. The system of claim 10 wherein said velocity vector is displayed on said display device.

12. The system of claim 11 wherein said CPU determines communities in the path of the predicted future path of said weather phenomenon.

13. The system of claim 12 wherein said CPU calculates an estimated time of arrival of said weather phenomenon for each said community.
