After all storms are identified, using it is different when time body sweep data storm be tracked, storm
Radar Data of tracking when must have multiple time, time must be continuous when the body of Radar Data is swept.As shown in Fig. 2, wind
Tracking 152 concrete methods of realizing of forecast unit cruelly is：1) by the detection to storm before, a correlation table can be generated；2)
The storm information at the moment compared with correlation table and is matched, all storm bodies when first will be current time are descending according to intensity
Sequence, successively compared with the forecast position of previous all storms, the forecast position of previous storm is also previous for vortex position
What calculating was got；3) former storm deposit sequence is added in the storm of successful match, assigns the I D of previous storm, remaining to press intensity size
The storm of arrangement successively compared with not matched previous storm, terminates, if until most until all current storms all match
Current storm is not all matched afterwards, then it is assumed that the storm is newborn, and assigns new ID, and the storm data of the new life are deposited
It stores up in correlation table；4) by when this of the storm of successful match time information and it is each before when time information comparison, calculate this
The movement speed of storm, direction, and then the position of the storm is forecast, and corresponding data are stored to correlation table
In.It is further comprising the steps of before step 2)：If the time that first time recognizes storm or body is swept twice is separated by too long, it is more than
The threshold values of setting, then without matching, it is believed that current all storms are all new storms, and by respective data storage to correlation
In table, the threshold values for being not above setting is separated by if not the time for recognizing storm for the first time or body is swept twice, then is walked
It is rapid 2).
Storm identifies that with the purpose of tracing module 15 be constantly to be tracked strong convection system, obtains Convective Storms
Secondary attribute when each, to study the feature of strong storm.And need to be tracked the structure of storm, to it is sometimes secondary
