Training (meteorology)
In meteorology, training denotes repeated areas of rain, typically associated with thunderstorms, that move over the same region in a relatively short period of time. Training thunderstorms are capable of producing excessive rainfall totals, often causing flash flooding.[1] The name training is derived from how a train and its cars travel along a track (moving along a single path), without the track moving.[2]

[edit] Formation
Storm trains usually develop in an area of stationary instability, and are advanced along a linear path by prevailing winds. Additional storms may develop when the gust front from a storm collides with warmer air outside of the storm. The same process repeats in the new storms, until overall conditions in the surrounding atmosphere shift.
[edit] Hazards
A series of storms continually moving over the same area, dumping heavy rains can cause flash flooding.[1] Each storm usually produces heavy rain, and after a significant amount of rain falls from the storms which have moved over the same area, flooding occurs.
[edit] Thunderstorm training
Thunderstorm training is used to refer specifically to training occurring with thunderstorms. This type of training can quickly cause flash flooding, especially if the thunderstorms are strong or severe.
