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 and are capable of producing excessive rainfall totals. Training rain can cause flash flooding.
Types of training
General training
Training may consist of a series of thunderstorms, rain showers, snow showers or snow storms. Training occurring with light rain showers will not cause flooding.
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.
Hazards
Floods
A series of storms continually moving over the same area, dumping heavy rains can cause flooding. 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.
Formation
Showers and thunderstorms along thunderstorm trains usually develop in one area of stationary instability, and are advanced along a single path by prevailing winds. Additional showers and storms can also 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 become too stable for support of thunderstorm activity. Showers and storms can also develop along stationary fronts, and winds move them down the front. The reason why showers often accompany thunderstorms, is because these showers are usually thunderstorms that are not completely developed. All thunderstorms start as showers, then strengthen to thunderstorms. However, the systems that reach certain areas further down the "train" may all be fully developed, even though they start as showers.
Name
It is known as thunderstorm training, because the storms line up along a single line like cars of a train traveling along a track (moving along a single path), without the track moving.
