Quasi-Stationary Convective Events

Quasi-stationary, or very slowly moving, storm systems are of particular interest to the forecaster, because they frequently produce heavy rainfall and flash floods. These convective weather systems are composed at any moment of many individual storms, all in various stages of their life cycles. The individual storms frequently have trajectories that carry them repeatedly over the same region, producing pulsating heavy rains that quickly cause streams and rivers to overflow their banks. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
