متن کاملTropical Rain Classification and Estimation of Rain from Z-r (reflectivity-rain Rate) Relationships
A Z-R relation is derived using a data set which consists of nine rain events selected from Singapore’s drop size distribution. Rain events are separated into convective and stratiform types of rain using two methods: the Gamache-Houze method, a simple threshold technique, and the Atlas-Ulbrich method.
