摘要：

The microphysical processes' spatial variety and temporal evolution tendency during super typhoon Leima is investigated through measurements from an S-band polarimetric radar and six disdrometers. The results show that collision-coalescence/the collision-breakup occurred near/around the center of the typhoon, deduced from radar-measured and DSD-derived ZDR. In the vertical time-series view of ZDR, the collision-breakup may transition to the collision-breakup near the surface around the altitude of 0.9 km, and the collision-coalescence, collision-breakup, and coalescence-breakup balance may dominate during different periods of typhoon precipitation.
