Non-precipitationecho from radar such as ground objects echo and super refraction and so on are important to explore quantitatively precipitation and the other products.
The asymmetrical radarecho structure of typhoon exerted impact on its motion and precipitation distribution. The short-time strong rainfall might occur easily in the sudden turning of typhoon.
台风形成的不对称结构影响其移向和降水分布，路径突转时极易产生短时强降水。

The radar echoes for those MCSs are organized well, and some MCSs are moving, others are quasi-stationary. The echo distributions of MCSs indicate the precipitation areas.
