浅析塔克拉玛干沙漠降水云系特征及演变规律

Basic Characteristics of Rainfall Cloud System and Their Development laws in Taklimakan Desert

文章在分析前人研究成果的基础上,总结归纳了塔克拉玛干沙漠降水云系的基本类型、特征、环流形势和云系演变的一般规律.云系类型归纳起来可以分为四大类:冷锋涡旋云系类,南支槽盾状云系类,大槽、低涡云系类,副热带西风急流云系类.这四类云系只要进入塔里木盆地活动,都会影响塔克拉玛干沙漠降水或大风、沙尘天气.

This paper induce the basic types of “Taklimakan Desert rainfall cloud system and their development laws on the basis of past research achievement. The cloud system may be divided four types： cold frontal vortex cloud system, south branch groove shielded cloud system, big groove and low vortex cloud system,subtropical westerly jet cloud system. If these cloud systems move in Taklimakan Desert,it will result in precipitation,wind or sandstorm weather.
