摘要
本文系统地回顾了半个多世纪以来高原切变线特征,切变线形成的大尺度背景场,切变线维持移动机制,切变线与其它系统相互作用机制,以及切变线对降水的影响等方面的研究成果。同时指出高原切变线研究存在着许多薄弱的地方,在降水的不同阶段切变线起着怎样的作用,切变线活动对我国持续性强降水的影响,切变线的云系特征,冬季切变线活动特征及对天气的影响,切变线的东移机制,切变线与不同层次,不同纬度,不同尺度系统之间的相互作用机制研究等方面有待进一步加强。
Studies on plateau shear - line characters, large - scale background, the shear - line maintaining and moving mechanism, reciprocity mechanism between the shear - line and other weather systems, as well as the effect of the shear - line on precipitation over more than half century have been reviewed by the numbers. The article pointed out the researches on plateau shear - line are very lack, such as the shear - line function at different stages of precipitation, the effect on durative precipitation in our country, the shear - line cloud characters, the shear - line active characters in winter, the effect of the shear - line on weather, eastward moving characters, as well as reciprocity mechanism between the shear - line and weather systems on different layer, different latitude and different scales and so on. The researches on plateau shear - line need to be intensified further.
