新疆降水研究进展综述

Review of study on precipitation in Xinjiang

新疆位于亚欧大陆中心,属于大陆性气候,降水具有明显的地域特色,降水机制与季风区截然不同。本文系统回顾总结了近40 a来新疆降水的研究进展,重点对新疆降水的标准、时空分布特征、天气环流背景、水汽输送、降水动力机理及降水系统结构研究以及数值模拟方面进行回顾。在总结归纳基础上,提出了目前新疆降水研究需要重点关注的几个方向,包括新疆降水的水汽源汇结构及输送机制、中尺度系统的结构和地形对其动力过程的作用等。

Located in the center of Eurasian continents, Xinjiang＇s climate belongs to continental climate. Its precipitation has obvious regional features and differs from the monsoon region. This paper systematically reviewed and summarized the achievement of studies on precipitation in Xinjiang in the recent 40 years. Special attention is paid to the standard of precipitation, climate characteristics, weather circulation background, the mechanism of water vapor transport, precipitation system structure as well as numerical simulation in Xinjiang.On the base of induction and summary, several directions for the study of precipitation in Xinjiang are raised, including structure of water vapor source, mechanism of water vapor transport, structure of mesoscale system and the role of topography in dynamic process.
