摘要:

大气风场是研究气溶胶输送与复合过程以及时空分布变化研究的一个重要方面,也是天气分析和天气预报中的一个重要参数。文章采用对流层风廓线雷达,连续测量合肥地区对流层大气风场。统计了2009年合肥地区风场变化,得到了一些统计结果:边界层(2 km以下)风速基本小于5 m/s,风向变化复杂,不同季节风向略有不同;对流层风速多在5~25 m/s之间,以西北偏西风为主导风向,年最大风速超过60 m/s。文章还以2008年梅雨季节风场探测资料为例,分析了梅雨期中不同高度的风场演变过程。

关键词: 风场, 风廓线雷达, 梅雨季节, 统计分析

Abstract:

Atmospheric wind field is an important side in researching the process of aerosol transporting and compounding, and the diversification of aerosol space-time distributing. It is also an essential parameter of the synoptic analysis and weather forecast. The structure and theory of sounding system of wind field—wind profiler radar was introduced. From analyzing the data in plum rain season, the evolving of wind field in one synoptic process was observed. And from the statistics of wind field in 2009, Hefei, it could be concluded the following points. In the boundary layer (under 2 km), the wind velocity was below 5 m/s, and the wind direction was complex and had some diversity in different seasons. In the troposphere, the wind velocity was generally between 5 m/s and 25 m/s, and the predominant wind direction was west wind. The maximum wind velocity had exceeded 60 m/s.

Key words: wind field, wind profiler radar, plum rain season, statistics
