风廓线雷达在高空风场分析中的应用
Application of Wind Profile Radar in Upper Wind Analysis
摘要
Abstract
Characteristics of Horizontal and vertical wind flow at each layer were analyzed by use of wind profile radar observation data in 2011 at DaIian.It had been found that the layer of maximum horizontal wind speed was usually about 12 km.There was a significantly annual change of wind speed with height below 4km.While the wind speed increased with increasing height from 4 km to the layer of maximum wind speed.The horizontal wind speed first decreased and then increased with increasing height from 12 km to the radar measurement—supper.The average vertical wind was the biggest in summer and the smallest in winter and spring.The monthly vertical wind speed was the maximum in June and the minimum in February.There was an updraft center in 500～1300 m level,the average vertical wind speed was greater than 0.6 m/s.关键词
