摘要:

测量大气湿度廓线对短时天气预报和长期气候分析有重要意义,概述目前探测大气湿度廓线的几种方法,指出这些方法存在的一些问题,突出风廓线雷达测量大气湿度廓线的优越性。论述风廓线雷达反演湿度廓线的理论,利用合肥2009年9月29日三个时间段的风廓线雷达数据和探空数据,通过计算雷达测得的大气湍流耗散率和探空得到的温度廓线,分析计算得到三个时刻的湿度廓线,能够得到比较可信的结果,显示利用风廓线雷达反演湿度廓线是可行的。

Abstract:

Measurment of atmosphere humidity profile is important for short time weather forecast and longtime climate analysis. There are several methods to measure atmosphere humidity profile, but they have disadvantages in different regions. Wind profiler radar has superiority in measuring humidity profile. The theory of wind profiler radar estimating atmosphere humidity profile is discussed. Based on the wind profile radar data and air sounding data of three timescales on 29, September 2009, the atmosphere humidity profile of the three timescale is estimated through calculating the atmosphere turbulent dissipation rating by using wind profiler radar and the temperature profile by using air sounding data. The result is very reliable. Using wind profiler radar to estimate atmosphere humidity profile is feasible.

Key words: wind profiler radar, atmosphere humidity profile, air sounding, turbulent dissipation
