摘    要:利用1997年春季西宁市地基双通道(22.235和35.3GHz)微波辐射计观测的资料,分析了不同月份、不同天气条件下的大气总含水量(V)和云中液态水积分含量(L)的分布规律。结果表明,在相同天气条件下,L值3-5月均呈逐渐递增的趋势,增加幅度一般为20%-40%,V值变化幅度很小;春季高原L值大约只有V的1%。与河北省的资料进行对比后发现,L值基本相当,而V值高原只有平原地区的30%-50%。

关 键 词:微波辐射计 液态水 汽态水 青藏高原 大气

Abstract:Based on the data obtained with a ground based dual channel microwave radiometer in Xining, Qinghai Province, during spring season in 1997, the total cloud water vapor( V ) and cloud liquid water ( L ) are analyzed for different months and weather conditions. The results show that, for the specified weather conditions,the values of L increase gradually from March to May at a growth rate of 20~40% per month while the values of V have no significant variation.The cloud liquid water content is only about 1% of the water vapor content in the atmospheric column. Comparison of the observed data from the Tibetan Plateau with the data from Hebei Plain shows that there are no significant differences in the cloud liquid water content between these two areas, but the V over Xining is higher than that over Shijiazhuang by about 30%~50%.
Keywords:microwave radiometer  cloud liquid water  water vapor content  Tibetan Plateau
