基于微波辐射计资料研究常州地区大气廓线

Research on atmospheric profile in Changzhou based on microwave radiometer data

为了研究常州地区大气廓线,文章利用常州国家基本站地基微波辐射计近1年观测资料,在不同季节、不同天气情况下对观测资料进行数据处理,得出液态水廓线、相对湿度廓线、水汽密度廓线和温度廓线并进行了简要分析。结果表明:常州地区低层大气白天干热、夜间湿冷;水汽密度与相对湿度有较强的相关性;春季与冬季液态水含量空间垂直廓线有明显的双峰,夏秋季表现为单峰,云天在3 km处有峰值,雨天在1 km和3 km处有峰值。研究结果为常州地区降水及灾害预报提供指示意义。

In order to study the atmospheric profile in Changzhou,based on the observation data of ground based microwave radiometer in Changzhou National Basic Station for nearly one year the observation data at different seasons and weather conditions was processed.The liquid water profile,relative humidity profile,water vapor density profile and temperature profile are obtained and briefly analyzed.The results show that the lower atmosphere in Changzhou is dry and hot in the daytime,wet and cold at night.There is a strong correlation between and the water vapor density relative humidity.There ared obvious double peaks in spring and winterd the spatial vertical profile of liquid water,and single peak in summer and autumn.There is a peak at 3 km on cloudy days,and a peak at 1 km and 3 km on rainy days,respectivedy.The research results provide indicative significance for precipitation and disaster prediction for Changzhou.
