中文摘要: 利用常规天气资料、加密探空资料、地基微波辐射计资料和气象卫星资料,结合数值模式MM5V3分析了2002年10月19日河南省层状云降水人工增雨潜力。资料分析表明,这次降水过程的潜力区主要分布在700~300 hPa高度上,07:00、13:00和16:00时刻;从数值模拟结果看,增雨潜力的时空分布同探空分析大体上一致,云系中含有比较丰富的过冷水,冰晶粒子浓度不是很多,这种水成物的配置存在引晶催化的增雨潜力,有利于降水的形成。
Abstract:The characteristics of water vapor conditions of stratiform cloud and its potential for rainfall enhancement in the autumn 2002 in Henan Province have been investigated by means of data from meteorological observation, from upper air soundings at 3 h intervals, and from Ground Based Dual Wavelength Microwave Radiometer (GBDWMR) system and meteorological satellite and combined with the results of MM5V3. It is shown from the analysis of those data that the main positions of potential are located at the 700-300 hPa level at 07:00, 13:00, 16:00 BT moment. As the result of model simulation, it is beneficial for the formation of rain in which the content of supercooled liquid water is abundant while the number concentration of ice crystal is little.
