摘要
层状云是中国北方大部分地区降水的主要云系,采用综合观测资料的分析研究并结合最新的数值模式对层状云特征和降水机制进行深入研究很有必要,也是含后工作的方向。描述了层状云的种类、特点,通过分析机载PMS(粒子测量系统)资料和地面雨滴谱资料介绍了国内外在层状云云滴谱、冰晶谱、雪质粒谱、雨滴谱、云中质粒总谱等微物理特征方面的研究方法及成果,还介绍了国内外在层状云降水机制方面的研究方法及成果,包括层状云降水数值模拟以及暖云降水机制和冷云降水机制研究。
Stratiform clouds are the main precipitation system in most parts of North China. It is necessary to combine the analysis of composite observation data with the new numerical models to study further the characteristics and precipitation mechanisms of stratiform clouds. The categories and characteristics of stratiform clouds are described. The research methods and main findings in researches on microphysical characteristics at home and abroad in such areas as cloud drop spectrum, ice crystal spectrum, snow particle spectrum, raindrop spectrum and total particle spectrum are discussed through analyzing airborne PMS data and surface raindrop data. In addition, the researches methods and main achievements in stratiform cloud precipitation mechanism researches are also introduced, including stratiform cloud precipitation simulation and cold and warm cloud precipitation mechanism researches.
