中文摘要: 利用MICAPS实时探空资料,将单站大气逆温转换成逆温水平分布区,实现了大气逆温水平分布的自动诊断分析;通过对大气逆温水平分布与冻雨落区关系的研究,提出了由大气逆温水平分布区、高空湿区、地面气温0 ℃线、逆温层极值点0 ℃线构成的冻雨落区的基本概念模型;根据基本概念模型研制出了冻雨落区的自动诊断分析方法。在对2008年初我国南方冰冻天气的检验中表现出较强的诊断分析能力,有较好的业务应用前景。
Abstract:Using MICAPS real time sounding data, the atmospheric inversion layers of single stations were converted into atmospheric horizontal inversion zone and the automatic diagnostic analysis of the latter was achieved, by researching the relationship of atmospheric horizontal inversion zone and freezing rain falling zone. Afterwards, the atmospheric horizontal inversion zone, high altitude wet areas, the ground air 0 ℃ line, and the 0 ℃ line of extreme temperature of inversion layer, were used to constitute the basic conceptual model of freezing rain falling zone; furthermore, on the basic conceptual model, the automatic diagnostic analysis method of freezing rain falling zone was developed and was tested in the severely freezing weather in southern China early 2008. The method shows the strong diagnostic analysis ability and has good prospects for operational applications.
