摘要
通过对大量天气图和几次典型个例天气状况的分析研究,归纳总结出吉林地区地面冷、暖锋有无降水的几种非常规高空和地面天气形势。提出温度场是影响天气变化的主要要素场,分析研究高空不同温压场配置中的冷暖空气的运动状况,是做好锋面降水天气预报的关键。
According to the analysis of weather situation of mass weather chart and several typical cases,some unconventional weather situations of ground cold or warm front with or without precipitation upper air and ground were summarized.The results showed that temperature field is the main element field affects the weather variation.The analysis of cold and warm air＇s movement with different temperature-pressure field upper air is the key of frontal precipitation＇s forecasting.
