摘要
连阴雨雪开始前,高空形势有一次大的调整,实际上就是大气长波和超长波的剧烈转换,通常称为大气环流调整。通过对2006年11月连阴雨的时空分布和大气环流的特征,探讨了形成连阴雨的水汽、动力和热力学条件并结合659、5图预报指标,提前预报出此次连阴雨过程,为秋季连阴雨的中期天气预报提供参考。
The atmospheric circulation at upper air would have large adjustment before the long continuous cloudy-rainy days occurS.Actually it is the transition of ultra long wave circulation with long wave circulation. Generally it is called that adjustment of circulation. In this paper, we studied spatial and temporal distribution of continuous cloudy-rainy weather in Nov.2006 and the feature of atmospheric eirculation and the vapor,dynamical and thermodynamic condition was analyzed during the continuous cloudy-rainy days, At the same time, the ＂95,65 graph＂ was been used. This continuous cloudy-rainy weather was forecasted well. The studies provided the reference for medium-term weather forecast of continuous cloudy-rainy weather in Autumn.
