| 摘 要： | 运用MICAPS常规资料对2008年4月的透雨过程进行了分析。这次降水是高空槽东移、低空低涡和地面低压北上共同作用的结果。低空低涡北上为降水带来了充裕的暖湿气流；高空槽东移带来的冷空气为后续降水的持续与加强提供了动力条件；前期持续的偏南大风为降水提供了有利的热力条件。而日本气象中心、欧洲气象中心和国家气象中心对这次降水的预报准确而且一致，有利于准确判断降水的强度和起始时间。

| Abstract: | Based on MICAPS conventional data,the process of soaking rain in April 2008 was analyzed.This precipitation process was the combined effect of upper trough moving eastward,low vortex and low pressure northward.Northward low vortex brought plenty of warm flow.Upper trough brought cold air to provide dynamic conditions of precipitation to strengthen and continue.The stronger southerly wind provided a favorable thermodynamic condition.The precipitation forecasts of Japanese Meteorological Center,European Meteo... |
