摘要
应用卫星云图、常规观测资料及T213数值分析产品,分析了2004年12月3-5日发生在浙江东部地区的暴雨和舟山市沿海的大风过程。分析结果表明:这次天气过程是由台风倒槽和冷空气及深厚的高空槽共同作用引起的;台风环流引起的东南低空急流为暴雨区输送了大量的水汽和不稳定能量;冷空气的侵入加上深厚的高空槽引起的低空辐合、中高层辐散,促使了东海低压的剧烈发展,产生了猛烈的大风。
By using conventional observation data, satellite cloud data and T213 numerical Analysis Production, the weather process of the storm rainfall and strong wind from December 3 to 5 in 2004 over Zhoushan city is analyzed. The results show that the weather process occurs because of Typhoon trough with cold air, deep upper trough; the southeast low-Jet by Typhoon transported large water vapour and great energy of instability to heavy rainfaill area; cold air, lower convergence and upper divergence by deep upper trough lead to development of the east-ocean low pressure and occurd strong wind.
