| 摘 要： | 本文对2003年4月16～17日发生在浙北沿海的一次10～11级南大风过程进行了诊断分析：发现入海高压的稳定维持和西面低值系统的发展是造成南大风的直接原因，北面冷空气的动力作用和西南急流引起热力降压作用，使地面增温、增湿、梯度堆积，并引起对流发展，使高空动量下传,有利于南大风的出现。

| Abstract: | Through diagnostic analysis of the 10 ~ 11 scale south gale occurred in the north coast of Zhejiang Province on April 16~17 2003, we find that the high pressure moving to the sea preserved stable and the low pressure developing in the west are the direct reasons. Due to the dynamic effect of the cold air in the north and the thermal effect caused by the southwest jet, the temperature of surface raised, the humidity enhanced and the gradient piled up, then the developed convection lead to downward momentum transport, all of these helped to the appearance of the south gale. |
