MM5模式对2008年1月25—30日我国南方强冰雪过程的数值模拟

Numerical Simulation by Mesoscale Model MM5 on the Severe Snow and Freezing-Rain During 25—30 January of 2008 Over the Southern China

摘要: 利用NECP1°×1°6h再分析资料,分析2008年1月25—30日我国南方一次强降雪天气的大尺度环流形势。结果表明,高空环流波动为此次强降雪提供了有利的高空环流形势,中低层阻塞高压及其南部低涡的长期维持是导致低层锋区形成和强降雪发

Abstract: Using NECP 1°×1° 6 h data,it can be seen from the analyses of large-scale circulation of a heavy ice-damage in January 2008 that the disturbance in upper air offers the advantage circulation pattern for heavy
