摘　　要：本文利用NCEP1°×1°的网格点分析资料和常规观测资料对2006年1月4～7日广东寒潮造成的广东海面8级大风过程进行了物理机制分析。结果表明:受强冷空气南下影响,有着较深厚的强冷平流输送,加之高空动量下传的共同作用,故而造成了广东东、西部海面先后出现了8级大风过程。这为以后更准确地预报广东海面大风提供了良好的依据。Based on NCEP 1 ° ×1 °data and conventional observation data, the strong gale of cold wave happened in Guangdong on 4-7th January 2006 was analyed. The results showed that the strong and deeper cold temperature advection transportation and momentum transportation downward were the main reasons for causing gale wind along the Guangdong coast. Analysis results may help to do the more exact forecast for the gale wind along the Guangdong coast.
