| 摘 要： | 通过分析索马里越赤道气流的变化特征及其对7-9月副高脊线位置的影响关系,结果表明：（1）在近44年来冬、夏季索马里越赤道气流强度都呈增强趋势,具有南北半球气流交换越来越激烈之事实;（2）5月索马里越赤道气流对7-9月环流影响关系最好,与副高脊线位置的影响呈正相关关系;（3）2005年诊断与实况相符。

| Abstract: | The variation feature of the cross-equatorial flow and its impact on the ridge line position of the subtropical high were analyzed in this paper.It was shown as follows.(1) The intensity of the Somali cross-equatorial flow was increasing in winter and summer in the past 44 years and the airflow of Northern Hemisphere exchanged more and more intensively with that in Southern Hemisphere.(2) The Somali cross-equatorial flow in May had the most impact on ridge line position of the subtropical high in the typhoon season,presenting a positive correlation.(3) The diagnose was consistent with the real situation in 2005. |
