Abstract: | The variation features of the cross-equatorial flow and its impact on the ridge position of the subtropical high have been analyzed in this paper. It is shown as follows. (1) The intensity of the Somalicross-equatorial flow is increasing in winter and summer in the past 44 years and the airflow of Northem Hemisphere exchanges more and more intensively with that of Southern Hemisphere. (2) The Somalicross-equatorial flow in May has the most impact on the ridge position of the subtropical high in the typhoon season, presenting a positive correlation. (3) The diagnosis is consistent with the real situation in 2005. |
