The further study reveals that the enhancement (northward movement) and westward shift of the Subtropical High over the middle Pacific are closely related to the abnormally active convection in the ITCZ to the south and over the northern Bay of Bengal.

• 进一步分析表明 ,在太平洋中部副热带高压的增强北跳和西伸之前 ,副热带高压南侧ITCZ中对流和孟加拉湾北部的对流活动明显并且都经历了一次增强活跃过程 ,这意味着热带ITCZ和孟加拉湾北部对流的异常活跃可能对副热带高压的增强北跳西伸产生影响。
