In the variation of west-east position of subtropical high, the Indian Ocean SST has a stronger effect than the North Pacific SST, with correlation area mainly distributed in the neighbouring of the confluentce of warm and cold currents.

• 对副高东西位置变动,印度洋海温的作用强于北太平洋海温,相关区主要都分布在冷暖海流交汇处附近。 两大洋与副高长期变动的相关敏感区的起迄时间大体上与大洋上空大气环流的转换期相对应。
