摘要
文中研究了热带西太平洋暖池和西太平洋副热带高压的季节性变化和年际变化关系。结果表明，西太平洋暖池面积和副热带高压面积指数季节变化趋势基本一致，暖池中心的纬向移动与副热带高压西伸脊点相反，而经向移动和５００ｈＰａ副热带高压脊平均位置的南北季节性变化非常一致。西太平洋副热带高压的年际变化落后暖池大约３个月左右，用暖池２８℃或２９℃面积指数可以很好地预测出当年６，７，８三个月西太平洋副热带高压的面积指数。
The relationship of seasonal variation and interannual change between tropical western Pacific warm pool and western Pacific subtropical high have been discussed. The seasonal variation trend of western Pacific warm pool area is the same as that of subtropical high area. The latitudinal translation of warm pool center is contrary to the westward ridge point of subtropical high, while the longitudinal translation is same as 500 hPa mean position of subtropical high in seasonal variation. Western Pacific subtropical high falls behind warm pool about 3 months in interannual change. Western Pacific subtropical high area index in June, July and August can be predicted well by using warm pool area index of 28℃ or 29℃ for the same year.
