本文分析美国国家大气研究中心(NCAR)的CCM3-ML耦合模式100a积分模拟结果,依据对该模式结果中SSTA与海面风异常的最大协方差分析,证实的确存在北太平洋局地大气影响海洋和海洋“反馈”大气的主模态;指出通过局地海洋一大气的相互作用,冬季马蹄型海温异常可以持续到夏季,冬季大气对马蹄形暖海温异常可能的响应为高压异常,春夏季对马蹄形暖海温异常可能的响应为低压异常。
By using NCAR CCM3-ML coupled model result (one hundred year), based on Maximum Co- variance Analysis between the monthly sea surface temperature anomaly (SSTA) and the sea surface wind anomaly, the dominate modes of local atmosphere influences ocean and ocean feedbacks on atmosphere in North Pacific are confirmed to exist;It is indicated that horseshoe SSTA pattern in winter can persist to summer through local atmosphere-ocean interaction. The atmosphere response to the horseshoe SSTA is warm/high in winter and warm/surface low in spring and summer in North Pacific.
