| 摘 要： | 本文通过ＩＡＰ－ＧＣＭ的数值模拟，研究了全球大气环流对黑潮海域和赤道东太平洋冬季ＳＳＴ异常的响应，并着重比较东亚大气环流和气候对黑潮区ＳＳＴＡ的响应（邻响应）和对赤道东太平洋ＳＳＴＡ的响应（遥响应）。首先，无论是黑潮区ＳＳＴＡ引起的邻响应还是赤道东太平洋ＳＳＴＡ所引起的遥响应对东亚大气环流和气候变化的影响都是明显而重要的。由于在大气中低频振荡被激发出来，其响应将持续较长时间。进一步分析表明，东亚大气环流对黑潮区或赤道东太平洋冬季正ＳＳＴＡ的响应都将造成华北地区夏季的多雨，其数值模拟结果与观测相一致。另外，赤道西太平洋地区大气的异常（尤其是对流活动）对于东亚地区大气环流和气候变化有重要作用

| Abstract: | By using numerical simulation in IAP-GCM, the global atmospheric circulation responses to the SSTA in the Kuroshio region and in the equatorial eastern Pacific in winter are studied. In this paper, the focus is comparison of the responses of the East-Asian circulation and climate to the SSTA in the Kuroshio region (border responses) and in the equatorial eastern Pacific (remote responses). At first, for the atmospheric circulation and climatic variations in East Asia, both the border response and the remote response to SSTA are all obvious and important. Since exciting the low-frequency oscillation in the atmosphere, the responses will continue for a longer time. The further analyses show that the responses of the East-Asian Circulation to positive SSTA in the Kuroshio region or in the equatorial eastern Pacific in winter are all the same to cause more precipitation in Huabei region in summer. And these simulated results are consistent with the observations. The tropical atmospheric anomalies over the equatorial western Pacific seem to be important to the climatic variation in East Asia. |
