| 摘 要： | 采用统计诊断和数值试验方法讨论了赤道东太平洋海温异常对东亚夏季大气环流异常的影响，研究表明赤道东太平洋海温的持续异常，引起南海－菲律宾附近地区对流异常的持续，从而导致东亚大气环流的持续异常；同时指出春季赤道东太平洋海温异常和夏季海温异常对夏季东亚大气环流的影响并非是线性叠加，海温持续性异常对东亚夏季气环流的影响在季节时间尺度上存在非线性相互作用。

| Abstract: | The influence of equatorial eastern Pacific SSTA on summer circulation in east Asia is studied with the aid of statistical method and model test.On account of the sustained anomaly of the equatorial eastern Pacific SST,the abnormal convection is maintained around the South China Sea to the Philippines,which leads to the continued anomaly of summer circulation in east Asia.The influence on summer circulation in east Asia of the spring and summer SSTA in the equatorial eastern Pacific is not simply a linear superposition,but a nonlinear interaction on a seasonal scale. |
