摘要
用ＩＡＰ－ＡＧＣＭ气候模式、功率谱分析、带通滤波等方法对北半球５－７月副热带高压季节性北跳进行了数值模拟和处理，得出：赤道中太平洋、西太平洋、印度洋海温异常以及北极海冰的异常对副高的季节性跳动都有不同程度的影响，对西太平洋副高尤为突出，其中海温的影响较为显著；证实了太平洋和印度洋跳源的存在；其影响过程可能是通过其激发出的低频波来实现的。
? In this paper,by using the techniques for IAPAGCM climate model,power spectral analysis and bandpass filter numerical simulations of the effects of seasonal northward jumping of subtropical high during May to July in Norther Hemisphere.It is shown that the SST anomaly of equatorial mid Pacific、western Pacific、Indian ocean and northern polar ice anomaly there are influenced by it ,with greater degree on seasonal jumping of subtropical high and the influence of SST is most evident. And the jumping sources are confirmed in Pacific and Indian Oceans. Its influence process is possibly realized by arousing low frequency wave.
