摘　　要：本文利用月平均资料对黑潮海表水温与我国汛期(5—8月)降水进行了相关分析,指出前期(1至4月)海温与汛期降水相关场大致呈稳定的纬向分布。对海温与东亚低阶流场谱分析表明,该海域海温对西太平洋副高强度的滞后响应较明显。Based on the monthly mean data, the relationship between precipitation in China during rainy season (from May to Aug.) and Sea Surface Temperature at Kuroshio Region (SSTKR) are analysed. The analyses show that the correlative fields are characterized by quasi-zonally pattern. By using cross spectrum method, the interaction of SSTKR and main ciculation over the East Asia are discussed. The results indicate that SSTKR strongly responds to the Western pacific Subtropic High(WPSH), while WPSH weakly responds to SSTKR when |<|τ|<5.
