一、引言 关于太平洋海温与我国江淮水旱的关系,我国气象学者已有过不少研究。早在五十年代初吕炯就指出,太平洋西北隅的水温对长江中下游的旱涝有相当关系,六十年代吕炯等又进一步指出,长江中下游洪水时期亲潮与黑潮同时加强,并指出旱涝时两种截然不同的海水循环。近年来大气所长期组的研究表明,长江中下游汛期降水与前期黑潮地
I. INTRODUCTION With regard to the relationship between the sea surface temperature in the Pacific Ocean and the floods and droughts in China’s Jianghuai Basin, many meteorological scholars have studied it. As early as the early 1950s, Lv Jiong pointed out that the water temperature in the northwestern Pacific has a great relation to the drought and flood in the middle and lower reaches of the Yangtze River. In the 1960s, Lu Jiong et al further pointed out that the pro-tide and the Kuroshio in the middle and lower reaches of the Yangtze River strengthened at the same time, And pointed out two distinct cycles of seawater during droughts and floods. In recent years, the long-term study of the atmosphere shows that the precipitation in flood season in the middle and lower reaches of the Yangtze River is similar to that in the early Kuroshio
