The aim of the study was 1)to determine the relation between the Kuroshio meander and the intensity of the subtropic high pressure over the Pacific Ocean

and then to obtain statistical validity for the observational conclusion that the occurrence time of the Kuroshio meander leads the time of strengthened C-circulation of Europe by one or more years; 2) to develop a method to predict the occurrence time of flood or drought periods in the Changjiang River Valley from the occurrence time of the Kuroshio meander

since there is a close relation between the occurrence time of the drought or flood periods in the Changjiang River Valley and the occurrence time of the strong or weak periods of C-circulation of Europe; and 3) to develop a logical explanation verifiable by remote sensing technique and other means that the warm species phytoplanktons collected recently in the Jiaozhou Bay of Shandong Peninsula in China were carried there by a new warm current branch of the Kuroshio in the East China Sea.
