摘要

Abstract

1.On the basis of the analysis of hydrographical and geological data it is concluded that the cyclonic eddy in the northern East China Sea existed every year and season. However

it was deduced from its monthly changes that it did not exist all the time. li]2.|Conspicuous internannual

even monthly changes of the eddy in summer were found. The main cause for it was the strength and position of HWC and HCC. As for its seasonal change

reliable analysis was hard to make. However

from Fig. 2 and taking into account the change of the strength of HWC and HCC it seems that the eddy was strongest with southmost centre in winter and weaker (compared with winter) with north-most centre in summer. li]3.|More often than not

the eddy occurred in intermediate layer. The distructive effect of the wind might be the cause for the eddy's not reaching the surface in spring

fall and winter

and the Changjiang Diluted Water might have played the same role in summer. li]4.|The average position of the eddy was

upon the whole

coincident with the mud's—the multiyear existence of the eddy was determinant for the mud formation. li]5.|The disposition of HWC

HCC and NRK was the main dynamical factor for the eddy formation. Among others

HWC and HCC were decisive and the occurrence of bottom cold water in summer may intensify the eddy as a thermodynamical factor.
