一、引 言 在海洋学,气象学和海气相互作用的研究中,海洋表面温度起着十分重要的作用,也是最容易得到的海洋基本参数,开展东海表面水温实况分析业务,是为海洋渔业部门直接服务的重要项目之一, 为此,国家海洋局东海分局上海海洋环境预报区台自从1986年7月起为100多个水产、渔业及有关研究单位提供了“东海海面月平均水温实况分析图”,受到了广大用户的欢迎。 众所周知,东海水文状况复杂,这与该海域流系交汇和海气热交换过程复杂有关。黑潮流系与沿岸流流系相汇成明显的海洋锋区(流隔区),使海洋要素变化出现不连续现象。为了更好地分析和反映东海海面温度场的特征,我们采用了主客观分析相结合的方法。
I. INTRODUCTION In the study of oceanography, meteorology and air-sea interaction, the surface temperature of the ocean plays an important role and is also the most readily available basic parameter of the ocean. To conduct the live analysis of surface water temperature in the East China Sea, Direct service of one of the important projects, to this end, the East China Sea Branch of the State Oceanic Administration Shanghai Marine Environment Forecasting District since July 1986 for more than 100 aquatic products, fisheries and related research units provided “the East China Sea monthly average water temperature live analysis ”, By the majority of users. It is well-known that the hydrological status of the East China Sea is complex, which is related to the complicated flow regimes and the heat exchange process of the sea-air in this area. The Kuroshio and the coastal streams converge into obvious frontal areas (flow compartments), causing discontinuous changes in oceanic elements. In order to better analyze and reflect the characteristics of the sea surface temperature in the East China Sea, we use a combination of subjective and objective analysis.
