【摘要】 <正> 引 言 分析研究海水温度日变化的特点,对海况分析及了解海区水文基本特征具有重要的意义,特别是对水温日变化很显著的浅海区域更为重要.此外,从渔业意义上来看,了解水温日变化对鱼类昼夜分布和移动规律的影响亦极其重要。 目前的海洋调查,仍以单船进行大面或断面定点观测为主,这样就必须考虑到由于逐站的观测日期和时间的不同所产生的误差。在深海和大洋中,由于水温年变化和日变化均更多还原

【Abstract】 In the present paper, the data of sea-water temperature collected from 495 continuously-working observation stations was sorted out, with the emphasis on the description of space distribution and seasonal yariaition in daily range and the time in which the extremum of daily variation occurred. The leading factors influencing dajly variation of sea-watar temperature were preliminarily discussed. The knowledge of characferisfics and basic conditions of daily variation of sea-water temperature in the Bohai Sea and inshore region of Huanghai Sea and East China Sea has been acquired on analysis.更多还原
