1981-1983年黑潮弯曲和埃尔尼诺事件的个例分析

在统一考虑黑潮大弯曲和埃尔尼诺事件共同存在的条件下,对水位、海水温度和风场进行了分析.结果发现,1981年黑潮发生大弯曲和1982年出现的埃尔尼诺事件均与相应风场相配合,热带风场变化不仅对黑潮变异有直接影响,而且也是判断这次埃尔尼诺事件爆发的重要依据,从而把1982-1983年的埃尔尼诺与1981-1984年的黑潮弯曲密切联系起来.     

黄海、渤海水温垂直结构数值预报方法研究 Ⅰ．一维数值预报模式

本文根据历史水温资料分别建立无维温度θＴ，和无维深度η，进而建立水温垂直剖面的无维自模函数θＴ＝ｆ（η）。在此基础上，利用热传导方程在忽略平流和侧向涡动效应条件下建立描述表层水温（ＴＳ）、底层水温（ＴＨ）和上均匀层厚度（ｈ）的一维模式。利用本模式试报了（时效为５ｄ，１０ｄ，１５ｄ）南黄海２０个站的ＴＳ，ＴＨ，ｈ及温跃层厚度和强度，结果令人满意。     

A PARAMETRIC MODEL FOR THERMAL STRUCTURE FEATURES OF THE OCEAN UPPER LAYER

Based on the non-dimensional general function for the thermal structure features presented by S. A. Kitaigorodsky et al. (1963, 1965)[10,11]. this paper tries to establish semi-empirical and semi-theoretical models bfor the thickness of the upper homogeneous layer of the ocean, thermocline intensity and lower oundary depth of thermocline by consecutive observations from 159 stations in the Bohai Sea,Huanghai Sea and East China Sea in the warm half of the years from 1957 to 1964 and the heat budget at the sea surface computed with the simplified computing formulae proposed by Wang (1983)[22]. This model indicates the main factors forming the thermal structure features in the upper layer of the ocean and their function. With the model, one can directly use the sea surface temperature, air temperature and wind speed to compute the thermal feature in the upper layer of the ocean.
