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. 相似文献

大连老虎滩澳的大振幅假潮 总被引:3,自引:0,他引:3
潮汐周期以外的大振幅水位波动(即大振幅假潮),在老虎滩澳时有发生。老虎滩澳位于大连湾侧,是一半封闭深度较浅的三角形小海湾(图1).验潮站位于湾的左岸,距湾顶约1km,水深2.8m.据统计,1980~1994年15年间出现波高大于20cm的假潮共61次。波高超过40cm的为12次。较大振幅事件发生在1994年7月3日,其最大波高为91cm,谱分析显着周期为10min.类似这种小海湾的大振幅假潮在世界其他港湾也经常观测到。其中,以中国的龙口港、日本的长崎港和巴利亚里群岛西岸的锡尤达德拉(Ciu-tadella)港发生的大振幅假潮最为突出。 相似文献
