黄海、渤海底层温、盐度与其垂直平均值的统计关系

The Statistical Relation between the Bottom Temperature,Salinity and Their Vertical Average Values in the Huanghai and Bohai Seas

文中根据黄渤海区１９５９～１９８２年间水温和盐度垂向剖面历史资料，建立了在给定水深下底层温、盐度与其对应的垂向平均值间的线性关系，进而对所获得的系数建立其与水深和时间（月份）间非线性关系，最终发展了底层温、盐度与其平均值、水深和时间的普适经验关系式ＴＨ（Ｓｕ）＝ｆ（ＴＡ（ＳＡ），Ｈ，ｔ），为建立避开来自海面的热量、质量和动量在会向上分配的复杂物理过程的简易底层温、盐度二维数值预报模式奠定基础。

In this paper, based on the historical hydrosraphic data of the temperature and salinity in the Huanghai and Bobal Seas measured from ling to 1982, a linear Correlation between the bottom temperature and salinity and their corresponding vertical average values at a given depth are constructed. Furthermore, non-linear correlation between the obtained coefficientS and water depth and time(month) are then established. Finally, the commonly applicable empirical relation among bottom temperature and salinity, their average values and water depth and time is developed, respectively.This method lays a basis of a simple two dimensional numerical prediction model for the bottom temperature and salinity regardless of the transfer of heat, mass and momentum coming from sea surf see in the vertical direction.
