The assimilated result is quite same to the real vertical diffusivity coefficient , which suggests that the numerical model is feasible 我們選擇了不同的k _ v初值,結果是同化結果與真實結果相差很小,說明該模式是可用的。
A two layer numerical model is given which includes vertical integration equation , momentum equation , temperature equation , and its adjoint equations to study the vertical diffusivity coefficient 本文給出了一個二層數值模式,包括全流方程、運動方程和溫度方程,建立了一個伴隨同化模式來研究垂直混合系數。
The vertical diffusivity coefficients kv in january , april , july , october , 1997 are studied respectively . the result is same as the fact that the vertical diffusivity coefficient is large near the coastline and the vertical diffusivity coefficient is small in the interior . the vertical diffusivity coefficient assimilated in january is larger and the possible reason is that the vertical mixing of the south china sea is stronger in winter and there is a cool eddy in winter in the south china sea 我們分別做了1997年1 、 4 、 7 、 10月份的k _ v ,結果與垂直混合系數在岸邊附近較大,在海洋內部較小這一事實相一致, 1月份同化的垂直混合系數值偏大分析原因是冬季南中國海垂直混合較強,可能也與在南中國海內部冬季有一個冷渦有關系。
