A COMPUTATIONAL SCHEME OF HORIZONTAL PRESSURE GRADIENT IN OCEAN MODELS WITH σCOORDINATE SYSTEM

Qian Yongfu; Peter Chu; Wang Qianqian(Department of Atmospheric Sciences. Naming University, 210093. Naming. PRC )  
in the ocean circulation models with steep bottom topography the computation of the horizontalpressure gradient is a difficult problenl. Near the land shelf, the topography slope is very steep. and the topography changes rapidly. Errors in the computation of the horizontal pressure gradient often cause the computational instability or the unbelievable ocean currents. The USA Princeton University ocean Model(POM )adopts the a coordinate system as the vertical coordinate; this problem is specially severe and important. POMuses the hydrostatic reduction scheme to compute the horizontal pressure gradient which has quite high accuracy already. However. the authors find after analyzing the scheme that the computational method in POMcould be further improved. In this paper the authors developed a new scheme of computation of the horizontalpressure gradient in the a coordinate ocean models based on the principle of numerical computation scheme ofthe pressure gradient in the atmospheric models with large and steep topography and by taking account of theconcrete situation of the ocean, the detailed derivation is given. By the use of the POM. the new scheme istested and compared with the original one of the POM. The results show that the new scheme can efficientlyimprove the accuracy of the horizontal pressure gradient computation due to its evident physical meanings.
