COUPLING THREE DIMENSIONAL BAROCLINIC MODEL OF BIWA LAKE AIR-WATER SYSTEM |
| |
| Abstract: | A numerical model coupling atmosphere with hydrodynamics is set up in this paper, and is applied in the experimental study of Lake Biwa. Some results are obtained as : (1) whatever (SSW) in sunimer or (NNW) in winer, there exists a positive wind-stress curl over a lake; (2) in summer the positive wind-stress curi plays an important role to form circulation in a lake and produces a special temperature field corresponding to circulation, lower in the deep water, higher in the shallow water; (3) in summer, the hypothesis of initial horizontal inhomogeneous water temperature has little effiect on the results of simulation, and (4) in winter,there is no obvious circulation formed in the lake. |
