IMPROVING EXPERIMENTS OF A THREE-LEVEL PRIMITIVE EQUATION MODEL

Ji Li-ren Xing Eu-nan Chen Xiong-shan (Institute of Atmospheric Physics, Academia Sinica)  
Some improving experiments for solving the problems arised in the operational forecasts with the three-level primitive equation model are carried out. A series of tests are performed on a fourth order space difference scheme, reducing grid distance and improving initial winds.The improvement in the forecast of displacement of weather systems is obvious-The prediction of the development of weather system is also improved. The experiments also show that the initial winds and subsequent forecasts are sensitive to the value of Coriolis parameter, especilly at low latitudes.
