A SENSITIVITY EXPERIMENT OF PRIMITIVEEQUATION MODEL WITH MIXED p-σCOORDINATES TO THE EXCHANGEBETWEEN LAND AND AIR

ZHAO Ming GAO Lei(Department of Atmospheric Science,Nanjing University,Nanjing,Jiangsu 210093)  
Abstract A sensitivity experiment of 5 and 9 layers primitive equation models with mixed p-σ coordinates in limited domain to the drag coefficient,which affects the flux exchange between land and air,is performed by use of a cold wave process as an example. The result shows that the model is sensitive to the value of the drag coefficient. The value of the drag coefficient over Qinghai-Xizang Plateau in original model is too small. Increasing the value of the coefficient over the Plateau can improve the predicted results of the model.
