Fine MOS Temperature Forecast Based on MM5;

By means of MM5 model and the third generation of shallow-water wave model SWAN.

By means of the hour-to-hour MM5-predicted basic element fields and physical-quantity diagnostic fields,as well as the recording humidity data of 25 stations over Ningxia Autonomous Region from May to September 2003,predictions are made of the 48-hour hour-to-hour relative humidity of 25 stations in Ningxia from May to September using the multiple linear and successive regression MOS methods.

Numerical Simulation of Different Convection Parameterization Schemes in MM5 Model;

MM5 model is the most popular mesoscale model in the world.

Numerical experiments on four cumulus parameterization schemes(CPSs) are carried out using the data of a Meiyu heavy rainstorm event occurred over the Changjiang basin in July 2002 with MM5 model.

In this paper, the MM5 adjoint-model that is based on variational method with adjoint codes technique as the core is introduced, on the basis of which, conventional observation data and unconventional observation data is applied into this Assimilation System for the purpose of assimilation research.
