| Abstract: | Since 1982,several modifications in the models used in operation have been made, such as the adoption of the lateral boundary condition formulated by Hovermale and Shuman's economical time differencing scheme in the 5-level Northern Hemispheric Model, and the replacement of the convective adjustment by the Kuo's cumulus parameterization scheme(1974) in the 5-level FLM. Owing to these modifications, both the objective and subjective verification of predictions showed that accuracy of operational NWP has been significantly improved. Finally, the application of NWP products is also summaried and a prospect for the futu:e is given. |
