本文回顾了两年来北京气象中心业务数值预报的进展.对效果有明显改进的几个方面作了详细叙述.统计检验结果表明短期数值预报业务有一定改进,但与世界先进国家预报水平相比仍存在相当的差距. |
英文摘要: |
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. |
