中文摘要: 针对“5·5"特大沙尘暴致灾天气过程,综合检验分析我国T42、有限区(LAFS)和欧洲中期数值预报中心(ECMWF)数值预报模式的性能及其产品的预报能力。结果表明,各家数值预报模式对该过程的500hPa形势预报是成功的,可为中、短期预报提供预报决策信息。T42和LAFS对中、高层西风的预报质量较高,亦有预报参考意义,其它的物理参数的预报质量有待进一步改进优化。
中文关键词: 特大沙暴，数值产品，释用分析
Abstract:Analysis of the performance of T42 LAFS and ECMWF NWP models and efficiency of their products.suggests that the 500hPa pattern prodictions of all kinds of the models are successful.The informations can be refered to the medium-range and short-range forecasting decision. The wind predictions of T42 and LAFS model are of higher quality. The prediction quality of the other physical parameters should be made better and improved in the future.
