摘要
对欧洲中期预报中心１９９１年Ｔ１０６Ｌ１９模式和１９９２—１９９３年Ｔ（２１３）Ｌ（３１）模式６—８月４８—１４４小时５００ｈＰａ高度场预报和一些环流特征量进行了统计检验。结果表明，ＥＣＭＷＦ模式更新后夏季预报性能不稳定，亚洲地区更为突出；与原模式比较，一般西风带预报水平好于旧模式，而副热带预报水平不及旧模式。
The 500hpa height and circulation characteristic value of 48-144 hours forecasting byECMWF fO.r old model- T106L19 in 1991 and new model- T213L31 in 1991 - 1993 duringJune-August have been verified. The results show that after model renewal the prediction natures was instable in Summer,esl.pcially in Asia. The forecast made by the new model was generally better than the old model for the westerly belt .and was worse for the subtropical belt.
