中文摘要: 对欧洲中期预报中心1991年T106L19模式和1992—1993年T213)L31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。
中文关键词: 环流特征量，预报性能，统计检验
Abstract: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.
