中文摘要: 在研究了冬季(11—1月)西北太平洋温带气旋爆发性发展前5天,对流层中高层超长波及长波配置及西风急流、动量输送等物理量特征的基础上,综合出气旋爆发性发展的中期预报着眼点,应用数值预报产品可有效地延长预报时效。
中文关键词: 超长波，急流，温带气旋，中期预报，爆发性发展
Abstract:Based on the analysis of the Features with the physical quantities of the relative parameters 5 days before the explosive development of the cyclones over the Northwest Pacific in winters during 1975-1988,it is found out that the locations of the explosive cyclones are related with the disposal of the ultra-long wave,long wave and the location of the westerly jet center in the middle-up troposphere. The studies lay a solid foundation to improve the medium-range forecasting. The forecasting rangs can be extented longer with NWP products.
