中文摘要: 将集对分析中的联系度概念用于云南省强降水过程预报集成,首先对强降水天气过程进行分型,确定MM5模式预报、省台客观指导预报、预报员经验预报与云南强降水过程的联系度,用权重法将强降水预报进行集成,从而给出集不同预报于一体的云南全省性强降水过程预报集成方法。
Abstract:The concept of contact degree in Set Pair analysis is applied to heavy precipitation processes forecast ensemble in Yunnan Province. First,the heavy precipitation processes is defined into different patterns. Contact degree among severe precipitation processes and forecast of MM5 meso scale model or objective forecast of Yunnan Province or empirical forecast of forecaster are confirmed. The weighting method is used to integrate with severe precipitation processes forecast. Finally,the severe precipitation processes forecast ensemble method is given.
