The main purpose of this paper was to present a new method for interpretation of the products of ECMWF Ensemble Prediction System(EPS). The basic assumption was that the EPS members represent, in a certain degree, the future weather situations. In order to resolve the problem that the synoptic scales are not predictable in the medium range, the conception of weather type was introduced. The approach for automatic classification was Dynamic Fuzzy proposed by Diday, and a new distance called Displacement and Maximum...

The main purpose of this paper was to present a new method for interpretation of the products of ECMWF Ensemble Prediction System(EPS). The basic assumption was that the EPS members represent, in a certain degree, the future weather situations. In order to resolve the problem that the synoptic scales are not predictable in the medium range, the conception of weather type was introduced. The approach for automatic classification was Dynamic Fuzzy proposed by Diday, and a new distance called Displacement and Maximum Correlation was adapted. During the iteration, the initial gravity was defined by the weather types. In China, the weather types in summer and winter were determined by the automatic classification. The premier applications showed that EPS may predict the atmospheric evolution in winter, but the predictability in summer was relatively poor.

该研究的主要目的是找出一种对集合预报产品进行释用的新方法。其基本假定是集合预报要素在一定程度上代表了未来可能发生的天气形势。为了解决天气尺度在中期预报的不可预报性问题 ,引入了天气类型的概念。对集合预报进行划分的方法是 Diday提出的动力模糊法 ,初始划分时的重心由天气类型定义 ,划分用到的距离是位移和最大相关方法。根据城市块 (City- Block)距离找出了影响中国的按冬夏两季划分的天气类型 ,初步划分结果表明 ,欧洲中期天气预报中心的集合预报系统可以预报出横槽转竖型天气类型的演变情况 ,在夏天的预报效果则没有冬天好。

The Ensemble Prediction System (EPS) in principle can be called the Probabilistic Prediction System (PPS) of which its ultimate goal is to provide the full probabilistic forecast for all variables. Compared to the beginning of EPS era in 1992 that just considered the uncertainties existed in the initial conditions, one of the most significant progresses made on ensemble techniques during the past few years, is that the model uncertainties have been taken into account, and then is the development of the multi model and multi analysis ensembles.Some problems existed in the operational EPS such as the generation of initial perturbations, multi model ensembles, the application of ensemble products and its verifications are described, and the outlook of this perspective technique is exhibited.

集合预报系统从原理上讲也可称之为概率预报系统 ,其最终目的是要提供所有大气变量的完全概率预报。近几年集合预报技术已从以前仅考虑初值的不确定性发展为也考虑模式的不确定性 ,进而发展了多模式 -多分析集合预报技术等。阐述了目前业务集合预报的一些问题 ,如扰动初值的生成、多模式集合预报、集合预报产品的应用、检验评价等 ,介绍了近几年集合预报的新的进展及该技术的未来发展趋势。
