A Synthetic Analogue Model for Medium-range Forecasting by Man-machine Interaction

摘要: 该文采用人机交互方式制作中期预报综合相似模型。该模型在客观相似分析的基础上，引入主导环流系统（关键区）和环流演变场，以此来渗入预报员丰富的预报经验、降低相似环流变化的随机性，经业务应用结果表明在中期天气要素预报上取得较好的效果；同时模型具有广泛的适用性。

Abstract: The synthetic analogue model of medium-range forecast was made by means of man-machine interaction. Based on the objective similarity analysis, the prevailing circulation system (key regions) and the circulation evolution field were introduced into the model, so that the forecaster’s experiences were effectively applied and the randomness of similar circulation evolution was reduced. The better results of the operational application in medium-range weather element forecasting were obtained, and the model could be widely used.
