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

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.
