A Method for Medium-range Forecasting of Heavy Rain in Mei-yu Period

The method of multiplayer recursion is a new numerical forecast method using the theoretics of system identification in modern cybernetics. The harmonic analysis can reveal the characteristics of wave motion in various scales at different latitudes. In this paper, we have used the combination method to forecast medium-range heavy rain in Mei-yu period. The results show that the multiplayer recursion forecast model with increasing memory in the best one.
