A weighted 3-level steering scheme of typhoon forecasting

As a promotion study of the previous 2-level steering model, a weighted 3-level steering typhoon forecasting scheme has been developed and put into operation at the Kuangzhou Forecasting Center in the typhoon season of 1987. A verifi-cation of forecasts shows that the averaged typhoon position error produced by the scheme is less than that issued correspondingly by the JTWC at Guam and also less than the mean error produced by the 2-level steering model which has worked for many years.
