Based on GMS-5 infrared satellite images from 1996 to 1999, NECP data, the actual (typhoon) data from Typhoon Annual and GOES-9 infrared satellite images, an experiment was made on quantificational forecasting of the typhoon motion by stepwise analogy. The result experiment indicates that GOES-9 data is compatible with GMS-5 data and it can quantificationally forecast the typhoon motion by the method of analog forecasting with grey field and geopotential height field. The analog method does well in typhoon track forecasting, and therefore it would have a well application perspective.
