The invention provides a method for forecasting landed typhoon characterization factors based on historical data. The method includes the following steps: conducting landing judgment on typhoons in a delimited area according to the typhoon landing judgment criteria; obtaining a plurality of predictors if the typhoon landing probability is larger than a preset threshold value; building a forecasting equation according to the multiple predictors, wherein the forecasting equation is built according to the historical data; determining a forecasting mode and obtaining corresponding observation point information; conducting forecasting according to the corresponding observation point information, the forecasting mode and the forecasting equation. By means of the method, reliable forecasting can be carried out on the typhoon characterization factors; in addition, the method is high in accuracy, good in portability, high in targeting performance and good in instantaneity. The invention further provides a system for forecasting the landed typhoon characterization factors based on the historical data.
