Abstract

Variation of tropical cyclone (TC) landfall results from the comprehensive effect of various physical factors including celestial activities, atmospheric circulation and influences from underlying surfaces. In this study, the previous predictors are used to conduct calculation, thus enabling the extension analysis to have prediction function. Through repeated adjustment of the grade limit value (classical domain and joint domain) of the factors, the historical fitting value of the calculation number of TC landfall incidences with the actual number can be made to reach the maximum value with good results. It has practical significance to typhoon prevention and disaster relief in coastal areas. Results indicate that using extension analysis to predict TC landfall incidences is an effective method.
