In this paper, the yearly tropical cyclone potential impact index (YTCPI) is used as the link to preliminarily study the method of typhoon preevaluation for annual disaster situation in China. The results of preevaluation test show that, from 1991 to 2008, the preevaluation of typhoon disaster for 1996, 1997 and 2004 was lower than the facts, and for other years matched with the actual situation well. The test results of independent samples in 2009-2013 show that, only in 2009 the preevaluation was not correct. In general, it’s feasible to preevaluate the annual disaster situation of typhoon with YTCPI index.
