This paper analyzed recurvature of typhoons by using 20 years meteorological data from 1992 to 2011. The results of this study are as follows. Yearly numbers of typhoon recurvature showed decreasing tendency gradually with decrease of numbers of typhoon occurrence. Typhoons recurvature were especially many between August and October and number of typhoon recurvature between July and October was occupied counts for 71 % of the whole typhoon recurvature. Life of typhoon recurvature in the North Pacific was most frequent at 5 days and 7 days. Mean life of typhoon recurvature was 6.8 days and this numerical value was longer than mean life of the whole typhoon including recuevatute and non-recurvature. Most of typhoons recurvature changed their direction north-eastwards in 20-34 degrees north latitude and 120-139 degrees east longitude. Mean latitude recurvature and longitude recurvature were 25 degrees north latitude and 135 degrees east longitude, respectively.
