2016. 9. 30STATISTICAL ANALYSIS OF TYPHOON RELATED EVENTS IN HOKKAIDOAND SURROUNDINGS IN THE LAST 56 YEARSINCLUDING THE 2016 HEAVY RAINFALL
Yoshikazu KITANO, Taro YAMAMOTO, Ayaka KOBAYASHIand Tomohito J. YAMADA
In August 2016, heavy rainfall induced by typhoons struck various part of the Hokkaido and Tohoku
regions, northern part of Japan, causing severe floodings and sediment disasters. These typhoons headed
northward along the coast of Japan facing Pacific Ocean and reached Hokkaido and its surroundings. In
this study, we categorize the route of typhoons that reached Hokkaido by the Sea of Japan, Japan Islands
and the Pacific routes for the 56-year period. The results show that Pacific route is dominant in August
2016 and they occured with extension of the Pacific anticyclone towards Northern part of Japan.
