Abstract
A strong wind disaster was caused by Typhoon 9119 in the Tohoku district
on September 28, 199l. The purpose of this report is to investigate the
relationship between the surface wind field and the localization phenomena
of severe forest damage by the typhoon in Akita Prefecture. The results
are summarized as follows.
l) The strong wind of about 20 m/s in mean wind speed prevailed for about
three hours in the restricted region of the northern inland part in Akita
Prefecture.
2) This restricted region was coincident with the towns and villages
suffered the severe forest damage.
3) The facts mentioned above suggest that Typhoon 9119 possessed the
unique structure in the dissipating stage.
