抄録

At the midnight of September 16, 1978, a small tornado or Tatsumaki hitted Shionomisakiat the southern end of the Main Island of Japan and caused some damages. The damageswere distributed in a narrow belt extending from SSW to NNE. The length of the damagedarea was 1.6km and the width was 150m at maximum. The wind direction associated withthe Tatsumaki was able to be presumed from the diretion of blown roof tiles, and therotating wind system was found. The distributions of pressure fall and wind speed in theTatsumaki were estimated from the meteorological records obtained at some observatoriesalong the path. The peak gust is evaluated to be about 42m/s from the meteorological analysisand also to be more than 40m/s from the damages. The damages caused by the Tatsuinakiat Tanabe near Shionomisaki in the same month are also discussed.
