Abstract: 台風7220は1972年9月16目夕方, 和歌山県串本町潮岬西方に上陸し, 紀伊半島を通り抜けた。この時, 潮岬においては, はっきりした台風眼通過現象が見られた。この際, 京大防災研究所潮岬風力実験所で台風眼通過時前後の風速の早送り記録を得ることができたので, これを解析し, 台風中心附近の風の特性を調べてみた。この解析においては台風のeyewaHの近くの最大風速域の通過前後の強風の盤質と共に従来調べられたことのない台風眼内の風の性質についても調べることができた。
Characteristics of wind speed fluctuation of Typhoon 7220 were analyzed using the windspeed records at Shionomisaki where the typhoon eye passed. Characteristics of wind turbulenceat high wind speed before and after the pass of the typhoon eye resemble each other and spectralpeak is found at about 300 m in the wave length. Near the center of the typhoon eye, wind speedis as low as 10 m/s. However the intensity of turbulence and spectral peak wave length are almostthe same as those in the high wind cases.
