(3) Typhoons Low pressure systems that occur in tropical regions are called tropical cyclones, and among them, those with a maximum wind speed of 17 m/s or more within their area are called typhoons. As shown in Figure 14, the wind speed distribution within a typhoon area can be thought of as a Rankine compound vortex with V / R = constant ( V is the wind speed, R is the distance from the center) near the center of the typhoon and VR = constant outside of that area. ...

…この経験則は考案者の名をとってボイス･バロットの法則として知られている。(3)台風　熱帯地方で発生する低気圧を熱帯低気圧tropical cycloneというが，このうちで域内の最大風速が17m/s以上のものを台風と呼んでいる。台風域内の風速分布は図14に示すように，台風の中心付近でV/R＝一定(Vは風速，Rは中心からの距離)，その外域でVR＝一定のランキンの複合渦となっていると考えてよいであろう。…
