By the method similar to, but a little different from those proposed by Prof. T. Terada, gustiness of wind at three stations with different sea-levels, Hakoneyama (936.2m), Misima (20.1m) and Numadu (6.0m) were compared with the results:
(1) at each station the coefficient g in the equation v_m=gV+k:, where v_m is the mean maximum amplitude and v the mean wind velocity, is greater for easterly than for westerly wind, and their ratio is nearly the same at all the stations.
(2) g, for easterly and westerly wind directions are respectively 0.57, 0.42 on Hakoneyama, 1.26, 0.87 at Misima and 1.45, 1.09 at Numadu.
