On the Gustiness of Wind

[摘要] The period of the Gustiness was chiefly investigated and it was found that the longest period which was experienced when the velocity of wind was small reached 200 seconds or more, but when the velocity of wind exceeded over 10 metres the period became under 10 seconds and was nearly equal. The amplitude which was taken as the difference between the smallest and the largest values within 20 minutes was investigated and somewhat different from those generally treated. If Amax, is diffined as such a special meaning, or the amplitude of exteremity, it is expressed by the following relation, Amax=0.64X Wind VelocityThe relation can be held through the whole range of Wind Velocity.
