Some rain-gauges produce a disturbance of the air currents which is called "Jevons effect", thereby a disturbance in the distribution of precipitation of such a kind that a part of the rain is carried past the rain-gauge, and the amount of variation from the true rainfall increases with increasing wind velocity. To evaluate the capture ratio when a strong wind occurs, the 9 m2 huge rain-gauge was invented that could reduce and neglect the Jevons effect. The total amount of rainfall for three months observed from the huge rain-gauge is about 5 % greater than that observed from the standard rain-gauge. 2-dimensional video disdrometer analysis showed that the capture ratio was low during the rainfall which had the small median diameter of the raindrop size distribution.
