Characteristics of Wind Velocity Fluctuation Observed in a Coastal Field Facing The Japan Sea

Abstract

The spatial correlation of wind velocities and temporal fluctuations were investigated based on the wind data observed at 26 weather stations installed on the Shonai plain. It is found out that the coefficient of correlation between wind velocities at two stations including inland station is the smaller than that of the other two stations. As for the temporal wind fluctuations,the frequency of large increment of wind velocities was almost the same as that of downslope winds observed in the mountain area.
