Abstract

This research aims at improving a WRF-simulated vertical profile of land breezes. Surface and Doppler LIDAR measurements from Hazaki, Japan are used to evaluate the accuracy of the simulated wind speeds, obtained by changing turbulence schemes, the numbers of vertical layers, the heights of upper boundary, and parameters expressing a vertical profile. Three conclusions obtained here are: 1) Wind speed difference performs better than wind speed ratio in estimating hub-height wind speed from surface wind speed, 2) a RANS model leads to better accuracy than WRF-LES, and 3) Increasing the number of vertical layers in the surface to 500 hPa range is more effective than heightening the upper boundary to 100 hPa.
