Wind simulation using different parameters in a weather research and forecasting model

Abstract

A study designed different parameter schemes for a weather research and forecasting model to simulate hourly winter and summer wind speed and direction at a wind-farm tower in China. The schemes were found to reproduce the local wind conditions accurately and simulate wind direction very well. The results showed that one scheme performed better for the wind speed and wind direction simulation at 10 and 90 m height in the winter, while another performed better for simulation at 10 m height in the summer. The results for these schemes showed that the correlation coefficients of wind speed and wind direction were 0.75 and 0.62 in winter and 0.55 and 0.44 in summer, respectively. Overall, the parameterised model exhibited better simulation of the wind speed than wind direction, and was better in winter than in summer.
