Abstract

Based on the observing data from island station,the characteristics of wind speed in Lian Yun-gang were analyzed and the sub-regions of wind prediction were set up.The result of WRF model showed that the model could resolve the variation trend of wind,speed,but the deviation of the wind speed was high.The results also showed that the model forecasting performance of wind speed was lower for the special geographical region.After the adjustment with the Kalman filter method,the forecasting accuracy of wind speed was improved for the island station and all the other sub-regions.
