| Abstract: | An available approach for regional offshore wind resource assessment was presented by mesoscale modeling combined with history observations. The Fifth generation Mesoscale Model (MM5) was used to simulate wind field over the selected coastal and offshore areas in South China. This presentation mainly showed the influence on simulation results by assimilating hourly surface wind observations from coastal marine stations and the wind-retrieved data from the Sea Winds scatterometer on QuikSCAT satellite into the MM5 model. The wind simulation results were analyzed and compared with actual wind observations. Numerical results indicate that it is possible to improve wind analysis by assimilating actual observations with fine resolution in both space and time together with other types of data into the model. |
