利用NCEP/NCAR再分析资料对江西省金华山测风塔数据进行订正，计算平均风速、风速频率、风向频率、各方向风能、风功率密度及有效风能时数等各项风能参数。结果表明，风电场各个高度年平均风速为5.7—6.7 m/s，年平均风功率密度为214—366 W/m2，年有效风力时数百分率为76.3%—82.2%；风向和风能频率集中风向为SW—WSW风，有利于风机的布局和稳定运行，具备开发潜力。
利用NCEP/NCAR再分析資料對江西省金華山測風塔數據進行訂正，計算平均風速、風速頻率、風嚮頻率、各方嚮風能、風功率密度及有效風能時數等各項風能參數。結果錶明，風電場各箇高度年平均風速為5.7—6.7 m/s，年平均風功率密度為214—366 W/m2，年有效風力時數百分率為76.3%—82.2%；風嚮和風能頻率集中風嚮為SW—WSW風，有利于風機的佈跼和穩定運行，具備開髮潛力。

By using NCEP/NCAR Reanalysis data, the data from Jinhua Mountain wind towers were revised to calculate the average wind speed, the wind speed and direction frequencies, the wind energy in all directions, the wind power density and effective wind energy hours. The results showed that the average annual wind speeds at all height were 5.7-6.7 m/s , the annual average wind power density was 214-366 W/m2, and the percentage of annual effective wind energy hours was 76.3%-82.2%. Most of the wind directions for the frequencies of wind direction and wind energy were the SW—WSW, which meant that this region was conducive to the stable operation of the wind turbine.
