Annual average monthly wind speed in Heihe river basin (1961-2010)

The station data information of 21 regular meteorological observation stations in Heihe River Basin and surrounding areas and 13 national benchmark stations around Heihe River provided by Heihe plan data management center are used to make statistics and collation of daily wind speed and calculate the monthly wind speed data of 1961-2010 for many years. The spatial stability analysis is carried out to calculate the variation coefficient. If the variation coefficient is greater than 100%, the geographical weighted regression is used to calculate the relationship between the station and the geographical terrain factors, and the monthly wind speed distribution trend is obtained; if the variation coefficient is less than or equal to 100%, the common least square regression is used to calculate the relationship between the station wind speed value and the geographical terrain factors (longitude and latitude, elevation, slope, aspect, etc.) The trend of monthly wind speed distribution is obtained, and the residual after removing the trend is fitted and corrected by HASM (high accuracy surface modeling method). Finally, the monthly average wind speed distribution of the Heihe River Basin in 1961-2010 is obtained by adding the trend surface results and the residual correction results. Time resolution: monthly average wind speed for many years from 1961 to 2010. Spatial resolution: 500M.

本数据集汇集了黑河流域及其周边地区21个常规气象观测站以及黑河流域周边13个国家基准站的站数据信息，由黑河计划数据中心提供。数据集通过对每日风速进行统计和汇编，计算了1961年至2010年多年的月风速数据。执行空间稳定性分析，以计算变异系数。若变异系数超过100%，则采用地理加权回归法计算站点与地理地形因素之间的关系，从而获得月风速分布趋势；若变异系数不超过100%，则采用普通最小二乘回归法计算站点风速值与地理地形因素（经纬度、海拔、坡度、方位等）之间的关系，获得月风速分布趋势，并对去除趋势后的残差进行HASM（高精度表面建模法）拟合和校正。最终，通过叠加趋势面结果和残差校正结果，获得了1961年至2010年黑河流域的月平均风速分布。时间分辨率：1961年至2010年多年的月平均风速。空间分辨率：500M。
