摘　　要：利用1991—2020年ERA5 100 m风速和地面太阳辐射及Beluco-CIWS互补指数,对湖北省风光资源要素日变化互补特性开展分析。结果表明:(1)湖北中东部互补性较强,西部互补性较差。海拔越高,互补性越弱,海拔越低,互补性越强。秋季互补性较强,冬季次之,夏季最弱。风速大的地区互补性强,风速小的地区互补性弱。(2)互补性强的区域风速呈现先减后增、白天风速小、夜间风速大的日变化特征,互补性弱的区域日变化特征相反,互补性强弱取决于风速强弱及日变化特征是否异常。Using the 100 m wind speed and surface solar radiation data of ERA5 from 1991 to 2020,the complementary characteristics of diurnal changes in wind and solar resource elements in Hubei Province were analyzed based on the Beluco-CIWS complementarity index.The results show that:(1)the central and eastern parts of Hubei province have more strong complementarity,while the western part has poor complementarity;the higher the altitude,the weaker the complementarity,and the lower the altitude,the stronger the complementarity;the complementarity is stronger in autumn,followed by winter,and the weakest in summer;areas with higher wind speeds have strong complementarity,while areas with low wind speeds have weak complementarity;(2)the wind speeds in areas with strong complementarity show the characteristics of diurnal changes of decreasing and then increasing,with small wind speeds during the day and large wind speeds at night,and the opposite is true for the region with weak complementarity;the strength of complementarity depends on the strength of the wind speed and whether the diurnal variation characteristics are abnormal or not.
