The wind energy, clean, renewable, and abundant in nature, offers pollution-free electricity, as the fastest growing energy approach in the world. Studies on wind climate and the change of wind resources are widely carried out. The observations of wind speeds during the 20th century indicate that: ① the wind speed sees an increasing trend in high latitudes and a declining trend in low latitudes of both hemispheres; ② the annual mean wind speed sees an obviously declining trend over broad areas of China; ③ urbanization, the change of anemometers, or the relocation of stations in China are factors that might be responsible for the decreasing trend of mean wind speeds. The decreasing trend in China is mainly due to the changes of atmospheric circulation. Furthermore, the prediction of wind and wind energy in the 21st century shows that as a result of increasing anthropogenic emissions and global warming, the annual and winter mean wind speeds and wind power densities are likely to reduce. The changes of summer mean wind speeds and wind power densities see great uncertainties. At present, the studies on the prediction of surface wind speed by the climate models and simulations have just started, and much work has to be done before some relatively reliable conclusions might be reached., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=9ue7ANVY/dX+i9yJgxorWQ==, pdfFileSize=1068727, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, fund=null), CN=ArticleExt(id=1242116944116125744, articleId=1242116941301747745, tenantId=1146029695717560320, journalId=1146031591421210625, language=CN, title=中国及世界风资源变化研究进展, columnId=1242116809164390686, journalTitle=科技导报, columnName=综述文章, runingTitle=null, highlight=null, articleAbstract=20世纪以来，随着能源需求成倍增长，风能资源因其安全、清洁、丰富的特性已成为世界上增长最快的能源方式。有关风能资源可持续利用的近地层风和风能资源变化研究也逐渐开展起来。20世纪观测事实研究表明，① 全球高纬度地区风速呈增大趋势，而中低纬度地区风速呈减小趋势变化；② 中国近50年来年平均风速呈明显的减小趋势变化；③ 中国区域城市化发展、测站迁址及测风仪器的变更都对中国年平均风速的长期变化产生了一定影响，但都不是近50年来中国年平均风速呈显著减小趋势的主因；大气环流的变化才是造成中国年平均风速呈显著减小趋势的最可能原因。与风和风能资源预估相关的研究表明，21 世纪由于人为温室气体排放增加和全球变暖，中国年平均和冬季平均风速和风功率密度将可能减小，夏季平均风速和风功率密度的变化不确定性较大。目前，利用气候模式模拟和预估近地层风速方面的研究才刚刚开始，今后还需要做大量和长时间的研究试验，才能得到更可靠的结论。, authors=江滢¹,罗勇¹,赵宗慈¹,ZHU Jinhong², authorsList=江滢;罗勇;赵宗慈;ZHU Jinhong, authorCompany=1. 中国气象局国家气候中心2.
