摘要:

风能资源作为一种无污染可再生能源,在能源结构多元化发展中具有很大的发展潜力。利用定陶1981~2015年35年国家气象观测站气象观测资料,统计分析定陶风气象要素气候变化特征,结果表明:定陶近35年年平均风速呈微弱增加趋势,气候变化倾向率为0.057 m/s/10a。春季最大,秋季最小;4月份最大,9月份最小;风速日变化明显。年平均最大风速呈减小趋势,气候变化倾向率为0.365 m/s/10a,年平均大风日数呈明显减少趋势,气候变化倾向率为−0.843d/10a。大风日数最多的是春季,最少的是冬季。以偏南风和偏北风为主(除静风外),春、夏季以偏南风为主,冬季以偏北风为主。

Wind energy resource, as a pollution-free renewable energy in the development of diversified energy structure, has great development potential. The climatic variation characteristics of Dingtao wind speed were analyzed by using the Dingtao 35 years from 1981 to 2015 in the national metrological observation data. The results showed that the Digntao 35 years had week increase in average wind speed, and the climate change trend rate is 0.057 m/s/10a with maximum in Spring and minimum in Autumn, maximum in April and minimun in September. The annual average maximum wind speed showed a decreasing trend; the climate change tendency rate was 0.365 m/s/10a; the average annual gale days were significantly reduced; the climate change tendency rate was −0.843 d/10a. The most strong wind days is in Spring, and least in Winter, which mainly focus on southerly winds and northerly winds (except no wind), with southerly winds in spring and summer, northerly winds in winter.Wind energy resource, as a pollution-free renewable energy in the development of diversified energy structure, has great development potential.
