吉阳核电厂址近地面层温度梯度及风廓线规律适用性研究

观测安徽吉阳核电厂址近地面层的气象数据,对该厂址近地面层温度梯度及风廓线规律的适用性进行了分析,通过散点图的形式寻找风速比随稳定度参数的变化特征。结果表明,本区气温日变化符合一般观测规律,四季平均气温有较大差异、温差偏大,春夏两季多易出现逆温,春冬逆温强度较夏季偏大;非中性层结条件下风速比值随稳定度的增强而离散增大。

Analysis on Temperature Gradient and Applicability of the Wind Profile Law with the Near-Surface Layer of Jiyang Nuclear Power Plant

Based on the observation data from the near-surface layer of Jiyang Nuclear Power Plant in Anhui,the temperature gradient and the applicability of the wind profile law is analysed,and the features of the wind speed ratio by the changes of the stability parameter are found by the scatter.Results show that the daily temperature changes in this area are in line with the general observation rules,and the average temperature of the four seasons is quite different,temperature difference is large,and the inversion appears easily in the spring and summer,and the temperature inversion in the spring and winter is larger than that in summer;the wind speed ratio is increased with the enhanced stability under the conditions of non-neutral stratification.
