Convective Boundary Layer and Entrainment Zone Thickness over Wuhan (30.5°N, 114.4°E) Observed by Lidar

  • 摘要: 基于地基偏振激光雷达2011年1月至2017年12月对武汉中心城区的观测资料,研究了超大城市对流边界层高度与夹卷层厚度的变化特征.采用Fernald方法进行数据反演获得了1min时间分辨率、30m空间分辨率的后散比剖面,通过方差法确定了对流边界层高度和夹卷层厚度.结果表明,武汉上空对流边界层高度和夹卷层厚度具有明显的季节变化特征.对流边界层顶的均值最大处在春季为1.14km,夏季为1.25km,秋季为1.06km,冬季为0.74km;夹卷层厚度均值最大处在春季为0.40km,夏季为0.51km,秋季为0.34km,冬季为0.26km.这些特征与武汉地区地表温度的周年变化特征具有很强的相关性.
