    Abstract
  • Variations of the Convective Boundary Layer (CBL) height and Entrainment Zone Thickness (EZT) have been studied based on 532-nm polarization lidar measurements between January 2011 and December 2017 at Wuhan (30.5°N, 114.4°E), China. The 1-min backscatter ratio R profiles are retrieved using the backward iteration Fernald method. The hourly CBL height and EZT are determined with the variance method. The results indicate that the CBL height and the EZT over Wuhan have obvious seasonal variation. The average value of the maximum CBL height is 1.14, 1.25, 1.06, and 0.74 km in spring, summer, autumn and winter respectively, while the average EZT is 0.4, 0.51, 0.34, and 0.26 km in spring, summer, autumn and winter respectively. These characteristics have a clear-cut positive correlation with the land surface temperature in Wuhan.
