Study on the mixed layer, entrainment zone, and cloud feedback based on lidar exploration of Nanjing city

[1] An experiment devoted to the lidar (LIght Detection And Ranging) study of the urban boundary layer (UBL) over Nanjing city was executed from February 20 to March 5, 2006. Many other techniques including radiosonde, meteorological towers, and turbulence measurements were also performed in order to explore the UBL. In this paper, the results of the lidar experiment with other observation data are presented. The experimental results demonstrate the daily transition features of the mixed layer (ML) and the entrainment zone (EZ). The different features of the ML between urban and suburban areas have been revealed by comparison. Furthermore, cloud feedback on the mixed layer depth (MLD) and the entrainment zone thickness (EZT) has been analyzed.
