内容 研究概要:Boundary layer has a diurnal variation of temperature near the ground with thickness variation ranging from hundreds of meters to a few kilometers. The dynamics of this layer can reveal the trapped pollutants related to atmosphere, climate, and human activities in urban areas of a city. In this paper, we present the first time a comprehensive result of tracking urban planetary boundary layer of Hong Kong (22.3N, 114.7E). The daily and seasonal variations of the mixing depth in the planetary layer over urban areas in Kowloon have been investigated using a ground-base Lidar station situated in the City University of Hong Kong to monitor relative aerosol concentration. The relationships between the aerosol profile, which is used to estimate the depth of the mixing layer, and the virtual potential temperature as well as relative humidity are examined. The Lidar observations and the radiosonde data obtained from the local meteorological station are in close agreement.
