The Numerical Study of Urban Atmospheric Boundary Layer
城市大气边界层的数值研究

Combining with the surface heat balance equation, a nonlinear and nonsteady two-dimensional numerical model, which is closed by energy method, is used to study the evolution of urban heat island and circulation as well as other parameters related to urban boundary layer. The transportation and dispersion of pollutant is also discussed in the case of urban pollutant area source. The simulation results are verified by the observation data on urban heat island in Tianjin.
