The stratified wind tunnel in which the density of air gradually changes with height is available for experimental studies on thermal convective air currents under the developed thermal inversion layer. The convective currents do not thrust through the upper light layer, but spread out horizontally, and the circulation pattern is similar to that of the so-called heat island obtained by numerical simulation. It suggests the mechanism of the local flow patterns of urban heated and urban polluted air.
