A simulation of turbulent transport during 24-hour evolution of the atmospheric boundary layer

This paper aims to select an accurate and numerically efficient second-order closure model of turbulence to predict dispersion of pollution in the atmospheric boundary layer. An one-equation E-model suggested by Mellor and Yamada, two-equation E-epsilon model by Duynkerke and E-l model with algebraic relations for Reynolds stresses and turbulent fluxes for conditions of 33-34 days of the Wangara experiment are compared. Ii is shown that the later model more accurately predicts data of observation but it needs more computational time.
