After the sunset, under calm and clear sky conditions, aerosol laden surfaceair-layer, cools radiatively to the upper atmosphere. Predominant effect of theradiative cooling on the vertical temperature profile extends to severalhundred meters from the surface. This results in the development of a stable,nocturnal inversion layer. However, ground surface, owing to its higher thermalinertia, lags in the cooling process. Due to this about a meter thick air layerjust above the ground can be (2-6)deg Celsius cooler than the ground. Thus, atthe surface an unstable convective layer is present, which is capped by astable inversion layer that extends up to several hundred meters. Thisconfiguration involving a convective mixed layer topped by a stably stratifiedinversion layer is a classic case of penetrative convection.Micrometeorological phenomenon at the surface, such as occurrence of fog, isdetermined by temperature profile, heat and moisture transport from the ground.Here, we present a computational study of the model penetrative convection,formed due to radiative cooling, in the nocturnal atmospheric boundary layer.
