STUDY OF RADIATIVE AND TURBULENT PROCESSES IN THE STABLE BOUNDARY-LAYER UNDER WEAK WIND CONDITIONS

The role of radiation and turbulence was studied in a weak wind noctur nal inversion layer using a one-dimensional model. In contrast to a st rong wind stable boundary layer where cooling within the surface inver sion layer is dominated by turbulence, radiative cooling becomes large r than turbulent cooling under weak wind conditions. Further. the surf ace inversion layer was found to grew all through the night under weak wind conditions. whereas it attained a near equilibrium in the case o f strong wind.
