โฆ Synopsis
The contribution of radiative and turbulent processes to nocturnal atmospheric cooling has been studied using the experimental data of the ECLATS experiment which took place in the African Sahel; the radiative and turbulent fluxes were determined taking thermal advection into account. The turbulent cooling rate is predominant; it decreases strongly with altitude at the beginning ofthe night, which is the main cause of inversion formation.
