| Abstract: | Results of large-eddy simulations of shallow, quasi-steady, shear-less convection in the Martian boundary layer are presented
and discussed. In the considered three cases, turbulence is forced by the radiative flux divergence, prescribed as given functions
of height, and the strength of the surface heat flux. It is constrained by the temperature inversion at the boundary-layer
top. The resulting convective boundary layer exhibits horizontal cellular structures. The presence of radiative heating causes
dimensionless statistics of turbulence to depend on the parameter F, defined in terms of the integrated radiative and turbulent heating rates in the boundary layer. |
