Radiative effects of upper tropospheric clouds observed by Aura MLS and CloudSat

[1] The radiative effects of upper tropospheric (UT) clouds observed by CloudSat and Aura MLS during June-JulyAugust 2008 are examined and contrasted. We find that the UT cloud occurrence frequency observed by MLS is more than CloudSat by 4–10% in the tropical average and by 40 60% near the tropopause in the deep convective regions. The clouds detected by MLS but missed by CloudSat (denoted as ...

Parametrization of momentum and energy depositions from gravity waves generated by tropospheric hydrodynamic sources

The mechanism of generation of internal gravity waves (IGW) by mesoscale turbulence in the troposphere is considered. The equations that describe the generation of waves by hydrodynamic sources of momentum, heat and mass are derived. Calculations of amplitudes, wave energy ̄uxes, turbulent viscosities, and accelerations of the mean ̄ow caused by IGWs generated in the troposphere are made. A com...
