Abstract: A quantitative study of the photochemistry of NH3 above the Jovian tropopause is given. The NH3, density distribution is described by two relevant vertical scales: Hav the scale height of the background atmosphere, and ...

Abstract: A detailed quantitative study of the photochemistry of CH4, C2H2, C2H4 and C2H6 which includes eddy and molecular diffusion is presented for the Jovian upper atmosphere composed of 90% H2, 10% He with a CH4 mixing ratio ...

Abstract: Radiative damping rates of atmospheric temperature perturbations can be calculated by either an eigenvalue method or a scale-dependent Newtonian cooling method, which we show are equivalent in two limits. One limit is an ...

Abstract: The problem of nonlinear saturation of baroclinic waves in two-layer models is studied and it is shown that Shepherd's rigorous bound on the wavy disturbance growth due to instabilities of parallel shear flow can be improved ...

Abstract: A mechanistic, quasi-geostrophic, semi-spectral model with a self-consistent calculation of the mean zonal flow fields is used to numerically simulate sudden stratospheric warmings generated by a single zonal harmonic (m) ...

Abstract: A theoretical study is made to assess the importance of the solar EUV flux in the thermal energy balance of the Jovian thermosphere. A global averaged vertical temperature contrast in the thermosphere of 15K is calculated ...

Abstract: The agronomy of hydrogen and its compounds is discussed in a simplified model intended to represent a diurnal and global average. Vertical transport by eddy and molecular diffusion is included for the major components H2O, ...

Abstract: The steady-state, zonally averaged circulation of the middle atmosphere (15?125 km) is studied with a quasigeostrophic, numerical model that explicitly includes a self-consistent calculation of solar radiative heating due ...

Abstract: The effects of various ozone density reductions on the zonally averaged circulation are evaluated with a numerical quasi-geostrophic model. If the ozone perturbation are confined to the polar regions and are minuscule on ...
