Meridional Propagation of Planetary-Scale Waves in Vertical Shear: Implication for the Venus Atmosphere
Publisher: American Meteorological Society
Abstract: It is shown that planetary-scale waves are inherently accompanied by latitudinal momentum transport when they propagate vertically in vertically sheared zonal flows. Because of the dependence of the wave's latitudinal scale ...
Parameterization of Surface Brightness Temperature to Retrieve Trace Gases from Radiance Spectra Measured with a Nadir View
Publisher: American Meteorological Society
Abstract: Any inversion algorithm that ignores the wavenumber dependence of the surface emissivity could cause systematic errors in the retrieval of atmospheric trace gas concentrations from high-resolution nadir radiances. The error ...
Microphysics of Venusian Clouds in Rising Tropical Air
Publisher: American Meteorological Society
Abstract: As the global distribution of Venusian H2SO4?H2O clouds is strongly related to the global circulation of H2SO4 governed by wind transport and sedimentation of droplets, the circulation of H2SO4 in the Tropics was studied ...
Mesoscale Spectra of Mars’s Atmosphere Derived from MGS TES Infrared Radiances
Publisher: American Meteorological Society
Abstract: Wavenumber spectra of the atmospheric potential energy of Mars at mesoscales (wavelengths of 64?957 km) were obtained as a function of latitude, season, and Martian year using infrared radiance data obtained by the Thermal ...
Vertical Wavenumber Spectra of Gravity Waves in the Martian Atmosphere Obtained from Mars Global Surveyor Radio Occultation Data
Publisher: American Meteorological Society
Abstract: ertical wavenumber spectra of Martian gravity waves were obtained for the altitude range 3?32 km from temperature profiles acquired by the Mars Global Surveyor (MGS) radio occultation experiments. The spectra, which cover ...
The Lateral Transport of Zonal Momentum Due to Kelvin Waves in a Meridional Circulation
Publisher: American Meteorological Society
Abstract: A modified, equatorial Kelvin wave solution is obtained in the presence of the zonal-mean meridional circulation. The modified Kelvin wave solution, which is obtained via a perturbation expansion of the linearized, primitive ...
Vertical Wavenumber Spectra of Gravity Waves in the Venus Atmosphere Obtained from Venus Express Radio Occultation Data: Evidence for Saturation
Publisher: American Meteorological Society
Abstract: y using the vertical temperature profiles obtained by the radio occultation measurements on the European Space Agency (ESA)?s Venus Express, the vertical wavenumber spectra of small-scale temperature fluctuations that are ...
