Abstract: Possible thermally driven symmetric circulations of the mesosphere and upper stratosphere are considered, subject to the following major assumptions: the motions are in hydrostatic and geostrophic balance; the motions are ...

Abstract: Results of joint photochemical-radiative equilibrium calculations for the mesosphere and upper stratosphere are presented. The major assumptions were that only oxygen allotropes participate in the chemistry and that the ...

Abstract: The first four diurnal surface pressure harmonics have been analysed over major portions of two Martian annual cycles (Mars years) at the two Viking lander sites. The diurnal harmonies of surface wind have also been analysed ...

Abstract: The Mintz-Arakawa two-level model for planetary atmospheres has been adapted to simulate the atmospheric circulation and climate of Mars. The model uses the primitive equations of atmospheric motion, with heating and cooling ...

Abstract: Over 3000 Mariner 9 television reflectance profiles crossing the limb of Mars were analyzed statistically during the period from the decaying phase of a global dust storm (southern summer) until southern winter solstice. ...

Abstract: As a contribution to understanding the possible impact of altered climate regimes on marine clouds, and hence on cloud radiative forcing, ship-observed marine low clouds and precipitation frequency for individual seasons ...

Abstract: The behavior of Kelvin waves in the equatorial middle atmosphere is investigated with the use of daily mapped temperature derived from the Limb Infrared Monitor of the Stratosphere (LIMS) experiment. Diagrams of wave ...

Abstract: Observations of surface pressure and middle atmosphere temperatures and winds indicate that a substantial nonmigrating component is present in the diurnal tide. The nonmigrating tides, which propagate with a zonal phase ...

Abstract: Marine stratiform cloudiness (MSC) (stratus, stratocumulus, and fog) is widespread over subtropical oceans west of the continents and over midlatitude oceans during summer, the season when MSC has maximum influence on ...
