Abstract: A theory of propagation of acoustic-gravity waves in a temperature- and wind-stratified atmosphere is developed. It is shown by using suitable wind structure in a COSPAR standard atmosphere that both the normal dispersion ...

Abstract: The variability which arises in the GISS Global Climate-Middle Atmosphere Model on two time scales is reviewed: interannual standard deviations, derived from the five-year control run, and intraseasonal variability as ...

Abstract: The effects of volcanic aerosols on the middle atmosphere are investigated with the Goddard Institute for Space Studies (GISS) Global Climate/Middle Atmosphere model. Volcanic aerosols with a visible optical depth of 0.15 ...

Abstract: Short-period internal gravity waves recorded at Palisades, N.Y., have been found to associated with a rapidly moving pressure rise explained as a very long gravity wave. The speeds of propagation of both the pressure rise ...

Abstract: The impact of doubled atmospheric CO2 on the climate of the middle atmosphere is investigated using the GISS global climate/middle atmosphere model. In the standard experiment, the CO2 concentration is doubled both in the ...

Abstract: We propose that traveling internal gravity waves, like the lee waves referred to by Lilly, can have a significant effect in the vertical transfer of kinetic energy and momentum from the westerly flow. A program to study ...

Abstract: The response of the troposphere?stratosphere system to doubled atmospheric CO2 is investigated in a series of experiments in which sea surface temperatures are allowed to adjust to radiation imbalances. The Goddard Institute ...

Abstract: The GISS global climate model (Hansen et al.) has been extended to include the middle atmosphere up to an altitude of approximately 85 km. The model has the full array of processes used for climate research, i.e., numerical ...
