“…The zonal mean temperature difference field is consistent with these changes, being negative at the summer pole in the upper mesosphere. Note that both experiments exhibit mean mesospheric temperatures that are in qualitative agreement with observations and that depart from the radiatively determined temperature [Fels, 1985] …”

Abstract.The zonal mean circulation of the middle atmosphere simulated by a general circulation model that includes the Doppler spread parameterization of gravity-wave momentum deposition is presented. To illustrate the impact of the parameterization, this simulation is compared to another obtained by using Rayleigh friction instead. It is found that the Doppler spread parameterization improves the extratropical zonal mean circulation in the mesosphere by reducing the strength of the zonal winds above the jet maximum. The parameterization also improves the simulation of the equatorial semiannual oscillation in the zonal mean zonal wind at the stratopause by enhancing the eastward phase and its downward propagation.

“…A similar recurrence of the major warming in the NH takes place in the simulation with the 3° latitude GFDL "SKYHI" GCM (Fels, 1985). Also in the simulation with a mechanistic model, final warmings occur in both hemispheres every year (Holton and Wehrbein, 1980b).…”

Results are presented from a numerical simulation of the stratospheric circulation using a spectral general circulation model of the Meteorological Research Institute. The model has 23 layers in the vertical extending from the surface to approximately 70 km in the middle mesosphere and uses the spectral transform method with a rhomboidal 13 truncation. The model includes all major physical processes as well as realistic radiative transfer. The model also includes Rayleigh damping as a parameterization of gravity wave breaking. The model has been run for two years, and the results are compared with observations.The model generally simulates the overall stratospheric fields of temperature and winds reasonably well. Seasonal variations of the stratospheric fields are also successfully reproduced. Successful aspects of the current simulation include: clear separation of the subtropical and polar night jet streams; stratospheric summer easterlies of the proper speed and extent; interhemispheric differences in the stratospheric circulation; major and minor sudden warming events; and an equatorial semi-annual oscillation. Obviously deficient results include: excessively cold polar night vortices; and much less westerly winds in the equatorial semi-annual oscillation.A simulated final warming in the Northern Hemisphere and a minor warming in the Southern Hemisphere are briefly described, along with the evolution of easterlies from late-winter to spring.

“…The radiation code was developed at GFDL (Lacis and Hansen 1974;Fels andSchwarzkopf 1975, 1981;Fels 1985;Schwarzkopf and Fels 1991) and allows for annual and diurnal cycles. The spectrum of radiation is separated into solar (shortwave) and terrestrial (longwave) bands which are treated independently.…”
