    Sensitivity of tracer transports and stratospheric ozone to sea surface temperature patterns in the doubled CO 2 climate

    Abstract: Two sets of sea surface temperature/sea ice changes are used to test the sensitivity of tracer transport to the pattern of warming in the doubled CO 2 climate. One set (2CO2WT) has greater tropical and high latitude sea surface temperature changes than the other (2CO2), although both fall within the range of plausible response. Simulations were done both with and without interactive ozone. Results show that the SST pattern affects the circulation change throughout the troposphere and middle atmosphere; the ozone interaction affects primarily the upper stratosphere, but through wave‐mean flow interaction has effects that extend down into the upper troposphere. Both experiments feature increased tropospheric/stratospheric exchange at low latitudes and greater vertical mixing within the troposphere; only the WT experiments result in increased interhemispheric transport and a more direct circulation in the high latitude stratosphere. Ozone increases in the upper stratosphere and decreases in the lower stratosphere in all the simulations, with greater transport of high latitude ozone into the troposphere in the WT runs. At sea level there is a more positive phase of the Arctic Oscillation (AO)‐type oscillation, and this is also true at 100 mbar, but there is no significance in the middle troposphere and the sign is different in the middle stratosphere. Many of these results differ from those generated in older versions of the GISS GCMAM despite the same SST forcing due to differences in control run characteristics, which has implications for model intercomparison experiments.

    Downward Coupling between the Stratosphere and Troposphere: The Relative Roles of Wave and Zonal Mean Processes*
    American Meteorological Society ; 2004
    In:  Journal of Climate Vol. 17, No. 24 ( 2004-12-15), p. 4902-4909

    In: Journal of Climate, American Meteorological Society, Vol. 17, No. 24 ( 2004-12-15), p. 4902-4909
    Abstract: Wave and zonal mean features of the downward dynamic coupling between the stratosphere and troposphere are compared by applying a time-lagged singular value decomposition analysis to Northern Hemisphere height fields decomposed into zonal mean and its deviations. It is found that both zonal and wave components contribute to the downward interaction, with zonal wave 1 (due to reflection) dominating on the short time scale (up to 12 days) and the zonal mean (due to wave–mean-flow interaction) dominating on the longer time scale. It is further shown that the two processes dominate during different years, depending on the state of the stratosphere. Winters characterized by a basic state that is reflective for wave 1 show a strong relationship between stratospheric and tropospheric wave-1 fields when the stratosphere is leading and show no significant correlations in the zonal mean fields. On the other hand, winters characterized by a stratospheric state that does not reflect waves show a strong relationship only between stratospheric and tropospheric zonal mean fields. This study suggests that there are two types of stratospheric winter states, characterized by different downward dynamic interaction. In one state, most of the wave activity gets deposited in the stratosphere, resulting in strong wave–mean-flow interaction, while in the other state, wave activity is reflected back down to the troposphere, primarily affecting the structure of tropospheric planetary waves.

    The leading variability mode of the coupled troposphere‐stratosphere winter circulation in different climate regimes
    American Geophysical Union (AGU) ; 2000

    Abstract: The leading variability mode of the coupled troposphere‐stratosphere winter circulation in the Northern Hemisphere (NH) describes a close relationship between the strength of the stratospheric cyclonic vortex and the index of a tropospheric wave‐like pattern covering the North Atlantic‐Eurasian region. This mode can be determined by applying singular value decomposition analysis between the time series of winter mean NH 50‐ and 500‐hPa geopotential heights. We compared the features of the leading coupled variability mode between two climate regimes, determined from a 1900‐year integration with the coupled atmosphere‐ocean climate model ECHAM3‐LSG. The two regimes differ on the interdecadal timescale in the strength of the stratospheric polar vortex and therefore in the transmission‐refraction properties of vertically propagating tropospheric waves. The spatial structures of the leading coupled variability mode of observational data better match the corresponding structures of the model's weak polar vortex regime (PVR) than those of the strong one. Because of the more effective tropospheric trapping of stationary wave energy of zonal wave number (ZWN) 2 at midlatitudes, the zonal variability structure of this wave is changed by barotropic effects in the troposphere as well as in the stratosphere. The coupled troposphere‐stratosphere mode and the response of winter circulation were studied in a climate‐change experiment carried out with the same model. We could show that under increased greenhouse gas forcing, both the response and the coupled variability mode between tropospheric and stratospheric circulation itself has a high similarity to the leading coupled mode in the strong PVR.
