Stratospheric temperature trends: impact of ozone variability and the QBO

In most climate simulations used by the Intergovernmental Panel on Climate Change 2007 fourth assessment report, stratospheric processes are only poorly represented. For example, climatological or simple specifications of time-varying ozone concentrations are imposed and the quasi-biennial oscillation (QBO) of equatorial stratospheric zonal wind is absent. Here we investigate the impact of an improved stratospheric representation using two sets of perturbed simulations with the Hadley Centre coupled ocean atmosphere model HadGEM1 with natural and anthropogenic forcings for the 1979-2003 period. In the first set of simulations, the usual zonal mean ozone climatology with superimposed trends is replaced with a time series of observed zonal mean ozone distributions that includes interannual variability associated with the solar cycle, QBO and volcanic eruptions. In addition to this, the second set of perturbed simulations includes a scheme in which the stratospheric zonal wind in the tropics is relaxed to appropriate zonal mean values obtained from the ERA-40 re-analysis, thus forcing a QBO. Both of these changes are applied strictly to the stratosphere only. The improved ozone field results in an improved simulation of the stepwise temperature transitions observed in the lower stratosphere in the aftermath of the two major recent volcanic eruptions. The contribution of the solar cycle signal in the ozone field to this improved representation of the stepwise cooling is discussed. The improved ozone field and also the QBO result in an improved simulation of observed trends, both globally and at tropical latitudes. The Eulerian upwelling in the lower stratosphere in the equatorial region is enhanced by the improved ozone field and is affected by the QBO relaxation, yet neither induces a significant change in the upwelling trend.

“…The Nimbus 7 Solar Backscatter Ultraviolet (SBUV) instrument was launched in October 1978 to measure stratospheric ozone profiles and also made daily spectral solar UV measurements until February 1987 in the wavelength region 160-400 nm [Heath et al, 1975]. Deploying the diffuser plate only for solar observations reduced the overall degradation rate, and varying the frequency of solar observations provided data used to model long-term changes in diffuser reflectivity and instrument throughput Herman et al, 1990;Schlesinger and Cebula, 1992].…”

“…The primary objective of the SBUV instrument was the measurement of stratospheric ozone profiles using backscattered UV radiation [Heath et al, 1975]. Nimbus 7 SBUV also made daily spectral solar UV measurements in the wavelength region 160-400 nm at 1.1-nm resolution from November 1978 to February 1987 by deploying a diffuser plate to direct sunlight into the nadir-viewing instrument.…”

We find reasonable agreement between the NOAA 11, SOLSTICE, and SUSIM results at all wavelengths in the 170-400 nm region. Power spectral analysis gives consistent results for all three instruments on solar rotational timescales, and reveals the evolution of solar rotation periodicity and strength during a solar cycle. We find significant differences between instruments in both period and spectral location when the spectral irradiance data are analyzed on intermediate (50-250 days) timescales. The NOAA 11 spectral irradiance data provide a valuable complement to the UARS solar data, and capture the entire maximum of solar cycle 22.
