Abstract: The leading modes of month-to-month variability in the Northern and Southern Hemispheres are examined by comparing a 100-yr run of the Geophysical Fluid Dynamics Laboratory GCM with the NCEP?NCAR reanalyses of observations. ...

Abstract: The two-day wave is observed in the Upper Atmosphere Research Satellite Microwave Limb Sounder temperature data around 40?58 km. Between December 1991 and September 1994, the two-day wave temperature signature is most ...

Abstract: Motivated by recent evidence of strong stratospheric?tropospheric coupling during the Northern Hemisphere winter, this study examines the evolution of the atmospheric flow and wave fluxes at levels throughout the stratosphere ...

Abstract: The middle atmosphere version of the National Center for Atmospheric Research Community Climate Model 2 (MACCM2) mechanistic model is used to simulate several aspects of the observed two-day wave near the stratopause and ...

Abstract: The authors apply principal component analysis (PCA) to the extratropical total column ozone from the combined merged ozone data product and the European Centre for Medium-Range Weather Forecasts assimilated ozone from ...

Abstract: A principal component analysis (PCA) is applied to the Southern Hemisphere (SH) total column ozone following the method established for analyzing the data in the Northern Hemisphere (NH) in a companion paper. The interannual ...
