A GCM Study of the Climatic Effect of 1979-1992 Ozone Trend

摘要

The climatic effect of the column ozone trend derived from TOMS data is investigated using an updated version of GENESIS general circulation model (GCM). The GCM employs a newly constructed ozone climatology that includes longitudinal variation. In the perturbed simulation, the O3 trend is assumed to be confined to the lower stratosphere, and imposed in transient from January 1979 to December 1992 to incorporate both seasonal variations and linear year to year changes.
