On the Applicability of Two- and One-Dimensional Parameterizations of Atmospheric Tracer Transports to Prognostic Photochemical Models of the Stratosphere

摘要

This paper deals with the applicability of empirical parameterizations of stratospheric transports of chemically inert tracers to predictive or prognostic two- and one-dimensional photochemical models of the stratosphere and troposphere for the forecasting of anthropogenic effects on atmospheric ozone. The scope of this paper therefore includes: (1) a critical review and assessment of the prognostic utility of the parent Reed and German (1965) 2-D parameterization of stratospheric transports; (2) the implied assumption in representative subsidiary 2D parameterizations used or for use in 2-D photochemical models; (3) use of GCM/tracer model data for a chemically inert tracer for the assessment of the prognostic utility of both 2-D and 1-D parameterizations of stratospheric transports; and (4) the outlook for the development of prognostic parameterizations of stratospheric transports.
