Computation of Possible Climatic Consequences of Perturbations to Stratospheric Aerosols,Ozone and Water Vapor with Radiative-Convective Models.

摘要

Presented is a summary of the results of experiments performed using a new radiative-convective model developed as part of the CIAP funded research. The experiments tested the sensitivity of the thermal structure of the atmosphere to changes in the solar 'constant';the stratospheric ozone profile;and the concentration of water vapor in the stratosphere. The findings agree qualitatively with the earlier results obtained by Manabe and Wetherald (1967) and Callis et al. (1975) and to the extent that results from different models should be compared,the quantitative agreement is also good. In addition the results of a simple energy balance model which can be used to estimate the sensitivity of the global mean surface temperature to changes in the stratospheric aerosol layer are reported. This model,also developed for this CIAP study,includes the effects of the particles on both solar and terrestrial radiation and reveals a coupling between the planetary albedo,the stratospheric aerosol layer,and the surface temperature that was overlooked during the CIAP time frame.
