Stratospheric Response to Climate/Solar Forcing (Invited Speaker)
David H. Rind, NASA, New York, NY; and J. Lean and C. McLinden
Climate impacts on the stratosphere associated with both long and short-term forcings are investigated with various versions of the GISS Global Climate/Middle Atmosphere Model 3. The impact of solar cycle variability is the focus of one set of experiments with answers provided to the following questions: (1) Does the solar cycle impact depend on the ozone response? (2) Does it extend into the troposphere? (3) Does it depend on model resolution? and (4) Is it obscured or amplified by other climate change forcings that have been occurring? On the (much) longer time-scale, the ice-age stratospheric climate is simulated with and without interactive ozone. An assessment is provided as to how stratospheric ozone might have been different in response to dynamical and photochemical influences.
