The authors study possible correlations between stratospheric cooling trends and increased circulation in the northern hemispheric troposphere in the period 1979 to 1992. These changes are compared with the effect of stratospheric heating which resulted from several aerosol injections from major volcanic activity during this period. These injections act much like an external forcing function applied to the stratosphere, and allow one to infer information on the response of the stratosphere/troposphere system to this dynamic input. For both cases one can observe perturbations in the zonal/mean zonal winds propogating into the troposphere.
