ABSTRACT
The response of the equatorial quasi-biennial
oscillation (QBO) to zonal-mean ozone perturbations
consistent with the 11-year solar cycle is examined using
a 2 1/2 dimensional model of the tropical stratosphere.
Unique to this model are wave-ozone feedbacks, which
provide a new, nonlinear pathway for communicating solar
variability effects to the QBO. Model simulations show that
for zonal-mean ozone perturbations representative of solar
maximum (minimum), the diabatic heating due to the wave-ozone
feedbacks is primarily responsible for driving a
slightly stronger (weaker) QBO circulation and producing a
slightly shorter (longer) QBO period. These results, which
are explained via an analytical analysis of the divergence
of Eliassen-palm flux, are in general agreement with
observations of quasi-decadal variability of the QBO.
