dc.description.abstract | We consider the effect of stratification on systematic, large-scale flows generated in anelastic
convection. We present results from three-dimensional numerical simulations of convection in a
rotating plane layer in which the angle between the axis of rotation and gravity is allowed to
vary. This model is representative of different latitudes of a spherical body. We consider two
distinct parameter regimes: (i) weakly rotating and (ii) rapidly rotating. In each case, we examine
the effect of stratification on the flow structure and heat transport properties focussing on the
difference between Boussinesq and anelastic convection. Furthermore, we show that regimes (i) and
(ii) generate very different large-scale flows and we investigate the role stratification has in modifying
these flows. The stratified flows possess a net helicity not present in the Boussinesq cases which we
suggest, when combined with the self-generated shear flows, could be important for dynamo action. | en_GB |
