dc.descriptionBy incorporating a large-scale shear flow into turbulent rotating convection, we show that a sufficiently strong shear can promote dynamo action in flows that in the absence of shear do not act as dynamos. Our results are consistent with a dynamo driven by either the shear-current effect or by the interaction between a fluctuating $α$-effect and the velocity shear; they are though inconsistent with either a classical $α^2$ or $αω$ mean field dynamo.
