WebAug 19, 2008 · In this visualization, we illustrate the fluid flows in the Sun which drive the solar magnetic dynamo. The flows can be considered as a combination of two components, a toroidal component and a meridional component. The toroidal flow corresponds to the rotational motion of the Sun. In the cut-away view, this motion is represented by the … WebThis paper reviews recent advances and current debates in modeling the solar cycle as a hydromagnetic dynamo process.

WebIn their 3D dynamo models,Miesch & Dikpati(2014) andMiesch & Teweldebirhan (2016) adapted a double-ring algorithm in which BMRs are directly placed at the solar surface. In these types of models however the flux emergence in the convection zone is miss-ing, which is believed to be an important aspect of the solar magnetic cycle. WebFeb 1, 2011 · We investigate the dynamo underpinning of solar cycle precursor schemes based on direct or indirect measures of the solar surface magnetic field. We do so for various types of mean-field-like kinematic axisymmetric dynamo models, where amplitude fluctuations are driven by zero-mean stochastic forcing of the dynamo number …
