Dynamo models of the solar cycle
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.

WebWe develop two different solar dynamo models to verify the hypothesis that a deep meridional flow can restrict the apperance of sunspots below 45 degrees, proposed by Nandy & Choudhuri (2002). In the first one, a s… WebOct 5, 2024 · Over last two decades, the solar magnetic cycle has been modeled with great details using the Babcock–Leighton dynamo models, also named as the flux transport dynamo models (Choudhuri et al. 1995; Durney 1995; Dikpati & Gilman 2009; Charbonneau 2010; Karak et al. 2014). In this model, the poloidal field is generated from …
Web2 days ago · We, for the first time, try to model these observational trends using flux transport dynamo models. Following previous works, we build kinematic dynamo models of one solar mass star with different rotation rates. Differential rotation and meridional circulation are specified with a mean-field hydrodynamic model. WebI worked in the 1D and 2D solar dynamo models aimed at reproducing the solar magnetic cycle. I also developed studies in the area of models …
