Abstract
We have investigated the influence of heating in the D''-layer on the convection dynamics for the Rayleight number Ra = 10(6). Strong heatin g, which may represent a local small-scale heat transfer in the D''-la yer, results in an increase of lateral heterogeneities near the upper and lower boundaries, the blob-like structure of upwellings and the st abilization of the convection pattern. The influence of the electromag netic heating was found to be too weak to produce any substantial effe ct which is in contrast with the idea of Braginskii and Meitlis [1].
