INFLUENCE OF THERMAL HEATING ON THE DYNAMICS OF FLOATING MAGNETIC FIELDS IN THE SOLAR ATMOSPHERE
The paper considers the role of heat fluxes within an emerging magnetic tube when the tube emerges to the surface of the Sun from the bottom of convective zone. It is shown that within legs of the magnetic tube arc the amplitude of heat flux density may rise up to 10<sup>5</sup> erg/cm<sup>2</sup>/sec. The heating has transient nature and its character depends on the mode of Parker instability developing.
