Sustaining the Sun's Magnetic Network with Emerging Bipoles

摘要: The Michelson Doppler Imager experiment on SOHO has revealed a "magnetic carpet" dominated by the emergence of bipolar magnetic flux in ephemeral active regions, which subsequently split into small elements that drift network. effects granular and supergranular convection these are represented here kinematic modeling: Elementary tubes transported passively flow, while experiencing random displacements produced granulation. They end up network surrounds supergranules, where they eventually meet oppositely directed fields annihilated. model calculations show total unsigned will decay within few days unless it is continually replenished. A statistically steady state with 2-3 × 1023 Mx over whole solar surface can be maintained if emerges at rate 7 1022 day-1, as indicated published measurements regions appear.
