QUANTITATIVE PARAMETERS OF MAGNETIC AND VELOCITY FIELDS IN SOLAR ACTIVE REGIONS

摘要

The quantitative parameters were calculated on the basis of magnetic and velocity fields observations of the solar active regions (AR). The downflows velocity flux was significantly higher than the upflows velocity flux in each AR under analysis. The structures of the magnetic and velocity fields were found to be essential different. No relation between the velocity and magnetic fluxes changes was fixed. The cases of anticorrelation between variations of AR sunspots area and magnetic flux were found. It was obtained that the rapid changes of radial velocity field precede the X-ray flares in the AR.
