STATE VARIABLES FOR SOLAR ACTIVE REGIONS
Abstract:In this paper, several integral parameters of solar active regions are defined. The values of these parameters can be calculated from observational data. It is shown that only five of them are independent. These five parameters are sufficient for uniquely defining the active region current physical state. Such five parameters are proposed to be regarded as the state variables for solar active regions.
