THE LATITUDE DISTRIBUTION OF SMALL-SCALE MAGNETIC ELEMENTS IN SOLAR CYCLE 23

摘要: With the unique data set from full-disk observations provided by Michelson Doppler Imager on board Solar and Heliospheric Observatory in interval embodying solar cycle 23, we have found that cyclic variations of numbers total flux these small-scale magnetic elements covering fluxes (2.9-32.0) Multiplication-Sign 10{sup 18} Mx (4.27-38.01) 19} show anticorrelation correlation with sunspots, respectively. In this study, time-latitude distributions anticorrelated correlated are analyzed. The following results disclosed: (1) for elements, low-latitude middle-latitude regions a longer duration maximum phase than an active region (AR) corresponding latitude region; shows accordant south-north asymmetry AR; distribution their number displays similar butterfly diagram but is twice as wide sunspots. (2) For variation different sunspot diagram; each latitude, always sunspots; duringmore » average speed peak latitudinal migration reaches 7.5 deg year{sup -1}, almost three times These seem to imply debris decayed source affected or modulated field.« less
