| 摘要 | The rotation signal on the full disc of the solar chromosphere was studied by using the Ca II K normalized intensity from 938 Carrington rotation (CR) synoptic maps (from CR827 to CR1764) obtained from the Mount Wilson Observatory during the period of 1915 August 10 to 1985 July 7. In this study, our main focus is on the distribution characteristics of the rotation signal on the full disc of the solar chromosphere and its variation with the solar cycle. We found that the chromospheric rotation signal is more pronounced in the latitudinal belt of sunspot activity and tends to extend to higher latitudes, and the trend is essentially the same for each solar cycle. The chromospheric rotation signal is also found to have phase differences in latitudes. The period of the chromospheric rotation signal varies regularly in latitudes, but its phase variation is irregular. In addition, we found that the intensity background is lowest in the latitudinal belt of sunspot drift where the chromospheric rotation signal is generated, but it increases with latitude and tends to extend to higher latitudes. We discussed the possible mechanisms of the above analysis results and thought that the chromospheric rotation signal is mainly caused by sunspots and plages. |
