Latitudinal-Temporal Analysis of Long-Periodic Variations of Coronal Bright Points
The latitudinal-temporal changes in wavelet spectra for the number of coronal bright points (CBPs) in solar-activity (SA) cycles 23 and 24 are analyzed with the Morlet function. The number of CBPs at different latitudes is found to vary in different ways. The changes in the total number of CBPs show...

| description | The latitudinal-temporal changes in wavelet spectra for the number of coronal bright points (CBPs) in solar-activity (SA) cycles 23 and 24 are analyzed with the Morlet function. The number of CBPs at different latitudes is found to vary in different ways. The changes in the total number of CBPs show no noticeable relation with SA cycles. Conversely, the distribution of the spectral density of the CBP number at active and high latitudes and the equator, as well as the total CBP number, shows a pronounced agreement with the course of the SA cycle. An anticorrelation is observed for the high latitude zone. |
