摘要

The north - south (N - S) asymmetry of solar activity is investigated by using the data on coronal green-line brightness and total number and total area of sunspots over the period of 1939 - 2001. Typical time variations of the N - S asymmetry are found to be consonant in these indices. Quasi-biennial oscillations (QBO) of solar activity are well recognizable in the N - S asymmetry of the examined indices. Moreover, the QBO are much better manifested in the N - S asymmetry of the individual indices than in the original ( N plus S) indices. The time variations of relative QBO power are synchronous for the N - S asymmetry of various solar activity indices whereas such a synchronization is weaker for the indices themselves. It is revealed that the relative QBO power found in the N - S asymmetry of the studied indices has a negative correlation with the value of the N - S asymmetry itself. The findings indicate that the N - S asymmetry should be regarded as a fundamental phenomenon of solar activity similarly manifested in different activity indices. These findings should be taken into account when any dynamo theory of solar activity is constructed.
