| 英文摘要 | Quasi-biennial oscillation ( QBO) of solar magnetic activities is intrinsic to dynamo mechanism, but still far from fully understood. In this work, the phase and amplitude asymmetry of solar QBO of H alpha flare activity in the northern and southern hemispheres is studied by the ensemble empirical mode decomposition, the cross-correlation analysis, and the wavelet transform technique. The following results are found: ( 1) solar QBO of H alpha flare index in the two hemispheres has a complicated phase relationship, but does not show any systematic regularity; and ( 2) the solar cycle mode of solar H alpha flare index in the northern hemisphere generally leads that in the southern one by nine months for the time interval from 1966 to 2014. The possible origin of these results is discussed. |
