Other Abstract

Empirical mode decomposition (EMD) technique is used to study the Rieger-type cycle in the sunspot area data from the 12th to 24th solar cycles and their phase relations in the northern and southern hemispheres. It is found that: (1)the Rieger-type cycle scale and the time scale are different in the two hemispheres, which leads to the asymmetry of the hemispheric distribution; (2)the average Rieger-type cycle length in the northern hemisphere is slightly longer than that in the southern hemisphere; (3)the phase of the dominant hemisphere is not necessarily ahead of time. The hemispherical Rieger-type with similar cycle scales is not necessarily a strong correlation.
