DESCRIPTION:Speakers: Mr. DE CASO\, Luis (Instituto de Geofísica\, Univer
 sidad Nacional Autónoma de México)\nIn this work we report an analysis o
 f  various  indices of solar magnetic variability\nof closed and open fiel
 d\, concentrating  particularly in the quasi-biennial\nperidicities (1.7-2
 .5 years). The wavelet technique is used  in the time series of\nthe solar
  indices to find the significant periodicities of our study\, we also use\
 nother wavelet analysis already made. We consider the theory of a double s
 olar dynamo\,\nwith its low frequency component  located at the base of th
 e covection zone\, and its\nhigh frequency component  in the upper part\, 
 coupled by the helicity (alfa effect).\nIn this context\, we obtain  a cla
 ssification of the couplings between the low and\nhigh frequency component
 s per cycle along cycles 17 to 23\, based on the strength and\nregularity 
 of the quasi-biennial periodicities.\n\nhttps://indico.nucleares.unam.mx/e
