abstract = "Using the standard solar omega-dynamo equations we formulate
appropriate initial and boundary conditions at the moment when the
toroidal component is maximum, so that we obtain the toroidal
magnetic field component as a function of the solar latitude. We
found a new non-homogeneous distribution for the toroidal
component along the latitude (<DeltaB(theta)/Deltatheta> given by
7G/degree, 24G/degree and 34G/degree for the respectives latitudes
ranges of 10degrees-15degrees, 16degrees-18degrees and
19degrees-25degrees) and this nonhomogenous decay rate is
statistically confirmed through a chi-square analysis of the Mt.
Wilson Sunspot data for two solar cycles. Based on this result one
can expect the most energetic magnetic eruptive phenomena to be,
in average, nonlinearly concentrated at latitudes ranging from 10
to 25 degrees in both hemispheres.",
