We present an analysis of time correlations between measurements of solar radius, neutrino flux data, and acoustic mode frequency shifts. We find significant anticorrelation of the first two quantities with the last one. Variations are found over time scales of order the 11 yr solar cycle and at shorter time scales. The shorter periods, of order 1 yr, are better detected during the period 1985-1991. These correlations strongly suggest the possibility that dynamical processes detected in upper solar layers are closely related with perturbations inside the sun, down to the core.
