Abstract
The dependence of the correlation coefficient r(h, fo) between the stratospheric parameter h(100) and the critical frequency foF2 on geomagnetic activity is studied. In one of the previous publications of the authors, a general conclusion was drawn that if one chooses for the analysis only the days with geomagnetic index Ap < 12, this coefficient grows. In this paper we present a more complicated and statistically substantiated analysis of the effect of the r(h, fo) dependence on the limitations on Ap imposed on the analyzed days. Wide range of limitations on Ap from Ap = 4 to Ap = 40, five stations, and years of high (1980) and low (1987) solar activity are considered.
