Although the physical mechanism of the sunspot cycle is not well‐known, we can adequately predict its behaviour through empirico‐statistical methods. Working on the so‐called areas index Iaof the solar activity (Xanthakis, 1969, 1970; Poulakos and Tritakis, 1972; Tritakis, 1974, 1978) we have defined some useful relations which help to predict various basic parameters of the sunspot cycle and its profile, as well.
