The subsequent development of the phenomenological model of the solar convective zone is carried out. The cophasal region, in which unilateral movement of the matter is supposed, is considered. Quantitative relations for kinematic parameters of solar sport groups, agreeing well with the observations, are given. The cophasal regions distribution due to their linear dimensions is obtained. It is shown that the effective depth of the convective zone is found to change with the phase of the activity cycle: less in the minimum and more in the maximum of activity.
