Artificial stimulation of rain in the subtropical arid area by the artificially modified mesoscale solar thermal energy release to the atmosphere is discussed. For the effective stimulation of cumulus convection in which a cumulus or cumulonimbus with rain drops is considerd to grow, it is important to supply sufficient thermal energy and water vapour within the period of growing stage of cumulus convection. The use of accumulated solar thermal energy is proposed for this purpose.
