Abstract
The Sun's supergranulation is considered as a collective
effect provided by a statistical ensemble of narrow upflow jets. The
responsibility for their occurrence rests with the Rayleigh-Taylor
blow-up instability. It is this mechanism that is a trigger for the
collapse of thermal irregularities and leads to the formation of such
jets. The scaling laws of turbulence generated by these jets are
discussed.
