Abstract

We show that a random flow that depends on space and time generates a mode which is damped and move slower than the coherent f -mode as well as possesses properties which are consistent with the recent SOHO/MDI data (Antia & Basu 1999).

Key words: convection – Sun: atmosphere – Sun: granulation – Sun: oscillations – turbulence
