SUMMARY:Zonal Flow Generation by Convectively Excited Waves\, Plasma P
hysics (Physics/ECE/NE 922) Seminar\, Prof. Daniel Lecoanet\, Northwes
tern University
DESCRIPTION:Many natural systems have turbulent\, convective regions a
djacent to stably-stratified regions. This occurs in most stars\, the
Earth’s atmosphere\, and planetary cores. In all these systems\, the
turbulent convection can excite waves in the stably stratified region
. Although these waves carry nearly zero net momentum\, they can still
spontaneously generate zonal flows in the stable layers. In this talk
\, I will describe recent work to characterize the wave excitation pro
cess\, as well as the zonal-flow evolution induced by the waves. These
studies can help interpret recent zonal-flow measurements in the Eart
h’s atmosphere as well as in red giant stars.
