Abstract: We examine the dynamical mechanisms that control heat transport
in atmospheres of tidally locked planets. Current estimates of heat
redistribution in atmospheres of hot Jupiters generally only consider
the equilibrium of stellar irradiation and advection. In this work, we
show that gravity waves can effectively transport heat on global scales
in atmospheres of tidally locked planets. A simple 1D atmospheric
shallow-water model is used to study the day/night temperature contrast
as a function of the radiative, advective, frictional, and wave-travel timescales
of the atmosphere. We qualitatively compare our results with those made by
2D non-linear shallow-water simulations. .
