Interactive comment on “Dynamics of the Hadley circulation in an axisymmetric model undergoing periodic change in forcing stratification” by Nazario Tartaglione

This short paper describes a numerical model study of an axisymmetric atmospheric circulation (somewhat akin to the Earth’s tropical Hadley circulation) subject to a periodic forcing that cyclically modifies the static stability. The configuration is not particularly realistic as a representation of the true circulation in the Earth’s tropics, but its motivation is justified as an idealized test of an hypothesis that at least some aspects of the observed response of the annular modes of the atmosphere to seasonal and intraseasonal variations of static stability may be determined by the axisymmetric circulation itself, independently of non-axisymmetric waves and eddies.
