The impact of the equilibrium temperature distribution, θE,on the Hadley circulation simulated by an axisymmetric model is studied. TheθE distributions that drive the model are modulated here bytwo parameters, n and k, the former controlling the horizontal broadnessand the latter controlling the vertical stratification ofθE. In the present study, variations in theθE distribution mimic changes in the energy input of theatmospheric system, leaving as almost invariant the Equator–polesθE difference. Both equinoctial and time-dependent Hadleycirculations are simulated and the results compared. The results giveevidence that concentrated θE distributions enhance themeridional circulation and jet wind speed intensities, even with a lowerenergy input. The meridional circulation and the subtropical jet streamwidths are controlled by the broadness of horizontal θErather than by the vertical stratification, which is important only whenθE distribution is concentrated at the Equator. The jetstream position does not show any dependence with n and k, except whenthe θE distribution is very wide (n = 3) and, in sucha case, the jet is located at the mid-latitudes and the model temperatureclamps to forcing θE. Using n = 2 and k = 1, wehave the formulation of the potential temperature adopted in the classicalliterature. A comparison with other works is performed, and our results showthat the model running in different configurations (equinoctial, solstitialand time dependent) yields results similar to one another
