Davis, Nicholas A.; Seidel, Dian J.; Birner, Thomas; Davis, Sean M.; Tilmes, Simone (2016): Changes in the width of the tropical belt due to simple radiative forcing changes in the GeoMIP simulations. In Atmos. Chem. Phys. 16 (15), pp. 10083–10095. DOI 10.5194/acp-16-10083-2016.

To shed light on robust processes associated with tropical expansion, here we examine how the tropical belt width, as measured by the Hadley cell edges, responds to simplified forcings in the Geoengineering Model Intercomparison Project (GeoMIP). The tropical belt expands in response to a quadrupling of atmospheric carbon dioxide concentrations and contracts in response to a reduction in the solar constant, with a range of a factor of 3 in the response among nine models.
