Energetic constraints on the time-dependent response of the intertropical convergence zone (ITCZ) to volcanic eruptions are analyzed using the Community Earth System Model Last Millennium Ensemble project. The energetic constraints are found to vary during the first few years, governed by conjoined variations of the energy budgets of the stratosphe...
Article
An intermediate complexity moist General Circulation Model is used to investigate the forcing of stationary waves in the Northern Hemisphere boreal winter by land-sea contrast, horizontal heat fluxes in the ocean, and topography. The additivity of the response to these building blocks is investigated. In the Pacific sector, the stationary wave patt...

... We use the ensemble mean to maximize the signals, but the results might be affected by the proxy overlap among the 11 available ENSO indices. The divergent ENSO 26,27 and hydrology 47,51-54 responses, plus the time-dependent shifts of the Intertropical Convergence Zone (ITCZ) 55 to volcanic eruptions with asymmetric hemispheric distributions further complicate the volcano-EASM relationship quantification. Future study expanding to Northern or Southern Hemispheric eruptions should correct for SST variations associated with such ITCZ shifts. ...
... Chang (2009) showed that extratropical (north of 25° N) diabatic heating and Tibetan Plateau forcings explain most of the planetary waves in model simulations. Garfinkel et al. (2020) illustrated that the strength of a planetary wave response to a given forcing depends on the background-state temperature field set by each forcing. As pointed out by Held et al. (2002), prior studies have mainly analyzed the response to heat sources as obtained from observations or general circulation models, rather than first determining the diabatic heating distribution generated from the lower boundary conditions. ...
