Short summary

Midlatitude storm tracks are stronger over ocean basins than continents, and also stronger in the Southern Hemisphere than in the Northern Hemisphere. It is still not clear how Earth's land-ocean distribution, ocean heat transport, and orography, set up this structure. We use an intermediate complexity moist general circulation model to reveal substantial non-additivities in the response to these inhomogeneities, and then diagnose why.
