thermal equator

noun

1. an imaginary line round the earth running through the point on each meridian with the highest average temperature. It lies mainly to the north because of the larger landmasses and therefore greater summer heating

Example Sentences

Because the Northern Hemisphere has more landmass, it is heating up faster than the Southern Hemisphere, and, as some climate models have suggested, this could push the thermal equator northward, and along with it those key rain belts.

From Scientific American

What this could mean, the authors posit, is that as the boreal winter continues to warm disproportionately, the thermal equator and therefore the rain belts won’t travel as far south as they currently do during the winter.

From Scientific American

These and other paleoclimate records indicate that rain belts shifted northward along with the thermal equator because of the global heat imbalance.

From Scientific American

From Project Gutenberg

The shifting of the thermal equator, and with it the direction of the trade winds, would divert some of the warm ocean currents from the cold regions, and this effect was greatly enhanced, he considered, by the configuration of the Atlantic Ocean.
