evidence

The winter temperature contrast between western Europe and eastern North America is principally caused by atmospheric advection and the seasonal release of stored ocean heat, not by heat convergence from the Gulf Stream; the older claim is traced to Maury.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
