Middle latitudes Middle latitudes The middle latitudes (also called the mid-latitudes, sometimes midlatitudes, or moderate latitudes) of Earth lie between 23°26'22" and 66°33'39" north, and between 23°26'22" and 66°33'39" south. They include Earth's subtropical and temperate zones, which lie between the tropics and the polar circles (between the Tropic of Cancer and the Arctic Circle, and between the Tropic of Capricorn and the Antarctic Circle). Weather fronts and extratropical cyclones are usually found in this area, as well as occasional tropical cyclones, which have traveled from their areas of formation closer to the Equator. The prevailing winds in the middle latitudes are
Bowerchalke the equator, the latitude of present-day Argentina. 'Proto-Bowerchalke' and the rest of England and Wales are part of Avalonia, a micro-continent that broke away from the southern landmass, and was 50 degrees south of the equator about 500 mya. It joined with Baltica just south of the equator 400 mya, and was crushed between Baltica, and Laurasia (North America), and Gondwanaland (Africa, Australia, Antarctica and South America) 350 mya whilst near the equator (Variscan orogeny). Avalonia was landlocked and buffeted within Pangaea just north of the equator 270 mya, and became part of a desert in the northern tropics 230
