The middle latitudes, also called the mid-latitudes or moderate latitudes, are spatial regions on either hemisphere of Earth, located between the Tropic of Cancer and the Arctic Circle (66°33′50.4″) in the northern hemisphere and between the Tropic of Capricorn (-23°26′09.6″) and the Antarctic Circle (-66°33′50.4″) in the southern hemisphere. They include Earth's subtropical and temperate zones, which lie between the two tropics and the polar circles. Weather fronts and extratropical cyclones are usually found in this area, as well as occasional tropical cyclones or subtropical cyclones, which have traveled from their areas of formation closer to the Equator.
