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
Macadamia tetraphylla have not done well in the pure tropics, with no fully successful plantations less than 15 degrees from the equator. Major plantations in Costa Rica, at 10 degrees north, are said to produce much less than in Hawaii at 19 to 22 degrees north, in one case 20% the production. Plantations in Guatemala at 15 degrees north are successful. However, individual seedling trees have produced well in the pure tropics and need to be selected. One grower noted that the integrifolia flowers in Costa Rica have no aroma, leading to low and erratic pollination. Macadamia tetraphylla has a higher sugar
