Retreat of glaciers since 1850 doing so due to transient local weather conditions, which have brought more precipitation and cloudier, cooler summers since 2002. Tropical glaciers are located between the Tropic of Cancer and the Tropic of Capricorn, in the region that lies 23° 26′ 22″ north or south of the equator. Strictly, a tropical glacier is located within the astronomical tropics; the area where the annual temperature variation is less than the daily variation, and is within the oscillation area of the Intertropical Convergence Zone. Tropical glaciers are the most uncommon of all glaciers for a variety of reasons. Firstly, the regions are the
Tropical rain belt the lower atmosphere, the abundant moisture from the tropics loses the ability to be stored in the atmosphere. As a result, the excess moisture that cannot be held by the colder air is then turned into thunderstorms and rain showers. These thunderstorms and rain showers are usually located along the equator, but they will extend out to the Tropic of Cancer, which is the 23.5 north latitude, as well as the Tropic of Capricorn, which is the 23.5 south latitude. It is largely a manifestation of the ITCZ (pronounced "itch"). The tropical rain belt lies in the southern hemisphere of
