Banana belt

A banana belt is any segment of a larger geographic region that enjoys warmer weather conditions than the region as a whole, especially in the wintertime. The term "banana belt" is broad enough that it can be used to describe everything from the entire Antarctic Peninsula, to the southern part of the American Midwest, to microclimate areas of mountain ranges.

Banana belts of the latter type may form on the lee sides of mountain slopes caused by orographic lift. When air rises over the top of a mountain range, it cools and releases moisture on the windward slope. As the air is pulled down the other side, it is compressed and heated via adiabatic heating, and it warms and dries territory in the mountain's rain shadow.

United States

 * Menominee, Escanaba, Manistique, and Iron Mountain, Michigan are in the banana belt of the Upper Peninsula of Michigan.
 * The Arkansas River Valley in Colorado, located in the Rocky Mountains, east of the Continental Divide and below the Sawatch Range of 14,000 foot peaks, is often referred to as a banana belt. It includes the towns of Buena Vista, Salida, Parkdale, Cañon City to Pueblo, Colorado.
 * The portion of the Oregon Coast region south of Port Orford is known as "Oregon's Banana Belt" because of its mild climate in relation to the rest of the coast. The largest communities in this region are Brookings-Harbor and Gold Beach.
 * The Lewis-Clark Valley straddling the Washington/Idaho state line is known as the "Banana Belt of the Inland Pacific Northwest". The area includes Lewiston, Idaho and Clarkston, Washington, both located at the confluence of the Snake and Clearwater Rivers.
 * The Treasure Valley area of Southwest Idaho that includes the capital of Boise, Idaho and surrounding communities is known as Idaho's Banana Belt. Residents enjoy year-round golfing, while being only a short drive away from skiing.

Europe

 * Western Europe, and Northern Europe, including the United Kingdom and Ireland have mild winters due to the warming effects of the North Atlantic Current.

Australia

 * In the cool season, due to the southeast Australian foehn, the southeastern coast of New South Wales, which includes cities such as Newcastle, Sydney, Wollongong, Batemans Bay, Merimbula, and Narooma, is relatively warmer than the inland regions of the state (i.e. Central Tablelands, South Western Slopes and the Central West).
