A Puelche wind (in Spanish, viento puelche) is a dry foehn-like eastern wind that occurs in south-central Chile. The wind owns its name from the Puelche people who inhabited the eastern slopes of the Andes. Puelche winds are mainly caused by South Pacific high pressure extending eastwards across the Andes and/or building a ridge to an area of high pressure centered over the South Atlantic. Puelche winds appearing in spring can cause fast snow melt in the Andes, producing floods and reducing the albedo of glaciers.
The Andes, Andes Mountains or Andean Mountain Range are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is 8,900 km (5,530 mi) long, 200 to 700 km wide, and has an average height of about 4,000 m (13,123 ft). The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.

San Carlos de Bariloche, usually known as Bariloche, is a city in the province of Río Negro, Argentina, situated in the foothills of the Andes on the southern shores of Nahuel Huapi Lake. It is located within the Nahuel Huapi National Park. After development of extensive public works and Alpine-styled architecture, the city emerged in the 1930s and 1940s as a major tourism centre with skiing, trekking and mountaineering facilities. In addition, it has numerous restaurants, cafés, and chocolate shops. The city had a permanent population of 108,205 according to the 2010 census.

The Gününa küna, or sometimes, Puelche are indigenous peoples living east of the Andes Mountains in Chile and Southwest Argentina. They spoke the Puelche language. The name "Puelche" was not native, but was given to them by the Mapuche. They were annihilated by plagues and epidemics in the late 18th century, with survivors merging into other groups such as the Mapuche, Het, and Tehuelche.
Cuyo is the wine-producing, mountainous region of central-west Argentina. Historically it comprised the provinces of San Juan, San Luis and Mendoza. The modern New Cuyo includes both Cuyo proper and the province of La Rioja. New Cuyo is a political and economic macroregion, but culturally La Rioja is part of the North-West rather than of Cuyo.
San Martín de los Andes is a city in the south-west of the province of Neuquén, Argentina, serving as the administration centre of the Lácar Department. Lying at the foot of the Andes, on the Lácar lake, it is considered one of the main tourism destinations in the province. The National Route 40 runs to the city, connecting it with important touristic points in the south of the province, such as Lanín and Nahuel Huapí national parks.
Berg wind is the South African name for a katabatic wind: a hot dry wind blowing down the Great Escarpment from the high central plateau to the coast.
Penitentes, or nieves penitentes, are snow formations found at high altitudes. They take the form of elongated, thin blades of hardened snow or ice, closely spaced and pointing towards the general direction of the sun.
The geography of South America contains many diverse regions and climates. Geographically, South America is generally considered a continent forming the southern portion of the landmass of the Americas, south and east of the Colombia–Panama border by most authorities, or south and east of the Panama Canal by some. South and North America are sometimes considered a single continent or supercontinent, while constituent regions are infrequently considered subcontinents.
The climate of Chile comprises a wide range of weather conditions across a large geographic scale, extending across 38 degrees in latitude, making generalizations difficult. According to the Köppen system, Chile within its borders hosts at least seven major climatic subtypes, ranging from low desert in the north, to alpine tundra and glaciers in the east and southeast, tropical rainforest in Easter Island, Oceanic in the south and Mediterranean climate in central Chile. There are four seasons in most of the country: summer, autumn, winter, and spring.
The climate of Argentina varies from region to region, as the vast size of the country and wide variation in altitude make for a wide range of climate types. Summers are the warmest and wettest season in most of Argentina except in most of Patagonia where it is the driest season. Warm in the north, cool in the center and cold in the southern parts experiencing frequent frost and snow. Because southern parts of the country are moderated by the surrounding oceans, the cold is less intense and prolonged than areas at similar latitudes in the northern hemisphere. Spring and autumn are transition seasons that generally feature mild weather.
Calabozos is a Holocene caldera in central Chile's Maule Region. Part of the Chilean Andes' volcanic segment, it is considered a member of the Southern Volcanic Zone (SVZ), one of the three distinct volcanic belts of South America. This most active section of the Andes runs along central Chile's western edge, and includes more than 70 of Chile's stratovolcanoes and volcanic fields. Calabozos lies in an extremely remote area of poorly glaciated mountains.
Due to its vast size and range of altitudes, Argentina possesses a wide variety of climatic regions, ranging from the hot subtropical region in the north to the cold subantarctic in the far south. The Pampas region lies between those and featured a mild and humid climate. Many regions have different, often contrasting, microclimates. In general, Argentina has four main climate types: warm, moderate, arid, and cold in which the relief features, and the latitudinal extent of the country, determine the different varieties within the main climate types.
The Mission of Nahuel Huapi was an intermittent Jesuit mission that existed in colonial times on the shores of Nahuel Huapi Lake, northern Patagonia. The exact locations of the missions are not known but it has been suggested, based on a Christian grave finding, that the mission of the early 18th century was located in Huemul Peninsula.
