This year-round rainfall occurs because most of the region lies north of the subtropical high pressure belt even in winter, exposing it to moist easterly winds from the Atlantic Ocean throughout the year. Higher still grow the queñoa, small, crooked trees that in places extend to the timberline at 11,500 feet (3,500 metres). Argentina: facts, history, economics, geography,climate, 1. In much of Patagonia precipitation is concentrated in winter with snowfall occurring occasionally, particularly in the mountainous west and south; precipitation is more evenly distributed in the east and south. The zone begins in the Andean Northwest and extends along the eastern slopes of the Andes southward to, but not including, Tierra del Fuego. Percent possible sunshine is defined as the percentage of theoretical sunshine a place receives where theoretical sunshine is defined as the highest amount of sunshine that a place possibly receives if there is no obstruction of sunlight from coming in. climate of the country shape the inuence of climate. , Precipitation decreases from east to west, and ranges from 1,200 mm (47 in) in the northeast, to under 500 mm (20 in) in the south and west. O ne of the most salient features of the Argentine territory is its variety of climates: humid, dry, tropical heat or nival cold, through different kinds of mild climates. , It has an arid or semi-arid climate. Comprising almost the entire southern half of South America, Argentina is the world's eighth largest country, covering an area of 2.8 million square km.  The vast size, and wide range of altitudes, contribute to Argentina's diverse climate. Most other Argentine Indians were hunters and gatherers who fought the Spanish tenaciously but were eventually exterminated or driven away. Argentina possesses some of the world's tallest mountains, expansive deserts, and impressive waterfalls, with the diversity of the land ranging from wild, remote areas in southern Patagonia to the bustling metropolis of Buenos Aires in the north. Weather stations at an altitude above 1220m have not been included. Regions of Argentina Of Argentina's more than 278 million hectares of land, nearly 17.5 million hectares are established as protected, which is about 6.3% of the country's landmass. In 1999 the peninsula was designated a UNESCO World Heritage site. Argentina's climate ranges from the great heat and extensive rains of the subtropical Chaco in the north, through to the pleasant climate of the central Pampas, and the sub-Antarctic cold of the Patagonian Sea in the south.  The eastern slopes of the mountains receive between 1,000 to 1,500 mm (39 to 59 in) of precipitation a year although some places receive up to 2,500 mm (98 in) of precipitation annually owing to orographic precipitation. According to the prevailing climate, the country is divided into mild, sub-tropical and arid regions. Both factors render the region dry.  Consequently, there is a wide variety of biomes in the country, including subtropical rain forests, semi-arid and arid regions, temperate plains in the Pampas, and cold subantarctic in the south. :20 With the Andes blocking most rain bearing clouds from the Pacific Ocean, along with atmospheric circulation patterns unfavourable for rain, this results in a dry season during winter. African Continent:History, Region,,Countries.  Winters have a more uniform temperature distribution. Mendoza is Argentina’s most famous and most important wine region, home to more than 1200 wineries (known as bodegas locally) and responsible for the vast majority of all wine produced in the country.  Absolute minimum temperatures are more than −15 °C (5 °F) in coastal areas, while in the central Patagonian plateaus, they can reach below −20 °C (−4 °F).. Argentina Weather, climate and geography Weather and climate Best time to visit. Climate change in Argentina is predicted to have significant effects on the living conditions in Argentina. 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. Dataset Updated: 15-Nov-2013 16:20:30: Temperature Sites: 40,747: Monthly Mean Observations: 15,717,007: Most Recent Month: October 2013: Earliest Month: January 1701 The rich wildlife of the Chaco includes deer, peccaries, monkeys, tapirs, jaguars, pumas, ocelots, armadillos, capybaras, and agoutis. The temperate climate is interrupted by a long, narrow north-south band of semiarid to arid conditions and by tundra and polar conditions in the high Andes and in southern portions of Tierra del Fuego. Mendoza lies the heart of Argentina’s wine country. The different soils and climates in the country, offer a variety of agricultural products, adapted to the possibilities of each region. Smaller groups have also made notable contributions, however. Many regions have different, often contrasting, microclimates. Streams harbour numerous fish species, including piranhas, and snakes and other reptiles abound. , Valleys in the southern parts of the region are drier than valleys in the north due to the greater height of the Andes and the Sierras Pampeanas on the eastern slopes compared to the mountains in the north (ranging from 3,000 to 6,900 m (9,800 to 22,600 ft)), presenting a significant orographic barrier that blocks moist winds from the Atlantic and Pacific Oceans. Due to the importance of the winemaking sector in Mendoza, Argentina, the assessment of future scenarios for viticulture is of foremost relevance.  In most of Patagonia, precipitation is concentrated in the winter months with the exception of northeastern and southern areas of the region which have a more even distribution of precipitation throughout the year. , The atmospheric circulation is controlled by the two semi–permanent South Atlantic and South Pacific highs,:18 and the Chaco Low. Salta / Argentinien", "Klimatafel von La Rioja, Prov. The center of the country has a temperate climate, but it can be hot and humid in summer and cold in winter. , Annual temperatures range from 17 °C (63 °F) in the northern parts to 14 °C (57 °F) in the south. During winter, stationary fronts bring long rainy periods.  Eastern parts of Jujuy Province, Salta Province, and Tucumán Province, and northern parts of Córdoba Province and Santa Fe Province are part of the region. , The Pampas includes all of Buenos Aires Province, eastern and southern Córdoba Province, eastern La Pampa Province, and southern Santa Fe Province. For when you decide to visit, we’ve put together this brief guide to Argentina’s top five wine regions.  July temperatures range from 7 to 8 °C (45 to 47 °F). 1. Many regions have different, often contrasting, microclimates. Mendoza. The Patagonian Andes do not support a flourishing animal life: the smallest known deer, the pudu, dwells there, and wild pigs, introduced by Europeans, have multiplied. The Chaco region in the center-north, despite being relatively homogeneous in terms of precipitation and temperature, is the warmest region in Argentina, and one of the few natural areas in the world located between tropical and temperate latitudes that is not a desert.  In many places precipitation, which mostly occurs in the form of convective thunderstorms, is high during summer.  On the Patagonian plateaus, mean annual temperatures range from 8 to 10 °C (46 to 50 °F) which decreases towards the west. They were divided by the Spanish into small groups and were sent to work in Peru and the Río de la Plata area.  The high precipitation in the Andes in this region supports glaciers and permanent snowfields. Stretched over 3,700 kilometers (2,300 miles) from north to south, Argentina has a diverse range of climates, spanning from the almost tropical climate of the north, to the temperate climate of Buenos Aires and the Pampas, to the cold and windy climate of Patagonia, and finally to the subpolar climate of Tierra del Fuego.  The daily and annual range of temperatures on these plateaus is very high.  Temperatures are usually mild during the day and cold during the night. Almost half of the European immigrants in the late 19th and early 20th centuries were Italian, and about one-third were Spanish. , Patagonia is located between the subtropical high pressure belt, and the subpolar low pressure zone, meaning it is exposed to westerly winds that are strong, since south of 40o S, there is little land to block these winds. Buenos Aires, located on the northern edge of the Pampas, has a climate similar to that of cities in the southeastern United States, with hot, humid summers and cool, mild winters.  During winter, both the South Pacific and South Atlantic highs move to the north, while the Subpolar Low strengthens, which, when combined with higher ocean temperatures than the surrounding land, results in higher precipitation during this time of the year. :16, The Cuyo region includes the provinces of Mendoza, San Juan, and San Luis. The indigenous, plantlike ombu tree (Phytolacca dioica) is prized for the shade it provides but is of no commercial value.
