Covering a large area, there are a surprising amount of micro-climates and different altitudes that result in a variety of wines. It is bounded, approximately, by the Patagonian Andes, the Colorado River (except where the region extends north of the river into the Andean borderlands), the … Patagonia (Spanish pronunciation: [pataˈɣonja]) is a sparsely populated region at the southern end of South America, shared by Argentina and Chile.The region comprises the southern section of the Andes Mountains, lakes, fjords, and glaciers in the west and deserts, tablelands and steppes to the east. Climate: mostly temperate; arid in southeast; subantarctic in southwest: Location: Southern South America, bordering the South Atlantic Ocean, between Chile and Uruguay: Geographic coordinates: 34 00 S, 64 00 W: Comparative Area: slightly less than three-tenths the size of … [108] Autumn and spring bring periods of very rainy weather followed by dry, mild stretches. Elephant seals and Magellan penguins live along Argentina's southern coast. A local phenomenon near the southern tip of the continent is species of parrots and other birds more commonly associated with the tropics than with Patagonia. [60][61], 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. [59], In the valleys in the south in La Rioja and Catamarca Provinces, along with the southwest parts of Santiago del Estero Province, temperatures during the summer are very high averaging 26 °C (79 °F) in January, while winters are mild averaging 12 °C (54 °F). Palm savanna in the eastern Chaco Central, near Formosa, northeastern Argentina. [121] During summer, the South Pacific High migrates southward, preventing the passage of fronts, and cyclones that can cause precipitation to occur, resulting in lower precipitation during this time of the year. The only other area of obvious interest to export markets is the high-altitude vineyards around Cafayate in the province of Salta in the far north of the country.

Accessibility links. This is particularly true in Patagonia, where windblown dust creates a continuous haze that considerably reduces visibility. Some provinces span more than one of these regions. [121] Northern areas are sunnier (50% possible sunshine)[note 5] than the southern parts of the region such as western Santa Cruz and Tierra del Fuego Provinces (less than 40% possible sunshine). [87] Since this region has a wide range of altitudes ranging from 500 m (1,600 ft) to nearly 7,000 m (23,000 ft), temperatures can vary widely with altitude. The different soils and climates in the country, offer a variety of agricultural products, adapted to the possibilities of each region. The influence of the Andes, in conjunction with general circulation patterns, generates one of the strongest precipitation gradients (rate of change in mean annual precipitation in relation to a particular location) in the world, decreasing rapidly to the east. [116][117] Being located between the semipermanent South Pacific and the South Atlantic Highs at around 30oS, and the Subpolar Low at around 60o S, the movement of the high and low pressure systems, along with ocean currents, determine the precipitation pattern. Many regions have different, often contrasting, microclimates. [97][98][99] The weather in the Pampas is variable due to the contrasting air masses and frontal storms that impact the region. [119] The annual range of temperatures in Patagonia is lower than in areas in the Northern Hemisphere at the same latitude owing to the maritime influences of the sea. [62]:28[71] During winter, cold fronts from the south bringing cold Antarctic air can cause temperatures to fall between −8 to −14 °C (18 to 7 °F) with severe frosts. Vegetation on the mostly exposed soil of the puna consists of dwarf shrubs and tough grasses, notably bunchgrass; these and other plants in the region are coloured almost as brown as the ground itself. Low scrub vegetation and green grass steppe alternate south of Comodoro Rivadavia to the tip of the continent. [99] Occasionally, tropical air masses from the north may move southward, providing relief from the cool, damp temperatures. [125] Much of northwestern Patagonia in the Andes, corresponding to the northern parts of the Bosque Andino Patagónico region, receives abundant precipitation in winter with occasional droughts in summer, allowing it to support forests with dense coverage. [87] In contrast, winters are dry and cold and average around 7–8 hours of sunshine per day. [53][54]:29 There is great variation in precipitation both seasonally and annually. According to the prevailing climate, the country is divided into mild, sub-tropical and arid regions. Antarctic beech and needle-leaved trees mixed with araucaria are common. The French grape variety Malbec has its New World home in the vineyards of Mendoza, producing red wines of great concentration and intensity. [20][23]:31Precipitation is slightly higher in summer than in winter, and generally decreases from east to west and from north to south.

[20] whose main features are high temperatures and abundant rainfall throughout the year. [121] In Tierra del Fuego, thunderstorms are non-existent. [119] Thunderstorms are infrequent in the region, occurring an average of 5 days per year, only during summer. [66][86] The average temperature in January is 24 °C (75 °F) in most of the region. Precipitation here is about 1040 mm | 40.9 inch per year. The new government has mainly focused its policy efforts on addressing the economic crisis that pre-dates the pandemic but has been exacerbated by it, putting further climate … [24] Summers are hot and humid while winters are mild. [23]:85, The Chaco region is the hottest in Argentina, with a mean annual temperature of 23 °C (73 °F). [103] Generally, frost arrives in early April in the southernmost areas, and in late May in the north and ends by mid-September – although the dates of the first and last frosts can vary from year to year. [9] The western part has a pronounced dry winter season while the eastern parts have a slightly drier season. The vines were brought by Spanish settlers and the Argentina wine regions were soon established along the foots of the Andes. [60][61] In the Yungas jungle to the east, the climate is hot and humid with temperatures that vary significantly based on latitude and altitude. [85] Summers in the region are hot and generally very sunny, averaging as much as 10 hours of sunshine per day. Due to the importance of the winemaking sector in Mendoza, Argentina, the assessment of future scenarios for viticulture is of foremost relevance. [3][4] Argentina possesses a wide variety of climatic regions ranging from subtropical in the north to subantarctic in the far south. [123][121] South of 52oS, the Andes are lower in elevation, reducing the rain shadow effect in Tierra del Fuego Province, allowing forests to thrive on the Atlantic coast. [18][19], The region of Mesopotamia includes the provinces of Misiones, Entre Ríos and Corrientes. Wildlife in the region includes now rare guanacos and rheas, as well as eagles and herons, the Patagonian cavy (mará) and other burrowing rodents, mountain cats and pumas, and various poisonous snakes. As immigration slowed later in the 20th century, the proportion of foreign-born Argentines dropped. Topographie Argentiniens. › Overview: Climate in Argentina › Duration of daylight and sunshine in Argentina Home to more than 1,200 wineries, Mendoza produces nearly two-thirds of all of Argentina’s wine. Vegetation includes species of mimosa and acacia, and there is a smattering of cactus. [121] The high precipitation in the Andes in this region supports glaciers and permanent snowfields. [56][67] In contrast, during a La Niña year, there is enhanced easterly moisture transport, resulting in a more intense rainy season. Misiones is one of the warmest region in Argentina with an average daily high temperature of 27 degrees centigrade. [121] In general, the passage of cold fronts is more common in the south than in the north, and occurs more in winter than in summer. 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. The climate in Argentina is very varied. [103] Autumn arrives in March and brings periods of mild daytime temperatures and cool nights. [40][41] During the entire year, the South Pacific High influences the climate by bringing cold, moist air masses originating in Patagonia[42] leading to cold temperatures and frost, particularly during winter. [100] Temperatures are usually mild during the day and cold during the night. In Buenos Aires, the average annual temperature is 16.8 °C | 62.2 °F. [39]:486 Precipitation and temperature are relatively homogeneous throughout the region. Penguins and seals frequent coastal areas, especially in the south. In fact, it is home to mountainous, rugged topography, subtropical southern regions, moist grasslands, fertile plains, and dense forestry as well. Substantial numbers also came from France, Poland, Russia, Germany, and Great Britain. [82][83][84] In the Cuyo region, annual precipitation is highly variable from year to year and appears to follow a cycle between dry and wet years in periods of about 2, 4–5, 6–8, and 16–22 years. [9][10] Argentina is best divided into six distinct regions reflecting the climatic conditions of the country as a whole. Paraná pines appear at higher elevations. Travelling is one of the ways we exercise our hobbies. [121] Northeastern areas, along with southern parts of the region, are influenced by air masses from the Atlantic Ocean, resulting in precipitation being more evenly distributed throughout the year. [109] Dull, grey, and damp weather characterize winters in the Pampas. Regions of Argentina. [9] However, despite the diversity of biomes, about two-thirds of Argentina is arid or semi-arid.

The regions are as follows: Andean Northwest, Chaco, Cuyo, Mesopotamia, Pampas, Patagonia, and Tierra del Fuego. Nearly unattractive for tourists are the cold months from May to September. [20][21]:12[25] The mean January temperature throughout most of the region is 25 °C (77 °F) except in the uplands of Misiones Province where they are lower owing to its higher elevation. The boundary between the Dry and Humid Pampas lies approximately along longitude 64° W. Knee-high grasses are found in the most humid areas, whereas to the north, west, and south, where precipitation decreases, tougher grasses give way to the monte of the Dry Pampa. [39]:486 The general atmospheric circulation influences the climate of the region, primarily by two permanent high pressure systems – the South Pacific High and the South Atlantic High – and a low pressure system that develops over northeast Argentina called the Chaco Low. The is a great deal of rainfall in Buenos Aires, even in the driest month. [9][64] This results in the Puna region having a water deficit in all months. [54]:18[55] During the winter months, the intertropical convergence zone, the South Pacific, and the South Atlantic highs move northward while the Chaco Low weakens, all of which results in the suppression of rain during the winter.
