Due to the northward migration of the South Pacific High, more frontal systems can pass through, allowing for more precipitation to occur. Forests grow along the eastern border of the puna region southward to the colder Andean zones, covering many slopes in this part of the mountains. Argentina Climatic Map page, view Argentina political, physical, country maps, satellite images photos and where is Argentina location in World map. Cold fronts that move northward from Patagonia, chiefly in July, bring occasional frosts and snow to the Pampas and Mesopotamia. More like neighboring Bolivia and Peru in terms of culture, the Northwest region of Argentina is worlds away from the European stylings of Buenos Aires. Discover (and save!) Argentina Wine Regions.  Eastern areas are more strongly influenced by maritime climate than western areas, leading to a smaller thermal amplitude (difference between average high and average low temperatures). In total, Argentina is home to nearly 300 protected areas, which include eleven internationally significant wetlands and ten different biosphere reserves.  By contrast, the western parts of the region have a negative water balance (the potential evapotranspiration exceeds the precipitation) owing to lower precipitation.  Further eastward, in San Luis Province, mean summer rainfall averages around 500 mm (20 in) and can exceed 700 mm (28 in) in some areas. The western Gran Chaco has growths of thorn forest dominated by algaroba (carob trees) in the drier and often saline zones. Rosario is a city with a significant rainfall. :28 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. The disputed Falkland Islands is a United Kingdom Overseas Territory, but is claimed by Argentina.  Winters are drier in most places due to weaker easterly winds, and stronger southerly winds, which prevent moist air from coming in.  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).  Summer rains are intense, and torrential rain is common, occasionally causing floods and soil erosion. The highest Andean peaks have permanent snow and ice cover. :18 These cold fronts are responsible for producing precipitation during summer.  As a result, the Andes create an extensive rain-shadow in much of Argentine Patagonia, causing most of the region to be arid. Back to overview: Argentina Even in the driest month there is a lot of rain. :17 The southeast parts of the Puna region are very arid receiving an average of 50 mm (2 in), while in the northeastern area, average annual precipitation ranges from 300 to 400 mm (12 to 16 in).  The southernmost islands receive some of the lowest average annual sunshine hours in the world.  However, all claims are suspended by the Antarctic Treaty System, of which Argentina is a founding signatory and permanent consulting member. Argentinien hat eine Fläche von circa 2,8 Millionen km² und ist damit der zweitgrößte Staat Südamerikas. Most of the arid region is subjected to strong winds that carry abrasive sand and dust. 7 August 2020. Both factors render the region dry. In the Humid Pampa the rainfall varies from 39 inches (990 mm) in the east to 20 inches (500 mm) in areas near the Andes—about the minimum needed for nonirrigated crops.  In general, most of the region has a temperate climate, with higher altitude valleys having a more milder climate. European descendants were in the minority.  However, such cold fronts are brief, and are less intense than in areas further south or at higher altitudes.  The north–south orientation of the mountains, which increase in altitude to the west, and a discontinuous topography, creates valleys with regions of relatively high orographic precipitation in the west and drier regions in east.  The weather in the Pampas is variable due to the contrasting air masses and frontal storms that impact the region.  The temperate valleys have a temperate climate, with mild summers, and dry and cool winters with regular frosts. The Indians and mestizos were pushed aside (mainly to the Andean provinces) or absorbed, and the blacks and mulattos disappeared, apparently also absorbed into the dominant population.  Towards the south, where land masses are narrow, the Pacific Ocean influences coastal areas in addition to the Atlantic Ocean, ensuring that the cold is neither prolonged nor intense. In the colonial period, though, the Spanish explorers and settlers encountered a number of native peoples. Vegetation includes species of mimosa and acacia, and there is a smattering of cactus. Climate change in Argentina is predicted to have significant effects on the living conditions in Argentina.  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. Precipitation here is about 1040 mm | 40.9 inch per year. Aerial views of the Pampas, east-central Argentina.
