Buenos Aires, officially the Buenos Aires Province, is the largest and most populous Argentine province. It takes its name from the city of Buenos Aires, the capital of the country, which used to be part of the province and the province's capital until it was federalized in 1880. Since then, in spite of bearing the same name, the province does not include Buenos Aires proper, though it does include all other parts of the Greater Buenos Aires metropolitan area. The capital of the province is the city of La Plata, founded in 1882.
The Pampas are fertile South American low grasslands that cover more than 1,200,000 square kilometres (460,000 sq mi) and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos, and Córdoba; all of Uruguay; and Brazil's southernmost state, Rio Grande do Sul. The vast plains are a natural region, interrupted only by the low Ventana and Tandil hills, near Bahía Blanca and Tandil (Argentina), with a height of 1,300 m (4,265 ft) and 500 m (1,640 ft), respectively.
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. According to the Köppen climate classification, Tropical climates are defined by a monthly average temperature of 18 °C (64.4 °F) or higher in the coolest month; or in general they simply create hot sensation all of time. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm but may have seasonal dryness to varying degrees. There are normally only two seasons in tropical climates, a wet (rainy/monsoon) season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense in these climates. There are three basic types of tropical climates within the tropical climate group: tropical rainforest climate (Af), tropical monsoon climate (Am) and tropical wet and dry climate or tropical savannah, which are classified and distinguished by the precipitation and the precipitation levels of the driest month in those regions.
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification.
Tucumán is the most densely populated, and the second-smallest by land area, of the provinces of Argentina.
Neuquén is a province of Argentina, located in the west of the country, at the northern end of Patagonia. It borders Mendoza Province to the north, Rio Negro Province to the southeast, and Chile to the west. It also meets La Pampa Province at its northeast corner.
La Pampa is a sparsely populated province of Argentina, located in the Pampas in the center of the country. Neighboring provinces are from the north clockwise San Luis, Córdoba, Buenos Aires, Río Negro, Neuquén and Mendoza.
Santiago del Estero is the capital of Santiago del Estero Province in northern Argentina. It has a population of 252,192 inhabitants, making it the twelfth largest city in the country, with a surface area of 2,116 km2. It lies on the Dulce River and on National Route 9, at a distance of 1,042 km north-northwest from Buenos Aires. Estimated to be 455 years old, Santiago del Estero was the first city founded by Spanish settlers in the territory that is now Argentina. As such, it is nicknamed "Madre de Ciudades". Similarly, it has been officially declared the "mother of cities and cradle of folklore."
Junín is a city in the province of Buenos Aires, Argentina, and administrative seat of the partido of Junín. It has a population of 85,420 and is located 260 km (162 mi) west of the city of Buenos Aires. It is mostly known for being the hometown of former first lady of Argentina Eva Perón.
Pehuajó is a city in the Pehuajó Partido in the province of Buenos Aires, Argentina. The partido has about 38,400 inhabitants as per the 2001 census [INDEC]. The name of this relatively small city is well known in Argentina because of María Elena Walsh's song Manuelita, about an adventurous turtle (tortoise); a dilapidated concrete statue of María Elena Walsh's Manuelita lies just outside the city, beside Ruta Nacional 5.
The Humid Pampas is an extensive ecoregion of flat, fertile grassland of loessic origin in Argentina. It has a precipitation average of 900 mm per year, in contrast with the Dry Pampas to the west, which average less than 700 mm.
The Paraná Delta is the delta of the Paraná River in Argentina and it consists of several islands known as the Islas del Paraná. The Paraná flows north–south and becomes an alluvial basin between the Argentine provinces of Entre Ríos, Santa Fe and Buenos Aires then emptying into the Río de la Plata.
Mercedes Partido is a partido in the eastern part of Buenos Aires Province in Argentina.
Monte Partido is a partido in the eastern part of Buenos Aires Province in Argentina.
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.
A humid subtropical climate is a zone of climate characterized by hot and humid summers, and cool to mild winters. These climates normally lie on the southeast side of all continents, generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates. It is also known as warm temperate climate in some climate classifications.
Córdoba is a province of Argentina, located in the center of the country. Its neighboring provinces are Santiago del Estero, Santa Fe, Buenos Aires, La Pampa, San Luis, La Rioja, and Catamarca. Together with Santa Fe and Entre Ríos, the province is part of the economic and political association known as the Center Region.
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.
Buenos Aires, the capital of Argentina, has a temperate climate, which is classified as a humid subtropical climate (Cfa) under the Köppen climate classification with four distinct seasons. Summers are hot and humid with frequent thunderstorms while winters are cool and drier with frosts that occurs on average twice per year. Spring and fall are transition seasons characterized by changeable weather. At the central observatory, the highest temperature recorded is 43.3 °C (109.9 °F), and the lowest temperature recorded is −5.4 °C (22.3 °F).
The Espinal (NT0801) is an ecoregion of dry, thorny forest, savanna and steppe in Argentina. It has been extensively modified by large scale cattle ranching, but remnants of the original flora remain. It is threatened by the advance of the irrigation-based agricultural frontier.
