context_page_description: 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. Lying between those is the Pampas region, featuring 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.
  Northern parts of the country are characterized by hot, humid summers with mild, drier winters, and highly seasonal precipitation. Mesopotamia, located in northeast Argentina, has a subtropical climate with no dry season and is characterized by high temperatures and abundant rainfall because of exposure to moist easterly winds from the Atlantic Ocean throughout the year.
context_section_description: The Pampas includes all of Buenos Aires Province, eastern and southern Córdoba Province, eastern La Pampa Province, and southern Santa Fe Province. It is subdivided into two parts: the humid Pampas to the east, and the dry/semi–arid Pampas to the west.
  This region's land is appropriate for agricultural and livestock activities. It is mostly a flat area, interrupted only by the Tandilia and Ventana hills in its southern portion. The climate of the Pampas is temperate and humid with no dry season, featuring hot summers and mild winters (Cfa/Cfb according to the Köppen climate classification). The weather in the Pampas is variable due to the contrasting air masses and frontal storms that impact the region. Maritime polar air from the south produces the cool pampero winds, while warm humid tropical air from the north produces sultry nortes – a gentle wind usually from the northeast formed by trade winds, and the South Atlantic High that brings cloudy, hot, and humid weather and is responsible for bringing heat waves. The Pampas are influenced by the El Niño–Southern Oscillation which is responsible for variations in annual precipitation. An El Niño year often leads to higher precipitation, while a La Niña year leads to lower precipitation. The Pampas are moderately sunny, ranging from an average of 4–5 hours of sunshine per day during the winter months to 8–9 hours in summer.
