Climate of Argentina : ウィキペディア英語版 | Climate of Argentina
The climate of Argentina is a complex subject: the country's vast size and considerable variation in altitude make for a wide range of climate types. Many regions have different, often contrasting, microclimates. In general, northern parts of the country are characterized by hot, humid, rainy summers and mild winters with periodic droughts. The center of the country has hot summers with occasional tornadoes and thunderstorms, and cool, dry winters. The southern part of the country has a dry climate with warm summers and cold winters. High elevations at all latitudes experience cooler conditions, and the mountainous zones can see heavy snowfall. Argentina has four seasons: winter (June–August), spring (September–November), summer (December–February) and autumn (March–May), all featuring different weather conditions. The hottest and coldest temperature extremes recorded in South America have occurred in Argentina.〔(【引用サイトリンク】url= http://wmo.asu.edu/#continental )〕 The highest recorded temperature is in Rivadavia, Salta Province, on December 11, 1905, while the lowest temperature recorded is at Sarmiento, Chubut, on June 1, 1907.〔 The geographic and geomorphic characteristics of Argentina tend to create extreme weather conditions, often leading to natural disasters that negatively impact the country both economically and socially. The Pampas, where many of the large cities are located, has a flat topography and poor water drainage, making it vulnerable to flooding. Severe storms can lead to tornadoes, damaging hail, storm surges, and high winds, causing extensive damage to houses and infrastructure, displacing thousands of people and causing significant loss of life. Extreme temperature events such as heat waves and cold waves impact rural and urban areas by negatively impacting agriculture, one of the main economic activities of the country, and by increasing energy demand, which can lead to energy shortages. Argentina is vulnerable and will be significantly impacted by climate change. Temperatures have increased in the last century while the observed changes in precipitation are variable, with some areas receiving more and other areas receiving less. These changes have impacted river flow, increased the frequency of extreme weather events, and led to the retreat of glaciers. Based on the projections for both precipitation and temperatures, these climatic events are likely to increase in severity and create new problems associated with climate change in the country. ==Seasons==
