Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. Tropical climates are defined by a monthly average temperature of 18 °C (64.4 °F) or higher in the coolest month, and feature hot temperatures all year-round. 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 season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense in these climates.
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 in 1954 and 1961, which is thus sometimes called the Köppen–Geiger climate classification.
La Mesopotamia or Región Mesopotámica is the humid and verdant area of northeast Argentina, comprising the provinces of Misiones, Entre Ríos, and Corrientes. The landscape and its characteristics are dominated by two rivers: the Paraná and the Uruguay.
Daniel Campos is a province in the north-western parts of the Bolivian Potosí Department. It is named after the poet Daniel Campos who originated from this area. The capital of the province is Llica.
The Argentine Northwest is a geographic and historical region of Argentina composed of the provinces of Catamarca, Jujuy, La Rioja, Salta, Santiago del Estero and Tucumán.
Climate of Peru describes the diverse climates of this large South American country with an area of 1,285,216 km2 (496,225 sq mi). Peru is located entirely in the tropics but features desert and mountain climates as well as tropical rainforests. Elevations above sea level in the country range from −37 to 6,778 m and precipitation ranges from less than 20 mm (0.79 in) annually to more than 8,000 mm (310 in). There are three main climatic regions: the Pacific Ocean coast is one of the driest deserts in the world but with some unique features; the high Andes mountains have a variety of microclimates depending on elevation and exposure and with temperatures and precipitation from temperate to polar and wet to dry; and the Amazon basin has tropical climates, mostly with abundant precipitation, along with sub-tropical climates in elevations above 1,550 m (5,090 ft).
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.
Vietnam has a monsoon-influenced climate typical of that of mainland Southeast Asia. The diverse topography, long latitude, and influences from the South China Sea lead to climatic conditions varying significantly between regions. The northern region experiences a monsoonal and temperate climate (Cfa) with four distinct seasons with winters typically dry and summers ranging from hot to mild. In more southern areas, the climate is tropical monsoon (Aw) with only two seasons. In addition, a temperate climate exists in mountainous areas, which are found in Sa Pa and Da Lat, while a more continental climate exists in Lai Châu Province and Sơn La Province.
The Climate of Venezuela is characterized for being tropical and megathermal as a result of its geographical location near the Equator, but because of the topography and the dominant wind direction, several climatic types occur which can be the same as found in temperate latitudes, and even polar regions. Latitude exerts little influence on the Venezuelan While the coastal cities of Maracaibo, Barcelona, Porlamar and Maiquetia can get extremely hot, cities located at valleys such as Mérida, Caracas, Los Teques and San Cristobal have cooler climates, and the highest towns of Mucuchies and Apartaderos have cold (tundra) climates.
Ouroun is a small town and commune in the Cercle of Bougouni in the Sikasso Region of southern Mali. In 1998 the commune had a population of 3,947.
An area of tropical monsoon climate is a tropical climate sub-type that corresponds to the Köppen climate classification category Am. Tropical monsoon climates have monthly mean temperatures above 18 °C (64 °F) in every month of the year and a dry season. The tropical monsoon climate is the intermediate climate between the wet Af and the drier Aw.
Achiri is a location in the La Paz Department in Bolivia. In 2010 it had an estimated population of 817.
Cañaviri is a small town in Bolivia. In 2010 it had an estimated population of 992.
Cotagaita is a small town in Bolivia. In 2009 it had an estimated population of 1904.
Patamanta is a small town in Bolivia. It is the second largest town in the district of Pucarani in the province of Los Andes, and is located on the right bank of an inlet towards Lake Titicaca. The village is located on the Altiplano. It lies on the plateau between the Andean mountain ranges of the Cordillera Occidental in the west and the Cordillera Central in the east. Due to the historical population development, the region has a high proportion of Aymara people, with 96.7% of the population speaking the Aymara language. The population was 691 in 1992, increasing to 745 in 2001, and then 857 in 2012.
Puerto Rico is a small town in Pando, northern Bolivia, with an associated airport. It is located in the Manuripi-Heath Amazonian Wildlife National Reserve. Founded on May 18, 1890, it was the first departamental capital, before Cobija. It is located at the Confluence of the Manuripi and Tahuamanu Rivers. Every year, in the month of June, the International Recreational Fishing Championship of Puerto Rico takes place at the river confluence, where the two rivers combine to form the river the River Orthon. This river then flows 410 km before it converges with the River Beni.
Toledo (Oruro) is a small town in Bolivia. Toledo is the administrative seat of Saucarí Province, as well as that of Toledo Municipality. The town lies at an elevation of 3,715 metres (12,188 ft) between Río Laq'a Jawira in the west and Río Vinto Jahuira in the east, both of which drain into Lake Poopó.
The climate of Seoul features a humid continental climate with dry winter, called "Dwa" in the Köppen climate classification, with four highly distinct seasons. In summer the influence of the North Pacific high-pressure system brings hot, humid weather with temperatures soaring as high as 35 °C (95 °F) on occasion. In winter the city is topographically influenced by expanding Siberian High-pressure zones and prevailing west winds, temperatures dropping almost as low as -20 °C (-4 °F) in severe cold waves. The bitterly cold days are commonly known to come in three-day cycles regulated by rising and falling pressure systems. The most pleasant seasons for most people in the city are spring and autumn, when azure skies and comfortable temperatures are typical. Most of Seoul's precipitation falls in the summer monsoon period between June and September, as a part of East Asian monsoon season.
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.
The highland temperate climates are a temperate climate sub-type, although located in tropical zone, isothermal and with characteristics different from others temperate climates like oceanic or mediterranean where they are often are included without proper differentiation.
