The Climate of Colombia is characterized for being tropical and isothermal as a result of its geographical location near the Equator presenting variations within five natural regions and depending on the altitude, temperature, humidity, winds and rainfall. Each region maintains an average temperature throughout the year only presenting variables determined by precipitation during a rainy season caused by the Intertropical Convergence Zone. [1] [2]
The climates in Colombia are characterized for having tropical rainforests, savannas, steppes, deserts and mountain climate, mountain climate further divided into tierra caliente (hot land) tierra templada (temperate land) tierra fría (cold land), tierra helada (frozen land) and Páramo. [3] Sometimes the weather of Colombia is altered by the seasons in northern hemisphere, for example, from March to June, the weather is mild Spring, from June to August the weather is hot Summer, From September to December the weather is cool Autumn, and from December to March the weather is cold Winter. This happens very rarely, and it is usually a slight difference.
The tropical rainforest climate is characterized by hot and high humidity climate along with heavy rainfall mostly present in the jungles of the Catatumbo, the Amazon river basin the central region of the Magdalena River, the Pacific coast, the paru and others.
Mountain climate is one of the unique features of the Andes, the Sierra Nevada de Santa Marta and other high altitude reliefs where climate is determined by elevation. (Spanish: Pisos termicos), a classification used in some countries but with variations in the classification of each floor. [4]
The warm altitudinal zone oscillates between sea level and 1,000 meters (3,281 ft) above sea level with a temperature over 24 °C (75.2 °F). Climate in this step is characterized for its similarities with the equatorial and tropical plains, heavy rains and high temperatures. Temperatures can reach over 37.8 °C (100.0 °F) as it is the case of the Magdalena river valley, which has many areas with jungles. This altitudinal zone is present in the cities like Santa Marta, Neiva, Cali, and Cúcuta.
Between 1,000 and 2,000 meters (3,281 and 6,562 ft) above sea level the temperature drops oscillating between 17 and 22 °C (62.6 and 71.6 °F) defining it as a temperate climate. Rainfall becomes variable at 1,700 meters (5,577 ft) above sea level and rains between 2,000 and 2,500 mm (78.7 and 98.4 in). This climate is a characteristic in the cities like Pereira, Armenia, Ibagué, Popayán, and Medellín.
The cold climate is present between 2,000 and 3,000 meters (6,562 and 9,843 ft) above sea level and is characterized for having Andean or cloud forests. This altitudinal zone is characterized for presenting an average temperature ranging between 10 and 17 °C (50.0 and 62.6 °F) while rainfall reaches a yearly average of 2,000 mm (78.7 in). The Colombian capital city Bogotá is located within this altitudinal zone. Other cities like San Juan de Pasto and Tunja are in this location.
The Páramo climate is present between 3,000 and 4,000 meters (9,843 and 13,123 ft) above sea level and the temperature is lower than 10 °C (50 °F) with icy winds, rare rainfall but frequent snowfall. Colombia has one of the largest páramo areas in the world; the Sumapaz Páramo located in central Colombia, over the Andean Cordillera Oriental branch. In Colombia páramos are further classified as subpáramo, páramo and superpáramo. Most of the rivers in Colombia are born here since páramos tend to hold water from precipitations and deglaciations coming from the peaks. [5]
The glaciers in Colombia are located at 4,000 meters (13,123 ft) above sea level and up and with average temperatures ranging between 10 °C (50 °F) and less. Glaciers in Colombia began retreating in the 20th century due to global warming and are in danger of disappearing, if this occurs water supply would be scarce in the near future. [6] [7] Most of the glaciers are located in the Andes mountains and are inhabited by very few living species due to its severe weather. [8]
The Republic of Colombia is situated largely in the north-west of South America, with some territories falling within the boundaries of Central America. It is bordered to the north-west by Panama; to the east by Brazil and Venezuela; to the south by Ecuador and Peru; and it shares maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, the Dominican Republic, and Haiti.
The geography of Bolivia includes the Eastern Andes Mountain Range which bisects Bolivia roughly from north to south. To the east of that mountain chain are lowland plains of the Amazon Basin, and to the west is the Altiplano which is a highland plateau where Lake Titicaca is located. Bolivia's geography has features similar to those of Peru which abuts Bolivia's northwest border; like Bolivia, Peru is bisected from north to south by the Eastern Andes Mountains, and these two countries share Lake Titicaca which is the highest navigable lake on Earth. Unlike Peru, however, Bolivia is one of the two landlocked countries in South America, the other being Paraguay which is located along Bolivia's southeast border.
In Latin America, tierra fría are mountain locations where high elevation results in a markedly cooler climate than that encountered in the lowlands at a comparable latitude. The combination of low latitude and high altitude — typically between approximately 2,000 m and 3,500 m in locations within 10° of the equator — produces a climate that falls into the same category as many oceanic climates found along the west coasts of the continents within the temperate zones — mild temperatures all year round, with monthly averages ranging from about 10°C (50°F) in the coldest months to about 18°C (64.4°F) in the warmest months. Common crops grown in the tierra fría are potatoes, wheat, barley, oats, corn, and rye.
Tierra Helada, also known as Tierra Nevada, is a term used in Latin America to refer to the highest places found within the Andes mountains.
Sangay is an active stratovolcano in central Ecuador. It exhibits mostly strombolian activity. Geologically, Sangay marks the southern boundary of the Northern Volcanic Zone, and its position straddling two major pieces of crust accounts for its high level of activity. Sangay's approximately 500,000-year-old history is one of instability; two previous versions of the mountain were destroyed in massive flank collapses, evidence of which still litters its surroundings today.
Páramo may refer to a variety of alpine tundra ecosystems located in the Andes Mountain Range, South America. Some ecologists describe the páramo broadly as "all high, tropical, montane vegetation above the continuous timberline". A narrower term classifies the páramo according to its regional placement in the northern Andes of South America and adjacent southern Central America. The páramo is the ecosystem of the regions above the continuous forest line, yet below the permanent snowline. It is a "Neotropical high mountain biome with a vegetation composed mainly of giant rosette plants, shrubs and grasses". According to scientists, páramos may be "evolutionary hot spots", that meaning that it's among the fastest evolving regions on Earth.
The Sierra Nevada de Santa Marta is an isolated mountain range in northern Colombia, separate from the Andes range that runs through the north of the country. Reaching an elevation of 5,700 m (18,700 ft) just 42 km (26 mi) from the Caribbean coast, the Sierra Nevada is the highest coastal range in the tropics, and one of the highest coastal ranges in the world, being 250 metres (820 ft) shorter than the Saint Elias Mountains in Canada. The Sierra Nevada encompasses about 17,000 km2 (6,600 sq mi) and serves as the source of 36 rivers. The range is in the Departments of Magdalena, Cesar and La Guajira.
The Yungas is a bioregion of a narrow band of forest along the eastern slope of the Andes Mountains from Peru and Bolivia, and extends into Northwest Argentina at the slope of the Andes pre-cordillera. It is a transitional zone between the Andean highlands and the eastern forests. Like the surrounding areas, the Yungas belong to the Neotropical realm; the climate is rainy, humid, and warm.
The Chala or "Coast" is one of the eight natural regions in Peru. It is formed by all the western lands that arise from sea level up to the height of 500 meters. The coastal desert of Peru is largely devoid of vegetation but a unique fog and mist-fed ecosystem called Lomas is scattered among hills near the Pacific coast as elevations up to 1,000 metres (3,300 ft).
When the Spanish arrived, they divided Peru into three main regions: the coastal region, that is bounded by the Pacific Ocean; the highlands, that is located on the Andean Heights, and the jungle, that is located on the Amazonian Jungle. But Javier Pulgar Vidal, a geographer who studied the biogeographic reality of the Peruvian territory for a long time, proposed the creation of eight Natural Regions. In 1941, he presented his thesis "Las Ocho Regiones Naturales del Perú" at the III General Assembly of the Pan-American Institute of Geography and History.
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 Tropical Andes is northern of the three climate-delineated parts of the Andes, the others being the Dry Andes and the Wet Andes. The Tropical Andes' area spans 1,542,644 km2 (595,618 sq mi).
Because of its natural structure, Colombia can be divided into six distinct natural regions. These consist of the Andean Region, covering the three branches of the Andes mountains found in Colombia; the Caribbean Region, covering the area adjacent to the Caribbean Sea; the Pacific Region adjacent to the Pacific Ocean; the Orinoquía Region, part of the Llanos plains mainly in the Orinoco river basin along the border with Venezuela; the Amazon Region, part of the Amazon rainforest; and finally the Insular Region, comprising the islands in both the Atlantic and Pacific Oceans. Colombia is located in South America.
Altitudinal zonation in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions. Temperature, humidity, soil composition, and solar radiation are important factors in determining altitudinal zones, which consequently support different vegetation and animal species. Altitudinal zonation was first hypothesized by geographer Alexander von Humboldt who noticed that temperature drops with increasing elevation. Zonation also occurs in intertidal and marine environments, as well as on shorelines and in wetlands. Scientist C. Hart Merriam observed that changes in vegetation and animals in altitudinal zones map onto changes expected with increased latitude in his concept of life zones. Today, altitudinal zonation represents a core concept in mountain research.
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.
Farallones de Cali is a cluster of mountains in the West Andes of Colombia. It is located west of the city of Cali and gives rise to many of the rivers that provide water and electricity to Cali. The PNN Farallones de Cali encompasses 150,000 ha (580 sq mi) in the mountains as well as much of the Pacific slope and is an area of very high biodiversity. The average temperature ranges from 25 °C (77 °F) in the tropical foothills to 5 °C (41 °F) in the páramo. In this territory are located the district of Pichinde, Andes and Leonera, and two villages Penas Blancas and Lomas de la Cajita.
Sumapaz Páramo is a large páramo ecosystem located in the Altiplano Cundiboyacense mountain range, considered the largest páramo ecosystem in the world. It was declared a National Park of Colombia in 1977 because of its importance as a biodiversity hotspot and main source of water for the most densely populated area of the country, the Bogotá savanna.
The Northern Andean páramo (NT1006) is an ecoregion containing páramo vegetation above the treeline in the Andes of Colombia and Ecuador. In the past, when the climate was cooler, the treeline and the páramo units were lower and the units were connected. During the present warmer Holocene epoch the páramos have migrated uphill, shrinking and becoming isolated. They contain many rare or endangered species, some of them restricted to a narrow area of one mountain or mountain range. The ecoregion is relatively well preserved, but faces threats from over-grazing and farming.
The Santa Marta páramo (NT1007) is an ecoregion containing páramo vegetation above the treeline in the Sierra Nevada de Santa Marta mountain range on the Caribbean coast of Colombia. The isolated position of the range has allowed unique species to evolve. Some are related to those found in Central America and the Caribbean coastal areas, and some to species from the Andes. The habitat is relatively stable, but has been drastically changed from the original by long-term human activity.
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.
