Equatorial Rainforest Climate is generally found near the equator. This climate is characterised by a lot of sunshine throughout the year which leads to high temperatures. Because of this, the region does not experience winters. In fact, there isn't much of a difference in temperature between the seasons and throughout the hours of the day. Throughout the year, the temperature remains consistent. The region's mean monthly and annual temperatures are both about 27 degrees Celsius. This article will explain to you about Equatorial Rainforest Climate which will be helpful in preparing Geography for the UPSC Civil service exam.

Equatorial Rainforest Climate- Distribution

• Equatorial Rainforest Climate is distributed in and around the equator in both hemispheres, as its name suggests.
• The equatorial zone lies between 0 and 10 degrees latitude on either side of the equator.
• It runs from Sumatra to New Guinea in Asia, spanning the Amazon lowlands in South America, the Congo basin in Africa, and the East Indies.
• This region, in other words, covers the continents of South America, Africa, and Asia.
• Equatorial Rainforest Climate is also called the tropical rainforest climate or equatorial climate.

Extent of Equatorial Rainforest Climate

Equatorial Rainforest Climate- Temperature

• Temperatures are rather consistent throughout the year.
• The month of September has the greatest monthly temperature of 29°C.
• The coldest months are December and January, when the temperature drops to 26°C.
• The temperature fluctuates by 2°C during the course of the year.

Equatorial Rainforest Climate - Climatic Conditions

• With an average daily temperature of 28°C, this climate is extremely hot.
• The temperature rarely falls below 20°C and never rises over 35°C.
• The region's mornings are bright and sunny. In the afternoons, strong convectional rainfall occurs due to the high quantity of evaporation in the region.
• As a result, the region experiences a lot of rain. The yearly rainfall might be as high as 2500mm.
• The temperature is high and the humidity is high.
• The weather is almost constant throughout the year. There are no distinct seasons found here.

Equatorial Rainforest Climate- Soil

• The majority of the soil is deficient in nutrients.
• At the surface, a thin layer of fertile soil forms as the dead leaves decay.
• It is reddish in colour due to its high iron content.
• Nutrients are quickly flushed out of the soil due to excessive rains.

Soil of Equatorial Rainforest Climate

Equatorial Rainforest Climate - Vegetation

• Because of its warm and wet climate, the equatorial region supports a vast range of vegetation and is ideal for plant growth
• Various species of plants can thrive according to the climatic circumstances.
• The area is thought to be a genetic hotspot for a variety of animals.
• Within a few square kilometres, the region contains up to 3000 different tree species.
• The vegetation diversity includes everything from evergreen trees to lianas, as well as epiphytic and parasitic species.
• Plant Species have also adapted to the rainforest's conditions, such as trees and plants with shallow-reaching roots that take nutrients from the soil's thin fertile layer.

Equatorial Rainforest Climate - Wildlife

• The equatorial region is not only a home to lush and diversified plants but also a shelter to a wide range of wildlife as well.
• Many different animals, birds, and insects are supported by the diverse plant species.
• This region's fauna include the African elephant and the Jaguar.
• Mountain gorillas, lowland gorillas, chimps, and many bird species all call the Congo basin home.
• Other animals include the poison dart frog, margay, and collared anteater, sloths, toucans, spider monkeys and flying frogs.

Threats to Equatorial Rainforests

Deforestation

The Amazon Basin's tropical rainforests are under threat of destruction. Deforestation is occurring as a result of the following factors:

• Farming : Farming large tracts of land have been cleared for pastoral farming.
• As the global demand for meat has grown, more cow farms in the Amazon Basin have developed for beef production.
• As many farmers destroy land to grow cash crops like soybeans, agribusiness is also to blame for the destruction of tropical rainforest.
• Logging : It is the removal of tropical rainforests in order to gain access to valuable trees such as mahogany, which can then be sold for use in furniture.
• Other trees are felled for the production of paper.
• Mining: Natural resources such as iron ore, copper, tin, aluminium, manganese, and gold abound in the Amazon Basin.
• As a result, mines have been developed, resulting in the removal of tropical rainforest.
• Roads: The development of access roads for farmers, loggers, and miners results in the destruction of significant areas of tropical rainforest.
• Hydroelectric Power (HEP) - The construction of HEP stations in the Amazon Basin resulted in the flooding of enormous areas of forest to produce reservoirs and dams.
• The Balbina dam's inundation resulted in the loss of 920 square miles of tropical rainforest in Brazil.
• Population Growth: Land is cleared to develop dwellings and the development of infrastructure has resulted in the loss of tropical rainforest as a result of population growth.

Soil Erosion

• The earth is left exposed once the rainforest vegetation has been removed.
• The nutrients in the soil are washed away when it rains.
• As there are no plants or trees shedding leaves to replace the nutrients in the soil, the nutrient cycle comes to a halt.
• Since soil is no longer fertile, it can no longer support plant life. Plant and tree roots no longer hold the soil together, allowing it to dissolve readily.

Loss of Biodiversity

• Deforestation causes the extinction of many different plant and animal species.
• Deforestation diminishes the biodiversity, or range of species found in the tropical rainforest, because plants and animals are related through the food chain.

Climate Change

• During the process of photosynthesis, the Amazon Basin's trees and plants absorb carbon dioxide.
• Deforestation results in fewer trees and plants, which means less carbon dioxide is extracted from the atmosphere.
• Deforestation contributes to global warming and so the climate changes in this way.

Conclusion

Excessive heat and humidity have a harmful impact on people's health. The people of this region have become more susceptible as a result of climate change. While the hot and humid atmosphere of the equatorial rainforest climate encourages plant growth, it also encourages the growth of bacteria and pests. These, in turn, are to blame for the equatorial region's widespread illness prevalence. Malaria, lymphatic filariasis, and dengue fever are among the 58 diseases spread by vectors in this area.
