On Earth, there are a variety of climaticbelts, each of which is accompanied not only by a certain temperature regime, but also by completely different representatives of flora and fauna, original relief and many other features. Their study allows us to better understand the diverse nature of the planet. For example, subequatorial belt. What characterizes him?
Key Features
On the planet there are two subequatorialbelts, one in each hemisphere. They cover an area between 20 and 30 degrees. In the World Ocean, the subequatorial belt coincides with the border of the Passat currents. Its climate is different monsoons and the change of air masses according to the season. In the summer, a humid wind blows the area, in the winter - dry and tropical. The average temperature of the cold season ranges from 15 to 32 degrees, accompanied by frosts and snowfall only in the highlands. The ocean water in this belt is always at a temperature of plus 25. In combination with increased salinity, this leads to a rather low biodiversity in the basin.
Territorial differences
Характеристика субэкваториального пояса отмечает its main features, but there are differences due to each particular place. For example, in areas located at the equator, the maximum amount of rainfall that occurs over nine months and creates up to two thousand millimeters of precipitation. On the mountain ranges, this figure increases six times. However, in some regions periods of drought are possible. For example, in Africa, the fluctuation of the water level is so strong that lakes and rivers full of water in summer simply disappear in winter.
Vegetable world
Subequatorial climate zone is differentred or yellow soils that quickly decompose organic matter. This leads to the appearance of particular plants. They are well adapted to local humidity and rainfall - they grow in many tiers and are distinguished by thick, thick leaves and a strong root system. Biodiversity is impressive: here you can find many types of trees with edible fruits or valuable bark, there are coffee trees, palm trees. The subequatorial belt includes savanna zones. They differ in separately growing trees with extensive thickets of bushes and high grass. The savannah is more fertile red-brown soil. Vegetation is represented by such species as acacia, palm trees, baobabs, mimosa. In the driest areas they are replaced by aloe. The abundance of forbs is also characteristic of savanna regions.
Animal world
The diversity of fauna directly depends onvegetation, which is different subequatorial belt. In the areas of tropical forests in the loose soil inhabited by various invertebrates and microorganisms. In the lower tier you can meet forest pigs, okapi, small ungulates and even elephants. Dwarf hippos and gorillas live in areas with water bodies. Various primates, rodents, birds and insects inhabit the trees, of which ants and termites are most common. The largest predator is the leopard. In the conditions of savanna there live various types of ungulates, including buffaloes, antelopes, and zebras, and rhinos. There you can also meet elephants, hippos, giraffes. Predators are also diverse: cheetahs, lions, hyenas, jackals live in the savannah. The world of birds is represented by ostriches, secretaries birds, marabou storks. Of the birds, ostriches can also be noted, which are sometimes found even in the Sahara. In the most desert regions there are many lizards and small snakes, small antelopes live there.
