The subequatorial belt is usually called transitional due to the circulation of various air masses. In the summer of the year equatorial, and in the winter tropical. Due to such features, summer begins with a protracted season of heavy rainfalls, and winter is characterized by drought and moderately warm climate. The remoteness or proximity to the equator significantly affects the level of precipitation of annual precipitation. In summer, the rainy season can last about ten months, and as it moves away from the equator, it will decline to three months in the summer season. There are many reservoirs in the zones of the subequatorial belt: rivers and lakes that dry out with the advent of winter.
Natural zones
Subequatorial climatic belt includes several natural zones:
Savanns and editorials are observed in the territory of South America, Africa, Asia and Oceania. They belong to a mixed ecosystem with extensive meadow lands suitable for pastures. The trees are located everywhere and occupy large areas, but they can alternate with open areas. Most often, savannahs are located in the transition zones between the forest belt and the desert. This ecosystem is about 20% of the entire land of the Earth.
It is customary to attribute South America, Africa and Asia to the field of highaltitude span. This natural zone, which is located in mountainous areas, can be described: a sharp decrease in temperature within 5-6 degrees. The amount of oxygen is significantly reduced in the mountains, atmospheric pressure decreases and solar radiation increases significantly.
South and North America, Asia and Africa are attributed to the zone with alternating forests. The prevailing seasons in this part: dry and storm, so vegetation has no great variety. The main breeds of trees are a broadleaved leafy vegetation. They well perceive sharp changes in weather conditions: from heavy rains to the arid season.
Wet equatorial forests are found in Oceania and the Philippines. This type of forest is slightly distributed, and evergreen breeds of trees are included in it.
Soil features
In the subequatorial belt, the prevailing soil is red with a variable moist tropical forests and highgrass savannah. The Earth has a reddish tint, a granular structure. It contains up to approximately 4% humus, as well as a high iron content.
In Asia, there may be: black chernozem soils, yellowearth, redearth.

Flora and fauna
In the subequatorial zone, savannahs with large pasture lands are most often found, but the vegetation is an order of magnitude poorer than in tropical equatorial forests. Unlike vegetation, the most diverse world. In this belt you can meet:
Among the birds you can meet here:
The most common insects are: ants, butterflies and termites. A large amount of amphibians live in this belt.
