Climatic characteristics of tropical grassland

The climate characteristics of the savanna are as follows:

1. Temperature: It is high all year round, with an average annual temperature of about 25℃, and there are few cold weather even in winter.

2. Precipitation: The annual rainfall in the tropical grassland climate is generally between 7 and 1 mm, which is obviously concentrated in the wet season, that is, the rainy season (controlled by the equatorial low pressure zone), while there is almost no rain in the dry season (controlled by the trade wind zone).

3. Vegetation: The plants in the tropical grassland are xerophytic, and most of them are Gramineae, and the height of the grass is generally between 1 and 3 meters. Representative tree species are Spindle Tree, Acacia Tree, Bobdog Tree, etc.

4. Animals: Typical animals include giraffe, hippo, rhinoceros, African lion, wildebeest, zebra, jackal, cheetah and so on.

the tropical grassland climate is mainly distributed in the mainland and the western coastal areas between 1 north and south latitude and the tropic of cancer, with central Africa, most of South America and Brazil, and northern and eastern Australia as typical examples. People in this climate type will store food and water in the dry season, and increase outdoor activities and production in the wet season.

Impact of the savanna climate:

The savanna is vast and flat, lacking natural barriers for animals to hide from the enemy, so burrowing has become an important means of survival for some small and medium-sized animals. Small and medium-sized animals, especially those small and weak animals, such as aardvark, warthog, jumping rabbit and all kinds of rodents, have neither fierce ability to defend the enemy nor the ability to run away, and almost all of them burrow underground.

caves have become an ideal place for them to have children, protect their young, store food, escape from enemies and avoid high temperature. Long-term controlled excavation activities have enabled them to practice an extraordinary ability to dig, and also formed a body shape suitable for underground life: curved and sharp claws, developed pectoral muscles, combined carpal bones, short lip-nose spacing and large front teeth.
