The influence of the savannah climate, the characteristics of the savannah climate

Group life is gradually formed by savannah animals in the long-term competition for survival. Living in groups is conducive to fighting enemies together, defending against enemies, promoting reproduction, and protecting the young. It is advantageous for weak animals and large herbivores to resist fierce beasts**.

Generally speaking, each type of group is an organized collective, usually led by several strong people, responsible for the security of the whole group, and directing the actions of the whole group. For example, baboons, antelopes, zebras, etc. live in groups, and even steppe giants such as elephants, giraffes, hippos, rhinoceros, and bison also like to live in groups.

10. Even hundreds of heads live together, foraging for food, playing, and fighting enemies together. Mixed populations of different populations are also often found in the African savannah. For example, zebras, antelopes, giraffes, and even ostriches gather in groups to live together, coexist peacefully, and defend collectively.

Giraffes eat tall young leaves, zebras and antelopes eat small shrubs and wild grasses, giraffes have high heads and big eyes, they are natural watchtowers, and they are good at reconnaissance and discovery; The ostriche's alertness and screaming are natural alarm signals.

The savannah is tall and grassy, and the trees are sparse, so the terrestrial dwellers are overwhelmingly dominant among the animals, such as the aforementioned elephants, hippos, rhinoceros, antelopes, zebras, etc. There are very few arboreal animals, and even the few animals that should have lived in the arboreal have abandoned their tree life. For example:

Ostriches, whose wings are severely degraded, can no longer leave the ground; Another example is the baboon, the body is petite but the four glues are stout, suitable for running on the ground, the speed is more than 32 kilometers per hour, like to gather on the sparsely wooded stone mountains, frequent activities in the morning and dusk, eating wild fruits, insects, reptiles, bird eggs, and sometimes stealing grains, melons and fruits. The vast African savannah, which is home to a large number of herbivores, is a great abundance of food for carnivores. Therefore, there are many species of giant animals here, mainly elephants, giraffes, hippos, rhinoceros, lions, etc.

Elephant. It is the savannah of Africa and the largest animal on land. The trunk is thick and well-developed, can uproot a large tree 6 9 meters high, and can stretch freely, can pick up small objects on the ground; The elephant's legs are like pillars, which can trample lions and leopards to death; Ivory is its incisor tooth, with a delicate texture and high economic value, and in order to protect elephants, the trade in ivory has been strictly banned internationally.

Giraffe. It is the tallest animal on land. The neck alone is 2 meters long, which also makes it the animal with the highest blood pressure in the animal world, with a systolic blood pressure of up to 350 mm, otherwise there would be no blood supply due to the distance between the brain and the heart 3 meters.

With such a high blood pressure, the carotid artery has divided into a large number of small blood vessels before entering the brain, and the blood flow slowly enters the brain, so there will be no cerebral hemorrhage when the head is lowered to drink water.

Hippopotamus. It is the most bloated and ugly animal on land. With a round body and a huge head and mouth, he lives in rivers, lakes and swamps with abundant water and grass all day long, and goes ashore to rest at night.

Rhinoceros. It is the most bad-tempered animal. It looks like a cow, but the two horns are one in front and one behind the top of the head, and the eyes are small and the eyesight is poor. **Multiple, pleated flesh and multi-vescular, often breed a large number of parasites, itchy and unbearable, so often go to the mud pond to roll and smear the mud, and often get angry because of this, crazy and abnormal.

Science Encyclopedia Tropical savannah climate.

Tropical savannah climate characteristics: high temperature all year round, divided into dry and wet seasons, less rain in the dry season, and more rain in the wet season.

The savannah climate area has high temperatures throughout the year, divided into two distinct dry and wet seasons, with an annual rainfall of 700 to 1000 mm, mostly concentrated in the wet season. Temperatures in the dry season are higher than in tropical rainforest areas, with average daily temperatures ranging from 24 to 30.

The continental depression moves northward in May and October every year, when the southwest monsoon (also known as the Guinean monsoon) blowing from the Gulf of Guinea prevails in the savannah of the Northern Hemisphere, bringing abundant precipitation and forming a wet season. From November to April, the continental depression moves southward, and the northern hemisphere savannah prevails with trade winds (Hamadan winds) from the northward recapitant high pressure zone, which is very dry and forms a dry season. The dry and wet seasons in the hot grass belt grasslands of the Southern Hemisphere are exactly the opposite of those in the Northern Hemisphere.

Savannah climate distribution area.

It is roughly distributed between 10° north and south latitude and the Tropic of Capricorn, with central Africa, most of South America and Brazil, and the northern and eastern parts of the Australian continent as typical examples. The distribution area of this type is in the alternate control area of the equatorial low pressure belt and the trade wind belt.

The African savannah is the world's largest, best-developed and most typical tropical savanna, in which rare birds and animals are extremely rich in life and breeding, constituting a vibrant biological kingdom. In order to adapt to the ecological landscape of alternating wet and dry seasons and sparse grasslands, animals have developed many interesting behaviors.

The cause is the result of alternating control of the wind belt and the air pressure belt.

The savannah climate, also known as tropical dry and wet season climate, Savannah climate, savannah climate, and tropical sparse forest steppe climate, is roughly distributed between 10° north and south latitude and the Tropic of Capricorn, and is typical of central Africa, most of South America and Brazil, and the northern and eastern parts of the Australian continent. The distribution area of this type is in the alternate control area of the equatorial low pressure belt and the trade wind belt.

The temperature is high throughout the year, the average annual temperature is about 25 °C, and the temperature is high throughout the year, and it is divided into dry season and wet season. When the equatorial low pressure zone is controlled, the equatorial air mass prevails and precipitation is concentrated. During the period when the trade wind belt is controlled, it is controlled by tropical continental air masses, and there is drought and little rainfall. Annual precipitation is generally 700-1000 mm, with a significantly longer dry season.

The natural landscape is a savanna.

The causes of the savannah climate can be summarized as:

1. Monsoon type.

In the middle of summer, at low latitudes (especially on the mainland), an equatorial westerly circulation is often inserted into the trade wind belt of the northern and southern hemispheres. Its formation, on the one hand, is due to the seasonal movement of the planetary wind belt; On the other hand, due to the heating effect of the continent, it also contributed to the strengthening of the equatorial trough when it moved.

2. Tropical front.

In summer, in the vast eastern tropical Pacific Ocean, equatorial westerly winds are not significant, and because they are blocked by the tall Andes Mountains, the warm and humid monsoon winds from the Pacific Ocean have little effect on the savannah climate of South America. However, the southwest monsoon and the northwest monsoon from the land converge with the northeast and southeast trade winds from the tropical Atlantic Ocean and pass over the warm current to form a tropical front, with more convective rain and a humid and hot climate.

The climatic characteristics of the savannah are as follows:

1. Introduction

Savannah climate is a grassland climate located near the equator, and its main characteristics include high annual average temperature, low precipitation, large temperature difference between day and night, strong wind, grassland vegetation, and abundant animal and plant resources.

2. Climatic characteristics.

The average annual temperature in savannah climate areas is high, generally above 20. Temperatures can reach over 30 in summer and high temperatures in winter. This is due to the proximity of the savannah climate region to the equator, which is subject to strong solar radiation and higher temperatures.

3. Precipitation

Rainfall is low in savannah climates, generally between 500 and 1000 mm, and is concentrated in summer. This is due to the fact that savannah climate areas are affected by the monsoon, which brings more precipitation in the summer monsoon and less in other seasons.

4. Temperature difference between day and night

The temperature difference between day and night in the savannah climate area is large, hot during the day and cool at night, and the difference can reach more than 10. This is due to the combined effect of factors such as climatic conditions and topography in savannah climate areas.

5. Strong wind

In savannah climates, there are strong winds and seasonal winds throughout the year, such as the summer monsoon. This is due to the fact that savannah climate areas are affected by the monsoon, which brings stronger winds.

6.Diversity of species

The savannah climate area is rich in flora and fauna, with a large number of herbivores and predators, such as lions, zebras, antelopes, etc. This is due to the fact that the climatic conditions and vegetation conditions in the savannah climate area provide a suitable ecological environment, so that the animal and plant resources have been fully developed.

7.The vegetation is grassland

The vegetation in the savannah climate area is dominated by grassland, and the grassland vegetation adapts to the environment of drought and high temperature.

In short, savannah climate is a special type of climate, which is characterized by high annual average temperature, low precipitation, large temperature difference between day and night, strong wind, grassland vegetation, and abundant animal and plant resources. This type of climate has a certain impact on human production and life, which requires us to study and improve carefully.

The climate of the savannah is influenced by the alternation of the equatorial low pressure zone and the trade wind belt.

Reason: The savannah climate, also known as tropical dry and wet season climate, Savannah climate, tropical savannah climate, and tropical sparse forest steppe climate, is roughly distributed between 10 degrees north and south latitude and the Tropic of Cancer, with central Africa, most of South America and Brazil, and the northern and eastern parts of the Australian continent as typical. The distribution area of this type is in the alternate control area of the equatorial low pressure belt and the trade wind belt.

Temperatures are high throughout the year, with an average annual temperature of about 25 degrees Celsius. During the control period of the equatorial low pressure zone, the equatorial air mass prevailed, and the precipitation of wide dust was concentrated. During the period when the trade wind belt is controlled, it is controlled by tropical continental air masses, and there is drought and little rainfall. Annual precipitation is generally between 700 and 1000 mm, with a significantly longer dry season.
