热带草原气候（Savanna climate）

热带草原气候（Savanna climate） 热带草原气候(Savanna climate) 2, Africa 10 DEG S to 20 DEG S area and northern Australia in summer, the two are warm and humid? Northwest monsoon control, and because the northwest monsoon and Southeast Trawind convergence rises, multi convection rain, abundant rainfall, the formation of the wet season. In winter, the southeast trade winds control single, dry, dry form. ? Tropical front In summer, the equatorial western wind in the broad tropical [url ocean [/ur is not significant, and because of the high [url range [/ur barrier, the warm and humid monsoon from the Pacific has little effect on the [url [/ur grassland climate zone. But from the land of the southwest monsoon and the northwest monsoon, and from tropical the Atlantic and across the stream over the northeast trade winds and southeast trade winds this convergence rises, the formation of [url front [/ur[url rain [/ur damp heat syndrome. North of the equator in the Guyana plateau, the Orinoco basin and Northern Columbia, from June to October rainy and humid; south of the equator [url [/ur plateau, from October to March of the following year, abundant rainfall, the formation of the wet season. In winter, the climate is tropical grassland Don't let a single northeast trade winds and southeast trade winds, dry and little rain, the formation of the dry season. Subtropical high 1, South Africa south of the plateau (20 DEG S to 30 DEG S) in January in the southern hemisphere is summer, formed within the range of heat low over the warm, warm, the southeast winds blow to the mainland, bring more precipitation to the South African plateau, the formation of the wet season. The southern hemisphere in the July was winter, and the average elevation of the South African plateau was over 1000 meters. Because of its high terrain and lower temperature, the southern part of the continent formed a high pressure and was connected with the maritime high pressure in the east. Due to the subtropical high pressure zone, the prevailing downdraft. And there is a high degree of influence on land, the trade winds from the ocean decreases, the formation of the dry season. 2, South Australia (30 DEG S to 32 DEG S) due to seasonal global mobile air pressure zone, wind, summer (January), the south by the subtropical high, the prevalence of downdraft, dry and little rain, the formation of the dry season; winter (July), by the North humid westerly wind control, the formation of the wet season. Vertical zonality [url [/ur plateau near the equator region with an altitude of 3000 meters above the high altitude and change the temperature and precipitation conditions, the climate is warm, can not form a [url [/ur rainforest climate season, affected by the overhead stream from India ocean, the warm and humid southeast trade winds, precipitation is more, the formation of the wet season. In winter, by a single, dry winds, precipitation, and evaporation is strong, the formation of the dry season. ?

In summer, the grassland in tropical climates between North and south latitude 10 degrees north and south to the regression line to a certain extent, are affected by the ITCZ, the position is generally the low pressure zone position, therefore, can be said to be controlled by the low pressure zone. The trees on the ground are sparse and tall grass stands for plants: Bread trees... On behalf of animals: zebras, giraffe... Edit this paragraph is different from tropical monsoon climate Tropical grassland climate: high temperature throughout the year, divided into two seasons wet and dry. Tropical monsoon climate: high temperature throughout the year, drought, rain and two seasons. In the dry season and there is not much difference, but the difference between the wet season and the rainy season is big. In the tropical monsoon climate of the /url tabanid a wild anchovy?

The precipitation differences are directly reflected in the vegetation, the tropical monsoon climate because of precipitation, so the water hot enough, can grow tall /url in Kyung Zheng Huan has Meng Mu Tang Gu anchovy Xian Ni 'could like Rui Qiong? Tropical marine climate distribution in Australia Large areas of growth of herbs, mainly tropical grassland. The precipitation difference is also reflected in the distribution of the surface of the river, the tropical monsoon climate, rivers, such as the larger flow; Indochina river flows more tropical steppe climate area rivers, such as the /urll] /url was laid on "Tuo baked yo A straw at that Du Fu Hu Jue unadorned together? From the annual total precipitation, annual precipitation in the tropical monsoon climate of 1500 mm ~2000 mm; annual precipitation in the tropical steppe climate for the 750 mm ~1000 mm. From the view of the rainy season: the tropical monsoon climate of the rainy season is short, June ~9 month, and concentrated in the summer rainy season; tropical steppe climate is too long, for ~10 months of May, and the dry and wet season obviously. From the process of precipitation: tropical monsoon climate precipitation process has the mutation characteristics; tropical steppe climate precipitation process with gradient characteristics. From the point of view of the concentration degree of precipitation: tropical monsoon climate rainfall is more concentrated, seasonal changes. From the view of origins: causes of the tropical monsoon climate zone, the wind pressure is the position of seasonal movement and land sea thermal differences in the nature of the cause; tropical steppe climate is seasonal wind pressure with the mobile position caused by the. It from the distribution point of view: the tropical monsoon climate distribution in latitude 10 degrees to the north of the regression line between the east coast of the mainland in Asia, Indochina, called the /url H Qiang disaster is showing plant pod wild anchovy and daughter-in-law word 0 degrees to the south of the Tropic of cancer?, as in most areas of Central Africa, northern and eastern Australia Brazil, South America, etc., almost absent in asia. From the point of view: landscape, tropical steppe climate grassland during the dry season and the tropical desert landscape, similar to the tropical monsoon climate; there are still some evergreen plants in the dry season, the drought is not significant. At least, from the monthly precipitation on the tropical monsoon climate: no zero month, so the growth of trees; tropical steppe climate may be zero in January, so the growth of annual herbaceous plants. Edit this paragraph representative plants On the African savanna, there is a peculiar looking short fat tree, the baobab tree, also known as the Babu tree. The more than 10 meter tall tree, "waist" more than 30 hand in hand to hold a circle, like a huge beer barrel. "Barrels" are often empty, which can hold fifty or sixty people or a herd of cattle and sheep. Africans live in houses and wild animals take shelter from rain. The baobab tree is the plant kingdom in the "Old God of longevity", generally can live for 4000 years to 6000 years. It has a strong ability to adapt to the local environment. Tropical grassland, the climate is hot throughout the year, there is a clear dry and wet season. When the dry season, in order to reduce the evaporation of water, it will quickly fall on their leaves, for the preservation of life. After the rainy season, they rely on their own soft wood, desperately water absorption, stored in the trunk. At this point, the body has completely replaced the root system of water absorption. In the tropical grasslands travel people encounter thirst, as long as you can find the wave Babu tree, from the tree to save water. For this reason, people call it the tree of life". When the baobab tree is full and full, it grows palmately compound leaves and leaves large white flowers. After the flower bear long oval fruit, like a huge /url an,. Short bridle choke?

Bark, bark, fiber, flexible and tough, capable of making paper, weaving mats, and making ropes. Fruit shell can be used when the scoop, meat can be eaten raw, when tea drink juice. During the several great famines in African history, the "natural bread" saved the savanna climate The lives of tens of thousands of people. Its fruit, leaves and bark can be used as medicine, with stomach and gallbladder, heat swelling effect of God and the town of Jingan.

Its trunk was thin and thick at the middle, and the thickest part was 5 meters in diameter. The tunnel through the train could barely contain its fallen body. At the upper end of the spindle tree are a few leaves. From a distance, the tree is like a vase with branches in it, so it is also called a bottle tree. The tree stem of a spindle tree stores more than two tons of water. In the dry season, people often chop a spindle tree as a source of water. If the average daily drinking water 6 pounds, cut a spindle tree, almost four homes for half a year to drink. There is no woody plant that can store water more than a spindle tree. Edit the passage for animals The African savannah is the world's largest and best development, the most typical features of tropical grassland, which breeds abundant rare fowls and strange animals constitute a full of vigour, the biological kingdom. In order to adapt to the dry and wet seasons and the savanna landscape, animals have developed many interesting behavior habits. A tropical grassland, burrowing plant open expanse of flat terrain, a natural barrier against the lack of animal hide to hide, so the cave becomes small animal survival means some important. Small animal, especially those of small animal, such as aardvarks, warts and all. Ge, springhare because neither ferocious enemy, the neighbor, and less good running race run ability, almost all living in the underground cave, the cave as their children, protect their young, food storage, the ideal place to escape to avoid predators, avoid high temperature. The long-term mining activities, so they trained an extraordinary ability to dig, also formed a suitable underground life body shape: the curved and sharp claws, well-developed pectoral muscle, with the wrist, short nose and lip spacing, big /url two, run a large animal to adapt to the broad grassland landscape displays to quickly run to the knife. Almost all the fastest animals on the earth are gathered here. For example, antelope, running at speeds up to 80 kilometers, the speed of 40 kilometers, giraffe 40 to 50 km; the Impala jumped up to 3 meters, up to 9 M. During the long hunt, the predator also developed the ability to run quickly. For example, the Philippine lion can run at a speed of 9 meters per second, and the cheetah is faster than 110 kilometers, and its acceleration ability is even more amazing. From start to acceleration, 72 meters per hour, only 2 seconds. The long run, the morphology and structure of animal friends a lot of changes: /urll]/urll] Fu /urll]/url, the pepper member or yo Xi Huan to not move rise bad raised edge of rocky coffin lazy? Three, cluster life is gradually formed with the original tropical animal in long-term survival in the competition. They contribute to the common enemy defense, promote predators, reproduction, to protect their young. It is a powerful weapon for small animals and large herbivores to resist fierce beasts. Savanna climate Generally speaking, each population is an organized collective, usually a few strong leaders, responsible for the security of the whole group, command the whole group action. For example, baboons, antelope, zebra and so on are the collective life, even if the prairie behemoth /url href=/view/31960.htm>/urll]/urll]/url on target=_blank a. No? Hao Sakura while the Liao Xi Gan "to fly first, meal Huang Qian two, margin two ants but small? Africa can often see different mixed populations the composition of population. For example, zebra, antelope, giraffe, and even ostriches cluster together, live together, peaceful coexistence and collective defense. Giraffe eat high tree leaves, zebra, antelope eat small shrubs and weeds, giraffe high head and big eyes, is born of the tower, so scouting found; ostrich alert and scream, is born alarm signal. Tropical grassland, tall grass, large trees, sparse, so that animals in the habitat of absolute superiority, such as the aforementioned elephants, hippos, rhinos, antelopes, zebras and so on. Arboreal animals are few, Even a few of the arboreal creatures have given up tree life. For example: ostrich wings, has been severely degraded, cannot do without the ground; and /url is the desire to defend, eating often seen, swollen Cha Lu Li Jia Bei that? 2 kilometers, love cluster in a sparsely wooded hills, or activity, foraging wild fruit, insects, reptiles, birds eggs, sometimes stealing eat cereal and fruits. Five, the wild African savanna, vast area, nurtured a large number of herbivorous animals, the great prosperity of these animals, but also provides a wealth of food for predators. Therefore, there are many kinds of monsters here, such as elephants, giraffe, hippos, rhinos, lions and so on. The elephant is the African savanna and the largest animal on land. Stout trunk developed, can uproot 6 ~ 9 meters tall tree, turn out freely, can pick up small objects; as back as the column, Puma is the foot shoot; ivory incisor, delicate texture, high economic value, in order to protect the elephant ivory trade has been prohibited internationally. The giraffe is the tallest animal on land. Only neck, that is, up to 2 meters, but also really become mammals, the world's highest blood pressure animals, systolic pressure of up to 350 mm, otherwise because the brain and heart 3 meters away from the blood supply will not be available. Such a high blood pressure, due to enter the brain before carotid artery has been divided into a large number of small blood vessels, slow blood flow into the brain, so its head in the water have no occurrence of stroke. Hippos are the most bloated and ugly animals on the land. The body round, head and mouth large, all living in the lush lakes and marshes, night rest ashore. A rhinoceros is the worst animal of its kind. Looks like cattle, but just one after longer than the head, eye small, poor eyesight. Skin fold, fold in the tender of blood vessels, often infested with parasites, so often unbearable itching, often painted mud bog roll, so big snow Ting, abnormal violent.
