De-stitching the Arctic belt. Arctic and Antarctic climatic belts

antarctic belt- most recent geographic zone Lands, including Antarctica and adjacent islands, Pacific, Indian and Atlantic Ocean with a cordon in the boundaries of 48-60 ° north latitude.

Typical duzhe suvoriy Antarctic climate, with a low temperature of chill ric, as in the center of Antarctica there is a pole to the cold of the Earth. charge Average temperature become like - 60 to -70 ° C, Characteristic triva polar nіch. During the middle of the day, the temperature changes from - 30 to - 50 ° C, whish - 20 ° C do not get used to. The level of radioactivity is very large, up to 30 kcal / cm² per month, and only 10% of the heat is needed for heating the lower surface, because a part of the energy is brought into space, which results in a negative radioactive balance. Fall away from the viglyadі sіgu, іх number of changes from the Uzbek coast to the center of the mainland, apparently, from 500-700 to 30-50 mm ... On the Uzbek coast, there is strong runoff up to 12 m / s, part of the storm and fog, and in the central regions of the mainland it is quiet and the weather is clear.

Sit down on the oceans, cover the krygoyu. The area of ​​ice cover varies from season to season, up to 500-2000 km wide. The top of the bottom is divided by great valleys. A little bit of time for Uzbeks, the vuzka smuga of the rising ice, the surface of the water is cold. characteristic feature Antarctic waters є icebergs.

On land, the landscape of the Antarctic sheaths zone is overwhelmed, the main part of the mainland is covered with ice cover, it is not possible to develop Antarctic oases - bare areas of the land - in the coastal regions. Likewise, do not cover with ice the dilyanki of the girskih massifs and okremikh skel - nunataks. Vishche 3000 m is an area of ​​frozen ground. Near the coastal oases, lakes grow in the main dry and salty lakes, as well as lagoons in the soaked shelf ice lakes, the river is not.

Flora and fauna

roslinny i tvarinny svit Antarctica is free through її trivial іsolіatsії. We will explain the visibility of land use and freshwater ribs. A bit of the mainland skeleton is heated to a temperature of 0 ° C, and lichens, moss, fungi, algae, bacteria grow on them in small pieces. Spineless small sizes are seen: rotovers, tardigrades and deyaki vid and non-crusty comas. I want Antarctic water and cold, a little stench of riba and other crayfish (krill). Seals live near the Antarctic zone, seals and whales, sea birds nest on the Uzbek coast, and the penguins, skuas, albatrosses themselves. On the islands, the growth of the tundra grows, there is a lot of ptahiv.

State-owned activities, only science, have been fenced in to the international lands in Antarctica. A wide number of doslіdzhen and caution is carried out by rіznih lands, Especially behind a wintry climate in natural minds without a human factor.

Arctic belt - climatic zone, Yaka Zaymaє poles of the planet. For a new characteristic, borderline low temperatures and especially natural phenomena: Pivnіchnі syayva, polar nights and days, coverage of hummocks and pack ice.

Most of the area is occupied by the Arctic belt in Antarctica, expanding to the entire continent. On the winter planet, the wine includes the private parts of the Eurasian and Indian American continents, Baffin Earth, Greenland, Taimir, archipelago Nova Earth, Ostrіv Spitsbergen and іnshі islands North The icy ocean... Most of the private aquatic areas of the Atlantic and Pacific oceans are often set up.

climat

Tsі mісця is characterized by a persistent climate. Low temperature - The main specialty, Шо відрізня Arctic Belt. The temperature in cold and cold weather is negative here; Meteorological indicators of the central region were filled with cold wind masses. Sleepy lanes, which fall on the planet along the road, do not warm up the permafrost.

Especially suvorі winter in Antarctica. At the radio station "Vostok", a record low temperature of -89 ° C was registered here.

Falling off at the poles of the planet vipadaє is even smaller - less than 250 mm per rik. The Arctic belt is occupied by the Arctic and Antarctic barrens. The stench is a long-lasting shell of ice lions.

Day and night

Most of the bags sounded before, on a light day, half to a third dobi. Nich and a day according to pivrok is an extravagant phenomenon, typical for territories, to enter the Arctic belt. The temperature is in cold and lime, the amplitude of which becomes close to 50 ° C, even less than zero. Indicators range from -10 to -60 ° С, drop down to -70 an hour and move lower. Nakhil wasps of the planet amumovlyu tse unique phenomenon, characteristic of the poles. They call this special day and not a polar one.

Arctic zone of delusions of yaskravoy rozkoshi. What is the beauty of Suvor і streman, and what is more? The presenters of the Arctic and Antarctic write about the time, not economical to turn in the best step. The majestic kryzhani wastelands, the shining bulk of icebergs, how the hummocks drift and the steps of ice drift - all the wickedness is at once fear and drowning.

Lodi mold the relief of Antarctica, the very on the continent... The stench will cover the greater part of the Pivnichniy Pole. The Arctic, which is challenged by Rizdvyanim in the most prickly virases, is occupied by tedious ice-dwellers. A large part of the aquatoria of the Pivnichny Ice Ocean is stored in ice. Seasonal tannins are typical only for the middle latitudes of the belt, which cross the Eurasian continent. Lito in qix latitudes is short; At the whole hour of the coast mainland ice fix the pidtavati, consuming up to 10% of the debt. With the winter's nastannyam, everything will turn to square one.

Flora and fauna

The nature of the arctic belt is monumental, as is the size of the sack. At the top of the grub lance є an unfailing hijak - biliy vedmid. Vin wanders into the human settlement, it is not easy to start, for example, the inhabitants of Spitzbergen and the New Earth. The spirited king of the Arctic, is not a majestic natural enemy, except for the people. This year's beast is known to be guarded, ecologists follow the number of populations.

There are majestic whales, walruses, and pickles near the cich regions. Coastal zones - the favorite life of seals.

Є In the polar zone, bags are more modest. For example, lemings are motor grizzlies, as they do not fear low temperatures. There are majestic herds of reindeer in the districts. The most unsafe huts for the bold bearer come into the world and polar foxes - polar foxes.

The Arctic belt cannot boast of the great versatility of the flora. Ale here is to grow navіt kvіti! Polar poppy and lomik in latitudes belts. And once in a girskiy mіstsevostі you can create a new edelweissy.

It is of the greatest importance to lick lichens and moss, the stench will obscure areas that are not occupied by ice dwellers.

Nasichene sour food is another feature that characterizes the Arctic belt. The temperature is inflated and charged in the first place near the cordon, but it is positive, and it is more beautiful because of the best water, by reducing factors in the development of bags of the water kingdom. In the Arctic waters, there is a great number of valuable ribi.

Climatic belts are called a singing part earthly surface with a singing climate, a circulating atmosphere and an intensive heating by Sonce.

There are 7 main types of climatic belts on Earth. In a wide view, it stinks on post-and-transition. We are gradually called climatic belts, In which there is only one povitryana masa... And in the transitional - development and change of mass. Before the post-transitional ones are: equatorial, tropical, peaceful and arctic, and before the transition ones - subquatorial, subtropical and sub-arctic.

Natural zones and arctic and antarctic belts

Arctic climatic belt

Siberian Uzbek Russia, roasted on the Uzbek coast of the Pivnichny Ice Ocean, and adjoined to a new island and lay down to the Arctic belt. The winyat is the territory of the island of Novaya Zemlya, the islands of Vaygach, the islands of Kolguyev and the other islands that have grown on the territory of the Barents Sea.

Siberian Uzbek tsiliy rik to be in the minds of the arctic climate, sleepy radioactivity to come to the Siberian land only in a small amount. And in return, since Siberia is in the possession of the polar night, the sleepy radioactivity does not come to the ground in the distance. Once the water is heated, the deyaky povitryany prozharki. The temperature itself is average on the mainland, but not on Uzbek.

Atlantic flowing into previous territories Siberia, bring it to the warmth of the twilight.

From the hour of the polar day to the sleepyhead insolation. There is a lot of sleepy energy going on for those who are hot and cold. And all the same, the temperature rises - in limes it is close to 0 degrees, and on Uzbek it is +5 degrees. The private part of the Siberian territories will warm up to +10 degrees.

For rіk here vipadaє is close to 200-300 mm snig.

Antarctic climatic belt

The whole Antarctic natural belt... Winning the territory of Antarctica, adjacent islands and part of the Pacific, Indian, Atlantic oceans.

Here panun cold suvoriy klimat. In winter, the temperature becomes from -60 to -70 degrees, and from -30 to -50. Set the maximum mark on the thermometer to -20 degrees.

To reach a high level of radioactivity, about 30 kcal / cm² per month, if only a small part of it is needed for heating the surface of the Earth - 10%. Everything is going into space. The very fact on the cycle of the territory is the decrease in the radio balance.

The number of fallen leaves in the snow changes in the fallowness of the territory. Chim is closer to the center of the mainland, less fallen. On the Uzbek coast, there is a strong wind, which can reach up to 12 m / s. By enduring manifestations, the oceans are close, storms, fogs, even though at the same hour in the center of the continent it is sleepy and clear.

Part of the oceanic surface is covered with ice. The scale of the curves lies as far as rock, and at the peak the reach is 500-2000 km. wide. Icebergs are often seen here.

On land, there is an arctic wilderness, including an ice cover. Antarctic oases are growing more often in coastal areas. Deyaki girski masivi are also relieved from the kryzhany kirka, the stench is called nunataks.

Greenland and Antarctica are ordered by the Antarctic and Arctic belts.
