What are the main characteristics of the polar ice sheet climate?

The polar ice sheet climate is mainly found in the interior of the Antarctic continent and Greenland. It is very cold throughout the year, and the average temperature is below freezing, which is the lowest temperature in the world. The average annual temperature in the Antarctic continent is -29 to 35 degrees, and in the Arctic it is below -22 to 12 degrees, and there are many snowstorms throughout the year.

The polar tundra climate is mainly found along the Arctic Ocean coast of the Eurasian and North American continents. It is often affected by glacial ocean air masses and polar continental air masses, and is cold all year round. The average temperature of the hottest month is 1-5 degrees, with less precipitation, weak evaporation and higher cloud cover.

The natural vegetation is mainly tundra (mosses, lichens). In the highest latitude area, the solar altitude angle is very low all year round, sometimes almost 0, therefore, here is the birthplace of the ice ocean air mass and the Antarctic air mass, the whole winter is in the polar night state, although the summer half of the year is the polar day, but the sunlight is oblique, the heat obtained is weak, so the climate is severe throughout the year, and the temperature of each month is below 0. Thus forming an ice sheet climate.

What are the main characteristics of the polar ice sheet climate: The polar ice field climate, one of the climate types, is located near the poles, mainly distributed in the Antarctic continent and the interior of Greenland, and is also distributed on several islands in the Arctic Ocean. This is the source of the Ice Ocean air mass.

There are periods of the year when it is a polar night and does not receive solar radiation. In the climatic areas, the ground is mostly covered with huge snow and ice, and there are many cold storms, which makes it difficult for plants to grow. First, it is very cold all year round.

The average temperature of each month is below 0, which is the lowest annual average temperature in the world, and the average annual temperature of the Antarctic continent is between 29 and 35. During the polar daylight period, the average temperature of the hottest month is -4 -25 5, and the average temperature of the coldest month is around 160. The average annual temperature in the Arctic is below 122.

Second, the amount of snow is small, but it accumulates over a long period of time, forming thick ice sheets.

The annual precipitation is less than 250 mm, all of which is snowfall, and even during the polar day, the snow does not melt because the sunlight is too weak, and there is only a loss of evaporation. Strong winds, cold sleet, poor visibility. Due to the cold climate, there is no melting period of ice and snow, and there is almost no vegetation, only some mosses, lichens and other lower plants grow in a few ice-free fields.

This is the birthplace of the ice ocean air mass and the Antarctic air mass, the whole winter is in the state of eternal night, although the summer half of the year is eternal day, but the sunlight is oblique, the heat obtained is weak, so the climate is severe cold throughout the year, and the temperature of each month is below 0; The average annual temperature of the Antarctic continent is -25, which is the coldest continent in the world, and the absolute minimum temperature measured by the Norwegians in 1967 can be called the "cold pole" of the world. It is found in and around the polar regions, including Greenland, several islands in the Arctic Ocean, and the glacial plateaus of the Antarctic continent.

The climatic characteristics of the ice sheet are as follows:

The north of the Arctic Circle is the boreal zone, and the south of the Antarctic Circle is the boreal zone. The polar temperatures are low and cold all year round, especially in winter, when snow storms occur, and it is extremely cold.

The length of day and night varies the most in the ice sheet climate zone, with polar day and polar night phenomena, and no obvious seasonal variation. Polar climate zones cover 10% of the Earth's total area. Precipitation is scarce, mainly snowfall, solar radiation is weak, ground radiation is strong, and there have been extreme minimum temperatures on Earth.

The soil is glacial marsh and permafrost, the vegetation is scarce, the representative animals are polar bears and penguins, and there is an aurora landscape.

Animals are represented

Penguins are all found in the Southern Hemisphere; There are about 8 species in the Antarctic and Subantarctic regions, of which 2 species breed on the coast of the Antarctic continent and the rest on the islands between the coast of the Antarctic continent and the subantarctic. Penguins are often found in very large groups, accounting for 85% of the seabird population in Antarctica. Penguins are flightless birds.

Able to swim in the water. Its main food is small fish and krill. Penguins usually live a long life, such as king penguins can reach 20-30 years old. Because of its beautiful posture and living like a gentleman, it is also a major landscape on the continent of Antarctica, and is known as the "Antarctic Gentleman" and "Antarctic Master".

The polar climate is characterized by the following:

Polar climate, also known as boreal climate, includes two types: icefield climate and tundra climate.

The ice sheet climate is distributed on the Antarctic continent and some islands in the Arctic Ocean, and the ground is covered with a thick layer of ice and snow.

The tundra climate is distributed in the northern edge of the Eurasian continent and the North American continent, with no summer and no summer, and plants such as mosses and lichens grow on the ground.

Overview of the Arctic Climate:

In the most classical climate classification, boreal climate refers to the climate within the polar circle. In the Köppen climate classification, it refers to a polar climate (cold all year round, with temperatures below 10 in the hottest month. includes tundra and icefield climates.

In the Alisov climate classification, it is equivalent to the combined name of the sub-North (South) Pole Zone and the North (South) Pole Zone.

In the Scharle climate classification, it includes the subpolar continental climate (long winters, short summers, and the temperature of the hottest month is above 10, also known as the taiga climate or snow forest climate), the polar cold climate (the temperature of the hottest month is between 0 and 10), and the scattered silver polar ice field climate (the temperature of each month is below 0).

The boreal zone refers to the astronomical high-oppulse latitude zone, between 66°34' and 90° north and south latitudes. The northern and southern arctic zones each span latitude 23°26', and together they cover 8.3% of the surface area. The sun altitude angle is small, and there is no summer all year round.

There is a polar day and night phenomenon, the duration of which is one day in the polar circle and half a year at the pole. This area is located within the polar circle of the earth, and the maximum solar altitude angle at noon in a year is only 46°52, and there are polar day and polar night phenomena.

The north of the Arctic Circle is the boreal zone, and the south of the Antarctic Circle is the boreal zone. The temperature in the cold zone is low, and the length of day and night varies the most, and there is no obvious change in the four seasons. The boreal zone covers 10% of the Earth's total area.

The climate is characterized by extreme cold, dryness, and strong winds. The Antarctic continent is located alone at the southernmost point of the earth, and more than 95% of the Antarctic continent is covered by extremely thick ice and snow, known as the "white continent".

The climatic characteristics of the polar regions are ( ).

a.Severe cold, little rain, drought.

b.Bitterly cold, windy, and rainy.

c.Cold, gale, heavy snow.

d.Bitterly cold, dry, gale.

Answer: dThe cold climate of Antarctica and the Arctic Ocean and the ocean and land that surrounds them. In the Northern Hemisphere, the northern boundary where trees grow can be used as the southern boundary of the polar climate. In most of the polar climate zones of the Northern Hemisphere, permafrost waters are surrounded by continents.

In winter, there is no solar radiation in the polar night. The sun does not set all day during the polar day in the summer half of the year, but the reflectivity of ice and snow is strong. The heat obtained from solar radiation is not enough to melt the snow and ice, so the summer temperature is still low. It can be summed up in four words: severe cold all year round.

Polar climate, also known as cold climate, is a general term for various types of cold climates, including ice field climate and tundra climate. The polar tundra climate is distributed in North America and the northern edge of the Eurasian continent, with low temperature, low water vapor in the air, and annual precipitation of about 200-300mm. The polar ice sheet climate occurs on several islands in Greenland, the Antarctic continent and the Arctic Ocean, with annual precipitation of less than 250 mm, strong winds, cold sleet and poor visibility all year round.

Polar climate characteristics:

There are two main types of polar climates: tundra and icesheet. The tundra climate is mainly distributed in the Arctic Ocean coast of the Eurasian continent and the North American continent, and the ice field climate is mainly distributed in the Antarctic Huai Continent and Greenland Island in the Northern Hemisphere.

The polar climate is the coldest of the world's climate types, especially the ice sheet climate.

The main characteristics are extremely cold temperature, scarce precipitation, and abundant and heavy winds. Generally, the average temperature of the hottest month is below 0 degrees Celsius, and the precipitation is very small, even less than that in many desert areas, but because the evaporation is smaller and less than the precipitation, it can be regarded as the wetland with the least precipitation in the world, with an average of more than 200 windy days per year.

Polar climate:

Polar climate, also known as cold climate, is located in high latitudes and is a general term for various cold climates. The regions of Eurasia, the northern part of the North American continent, and Antarctica are typical of this climate. Polar climates include two types: icefield climate and tundra climate.

The ice sheet climate is distributed on the Antarctic continent and some islands in the Arctic Ocean, which are cold all year round, and the ground is thick with ice and snow. The tundra climate is distributed in the northern margins of the Eurasian continent and the North American continent, where there is no winter and no summer, and there are lower plants such as mosses and lichens on the ground. These two climate types have something in common:

It is cold all year round, especially in the icefield areas, which are covered in snow and ice almost all year round.
