1 1, polar tundra climate:

Reason: its latitude is close to or within the polar circle, so the extreme phenomenon of day and night is obvious. The temperature is very low at night, but the adjacent ocean is slightly higher than the subtropical continental climate.

Climate characteristics: it is winter all year round, and the average monthly temperature is about 0℃~ 10℃ only for14 months in a year. The temperature is very low at night, but the adjacent ocean is slightly higher than the subtropical continental climate. The average temperature in Leng Yue is between minus 20 and 40 degrees. The average temperature in the hottest month is about 1 ~ 5℃. In July and August, the temperature can still drop below 0℃ at night.

Climatic characteristics: It is extremely cold all year round, with the monthly average temperature below 0℃ and the lowest annual average temperature in the world. There is a long period of extreme day and night in a year. The annual precipitation is less than 250 mm, which is dry snow and will not melt, forming a thick ice sheet for a long time. Long-term gale, cold wind with snow, poor visibility.

Distribution: Greenland, Antarctic continent and several islands in the Arctic Ocean. It is the source of ice air mass and Antarctic air mass.

Extended data:

The factors that affect the climate are:

1, solar radiation factor, underlying surface factor, atmospheric circulation factor, human activity factor. Solar radiation factor is the basic power source of climate. Such factors include: latitude factors, etc. Underlying surface factors play a very important role in climate formation. These factors include ocean currents, ground vegetation, topography and geology.

2. The atmospheric circulation factor itself is an integral part of the climate, which has a direct impact on the formation of a certain climate. The main factors are: the average state of air mass, the average state of air flow and so on.

3. The influence of geographical factors on climate formation is manifested in the shape of the earth, the movement of the earth, the distribution of land and sea, topography, airflow and ocean currents. The influence of geographical factors on climate formation can be mainly attributed to radiation factors.

4. Latitude factor: the shape and movement of the earth.

Different geographical latitudes receive different heat, resulting in different climates; Generally, the higher the latitude, the lower the temperature; The equatorial region has the most precipitation, and the precipitation near the poles is the least. Near the Tropic of Cancer, there is more precipitation on the east coast of the mainland, and less precipitation on the west coast and inland.

5. Solar radiation is the heat source of the ground and atmosphere, and the difference of ground heat budget is an important reason for climate formation. Solar radiation is mainly influenced by latitude and

6, the earth's rotation, revolution, land and sea distribution, topography. For the whole earth, the balance of ground heat is almost zero, but for different regions, the heat received by the ground is different, which will have an impact on the formation of climate. At the same time, the ground continuously exchanges heat with the atmosphere after receiving heat, and each component in the heat balance process also has an important influence on climate formation.

7. Atmospheric circulation and weather system. Factors affecting climate include temperature, rainfall, air pressure and wind.

8. The effects of ocean currents on climate are mainly humidity and heat.

Warm current plays a role in warming and humidifying the climate in coastal areas. For example, the formation of maritime climate in western Europe directly benefits from the warm and humid North Atlantic ocean current.

The cold current plays a role in cooling and dehumidifying the climate in coastal areas. For example, the cold current on the west coast of the mainland (southern hemisphere) played a certain role in the formation of desert environment on the west coast of Australia and the Pacific coast of Peru.

9. Topography plays an important role in the formation of local climate. For example, the sunny slope effect and shady slope effect, windward slope and leeward slope effect in mountain climate. Generally speaking, the terrain mainly blocks and lifts the airflow.

There is more precipitation on windward slope and less precipitation on leeward slope in mountainous area. The influence of topography on climate formation is high altitude, less clouds, enhanced direct solar radiation, reduced scattered radiation, lower temperature and lower humidity. Different landforms have different effects on climate, and the plateau has obvious effects on climate.

10. Human activities: By changing the ground conditions, the local climate is affected. For example, artificial afforestation can improve the climate in some areas, and arbitrary logging will worsen the local climate. In addition, human activities will also form a heat island effect. Global warming is caused by human activities.
