What are the climatic characteristics of Greenland?

Greenland's polar climate is cold, affected by the Gulf Stream, and the temperature only rises slightly in the southwest. There is a continuous layer of cold air over the cold inland of the island, and there is often a low-pressure air mass moving from west to east above the cold air, which makes the weather changeable, sometimes sunny and sometimes snowy. In winter (65438+1October), the average temperature in the south is MINUS 6℃, and the average temperature in the north is MINUS 35℃. The average temperature in the southwest coast in summer (July) is 7℃. The average summer temperature in the northernmost part is 3.6 degrees Celsius. The average temperature in central Leng Yue is minus 47℃, and the absolute minimum temperature reaches minus 70℃, making it the second "cold pole" on earth after Antarctica. The average annual precipitation decreased from 1900 mm in the south to about 50 mm in the north. . Greenland is the largest island in the world, with an area of 2 166000 square kilometers. About four-fifths of the island is in the Arctic Circle. The annual temperature in Greenland is below 0℃, and the coldest in some places can reach -70℃.

Standing on the green land, chanting "Thousands of miles of ice, Wan Li snow" can find a full feeling. All kinds of icebergs and glaciers have become the wonders of Greenland, and they have developed rich associations with them. In the northeast of North America, between the Arctic Ocean and the Atlantic Ocean, the whole island covers an area of 265,438+066,000 square kilometers, with a coastline of more than 35,000 kilometers. It is the largest island in the world, larger than the total area of Western Europe and Central Europe, so some people call it the Greenland subcontinent.

Greenland is not only the largest island on earth, but also an island covered with ice and snow in most areas (about 83.7%). Greenland's continental glaciers (or ice sheets) cover an area of 1.8 1.3 million square kilometers, and their average ice thickness reaches 2300 meters, which is similar to the Antarctic continental ice sheet. Greenland contains 3 million cubic kilometers of ice and snow, accounting for 5.4% of the world's total fresh water. If all the ice and snow in Greenland melt, the global sea level will rise by 7.5 meters. And if all the ice and snow in Antarctica melt, the global sea level will rise by 66 meters.

The largest island in the world, with an area of 2 166086㎞? In northeastern North America, between the Arctic Ocean and the Atlantic Ocean. It reaches Piridi in the north and Cape Farwell in the south, with a distance of 2,574 kilometers, the widest point of about 1.290 kilometers and the coastline of more than 35,000 kilometers. Nuuk, the capital of Denmark, has a population of about 57 100.

In fact, this island is not as full of spring as its name. Geographically, Greenland belongs to a high latitude area. Its northernmost Maurice Jessup is located at 83 39' north latitude, while its southernmost Fawell is located at 59 46' north latitude, with a length of about 2,600 kilometers from north to south, which is equivalent to the distance from the northern end of the European continent to Central Europe. The easternmost northeast corner is located at1139' west longitude, and the west corner of Alexandria is located at 73 08' west longitude, with a cold and snowy climate.

The ice-free zone in Greenland is 34 1700㎞? But most of the north coast and the east coast are almost inaccessible cold wasteland. The living area is about 6.5438+0.5 million square kilometers, mainly distributed in the south of the west coast. The island has a vast depth from north to south, and the climate difference between regions is significant. Greenland, located in the Arctic Circle, has extreme day and night phenomena unique to the polar regions.

Residents are mainly distributed in the west and southwest, with Inuit (Eskimos) as the majority. There is the largest fjord in the world on the west coast, which cuts inland for 322 kilometers. Most residential areas, including its capital, St. Gotha, are located here, with a population of about 6.5438+0.2 million. Two-thirds of the island is north of the Arctic Circle, with a cold climate, and only the southwest has no permafrost. About 4/5 of Greenland's land is covered with ice, the thickest in the middle reaches is 34 1 1 m, and the average thickness is close to1500m. It is a modern giant continental glacier second only to Antarctica.
