What is the climate type in Antarctica?

1) Climate zone of continental ice zone: The interaction between seawater and atmosphere in continental ice zone is complex. Under the influence of different meteorological factors such as temperature, wind and clouds, seawater affects the heat balance in this area through the significant change of sea ice reflectivity and the heat exchange between sea ice and the atmosphere, thus causing the change of atmospheric circulation [2]. In the warm season, due to the influence of the wind, most of the sea ice is broken into large pieces of floating ice, which drift with the wind. Many sea areas become ice-free in summer. In the sea ice area, the lower the annual average temperature in coastal areas, the larger the area covered by sea ice.

2) Coastal climate: The coastal area is the area with the greatest weather and climate change in the Antarctic continent. This area is not only affected by the polar low pressure belt, but also attacked by the strong cold air in the inland area. At the most Leng Yue, the warm air mass in the north can also invade the Antarctic coastal areas through low-pressure activities, which makes the local temperature change obviously, and the temperature can rise to 6~7℃. This region is also the region with the highest wind speed in the Antarctic continent, with an average annual wind speed of 8.2m/s.

3) Climate of inland areas: The inland areas are dominated by plateaus, and the inland central part of the East Antarctic continent is one of the driest areas in the world, known as the "white desert".

Four species of Antarctic organisms

Antarctica is a continent covered with hard ice and snow. The harsh natural environment makes it the only continent without human distribution, but Antarctica has a rich and colorful animal world.

Penguin is one of the most representative animals in Antarctica. There are seven common penguins in Antarctica: Emperor Penguin, Adelie Penguin, Golden Penguin (also known as Papua Penguin), Hooded Penguin (also known as Antarctic Penguin), Emperor Penguin (also known as King Penguin), Loki Penguin and Flash Penguin. Although there are not many species, they are abundant and widely distributed, accounting for more than 90% of Antarctic birds.
