What happens to Arctic sea ice in winter?
2022年9月23日 · The 2020 study concluded that, even under a low-emission scenario, Arctic sea ice is likely to melt away completely in September by the year 2100. Under the same scenario, however, Arctic sea ice would survive in the winter months. Under a high-emission scenario, sea ice may disappear from the Arctic in all months before the year 2100.

Arctic Weather and Climate - National Snow and Ice Data Center
Almost all precipitation in the central Arctic Ocean and over land falls as snow in winter. However, rain can occur on rare occasions during winter in the central Arctic Ocean when warm air is transported into this region. Snow also falls in summer. More than half of the precipitation events at the North Pole in summer are snowfall.
