Fresh snow has a high albedo, meaning it reflects up to 90% of the sun’s energy back into space. This prevents the ground from absorbing heat, keeping the surface temperature low.
Mongolia Summer Hot Winter Extreme Cold: Understanding the Seasonal Shift
Mongolia sits in the heart of Eurasia, a landlocked expanse where winter temperatures can plummet beyond -40 degrees Celsius. Acting as a巨大的热源 (a massive heat source) in the summer, it helps to pull in warmer air, but in the winter, it becomes a巨大的冷源 (a massive cold source).
The combination of these factors creates a climate that is not merely cold, but defined by a profound and penetrating winter. Factor Impact on Temperature High Latitude Lower solar angle, less intense solar energy Long Winter Nights Extended period of heat loss to space Elevation Thinner air holds less heat, generally colder Snow Cover and Albedo Effect Once the snow falls and blankets the landscape, it initiates a powerful feedback loop that reinforces the cold.

This system acts like a lid, pressing down with intense, dry cold and blocking the milder, moisture-laden air from the south. The buffering effect of oceans, which stabilizes coastal climates, is entirely absent.
