What is the main reason for the severe cold along the Arctic Ocean?

The Arctic Ocean coast has a high latitude, the annual average noon sun height is small, and there is a long polar night in winter, so solar radiation is weak; solar radiation passes through a long atmospheric path before reaching the ground, and the atmosphere weakens solar radiation. The effect is strong, and less solar radiation reaches the ground; the ice and snow area along the Arctic Ocean is large, and the reflectivity of solar radiation is high. The ground absorbs less heat, transfers less heat to the atmosphere, and the temperature is low; there are many sunny days, and the atmospheric reverse radiation is also weak. , less heat is returned to the ground, and less heat is stored in the ground and atmospheric systems; in winter, the heat capacity of the land along the Arctic Ocean is small, and the cooling rate is large, which intensifies the cold.
