Why is the air particularly dry in winter?

The reason why the air is particularly dry in winter:

This involves a concept of saturated vapor pressure. When water evaporates continuously, the pressure of gas phase above the water surface, that is, the pressure of water vapor, increases continuously. But when the temperature is constant, the vapor pressure will eventually stabilize at a fixed value, and the vapor pressure at this time is called the saturated vapor pressure of water at this temperature. When the saturated vapor pressure is reached, the evaporation rate and condensation rate of water are the same. The characteristic of saturated vapor pressure is that it increases with the increase of temperature. ?

Generally speaking, the higher the temperature, the more moisture produced by evaporation in the air, and the greater the humidity in the air. or vice versa, Dallas to the auditorium The lower the temperature, the less moisture produced by evaporation in the air and the less humidity in the air. ?

From the point of view of energy, the higher the temperature, the more energy water molecules gain, and it is easy to leave the water surface and evaporate into the air.

When the temperature is low in winter, the water in the air condenses into tiny ice crystals, or falls on the ground or adheres to the surface of objects, so there is no water in the air, negative ions decrease, and the air becomes dry accordingly.
