Is it dry in summer or winter?

2. The temperature is high in summer, and the water vapor is not easy to liquefy, and it is distributed in the air as a gas, so the air humidity is high. In winter, even if there is water vapor in the air, it will liquefy into water because the temperature is too low, so the air will become dry.

The higher the temperature of air, the higher its capacity of containing water vapor (water vapor is different from water vapor). Although water vapor can react with some components in the air (such as salt in suspended dust) or be absorbed by porous particles, these processes or reactions account for a small proportion. On the contrary, most water vapor can be dissolved in the air.
