When is the air pressure and humidity in the weather, everyone feels most comfortable.
Because the total amount of atmosphere on the earth is basically unchanged, when the temperature in one area increases, it is often accompanied by the temperature decrease in another area, which makes it possible for the air in high temperature to spread to low temperature. The result of diffusion is often that the air pressure at high temperature is lower than that at low temperature. When we live in the northern hemisphere, it is the summer that receives the most solar heat, and the southern hemisphere is the winter that receives the least solar heat. At this time, because the air in the northern hemisphere will spread to the southern hemisphere, the air pressure in the northern hemisphere is lower than that in the southern hemisphere. However, because the total amount of atmosphere is basically unchanged, the pressure in the northern hemisphere will be lower than the standard atmospheric pressure, and the pressure in the southern hemisphere will of course be higher than the standard atmospheric pressure. Similarly, air diffusion in the opposite direction will make the pressure in the northern hemisphere higher than the standard atmospheric pressure in winter. So in the northern hemisphere, the air pressure in winter will be higher than that in summer.
