Why does weather change affect atmospheric pressure?

Every ten meters above sea level, the atmospheric pressure drops (100pa).

The air pressure in winter is higher than that in summer.

The air density is higher when the temperature is low, so the temperature is low and the air pressure is high in winter.

The air pressure in rainy days is lower than that in sunny days.

On rainy days, the atmosphere can't bear the weight of raindrops falling to the ground because of the low air pressure.
