Is the air pressure high or low in autumn?

The air pressure is high in autumn.

In autumn, the air pressure rises, the weather turns cool, the rain becomes scarce, the water evaporation accelerates, and the air dryness increases. Of course, it also has a certain relationship with the physiological cycle changes of plants. Due to the clear weather after autumn, it is commonly known as the crisp air in autumn, the air pressure rises, the water evaporates quickly, and the air becomes dry.

The change of atmospheric pressure is related to altitude. Atmospheric pressure is produced by gravity in the atmosphere. The higher the ground, the thinner the atmosphere, and the smaller the atmospheric pressure should be. However, because the air density related to the gravity received by the atmosphere varies unevenly with height, the atmospheric pressure decreases unevenly with height. Change with height: atmospheric pressure decreases with the increase of height.

The change of atmospheric pressure is also related to the weather. At different times, the atmospheric pressure in the same place is not exactly the same. The density of water vapor is less than that of air. When there is more water vapor in the air, the air density will become smaller and the atmospheric pressure will also decrease.

The change of air pressure in the extended data is related to altitude. Atmospheric pressure is produced by gravity in the atmosphere. The higher the ground, the thinner the atmosphere, and the smaller the atmospheric pressure should be. However, because the air density related to the gravity received by the atmosphere varies unevenly with height, the atmospheric pressure decreases unevenly with height. Change with height: atmospheric pressure decreases with the increase of height.

The change of atmospheric pressure is also related to the weather. At different times, the atmospheric pressure in the same place is not exactly the same. We know that the density of water vapor is less than that of air. When there is more water vapor in the air, the air density will become smaller and the atmospheric pressure will also decrease.
