Arab Weather - Air pressure is one of the elements of both weather and climate, and it is the one that mainly controls the behavior of the weather and the nature of the climate. The air pressure is affected by several factors and has fixed systems in the ball that do not change. All this can be learned through the article.

What is the barometric pressure?

It is the weight of the column of air located on a unit area of 1 cm² in any area on the surface of the earth, so that the weight of the column of air in fact represents the pressure group of the gases that it consists of in constant proportions. The atmospheric pressure is measured in millibars and is used to measure the atmospheric pressure of the mercury barometer, the metal barometer, and the barograph.

What are the factors affecting the rise and fall of air pressure?

Atmospheric pressure is affected in several things, and perhaps the most important of them are:

Temperature : Atmospheric pressure is mainly affected by temperatures. When the temperature rises, the air heats up and expands, and thus its density decreases. The air pressure decreases when the humidity levels are fixed in the air, and the exact opposite happens in cold air. When the temperature drops, the air shrinks, its density increases and becomes heavier in weight. Consequently, the pressure rises, provided the moisture levels remain constant.

Humidity : Atmospheric pressure is affected by humidity because moist air is lighter than dry air according to its temperature. When the humidity levels in the air, its density decreases and thus the atmospheric pressure decreases and vice versa.

Terrain : The atmospheric pressure is affected greatly in the terrain. The higher the area above sea level, the weight of the column of air falling from the top decreases, and consequently the atmospheric pressure is low, while the atmospheric pressure is high in low places as a result of the increase in the weight of the falling air column, which leads to a rise in pressure.

Specific temperature difference between land and water .

Atmospheric pressure has major ranges distributed around the world, namely:

Low equatorial pressure.

High orbital pressure.

Low sub-polar pressure.

High polar pressure.

Low air pressure is symbolized by (L) or (_)

The symbol for high air pressure is (H) or (+).
