Did you know that air has weight? That's right. Air has mass, which technically makes it exert some pressure on the ground and also on our heads! This force exerted by the air on the surface areas is calledatmospheric pressure, an importantclimatic element.
A very curious fact is that the atmospheric pressure it occurs with different intensities in different regions, that is, in some places, it is stronger; in others it is weaker. These differences in atmospheric pressure in different areas of the Earth's surface cause it to interfere in the behavior of climate.
Another important effect of atmospheric pressure is the occurrence of winds. They arise because the air moves to areas of lower pressure, so that, in addition to the winds, there is also the displacement of air masses, which alters the behavior of the climate in different parts of the planet.
What influences atmospheric pressure?
For the atmospheric pressure of any place to be high or low, there are a number of factors. The first one is the
altitude. In lower places, the column of air is larger, which makes the “weight” of the air to be higher. The opposite happens in higher altitude areas, such as mountain tops or mountainous regions, where air is lighter and scarcer. That is why, the higher the altitude, the lower the atmospheric pressure.In addition to the altitude, the temperatures also interfere with atmospheric pressure. In warmer locations, atmospheric pressure tends to be lower, as the air molecules are further apart from each other. On the other hand, when the environment cools down, atmospheric pressure decreases as the air molecules become more tightly packed together.
