At some point, normally ~ 30 deg. North/South, the increase in surface pressures reaches a maximum, marking a belt of subtropical high pressure. Sinking air is dry and characterized by a lack of clouds and precipitation. These regions of subtropical high pressure systems are known for their tranquil weather.

Why are there global high and low pressure belts on the earth? Uneven warming by the sun due to Earth's tilt. The high heat areas are closer to the equator and heat rises taking pressure off the earth causing the low pressure area. The other way around cool air sinks causing a high-pressure area on the earth surface.

Typically, once a storm has moved through a region, the barometric pressure should begin to rise again. High Pressure An area of high pressure occurs when the atmosphere over a given location is heavier, which forces the air above down, creating a divergence as the air moves out, away from the center of the high-pressure area.

Aug 14, 2019· Most of the Earth's crust is made from a rock called basalt. Where two plates meet due to sea-floor spreading, the high density of basalt causes it to sink – or subduct – into the Earth's interior. As these basaltic rocks travel deeper into the Earth they are exposed to higher pressures and temperatures and undergo various reactions.

Your question is specific to the pressure change with depth in the earth.

Surface pressure is the atmospheric pressure at a location on Earth's surface (terrain and oceans). It is directly proportional to the mass of air over that location. For numerical reasons, atmospheric models such as general circulation models (GCMs) usually predict the nondimensional logarithm of surface pressure.
