Hint: The air around you has weight, and it presses against all that it contacts. That weight is called climatic weight, or pneumatic stress. Gaseous tension changes with the climate. High weight happens when cold air pushes down, typically bringing a fine climate. Low weight happens when warm air ascends to make mists and downpours.

Complete step-by-step solution:
The distribution of atmospheric pressure isn't uniform over the earth’s surface. It varies vertically moreover as horizontally.
A. Vertical Distribution: Air being a combination of gases is exceptionally compressible. Its thickness is, hence, most prominent at the lower layers, where it is packed under the mass of air above. Subsequently, the lower layers of the air have a high thickness and high weight. Interestingly, the higher layers are less packed and subsequently have a low thickness and low weight. The higher we go, the slenderer the air becomes, and consequently, the atoms are more diffused, and there is less weight because between subatomic space is more noteworthy.
B. Horizontal Distribution: The dissemination of climatic weight over the scopes is named as worldwide even dispersion. This dissemination is portrayed by the presence of particularly recognizable zones of homogeneous weight systems or 'weight belts'. On the world's surface, there are every one of the seven weight belts. The seven weight belts are the central low, the subtropical highs, the subpolar lows, and the polar highs. Aside from the central low, all other structures coordinating sets in the northern and southern halves of the globe.

Note: Factors dominant Pressure Systems: There are two main causes, thermal and dynamic, for the pressure variations leading to high and nonaggressive systems.
