A pressure system is a region of the Earth's atmosphere where air pressure is a relative peak or lull in the sea level pressure distribution.The surface pressure at sea level varies minimally, with the lowest value measured 870.0 hectopascals (25.69 inHg) and the highest recorded 1,085.7 hectopascals (32.06 inHg).ain articles: Low-pressure area and Cyclone. A low-pressure area, or low, is a region where the atmospheric pressure at sea level is below that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in upper levels of the troposphere.
Pressure and stress have the same units: pounds per square inch (psi) or newtons per square meter (N/m^2) also known as pascal (Pa). Pressure is a force per unit area typically used inside a fluid (liquid or gas) and is the same in all directions at a point inside the fluid. Stress is also force per unit area but is typically used inside solids. The difference is that the stress can be different in different directions inside the solid.
