What is another term for the pressure exerted by the weight of air and water vapor on the earth's surface?

Barometric pressure refers specifically to the weight of the atmosphere above a given point, which includes both air and water vapor. This pressure is a crucial concept in various fields, including meteorology and fluid dynamics, as it directly influences weather patterns and the behavior of gases and liquids.

Barometric pressure is measured using a barometer and is typically expressed in units such as millimeters of mercury (mmHg) or inches of mercury (inHg). As the altitude increases, barometric pressure decreases because there is less air above pressing down.

Hydraulic pressure pertains to fluids in motion or at rest, specifically within a confined space such as a pipe, and does not account for atmospheric conditions. Atomic pressure is not a standard term in fluid mechanics or atmospheric science and may refer to concepts related to particle physics. Dynamic pressure relates to the kinetic energy of a moving fluid and is calculated based on the velocity and density of the fluid, which again is distinct from the pressure associated with the weight of air and water vapor.
