Pressure-gradient force — The pressure gradient force is not actually a force but the acceleration of air due to pressure difference (a force per unit mass). It is usually responsible for accelerating a parcel of air from a high atmospheric pressure region to a low… … Wikipedia
Pressure gradient — In atmospheric sciences (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure changes the most… … Wikipedia
gradient wind — /wind/ a wind with a velocity and direction that are mathematically defined by the balanced relationship of the pressure gradient force to the centrifugal force and the Coriolis force: conceived as blowing parallel to isobars. Cf. geostrophic… … Universalium
gradient wind — Any horizontal wind velocity tangent to the contour line of a constant pressure surface or an isobar. This movement of air is to the result of a combination of three forces: pressure gradient force, geostrophic force, and cyclostrophic force. In… … Aviation dictionary

Low-pressure area — This depiction of the Hadley cell shows the process which sustains low pressure areas. Diverging winds aloft allow for lower pressure and convergence at the Earth s surface, which leads to upward motion. A low pressure area, or low , is a region… … Wikipedia
Low pressure area — A low pressure area, or low , is a region where the atmospheric pressure is lower in relation to the surrounding area. Tropical storms, extratropical cyclones, subpolar cyclones, and subarctic cyclones are called low pressure cells.Lows are… … Wikipedia
Force — For other uses, see Force (disambiguation). See also: Forcing (disambiguation) Forces are also described as a push or pull on an object. They can be due to phenomena such as gravity, magnetism, or anything that might cause a mass to accelerate … Wikipedia

Force-free magnetic field — A force free magnetic field is a type of field which arises as a special case from the magnetostatic equation in plasmas. This special case arises when the plasma pressure is so small, relative to the magnetic pressure, that the plasma pressure… … Wikipedia
pressure — 1. A stress or force acting in any direction against resistance. 2. (P, frequently followed by a subscript indicating location)In physics and physiology, the force per unit area exerted by a gas or liquid against the walls of its container or… … Medical dictionary
