GRAVITATION The mutual attraction between two masses of matter. The rotation of the earth and the atmosphere modifies this attraction to produce the field of gravity.
Gravitational force: The product of mass and gravitational acceleration.
Gravity: The mutual attraction between two or more objects.
where g is gravitational acceleration, z is height, θv is virtual potential temperature, Tv is the virtual temperature, (U, V) are the horizontal Cartesian wind components from the west and the south, primes denote deviations from mean values, ...
Gravity wave (gravitational wave) A wave disturbance in which buoyancy (or reduced gravity) acts as restoring force on parcels displaced from hydrostatic equilibrium.
"Newton's Law of Gravitation"
1. The force by which a body attracts another body increases with the mass of the object it attracts.
2. The bigger the object, the stronger the call of gravity.
3.
This force on the earth and in the atmosphere due to the rotation about the earth's axis is incorporated with the field of gravitation to form gravity.
Atmospheric PressureThe pressure exerted by the earth's atmosphere at any given point, determined by taking the product of the gravitational acceleration at the point and the mass of the unit area column of air above the point.
Distinction is made between free convection (gravitational or buoyant convection), motion caused only by density differences within the fluid; and forced convection, ...
Atmosphere The envelope of air surrounding the earth and bound to it more or less permanently by virtue of the earth's gravitational attraction.
As is well known, an uneven distribution of gravitational forces in the vertical can give rise to convective instability.
See Newton's law of universal gravitation and laws of motion. orbits--only elliptical ones--determined by gravitational perturbations and other factors.
The pressure exerted by the atmosphere as a consequence of gravitational attraction exerted upon the “column' of air lying directly above the point in question.
For example, the large gravitational force of the giant planet Jupiter is able to retain light gases such as hydrogen and helium that escape from lower gravity objects.
However, air parcels displaced along certain sloped, or "slantwise" trajectories may attain positive buoyancy due to a unique combination of gravitational and centrifugal forces.
A measure of the weight of an entire air column of unit area cross section above the barometer, as a consequence of gravitational attraction, or equivalently, the force exerted by molecules of air acting on a unit area of any surface.
atmosphere: air enveloping earth due to earth's gravitational pull. Can be divided into layers radiating out from the surface in the following order- troposphere, stratosphere, mesosphere, thermosphere.
BAROMETRIC PRESSURE: The atmospheric pressure at a given point due to the gravitational force on the column of air above it.
BAUD: A unit used in describing the rate of character transmission and equal to approximately one bit per second.
Astronomic Tide: Periodic variation of the oceans, caused by gravitational forces of the stars mainly from the moon and sun.
Atmosphere: The mass of air involving the Earth.
Lunar Atmospheric Tide
Atmospheric tide due to the gravitational attraction of the Moon, the main component of which is a 12-lunar hour component, as in the oceanic tides.
Tide - The regular rise and fall of the Earth's oceans caused by the actions of the moon's and sun's gravitation acting on the rotating Earth.
Tidal Range - The difference in water level between high tide and low tide at a given place.
Atmosphere The envelope of gases that surround a planet and are held to it by the planet's gravitational attraction. The earth's atmosphere is mainly nitrogen and oxygen.
atmospheric pressure (also called barometric pressure)—The pressure exerted by the atmosphere as a consequence of gravitational attraction exerted upon the “column' of air lying directly above the point in question.
The pressure exerted by the earth's atmosphere at any given point, determined by taking the product of the gravitational acceleration at the point and the mass of the unit area column of air above the point.
Atmospheric Radiation ...
Morning glories result from perturbations related to gravitational waves in a stable boundary layer. They are similar to ripples on a water surface; several parallel morning glories often can be seen propagating in the same direction.
In the case of the earth, it is held more or less near the surface by the earth's gravitational attraction. The divisions of the atmosphere include the troposphere, the stratosphere, the mesosphere, the ionosphere, and the exosphere.
GRAVITY- The attraction of two masses to one another. Large masses have higher values of gravitational accelerations than lighter masses.
Atmosphere - The mass of air surrounding the earth and bound to it more or less permanently by the earth's gravitational attraction.
There is also the gravitational force -ρg, but this is usually balanced by buoyancy; when it is not, it must also be included. If the path of the air is curved, it is also subject to the centrifugal force v2/r.
Tidal currents are caused by gravitational interactions between the sun, moon, and earth and are a part of the same general movement of the sea that is manifested in the vertical rise and fall, called TIDE.
Tide PredictionThe computation of tidal highs and lows at a given location resulting from the gravitational interactions between the earth and primarily the moon and sun.
