Sentences with phrase «hydrostatic balance of»
People who know about this scratch their heads here, because it is a principle which can be important in stars, but applied to Earth just describes the hydrostatic balance of the atmosphere.

Osmolar, hydrostatic, and oncotic pressures all regulate the balance of fluid movement.
So, we are now ready to pull all that together in order to show how a planetary atmosphere uses convective overturning to neutralise the effect of radiatively active materials of any type so that hydrostatic balance can be maintained whatever fate throws at it.
Kinetic energy at the surface acting via conduction and convection supplies the upward pressure gradient force which offsets the downward force of gravity in order to constantly hold the mass of an atmosphere off the surface in hydrostatic balance.
The hydrostatic equation is the vertical component of the momentum equation (Newton's equation of motion) for the fluid parcel when the forces are in perfect balance and the net acceleration = 0.»
To find the expression for the hydrostatic balance, we first note that atmospheric surface pressure is due to the weight of the entire atmospheric column above.
In fact, a gas with a DALR is a fairly special case of the many «equilibria» one can reach in the specific limit of hydrodynamic relaxation (only) to a state of hydrostatic balance neglecting the much slower thermal relaxation that eventually makes the gas isothermal.
The adiabatic lapse rate is within the hydrostatic balance because of the properties of gases which create the pressure.
In a neutral, unheated atmosphere, once one waits a very long time, there is no more movement of air; it achieves hydrostatic equilibrium, force balance.
All of them are hydrostatic — in perfect force balance — by construction, they satisfy the differential equation above for the balance of buoyant forces in a fluid.
The second one is that in hydrostatic equilibrium, where the vertical gradient of total air is balanced by gravity, the dynamic power is only produced by horizontal pressure gradients (i.e. q = — u. ∇ p).
The heating (e.g. latent heating is created by change of state of water and thus impacted by humidity) is redistributed until hydrostatic balance is restored.
As soon as a global climate model readjusts a vertical column to unphysically alter the large scale solution in order to maintain hydrostatic balance (overturning due to unrealistic heating parameterizations necessitate this adjustment), there is no mathematical theory that can justify the nature of the ensuing numerical solution.
Regarding the origin, EU is more closely related to the total internal kinetic energy of the atmosphere, which — according to the virial theorem — in hydrostatic equilibrium balances the total gravitational potential energy.
