Sentences with word «diabatic»

The tendency for clouds to form where air is going up creates an asymmetry of diabatic heating in a wave (see figure below).

Essentially, the adiabatic and diabatic loops must always match each other on any given planet at equilibrium because they are then of equal size and run at equal speed but are of opposite sign.

As long as the AAL is a closed loop and kept independent of the Solar Diabatic Loop (SDL) then system equilibrium is maintained however high the surface temperature might rise.

I call this the Solar Diabatic Loop (SDL)

Here is a simplified summary of the nature of, and differences, between diabatic and adiabatic processes.

I have encountered much confusion about the relevance of so called diabatic and adiabatic processes in the minds of both alarmed proponents of Anthropogenic Global Warming (AGW) and in the minds of many sceptics.

Global climate models (GCMs) tend to simulate too few EETCs, perhaps partly due to their coarse horizontal resolution and poorly resolved moist diabatic processes.

Excessively deep equivalent depths suggest that these models may not have a large enough reduction in their «effective static stability» by diabatic heating.

However, we can measure the temperature and estimate how it changes as a result of air flowing over an area, and then calculate the «leftover» residual temperature tendency to get an idea of how diabatic processes (i.e. convection and radiation) are heating the atmosphere.

This study investigates the features of eastward extension of the South Asian high (SAH) and its connection with diabatic heating and rainfall over eastern Asia on subseasonal time scales.

A further complication is that regional diabatic heating results in nonlinear long - distance communication of convergence and divergence fields, often referred to as teleconnections.

The heterogeneous diabatic heating can modulate the gradient in horizontal pressure field and atmospheric circulations, thus altering the regional climate...»

Large - scale topography and diabatic anomalies are introduced to modify and concentrate the synoptic variability, establishing a recipe for a localized storm track.

Rosenfeld (2000) refers to these kinds of aerosol forcings as thermodynamic forcing because the spatial patterns of diabatic heating are changed.

Idealized horizontal profiles of vertical velocity (left) and diabatic heating (right) to illustrate how convective heating is asymmetric in an atmospheric wave.

No process is perfectly adiabatic so there will always be some diabatic energy exchange in or out of the moving parcel but here we are only concerned with the adiabatic portion.

Any work done against surrounding molecules would be diabatic and not adiabatic.

When clouds form, the diabatic heating from condensed water vapor warms the air.

With regard to the diabatic process the exchange of radiation in and out reaches thermal equilibrium relatively quickly (leaving Earth's oceans out of the scenario for current purposes) and once the temperature rise within the atmosphere has occurred then equilibrium has been achieved and energy in at TOA will match energy out.

An attempt is made to reconcile the diabatic and adiabatic processes within a planetary atmosphere and in doing so show how changes in the radiative characeristics of constituent molecules in an atmosphere might not have an effect on the equilibrium temperature of the atmosphere and of the surface beneath it.

The more the time that is taken by the adiabatic process the higher the temperature that the surface and atmosphere can reach without upsetting the equilibrium of the diabatic radiation exchange at TOA.

The prime contributor to diabatic heating is the sun.»

Essentially, an adiabatic process is one where temperature changes can occur without addition or removal of energy and a diabatic process is one where temperature changes can only occur as a result of the addition and or removal of energy.

i) A diabatic effect whereby solar energy arriving at TOA penetrates into and through the atmosphere, increases the temperature of the surface and of air within the atmosphere and then leaves again.

(i) If one increases GHGs to slow down energy flow through the diabatic loop thereby warming that loop there will be an increase in PE relative to KE within the adiabatic loop instead of a change in the constant.

Diabatic temperature changes on the other hand can occur in the form of diabatic heating or diabatic cooling.

The exchange of energy between surface and Space is a diabatic process involving the exchange of radiation.

The adiabatic process, being mechanical rather than radiative, takes longer than the diabatic process.

Thus the effect of changing the proportion of GHGs in the diabatic loop is to produce an equal and opposite thermal effect in the adiabatic loop which leaves equilibrium temperature constant.

(ii) If one decreases GHGs to speed up the energy flow through the diabatic loop thereby cooling that loop there will be a reduction in PE relative to KE within the adiabatic loop instead of a change in the constant.

Quantify the magnitude, location, and physical mechanisms associated with interior diapycnal mixing in the ocean, which contribute to the diabatic AMOC, and evaluate the realism of current GCMs in this regard.

All it would take for the Makarieva Effect to work, would be for a rising moist air mass to be more diabatic than a dry air mass.

Quantify the magnitude, location, and physical mechanisms associated with interior diapycnal mixing in the ocean, which contribute to the diabatic AMOC, and evaluate the realism of current ocean GCMs in this regard.

For example, see The Diabatic and Nonlinear Aspects of the El Nino - Southern Oscillation: Implications for its Past and Future Behavior (Sun 2009).

In the mixed layer and upper - mode - water regions, the divergent eddy fluxes are manifestly across isopycnals and so have a diabatic effect.
