Sentences with phrase «temperature towards equilibrium»

Also could you tell me if the increase in temperature towards equilibrium is expected to be linear.

Not exact matches

When you say «If the oceans are warming at all, or if the net ice melting is positive, we are not in equilibrium» it suggests that you see temperatures inexorably rising towards an equilibrium.

As atmospheric temperatures increase, therefore, heat transfer into the oceans increases as the system tends towards a new equilibrium temperature.

Radiative equilibrium at small LW optical thickness occurs when the whole atmosphere has a temperature such that the Planck function is about half of that of the surface (a skin temperature), whereas at larger LW optical thicknesses, the equilibrium profile has a signficant drop in the Planck function through the atmosphere, approaching half the OLR value at TOA and approaching the surface value towards the surface — of course, convection near the surface will bring a closer match between surface and surface - air temperatures.

Depending on meridional heat transport, when freezing temperatures reach deep enough towards low - latitudes, the ice - albedo feedback can become so effective that climate sensitivity becomes infinite and even negative (implying unstable equilibrium for any «ice - line» (latitude marking the edge of ice) between the equator and some other latitude).

Starting with zero atmospheric LW absorption, adding any small amount cools the whole atmopshere towards a skin temperature and warms the surface — tending to produce a troposphere (the forcing at any level will be positive, and thus will be positive at the tropopause; it will increase downward toward the surface if the atmosphere were not already as cold as the skin temperature, thus resulting in atmospheric cooling toward the skin temperature; cooling within the troposphere will be balanced by convective heating from the surface at equilibrium, with that surface + troposphere layer responding to tropopause - level forcing.)

For an optically thick stratosphere, for full equilibrium, the same temperature profile is compressed towards TOA, except where the flux from the troposphere + surface requires some deviation.

As more optical thickness is added to a «new» band, it will gain greater control over the temperature profile, but eventually, the equilibrium for that band will shift towards a cold enough upper atmosphere and warm enough lower atmosphere and surface, such that farther increases will cool the upper atmosphere or just that portion near TOA while warming the lower atmosphere and surface — until the optical thickness is so large (relative to other bands) that the band loses influence (except at TOA) and has little farther effect (except at TOA).

EOD makes no difference to equilibrium temperature it only makes a difference in the speed at which the system moves towards equilibrium.

The process of such evaporation and then condensation together with those other weather processes is an express route to get heat energy from ocean to surface to atmosphere to space and the bigger the temperature differential between ocean surface, atmosphere and space the faster they must all work to move the atmosphere back towards a temperature equilibrium.

However what I do say is that if other factors alter albedo (or any other component of the global energy budget) then the jets will move in response to that other forcing in order to try to move back towards equilibrium between the temperature of the ocean surface and the temperature at the tropopause.

No, the ocean thermocline never reaches a state of thermodynamic equilibrium because there is a new supply of thermal energy each day and that energy must be diffused downwards and then towards the poles, so there is continual energy movement and the temperature gradient is always there in the thermocline, so how could it possibly be thermodynamic equilibrium?.

Radiative equilibrium does drive towards an isothermal state, but mixing goes towards an isentropic state, which is a recognized term indicating constant potential temperature (also dry adiabatic) because the log of potential temperature is basically the entropy in thermodynamic terms.

As per my posts above, it is possible for DLR to increase more than evaporation, and so the warming from the DLR beats the cooling from evaporation, leading to a warming whereby the system is moving towards equilibrium by increasing temperature and hence increasing sensible heat flux and emitted longwave radiation.

To move towards equilibrium, either R and E increase (R and E being functions of temperature), L increases or all three increase.

The temperature of the Earth will tend to move towards equilibrium with the forcings, so that the same amount of energy enters and leaves (forget for the moment possible multiple equilibria).
