Sentences with phrase «equilibration time»

Here Isaac Held cautiously states that a 500 - year equilibration time is more appropriate while outlining the limitations of simple two - box models.

Finally, we note that the equilibration time of the δ13C of seawater is about 10 times longer than that of pCO2, potentially decoupling the δ13C of DIC from surface ocean nutrient and pCO2 values.

A very long tail can result with neither high ECS nor high equilibration time.

«c) the information content in the temperature and OHC series is not sufficient to allow accurate estimation of ECS and equilibration time; a flux response function with a very long tail (high ECS, high equilibration time) may give a result similar to the Schwartz exponential response function with a low ECS and low equilibration time.»

The accessibility of deep ocean heat to the climate system tells us that the equilibration time relevant to multidecadal climate sensitivity estimates is longer than an interval based on upper ocean measurements, and so sensitivity will be underestimated if only the shorter interval is used.

The published values for the GISS - E model are 0.75 deg / Wm2 (or 2.7 deg for a doubling of CO2) and a full equilibration time amounting to several hundred years.

Another issue is the use of an «equilibration time» even though the analysis shown in some papers indicates that it may not be meaningful, in that perturbation response time is not constant but scales with time.

'' a flux response function with a very long tail (high ECS, high equilibration time) may give a result similar to the Schwartz exponential response function with a low ECS and low equilibration time.»

'' the information content in the temperature and OHC series is not sufficient to allow accurate estimation of ECS and equilibration time;»

[Response: But the mixing time for the atmosphere is short, about a year for exchange between the hemispheres and much shorter for mixing along latitude circles, shorter than the thermal equilibration time from rising greenhouse gases.

Overall, model experiments show a CO2 equilibration time of a few centuries [5, 6, 11, 12].

If we don't have to wait for equilibration every time, surely it can't be too onerous to plot out the sensitivity from present levels to, say, 3x?

If we don't have to wait for equilibration every time, surely it can't be too onerous to plot out the sensitivity from present levels to, say, 3x?

Not exact matches

From changes in local bond distances (OH · · O and O · · · O) with time, we elucidated the structural changes in the far - from - equilibrium regime at short times and near - equilibration at long times.

«What we realize is that in almost any quantum system, including on quantum computers, if you just let it evolve and you start to study what happens as a function of time, it's going to thermalize,» added Neill, referring to the quantum - level equilibration.

Corresponding time for surface + tropospheric equilibration: given 3 K warming (including feedbacks) per ~ 3.7 W / m2 forcing (this includes the effects of feedbacks): 10 years per heat capacity of ~ 130 m layer of ocean (~ heat capacity of 92 or 93 m of liquid water spread over the whole globe)

Thus the time scale for equilibration is proportional to the climate sensitivity * heat capacity.

IPCC: «Equilibration of surface ocean and atmosphere occurs on a time scale of roughly one year.

But a single time scale just doesn't express the multi-compartment transfer rates — a fifth to a third of the CO2 remains in the atmosphere after even a 40 - year half - life of ocean equilibration (which quite frankly agrees with my numbers — I get about a back of the envelope number of ~ 37 years half - life, depending on the saturation limits), and the rest will be around for quite a while.

Note thermo can't tell us how long but experimental evidence shows the time frames to equilibration are relatively short.
