Sentences with phrase «boundary conditions»
"Boundary conditions" refers to the limitations or rules that are set at the edges or limits of a system or situation. These conditions define the framework within which something can occur and often influence the behavior or outcomes within that system. Full definition
Isn't it possible to run these regional climate models with a range of boundary conditions?

It can't come from other variables expect as boundary conditions since the future behavior of those other variables would not be known.
The long - term predictability of such systems is difficult if boundary conditions change or can not be precisely determined in the first place — just consider the weather forecast!
Those who have the power of making decisions (determining boundary conditions) in situations like this are powerful indeed.
The climate of a model can be easily defined in terms of the limit of the statistics of the model output as the integration time tends to infinity, under prescribed boundary conditions.
Here, the same model run is repeated several times with different starting conditions but with the same boundary conditions, such as a prescribed change in the chemical composition of the atmosphere.
It also works within another set of limits that I call boundary conditions.
The current processes used for testing and installation are unable to take all the local boundary conditions into account.
For those thinking this is some kind of climate madness, it's simply physics basics — draw up a problem with simple boundary conditions and find the answer.
A projection needs to have proper boundary conditions to be valid.
The emphasis will be on comparative studies of different technology stages under comparable boundary conditions.
In other words, this equation does not contain the necessary boundary condition parameters for the finite atmosphere problem.
An initial analysis of the requested display active area and the pixel density (as well as a few other boundary conditions) informs the decision about the appropriate display platform.
An ensemble of four simulations was forced with lateral boundary conditions from ECMWF global analyses for the period 8 - 22 August 1988.
Jenkins, A., H.H. Hellmer, and D.M. Holland, The role of meltwater advection in the formulation of conservative boundary conditions at an ice - ocean interface, Journal of Physical Oceanography, 31 (1), 285 - 296, 2001.
On the other hand, changes in surface boundary conditions such as sea surface temperature (SST) anomalies in the tropics (Hoerling et al. 2001, 2004; Bracco et al. 2004), winds in the stratosphere (Scaife et al. 2014; Kidston et al. 2015), and radiative changes associated with increasing GHG concentrations (Selten et al. 2004; Deser et al. 2012) may also influence the NAO.
There is a fundamental limitation to RCMs, as they are constrained by the coarse resolution boundary conditions provided by the GCMs (which tend to favour a more El Nino like state on average).
Forest (2006) states: «It is not possible to estimate the true climate system variability on century time - scales from observations and therefore, climate models are run with fixed boundary conditions for thousands of years to obtain estimates of the climate variability.»
Both RCMs use lateral boundary conditions derived from the ERA - Interim reanalysis and share the same dynamical core but use different nesting strategies, land - surface and physics schemes.
We conclude that ENSO was sensitive to changes in climate boundary conditions during the Holocene, including, but not limited to insolation.
It is in the nature of technological reason to maximize results and minimize costs.4 The decision - makers who are in charge of a given organization or task may specify boundary conditions which forbid certain means.
Boundary conditions include (1) a definition of the system or organization that is to be taken into account, (2) the time limits that are to be observed, and (3) the goals to be reached and the means allowable to reach them.
As the higher level imposes boundary conditions on the lower processes, the latter may continue blindly and independently of the comprehensive net flung by the former.
However, bottom boundary conditions in soil components of GCMs, particularly those used by the Intergovernmental Panel on Climate Change, only extend 10 meters (33 feet) below ground, perhaps leading to underestimations of continental heat absorption.
