Sentences with phrase «perturbed model climates»

Not exact matches

IIRC, the authors were perturbed by the fact that small changes in the input - value mix of the model produced large differences in the rate of climate change.

There may be reason to strongly suspect that in any sufficiently complicated dynamical system model (such as climate) with stochastic parameters (e.g., exactly when and where a lightning strike starts a major wildfire or a major submarine earthquake perturbs ocean circulation in a region or a major volcanic eruption introduces stratospheric aerosols), it is almost certain that any given run of the model will have periods of significant deviation from the mean of multiple runs.

IIRC, the authors were perturbed by the fact that small changes in the input - value mix of the model produced large differences in the rate of climate change.

Knutti et al. (2006), using a different, perturbed physics ensemble, showed that models with a strong seasonal cycle in surface temperature tended to have larger climate sensitivity.

At UCI I work with Mike and Hossein in using a cutting - edge global climate modeling framework (UPCAM) to understand the behavior and role of low - level clouds in a perturbed climate system.

Later there is this sentence: «comparisons of perturbed - physics ensembles against the observed climate find that models with ECS values in the range 3 °C to 4 °C show the smallest errors for many fields (Section 9.7.3.3).»

Any accurate climate model must succeed in a good description of the basin, both in its natural state and in states perturbed by regional and global human activities.

In perturbed physics projections, «a single model structure is used and perturbations are made to uncertain physical parameters within that structure...» [5] That is, a perturbed physics experiment shows the variation in climate projections as model parameters are varied step-wise across their physical uncertainty.

Collins, M., et al., Climate model errors, feedbacks and forcings: a comparison of perturbed physics and multi-model ensembles.

Figure 1 from Rowlands [4], below, shows «perturbed physics» projections from the HadCM3L climate model.

Here we extend the evaluation to those variables and analyse several ensembles; two multi-model ensembles (MMEs) from CMIP3 and four structurally different single model ensembles (SMEs, sometimes also referred to a perturbed physics or perturbed parameter ensembles) with different ranges of climate sensitivity.

If there is good reason to suppose that the paradigm is failing or about to fail, as there is with the current climate paradigm based on GCM models and a perturbed equilibrium model of response to changes in pCO2 or other greenhouse gases, then it becomes incumbent on corporate management to assure that plausible alternatives are investigated to the best of their judgment and ability, including financial.

In general, the histogram of climate variables only related to dynamical process (SLP, SW clear - sky radiation) tend to be U-shape in SMEs, possibly because model parameters related to dynamical processes are not generally perturbed in the SMEs.
