Sentences with phrase «flux adjustments»

This also gives us more confidence in the results from the models still using flux adjustment.

It does say that the results for about half of the models involved such flux adjustments.

Actually the models do not do all that well even for zonal temperatures until exogenous fudge factors, called flux adjustments are included.

As noted in Chapter 8, Section 8.4.2, at the time of the SAR most coupled models had difficulty in reproducing a stable climate with current atmospheric concentrations of greenhouse gases, and THEREFORE NON-PHYSICAL «FLUX ADJUSTMENT TERMS» WERE ADDED.

The newer model integrations without flux adjustment give us indications of how far we have come in removing biases in the model components.

... many of our respondents expressed a preference for keeping discussion of the issue of flux adjustments within the climate modeling community, apparently fearing that climate contrarians would exploit the issue in the public domain.

The Millennium / Famous experiment uses a radically new way to run perturbed atmosphere - ocean coupled models without dynamic flux adjustments.

Most AOGCMs no longer use flux adjustments, which were previously required to maintain a stable climate.

The uncertainty associated with the use of flux adjustments has therefore decreased, although biases and long - term trends remain in AOGCM control simulations.

I.e. is there no model (coupled, without flux adjustments!)

Models are categorised based on whether or not any flux adjustments were applied.

I think I am correct in saying that of the 14 models currently being analysed by for AR4, only one uses flux adjustments.

Some modelling groups therefore used flux adjustments (i.e GFDL) to «fix» this, while others did not (i.e. GISS).

In the past few years significant progress has been achieved, but difficulties posed by the problem of flux adjustment, while reduced, remain problematic and continued investigations are needed to reach the objective of avoiding dependence on flux adjustment.

Models are categorised based on whether or not any flux adjustments were applied.

The results from CMIP confirm what was noted in the SAR in that the basic patterns of climate system response to external forcing are relatively robust in models with and without flux adjustment (Gregory and Mitchell, 1997; Fanning and Weaver, 1997; Meehl et al., 2000a).

In contrast to the two global coupled climate models in the 1990 Assessment, the Coupled Model Intercomparison Project (CMIP)(Meehl et al., 2000a) includes output from about twenty AOGCMs worldwide, with roughly half of them using flux adjustment.

For instance, Shackley et al., 1999 surveyed climate modellers about one type of fudge factor, called a «flux adjustment», which was used by many of the climate models in the 1990s.

However elsewhere the Report reveals that some results may include what is called a flux adjustment; i.e., if a model's results were wildly unrealistic a flux adjustment would be added or subtracted in the computation to give realistic results.

The Report tells that there may have been flux adjustments in the results but does not tell precisely where and how much these flux adjustments were.

The simulation of SST, sea ice extents and ocean heat transports in a version of the Hadley Centre coupled model without flux adjustments.

Some recent coupled models have achieved a stable climate without the use of flux adjustments and an important question to ask is what is the effect of flux adjustment on changes in variability.
