Sentences with phrase «stochastic atmospheric»

However, ongoing debate and recent studies suggest that stochastic atmospheric white noise is the main driver of the pattern.

This means, that the stochastic atmospheric environment (unlike GCMs) does not take the Beer - Lambert law at its face value, and there are higher order principles of physics that governs the atmospheric absorption.

It is hypothesized that the low frequency components of stochastic atmospheric variability in the North and South Pacific, namely, the North Pacific Oscillation (NPO) and Pacific - South American (PSA) variability, independently drive tropical Pacific decadal variability.

In addition, internal variability in the global ocean - atmosphere system as well as stochastic atmospheric variability could lead to additional uncertainty regarding future climate variability [54,61,62].

Rather, while the ocean may be doing something to the surface energy budget in parts of the subpolar gyre in coupled models, its effect on the AMO is small compared to the stochastic atmospheric forcing.

In a recent technical comment, Zhang et al. show that ocean dynamics play a central role in the Atlantic Multidecadal Oscillation (AMO), and the previous claims that «the AMO is a thermodynamic response of the ocean mixed layer to stochastic atmospheric forcing, and ocean circulation changes have no role in causing the AMO» are not justified.

This was accomplished using a stochastic climate model based on the concept that ocean temperature variability is a slow dynamical system, a red noise signal, generated by integrating stochastic atmospheric forcing, or white noise71.

Not exact matches

Although this index is based on the limited number of years (1997 - 2010) for which daily snow cover data exists, the high correlation between the SAI and the DJF AO suggests that the wintertime AO is indeed predictable, rather than a by - product of the stochastic behavior of internal atmospheric dynamics.

• There is strong evidence that the multidecadal SAT variability in the Atlantic (and globally) is driven (at least partly) by variations in the MOC • A stochastic scenario is most plausible, in which the ocean is driven by the low - frequency portion of the atmospheric variability (NAO).

I propose the following Climatic null hypothesis that: «Natural climatic variation is quantified by the stochastic uncertainty envelope of historical and paleo data, embodying the nonlinear chaotic interaction of atmospheric, oceanic, volcanic, solar, and galactic processes, including climate persistence quantified by Hurst - Kolmogorov dynamics.»

«Natural climatic variation is quantified by the stochastic uncertainty envelope of historical and paleo data, embodying the nonlinear chaotic interaction of atmospheric, oceanic, volcanic, solar, and galactic processes, including climate persistence quantified by Hurst - Kolmogorov dynamics.»

The method combines the results of long - term atmospheric reanalyses downscaled with a stochastic statistical method and homogenized station observations to derive the meteorological forcing needed for hydrological modeling.

Thirty years later, the relevance of this study has been realized in the development of stochastic approaches to represent cumulus convection and its upscale energy transports, and in the emerging efforts to resolve these multi-scale processes in atmospheric simulations at the cloud system - resolving scale (approx. 1 km).

But it is unclear whether or not the 1976 regime shift in North Pacific climate reflects an abrupt change in the extratropical atmosphere - ocean system or simply the random superposition of different climate signals, e.g., similar regime - shifts are reproducible in simple stochastic models forced by atmospheric noise and ENSO (Newman et al., 2003).
