Sentences with phrase «noise stochastic process»

Whereas the corresponding precipitation variability can be described as a white noise stochastic process, power spectra of vertically integrated soil water exhibit significant redness on timescales of years to decades, since the predictability of soil water storage arises mostly from the integration of precipitation variability.

Not exact matches

[Response: Red noise is produced by a kind of stochastic process that has more variability at longer time scales than at shorter time scales.
The question about uncertainty is a question about information about processes, whether understood, random variations (known as «noise» or stochastic processes), or systematic model shortcomings (biases).
As Richard Alley has shown in a couple of papers, the ice core data of DO events are entirely consistent with stochastic resonance — which is not chaos but arises from a simple threshold process («flicking of a switch») in the presence of noise.
In fact, it's my experience modeling stochastic processes and noise (which are inherently chaotic systems that can not be directly modeled except as probability functions) that informs this next statement: climate models can, and do, model cloud formation.
The current approach that is generally pursued assumes essentially that past climate variability is indistinguishable from a stochastic red - noise process (Hasselmann, 1976), whose only regularities are those of periodic external forcing (Mitchell, 1976).
Time series from a wide class of stochastic processes may be considered to be the output of a linear filter applied to white noise, but the terminology also applies to processes that are not the result of any filter.
The current approach that is generally pursued assumes essentially that past climate variability is indistinguishable from a stochastic red - noise process... Given such a null hypothesis, the official consensus of IPCC (1995) tilts towards a global warming effect of recent trace - gas emissions, which exceeds the cooling effect of anthropogenic aerosol emissions.»
