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.

[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.»
