Nonlinear dynamical systems, although strictly deterministic, often exhibit chaotic behavior which appears to be random. The determination of the probabilistic properties of such systems is, in general, an open problem. Closure approximations for mom

Numerical weather prediction has provided routine forecasts of global weather for more than thirty years. During the period numerical models have evolved from the use of low resolution balance equations to high resolution fluid dynamics equations wit

The traditional Smagorinsky subgrid‐scale viscosity (CSλ)2S has been supplemented by the addition of stochastic backscatter. The random acceleration is derived from a vector potential Cb‖S δt‖3/2(λ/δt)2g. Here S is the local strain rate, λ

The theoretical skill of Monte Carlo approximations to the stochastic dynamic forecasting technique proposed by Epstein is examined by means of an extension of earlier atmospheric predictability studies that used the test-field model of two-dimension

The first iteration of the recently developed nonlinear normal mode initialization procedure for primitive equation models leads to quasi-rotational dynamical and diagnostic equations agreeing with those of quasi-geostrephic theory in a simple Boussi

Among fluid systems, surely it is the atmosphere whose behavior has always been the most discussed, predicted, feared, and enjoyed. It is thus not surprising that the changes in the atmosphere are more thoroughly measured than those of any other flui

The fluctuation-dissipation theorem of statistical mechanics, proved in this note for a system with two quadratic integrals of motion such as that of two-dimensional or geostrophic turbulence, relates, the mean response to impulsive external forcing

Climate change studies with general circulation models require the estimation of climatic means by calculation of finite-time averages. A simple stochastic model is used to estimate the standard error of such an estimation method as a function of ave

Total cross sections of 33 elements for 42-Mev neutrons have been measured using the 184-inch cyclotron as a source of neutrons and the ${\mathrm{C}}^{12}(n,2n){\mathrm{C}}^{11}$ reaction as a detector. Experimental details are described and the resu
