Special Session 4: Effective Stochastic and Statistical Modeling of Multiscale Systems

چکیده
The response of climate dynamics on the planetary scale to changes of various global physical parameters is an area which is being extensively studied in the contemporary atmosphere/ocean science. Recently, we developed and tested new computational algorithms for predicting the mean linear response of a chaotic dynamical system to small changes in external forcing via the fluctuation-dissipation theorem (FDT). The new methods yield greater accuracy than classical FDT methods for the linear response of a chaotic dynamical system. Here we present new results of the linear fluctuation-dissipation climate response for a more realistic model of the barotropic atmosphere on the sphere over the Earth topography. We demonstrate that the apparent lack of structural stability does not seem to pose a significant problem in practice. −→∞ ∞←−

Special Session 44: Applications of Chaotic and Stochastic Multiscale Dynamics
Multiscale, chaotic and stochastically parameterized processes are common in many areas of contemporary science, such as molecular dynamics, genetics, neuroscience, nonlinear optics, and geosciences, among others. Key topics on applications of chaotic and stochastic dynamics for complex multiscale systems will be brought together in this interdisciplinary session, ranging from fluid dynamics to...
متن کاملMarkov Chain and Time-delay Reduced Modeling of Nonlinear Systems
Multiscale modeling problems have become an active research area in recent years. There are many systems involving a large set of variables and these variables mostly behave in largely different time scales. It is necessary to derive proper effective models when one needs to obtain dynamical models that reproduce statistical properties of essential variables without wasting the computational ti...
متن کاملDynamics of Macro–Nano Mechanical Systems; Fixed Interfacial Multiscale Method
The continuum based approaches don’t provide the correct physics in atomic scales. On the other hand, the molecular based approaches are limited by the length and simulated process time. As an attractive alternative, this paper proposes the Fixed Interfacial Multiscale Method (FIMM) for computationally and mathematically efficient modeling of solid structures. The approach is applicable to mult...
متن کاملMarkov Chain Stochastic Parametrizations of Essential Variables
We analyze the performance of the novel Markov chain stochastic modeling technique for derivation of effective equations for a set of essential variables. This technique is an empirical approach where the right-hand side of the essential variables is modeled by a Markov chain. We demonstrate that the Markov chain modeling approach performs well in a prototype model without scale separation betw...
متن کاملStrong Convergence Rate for Two-Time-Scale Jump-Diffusion Stochastic Differential Systems
We study a two-time-scale system of jump-diffusion stochastic differential equations. The main goal is to study the convergence rate of the slow components to the effective dynamics. The convergence established here is in the strong sense, i.e., uniformly in time. For the ergodicity assumptions, we use the existence of a Lyapunov function to control the return times. This assumption is weaker t...
