RISClimate Response Using a Three-Dimensional Operator Based on the Fluctuation–Dissipation Theorem
Publisher: American Meteorological Society
Abstract: The fluctuation?dissipation theorem (FDT) states that for systems with certain properties it is possible to generate a linear operator that gives the response of the system to weak external forcing simply by using covariances ...
Climate Response of Linear and Quadratic Functionals Using the Fluctuation–Dissipation Theorem
Publisher: American Meteorological Society
Abstract: A generalization of the fluctuation?dissipation theorem (FDT) that allows generation of linear response operators that estimate the response of functionals of system state variables is tested for a system defined by an ...
Fluctuation–Dissipation Supplemented by Nonlinearity: A Climate-Dependent Subgrid-Scale Parameterization in Low-Order Climate Models
Publisher: American Meteorological Society
Abstract: limate-system models use a multitude of parameterization schemes for small-scale processes. These should respond to externally forced climate variability in an appropriate manner so as to reflect the response of the ...
Climate Dependence in Empirical Parameters of Subgrid-Scale Parameterizations using the Fluctuation–Dissipation Theorem
Publisher: American Meteorological Society
Abstract: AbstractMany subgrid-scale (SGS) parameterizations in climate models contain empirical parameters and are thus data dependent. In particular, it is not guaranteed that the SGS parameterization still helps the model to ...
