A33N:
Relating the Internal Variability of Climate Systems and Their Forced Responses I Posters


Submit an Abstract to this Session


Session ID#: 51753

Session Description:
There has been much interest recently in relating the internal variability of climate systems to their forced responses. Such relationships are generally explored using linear response functions, and provide powerful tools for studying the dynamics of climate systems and their responses to imposed forcings. With varying degrees of success, techniques such as Linear Inverse Modeling and the Fluctuation-Dissipation Theorem have been used to estimate the response of the jet streams to imposed mechanical and thermal forcings; the response of cumulus convection to temperature and moisture perturbations; and to estimate Earth’s climate sensitivity; among many other applications. In this session, we invite contributions that apply such techniques to systems of relevance to climate science, which develop new techniques, expand on existing ones or more broadly discuss aspects of the connection between internal variability and forced responses, including using model-derived linear response functions to understand the structure of historical variability.
