Seminar Title: Incorporation of Stochastic Effects in Climate Models
Speaker: J. Clayton Kerce, Argos Intelligence, Marietta GA
Date/Time: 2011-10-12 15:00
Location: Building 240, 1404-1405
Description:
Stochastic parameterization of large scale models is becoming an important tool for evaluating climate predictability and for enabling accurate representation of the effects of micro-scale and short time physics on climate model statistics. Implementation of numerical schemes that properly handle these stochastic effects in large scale software is highly non-trivial. A systematic process is needed to apply stochastic parameterization techniques to representative climate models in an automated or semi-automated way. The source code transformation techniques pioneered by the automatic differentiation community are being investigated to address this problem.
In this talk I will review current research on stochastic parameterization, highlight some of the difficulties, and discuss the source code transformation approach.
