ABSTRACT:

Conceptual models are often used to model the Earth's climate since
they are sufficiently simple as to allow an analysis of their
fundamental structures; thereby investigating the core processes underlying
the observed behavior. However, because of their high degree
of simplification, they usually can only qualitatively match
empirical records. Frequently, disparate models have comparable
correlations with any given observation even when based on substantially
different physics. Simple comparisons of model results to observations have
proven insufficient to distinguish between such models. Furthermore, the
models  can display large sensitivity to the choice of model parameters and
forcing functions.

Using the Pleistocene glacial cycles as a test case, we will show how
modern time series analysis techniques, such as Empirical Mode
Decomposition, can be used to extract and compare subtler features of the
observational records and of the model outputs, thereby improving model
formulation, parameterization and validation.

Bio:

Dr. Charles D. Camp (Dave) is an associate professor of mathematics at Cal
Poly in San Luis Obispo, CA, USA. He received a Ph.D. in Applied and
Computational Mathematics from Caltech in 2004 and a B.A. in Mathematics
from the University of California - San Diego in 1989.  In between, he
worked as an analyst and researcher for Areté Associates studying physical
oceanographic systems. Dave is a founding member of the Mathematics and
Climate Research Network (MCRN) - a virtual research center funded by NSF
for the development of the mathematics of climate.
