TITLE:
Challenges in Understanding the Atmosphere

ABSTRACT:

Atmospheric science provides a fertile area for statistics due to the range of temporal and spatial scales of geophysical processes.  This overview targets three different areas where statistics is important: developing
parameterizations and analyzing output of general (global) circulation models, combining data and model output for weather forecasts and using model output to predict clear air turbulence.  The emphasis will be on the use of numerical, deterministic models in the geophysical sciences and how they vary depending on
the spatio-temporal scales that are of interest. It is important for the statistical community to realize that such models represent the confluence of many individual scientists efforts, running to many millions of lines of code and requiring high performance computing to run at useful levels of resolution. The richness of these models provide many opportunities for the development of new statistical methods and also new theory.  Some specific areas are nonlinear times series, high dimensional models, and flexible discriminant analysis.
