[Special] Prof. J. David Neelin (UCLA): "The Rain is a Pain--The Challenges of Predicting Rainfall Changes Under Global Warming"

Despite successful simulation of many large-scale climate variables, climate models exhibit very substantial differences in regional scale prediction of precipitation changes under global warming. This is currently a stumbling block in regional assessment of human and ecosystem impacts. Climate models also exhibit regions of poor simulation of precipitation in current climate and have considerable trouble capturing local rainfall changes caused by the remote impacts of El Nino, a natural climate variation. In addition to being of considerable societal importance, this challenge has many interesting fundamental science issues. Climate scientists are bringing a number of tools to bear on this problem: from field campaigns and satellite retrievals--providing improved observations of key factors affecting precipitation--to tools borrowed from statistical physics, stochastic processes and optimization theory to help incorporate these in climate models.

Professor Neelin is the 2011 Graduate Students' Distinguished Visiting Lecturer.
