J. David Neelin, professor and vice chair of the UCLA Department of Atmospheric and Oceanic Sciences, is an atmospheric physicist and expert on climate change. Neelin specializes in "coupled processes" — the interactions among the atmosphere and oceans and land surfaces and the effect of those interactions on global climate patterns.
Neelin has researched the causes of the El Niño phenomenon — a warming of the tropical Pacific Ocean that periodically influences weather worldwide. Neelin has contributed to reports issued under the auspices of the United Nations and is a part of UCLA's Institute of the Environment and Sustainability.
