Jerry Mahlman (February 21, 1940 – November 28, 2012) was an American meteorologist and climatologist.
Mahlman was born on born February 21, 1940 in Crawford, Nebraska, and received his undergraduate degree from Chadron State College in 1962 and his Ph.D. from Colorado State University in 1967. From 1970 until 2000 he worked at the Geophysical Fluid Dynamics Laboratory of the National Oceanic and Atmospheric Administration at Princeton, serving as director from 1984-2000. He was most recently a Senior Research Associate at the National Center for Atmospheric Research. Mahlman died on November 28, 2012, in Buffalo Grove, Illinois, at the age of 72.
Mahlman was a pioneer in the use of computational models of the atmosphere to examine the interactions between atmospheric chemistry and physics. His early work focussed on understanding the distribution of fallout from atmospheric nuclear bomb tests. He then became interested in the physics of transport in the stratosphere, in which mixing is relatively weak and parcels of air can be tracked for long periods of time. At the Geophysical Fluid Dynamics Laboratory Mahlman collaborated with Syukoro Manabe to develop dynamical models of the stratospheric circulation that demonstrated the importance of meanders in the polar jet stream for producing exchange between the polar and subtropical stratosphere. He then worked to extend these models to include the chemistry of nitrous oxide and ozone. While Mahlman was skeptical of early work that suggested that chlorofluorocarbons were responsible for depleting the ozone layer, measurements of high levels of free chlorine in the ozone hole caused him to change his mind in late 1987, and he later was one of the first to sound the alarm about ozone depletion over the Arctic.
As director of the Geophysical Fluid Dynamics Laboratory, he became involved in interpreting the results of computer models of global warming for the public and policymakers. On global warming, he said in 2004:[1]
