“Predicting Nor’easters: From Days Out To Centuries”
by Dr. Edmund Chang
Here on the U.S. East Coast, nor’easters cause frequent disruptions to the entire region. On top of potential losses in lives and properties, their havocs can cost billions of damages to the regional economy. Our ability to predict these storms have improved over the years, and this has provided emergency management more lead time to prepare for mitigation. In this talk, I will discuss the physical processes behind why these storms can be predicted more than a few days ahead of their occurrences, as well as explore how these storms and their impacts are projected to change under global climate change.
Dr. Edmund Chang is a Professor in the School of Marine and Atmospheric Sciences. His research focuses on investigating mid latitude storms, including how to forecast them better from a few days out to a season, how they may change under global warming, and their immense societal impacts. His research group employs a wide range of tools, ranging from analyses of gridded atmospheric analyses and state of the art climate model simulations to learn about the basic characteristics of the phenomena, examination of actual observations to validate what have been learnt from the gridded data, and dynamical studies using a suite of intermediate/mechanistic models to achieve better understanding of these observed phenomena. Dr. Chang received his B.S. in Physics from California Institute of Technology, M.A. in Astrophysical Sciences and M.A. in Atmospheric Sciences from Princeton University, and Ph.D. in Atmospheric Sciences from Princeton University.
