He developed and leads the Arctic and Antarctic Research Group in the National Weather Center, located on campus in Norman, Oklahoma. He holds a Ph.D. from the University of Washington in Atmospheric Sciences that was received in 2009. Before arriving at the University of Oklahoma in 2011, he completed a Postdoctoral Fellowship in Polar Regions Research awarded by the National Science Foundation and carried out with scientists at the National Center for Atmospheric Research in Boulder, Colorado.

Science Specialties

Our lab's research focuses on the dynamics and physical mechanisms of high latitude atmospheric processes. We study Arctic and Antarctic processes using high resolution regional and global numerical models such as NCAR's Weather Research and Forecasting (WRF) model and the Model for the Prediction Across Scales (MPAS). Since these locations are relatively data-sparse regions of the globe, we also study atmospheric predictability through ensemble data assimilation techniques using tools such as the Data Assimilation Research Testbed (DART) to better understand how to extend information provided by observations to improve numerical models.

Current Research

Prof. Cavallo's research interests lie primarily in the study of vortex dynamics, particularly when applied to high latitude proccesses on weather and climate scales.
