Dr. Nehrkorn has been with Atmospheric and Environmental Research since 1985. He received his Ph.D. in Meteorology from MIT with Kerry Emmanuel as his thesis advisor. Prior to that, Dr. Nehrkorn studied and received his M.S. in Atmospheric Science from Colorado State University under William Cotton, and his B.S. in Meteorology from The University of Hamburg, Germany.
Dr. Nehrkorn’s 30 year research tenure at AER has included work on numerical weather prediction models, data assimilation systems, humidity to cloud relationships, three dimensional analysis of atmospheric quantities and studies of the angular momentum budget of the atmosphere. His prior work in hurricane modeling focused on probabilistic track and intensity forecasts. His research activities revolve around tropical cyclone simulations and prediction models, 3D and 4D variational analysis schemes, ensemble forecasting techniques and coupling of mesoscale Numerical Weather Prediction (NWP) models to Atmospheric Transport and Dispersion (ADT) models.
He is a member of the American Meteorological Society (AMS) and the American Geophysical Union (AGU) and has published and presented over 110 papers in refereed journals and technical conferences.
