" Partly Cloudy With a Chance of Chaos: An Introduction to Numerical Weather Prediction and its Role in Present-Day Meteorology"
presented by George Modica


Present day meteorological forecast methods rely heavily upon guidance provided by computer models of the atmosphere. These numerical weather prediction (NWP) models have a rich history that predates even the development of the first electronic computers. This talk will present some of the historical foundations of present-day NWP leading to today's suite of forecast models. I will explain the major categories of today's NWP models and their operational implementations. I will also describe how our National Weather Service is structured to utilize and distribute this information. Concluding remarks will address some of the challenges ahead.

George Modica is a Senior Staff Scientist and Program Manager at Atmospheric and Environmental Research, Inc. in Lexington Massachusetts. He earned his B.S. and M.S. degrees in meteorology from the Pennsylvania State University. From 1985 to 1997, Mr. Modica worked in the Atmospheric Science Division at the Air Force Research Laboratory, formerly  located at Hanscom AFB. He joined AER in 1998 where, in addition to numerical weather prediction, he worked on topics in satellite meteorology, weather impacts on aviation and communication systems, cloud forecasting, and renewable energy. Mr. Modica holds a certification from the American Meteorological Society. He lives in Chelmsford with his wife Lysa (also a meteorologist!) and son Matthew.
