For decades, NASA researchers have helped refine our understanding of hurricanes and tropical storms. To better understand the Atlantic hurricane season, they use the Goddard Earth Observing System (GEOS-5) model run by supercomputers at NASA's Goddard Space Flight Center, in Greenbelt Maryland. In the model, scientists at NASA's Global Modeling and Assimilation Office (GMAO) simulated the conditions in the ocean and atmosphere that give rise to tropical storms and hurricanes. From these simulations, he can better isolate and understand which factors play a role in driving a busy or a slow Atlantic hurricane season. The full study is available here.
