Surface wind speeds range from blue (10 miles per hour) to purple (80 miles per hour). Surface and near-surface (850 hPa) wind speeds from the NASA Goddard Earth Observing System Model (GEOS-5) operational assimilation system (consisting of a 50-kilometer analysis coupled with a 25-kilometer model) beginning September 1, 2012 preceding a 7-kilometer global simulation with the GEOS-5 atmospheric model initialized at 09Z on October 26, 2012 reveal the massive size of Hurricane Sandy versus the other storms for this period, including the persistent Hurricane Nadine, as well as hurricanes Michael and Rafael. The 7-kilometer simulation depicts the strong onshore winds in New York and New Jersey even after landfall and the dramatic influence of the land surface slowing down Sandy s near-surface (850 hPa) winds. Sea level pressure, wind speeds, and accumulated rainfall from a GEOS-5 28-km simulation versus National Hurricane Center (NHC) observations. Sea level pressure, wind speeds, and accumulated rainfall from a GEOS-5 7-km simulation versus National Hurricane Center (NHC) observations. Accumulated rainfall from the Tropical Rainfall Measuring Mission (TRMM) satellite, a GEOS-5 7-km simulation, and a GEOS-5 28-km simulation.
