This visualization shows a Goddard Earth Observing System Model, Version 5 (GEOS-5) run of the 2005 Hurricane Season driven by Sea Surface Temperatures (SST). The simulation was seeded at the beginning of the run and then ran on its own to create the 6 months of output visualized here. What's interesting is that even though the model did not perfectly duplicate all 27 storms from that very active 2005 hurricane season, it does show 23 storms during that same period. Considering this was an anomalous year, the model did a good job of simulating the large number of storms for that season. An innovative aspect of this global model is the ability to represent realistic hurricane intensities, including 6 hurricanes in the Atlantic for 2005 reaching major strength (category 3 or higher on the Saffir-Simpson scale). This finding could help shape future climate models in predicting hurricane season intensities.
Ocean colors ranging from blue to orange depict air temperatures 2 meters (T2M) above sea level. Since SSTs are typically measured at sea level and below, the T2M model output behaves somewhat differently. Nonetheless, it is a reasonable proxy to SST. Landcover information is taken from the Next Generation Blue Marble dataset. Sea Ice is depicted as solid white and clouds are shades of white.
The large animation above is diced-up into smaller tiles that can be played on the hyperwall. Each tile is named according to a standard spreadsheet convention with a1 at the upper left and c3 at the lower right. This image illustrates this naming convention used in the diced-up frame sets below.
