Tracking a Superstorm

June 6, 2013

Hurricane Sandy’s near-surface winds are visible in this NASA GEOS-5 global atmosphere model computer simulation that runs from Oct. 26 to Oct. 31, 2012.

The model works by dividing Earth’s atmosphere into a virtual grid of stacked boxes. A supercomputer then solves mathematical equations inside each box to create a weather forecast predicting Sandy’s structure, path and other traits. The NASA model not only produced an accurate track of Sandy, but also captured fine-scale details of the storm’s changing intensity and winds.
