Clouds bend and swirl into a massive Category 4 typhoon that spins toward China. Luckily the storm only exists inside the mind of a supercomputer. The artificial storm is seen in a new visualization of Earth’s atmosphere that’s based on an extremely high-resolution supercomputer simulation created by NASA’s Goddard Earth Observing System Model, Version 5 (GEOS-5). The model uses data to generate virtual scenes that mimic the natural world. Seeded with observations that include sea surface temperatures, industrial emissions and volcanic eruptions, the model simulated clouds around the globe over a two-year period from 2005 to 2007. Watch the video to see a sample of the results.
