NASA's Discover supercomputer is capable of simulating the world's weather at extremely fine resolutions. This high-res global atmospheric model, showing winds at a 6 mile (10 km) resolution, will help scientists better understand Earth's complex and tumultuous climate system.
Looking at the image above, surface winds (0 to 40 meters/second) are shown in white (including Atlantic and Pacific cyclones). Upper-level winds (250 hectopascals) are colored by speed (0 to 175 meters/second), with red indicating faster.

The supercomputer has to take a wide variety of variables into account, including biomass burning, volcanoes, and human-made sources.
