This visualization was created on the Yellowstone system at the NCAR-Wyoming Supercomputing Center using a high-resolution version of the Whole Atmosphere Community Climate Model (WACCM). It shows meridional (north-south) winds at two heights.
Part 1 shows winds at Earth’s surface, where gravity waves usually have only regional impacts. Part 2 shows winds at an elevation of 100 km (about 60 miles), where their influence can become dominant. The video simulations cover a three-day period when a hypothetical tropical cyclone was present off the east coast of Australia.
