WRF-Fire: East Troublesome Wildfire from Granby, CO
On October 14, 2020, the East Troublesome Wildfire ignited. It burnt 193,812 acres over the course of 48 days. Between October 20-23 the wildfire rapidly intensified, exploding from 18,550 acres to 187,964 acres in size.* These visualizations show a Weather Research & Forecasting (WRF) simulation of the East Troublesome Wildfire from the perspective of Granby,…

Aquaplanet simulations—as their name suggests—are idealized representations of Earth where the planet is covered entirely by water. The absence of continents, while unrealistic, provides a clean laboratory where weather systems can develop, evolve, and dissipate as they would do over Earth’s oceans. This kind of simulation is, therefore, useful for learning about the fundamental processes…
Read moreOcean Surface Boundary Layer Turbulence Under Hurricane Irene
Simulated ocean surface boundary layer turbulence under Hurricane Irene (~9:30 UTC, August 28, 2011) entrains cold bottom water that cools the sea surface and weakens the hurricane as it makes landfall on the New Jersey continental shelf. Large-aspect-ratio coherent structures that modify the evolution of the mean sea-surface temperature are highlighted in a 2 km by 2…

Precipitation in warm clouds can be explained by coalescing water droplets. This coalescence can be accelerated by turbulent vortices within the cloud. In this visualization, we see how this turbulence drives the coalescence of large and small droplets.

Read moreModelling The Indonesian Throughflow
Rising ocean temperatures have given rise to coral bleaching events at higher rates than have been seen in observed history. Researchers at the National Center for Atmospheric Research are studying how effectively coral reef ecosystems can repopulate each other after bleaching events through a metric called Potential Connectivity. In this visualization, we observe a state…
