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,…

Simulations with MUSICA (Multi-Scale Infrastructure for Chemistry Modeling)

These visualizations depict simulations created with MUSICA (Multi-Scale Infrastructure for Chemistry Modeling). The first simulation examines the Carbon Monoxide (CO) generated by a fire plume during the major fire events that occurred in the western United States in 2022. The second simulation depicts Ozone (O3) in the troposphere over a region of the western US…

Impact of the Asian Summer Monsoon on the Composition of the Upper Troposphere and Lower Stratosphere

CO gas cloud over Asia

This visualization depicts carbon monoxide (CO) concentration over Asian. The data were generated from a simulation of 2021. The visualization coincides with the upcoming (July – August 2022) Asian Summer Monsoon Chemical and Climate Impact Project (ACCLIP). The scientists will fly from Osan, South Korea, over eastern Asia and the Pacific to gather similar data…

Leveraging Variable Resolution Capabilities in the Community Earth System Model (CESM) – Greenland

The System for Integrated Modeling of the Atmosphere (SIMA) has rolled out two new variable-resolution configurations with regional refinement over the Arctic and Greenland*. This is a 3D visualization of a simulation using the Greenland grid, which refines the big ice sheet with 1/8˚ grid resolution. The visualization shows that storms traverse the refinement region…

Weather Systems in a World without Land or Seasons

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…

CCSM Spring Snow Cover

This visualization shows 4-year running means of snow cover over North America from 1853 to 2100. These visualizations were created using the Community Climate System Model (CCSM). Primary sponsors of CCSM are the National Science Foundation and the U.S. Department of Energy, Office of Science. Movies North American Snow Depth Movie file (6MB) Polar Disk…

Ocean 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…

Coalescing Droplets in Turbulence

Coalescing Droplets

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.
