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…

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…

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.

Water Vapor Content of the Current and Future Climate of North America

This visualization shows column integrated water vapor content over North America for the period April to June 2011, during which time one of the most destructive and deadliest tornado outbreaks to impact the United States occurred (April 25-28). Side-by-side comparison of the simulations show greater water vapor content in the simulated future climate, which can…

Visual Comparator

Visual Comparator

Visualizations enable us to detect patterns and trends in complex data sets, that might not be obvious by looking at the raw data alone. The visual exploration process often requires comparisons between multiple visualizations, either from the same dataset (E.g. different variables) or a different one, to identify relationships and compare patterns. The existing tools…

Present and Future Climate in a Global Model

This visualization shows a CESM1 model comparison between a present day (1990) and a future (2090) simulation using a business-as-usual or high emissions scenario, called RCP8.5.  Clouds represent six-hourly time steps of total water vapor for one year. Technically speaking, this is the CESM1 model variable, TMQ, defined as the total precipitable water (vertically integrated)…
