Photo capturing thundersnow, snowfall accompanied by lightning
03.19.25 - Scientists Simulate the Electrical Dynamics of Thundersnow at NCCS
In a first-of-a-kind study, NASA, university, and industry scientists simulated the electrical dynamics of thundersnow — lightning within snowfall — at the NASA Center for Climate Simulation (NCCS).

03.14.25 - New Grace Hopper Nodes Double the Power of NASA's Cabeus Supercomputer
As part of the NASA Advanced Supercomputing (NAS) Division’s goal to provide NASA with the computing power needed to support the agency’s missions and programs, 350 NVIDIA Grace Hopper nodes were added to the Cabeus supercomputer, providing more than 13 petaflops of computing power and more than doubling Cabeus’ total peak capability.
Visualization of GEOS-FP Mid-Atlantic snowstorm forecast
03.14.25 - GEOS-FP Excels at Predicting Presidents' Week Mid-Atlantic Snowfall
A large snowstorm struck the Mid-Atlantic just after Presidents' Day. While many NWP models had to shift their snowfall locations in the days leading up the event, GEOS-FP had the snowstorm correctly forecasted from the beginning. GEOS-FP runs daily at the NCCS.
Western boundary currents stand out in white in this visualization built with ECCO data
03.03.05 - Going With the Flow: Visualizing Ocean Currents with ECCO
NASA scientists and collaborators built the ECCO model to be the most realistic, detailed, and continuous depiction of the ocean ever developed. ECCO runs at the NAS Facility. Read the story, watch the video, and look at the many new visualizations..
Image of spiral structure composed of billions of comets in the inner solar system at its heart
02.27.25 - NASA Supercomputer Finds Billions of Comets Mimicking the Milky Way’s Shape
Spirals are a repeating theme in astronomy, with arguably the most famous example of a swirling armed structure being our home galaxy, the Milky Way. Now, using NASA's powerful Pleiades supercomputer, scientists have discovered yet another spiral structure on the edge of our solar system.
Visualization showing that prevailing winds can energize ocean weather patterns if their spin is aligned
01.31.25 - How Does the Atmosphere Affect Ocean Weather?
The NCCS helped enable University of Rochester research revealing the surprising ways atmospheric winds influence ocean eddies, shaping the ocean’s weather patterns in more complex ways than previously believed.
