A major winter storm is threatening the Washington, D.C., area this week, on the heels of record-setting snowfalls and blizzard conditions in several parts of the United States last month. Are these onslaughts catching people off guard?
NCAR scientists have performed one of the most detailed simulations ever of a massive tornado outbreak. They simulated two waves of tornadic storms that occurred on April 27,2011 in Alabama, the deadliest U.S. tornado day since 1925.
Last year, a team of NCAR scientists verified that the Weather Research and Forecasting model (WRF) can be used to depict seasonal snowfall in Colorado with a high degree of accuracy. Now the team is using WRF to forecast future snowfall.
Talea Mayo, University of Texas at Austin • No two days are the same for this student of computational and applied mathematics. She's working to improve hurricane storm surge predictions by focusing on how data gets added, or "assimilated," into a forecasting model.
A team of scientists led by NCAR’s Keith Oleson has incorporated urban areas into a global climate model. The development is important because most models used for predicting future climate change do not account for the urban “heat island” effect.
It’s been a busy spring for community climate modeling at NCAR. One major release pushes the veteran CCSM forward. Another release is on the way: the Community Earth System Model, which brings a new paradigm into the mix.
NCAR scientist Natasha Flyer is using an innovative method known as radial basis function (RBF) to model simple physical processes in the geosciences. The research is poised to offer a new way of solving equations that could significantly improve models used by atmospheric and solar scientists.
By simulating 8,000 years of climate, a team led by scientists from the University of Wisconsin–Madison and NCAR has found a new explanation for the last major period of global warming, which occurred about 14,500 years ago.
In a breakthrough that will help scientists unlock mysteries of the Sun and its impacts on Earth, an international team of scientists led by NCAR has created the first-ever comprehensive computer model of sunspots.
A new technique developed at NCAR will help asteroseismologists learn about stars from their oscillations, or “starquakes.” These variations in the brightness of stars reveal information about their internal structures.
One of the challenges for global climate modelers is accurately simulating cloud cover and its changes over time. This is vital for projecting future temperatures, rainfall, and other aspects of global and regional climate change.
