An experimental modeling study by a team of scientists that includes NCAR’s Hanli Liu (High Altitude Observatory) points to the propagation of waves upward from the lower atmosphere as a driver for variability in the ionosphere. The research is an important step toward better understanding space weather.

NCAR researchers are studying whether the eruption of Indonesia’s Mt. Toba supervolcano about 70,000–75,000 years ago may have cooled Earth enough to initiate an ice age and potentially alter the course of human evolution.

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.

Using a highly efficient modeling technique, Pablo Ortiz (University of Granada) and Piotr Smolarkiewicz (ESSL/MMM) have simulated the role of winds in forming sand dunes and sandholes.

NCAR researchers are looking at how new generations of super-fast Graphical Processing Units (GPUs) and multicore chips, such as the Cell Broadband Engine, can be used in atmospheric models.

The 2008 Super Tuesday tornado outbreak swept through several southern states and the lower Ohio Valley, killing 57 people. NCAR scientist Julie Demuth helped the National Weather Service assess the societal impacts of the deadly storms.

NCAR scientists are exploring the use of a novel statistical technique to help steer intercontinental flights away from thunderstorms.

NCAR scientists are working on a bigger, bolder version of WACCM (the Whole Atmosphere Community Climate Model), called WACCM-eXtension, or WACCM-X for short. The enhanced version extends the model to an altitude of about 310 miles.

A team of researchers that includes NCAR’s Synte Peacock and Frank Bryan has carried out the first-ever century-long global ocean simulations with high enough resolution to capture mesoscale eddies.
