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.

The largest and most ambitious tornado study in history will begin next week, as dozens of scientists deploy radars and other ground-based instruments across the Great Plains to gain a better understanding of these often deadly weather events.

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 scientist Fei Chen is collaborating with colleagues at China’s Institute of Urban Meteorology to explore how growth in Beijing is changing the city’s summer rainfall patterns, focusing specifically on the relationship between urban expansion, aerosols, and summer rainfall.
