Climate change is expected to lessen total U.S. snowfall, but it's unlikely to rein in the most powerful nor'easters that pummel the East Coast.

A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to the explosive release of energy in a brilliant flash.

Cover crops grown in fields during winter may be warming temperatures in the northern United States and southern Canada, according to a new study by scientists at the National Center for Atmospheric Research. The crops, a land management strategy farmers use between growing seasons, create a darker surface than a snow-covered field, absorbing more heat from the Sun and producing a local warming effect.

New research by NASA and NCAR has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover.

Everette Joseph was named director of the National Center for Atmospheric Research today, following a rigorous international search. He joins NCAR from the University at Albany, State University of New York, where he is director of the Atmospheric Sciences Research Center.
