Spring fling: Sun emits a mid-level flare

UPDATE: The M6.5 flare on the morning of April 11, 2013, was also associated with an Earth-directed coronal mass ejection (CME), another solar phenomenon that can send billions of tons of solar particles into space and can ...

Superfast model brain to predict flooding during heavy rain

(Phys.org) —Heavy rain has one again resulted in widespread flooding across the country. With climate change likely to cause further severe weather events in the coming years, methods of quickly predicting flooding will ...

Weather and climate predictions are worth their weight in gold

The economic costs of damaging weather events have an immense and increasing impact on the U.S. economy, and these costs could be anticipated and mitigated by improved weather and climate predictions, say a range of experts ...

Solar storm near Earth caused by fast CME

On March 17, 2013, at 1:28 a.m. EDT, the coronal mass ejection (CME) from March 15 passed by NASA's Advanced Composition Explorer (ACE) as it approached Earth. Upon interacting with the giant magnetic bubble surrounding Earth, ...

NASA transfers operational control of environmental satellite

The Suomi National Polar-orbiting Partnership (NPP) satellite, a partnership between NASA and the National Oceanic and Atmospheric Administration (NOAA), was transitioned to NOAA operational organization control Feb. 22, ...

Lake-effect snow sometimes needs mountains

University of Utah researchers ran computer simulations to show that the snow-producing "lake effect" isn't always enough to cause heavy snowfall, but that mountains or other surrounding topography sometimes are necessary ...

Earth-directed CME released by long duration solar flare

(Phys.org)—On Feb. 9, 2013 at 2:30 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME, associated with a long duration C2.4-class flare. Experimental NASA research models, based on observations ...

Smartphones, tablets help scientists improve storm forecasts

The next advance in weather forecasting may not come from a new satellite or supercomputer, but from a device in your pocket. University of Washington atmospheric scientists are using pressure sensors included in the newest ...
