“On the left, bright green auroras appear to emanate from the largest glacier in Iceland as if it’s a volcano. On the right, clouds appear tinged with the green light reflecting from the auroras.” Quoted from the NASA image release.
“It rains more in the Northern Hemisphere because it’s warmer,” said corresponding author Dargan Frierson, a UW associate professor of atmospheric sciences. “The question is: What makes the Northern Hemisphere warmer? And we’ve found that it’s the ocean circulation.” Quoted from the University of Washington press release.
“Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a particular area. Now, a University of Missouri researcher has found that the temperature of the Pacific Ocean could help scientists predict the type and location of tornado activity in the U.S.” Quoted from the University of Missouri press release.
MIT researchers have recreated Mars-like conditions within a three-story-tall cloud chamber in Germany, adjusting the chamber’s temperature and relative humidity to match conditions on Mars — essentially forming Martian clouds on Earth. Quoted from the MIT press release.
A National Geographic article titled: Scientists Weigh Climate Change Role in 2012 Weather explores the possibility that human-induced climate change might have contributed to Hurricane Sandy, drought in the Midwest or melting arctic ice.
“NOAA’s 2013 Atlantic Hurricane Season Outlook indicates that an above-normal season is most likely, with the possibility that the season could be very active. The outlook calls for a 70% chance of an above-normal season, a 25% chance of a near-normal season, and only a 5% chance of a below-normal season.
Based on the current and expected conditions, combined with model forecasts, we estimate a 70% probability for each of the following ranges of activity during 2013:
– 13-20 Named Storms
– 7-11 Hurricanes
– 3-6 Major Hurricanes
“Warmer spring temperatures since 1980 are causing an estimated 20 percent loss of snow cover across the Rocky Mountains of western North America. [...] Runoff from Rocky Mountain winter snowpack accounts for 60 to 80 percent of the annual water supply for more than 70 million people living in the western U.S.
