Global Chimney in the Pacific
January 9, 2014 | National Science Foundation

“Although few people live in the Western tropical Pacific Ocean region, the remote waters there affect billions of people by shaping climate and air chemistry worldwide.

Next week, scientists will head to the region to better understand its influence on the atmosphere–including how that influence may change in coming decades if storms over the Pacific become more powerful with rising global temperatures.” Quoted from the NSF press release.

Why Does it Rain More in the Northern Hemisphere?
October 30, 2013 | University of Washington

“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.

Pacific Ocean Temperatures Influence Tornado Activity
October 19, 2013 | University of Missouri

“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.

The Largest Deep Earthquake Ever Recorded
September 22, 2013 | University of California Santa Cruz

“A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometers (378 miles), the intense pressure on the fault should inhibit the kind of rupture that took place.” Quoted from the University of California Santa Cruz press release.
