A strange, persistent "blob" of very warm water off the U.S. West Coast is now linked to the recent winters that brought extreme heat and drought to the West, and record snow and cold to much of the East, according to two studies.
"In the fall of 2013 and early 2014, we started to notice a big, almost circular mass of water that just didn't cool off as much as it usually did. So by spring of 2014, it was warmer than we had ever seen it for that time of year," said Nick Bond, a University of Washington climate scientist and lead author of one of the studies.
At one point, the blob of ocean water was 2 to 7 degrees above average and about 1,000 miles across and 300 feet deep. Since then, though, "the pattern has evolved to be more like a wide strip along the coast," Bond said.
The two studies were published in the journal Geophysical Research Letters, a publication of the American Geophysical Union.
The blob may have had some influence on the severe drought in the West, Bond said. As air passes over warmer water and reaches the coast, it produces more rain and less snow in the mountains. The low snowpack results in reduced summer water supplies for California, Oregon and Washington.

World's first 'wired volcano'
For the first time, Chadwick and his colleagues were able to observe the eruption in real time, thanks to a set of instruments connected to shore by a fiber-optic cable, installed last summer by the University of Washington and paid for by the National Science Foundation.
"This is the first place in the world where we have a wired volcano on the seafloor," Chadwick said.
