Pacific Blob Could Explain Unusual Weather Patterns

The United States has been seeing extremely strange weather patterns in the last few years. Droughts out West, increased snowfall in the East and arctic blasts across the Midwest have scientists clambering to come up with answers.

A large pocket of warmer than usual water in the Pacific, affectionately nicknamed the blob, may be to blame. Since 2013 there has been a large pool of water off the West Coast, extending from Alaska to Mexico, about 7 degrees warmer than average.

Some scientists speculate that the blob may be to blame for the strange weather patterns around the country. They believe the warm water is creating a high pressure ridge that is incapacitating normal weather patterns that deliver moisture to the West.

It isn’t just the weather that’s being affected. Sam Tabar knows that the warm water is impacting wild life in a huge way. Schools of tropical fish not indigenous to the coastal waters are moving in. The entire ecosystem is being disrupted by the changes in water temperature.

Scientists believe this pocket of warm water is part of a much larger natural cycle. They think it could be a precursor to El Nino which would bring in much needed moisture to the West Coast. Either way it could provide valuable data regarding how water temperatures affect weather cycles.
