Why scientists are predicting another cold, wet winter in the Pacific Northwest

La Niña in the Pacific Northwest

After a brutally hot, dry summer, chilly winds and soaking rain have finally returned to mark the start of autumn in the Pacific Northwest. According to Washington State Climatologist Nick Bond and Assistant State Climatologist Karin Bumbaco, both researchers in the Cooperative Institute for Climate, Ocean and Ecosystem Studies, chances are we’re due for a lot more cold, wet weather this winter.

VIDEO: What is ocean acidification?

Sophie Chu

We hear the phrase “ocean acidification” often, frequently connected to conversations around climate change, but what exactly is ocean acidification? The Cooperative Institute for Climate, Ocean and Ecosystem Studies research scientist Sophie Chu walks us through the causes, effects and implications of ocean acidification. Q: What do you study? A: My research focuses mainly on evaluating existing ocean carbon sensor technology and developing new technologies to measure the carbon cycle and ocean acidification.

Dryer, warmer night air is making some Western wildfires more active at night

Firefighters have reported that Western wildfires are starting earlier in the morning and dying down later at night, hampering their ability to recover and regroup before the next day’s flareup. A study by University of Washington and U.S. Forest Service scientists shows why: The drying power of nighttime air over much of the Western U.S. has increased dramatically in the past 40 years.

Remotely-piloted sailboats monitor ‘cold pools’ in tropical environments

Conditions in the tropical ocean affect weather patterns worldwide. The most well-known examples are El Niño or La Niña events, but scientists believe other key elements of the tropical climate remain undiscovered. In a study recently published in Geophysical Research Letters, scientists from the University of Washington and NOAA’s Pacific Marine Environmental Laboratory use remotely-piloted sailboats to gather data on cold air pools, or pockets of cooler air that form below tropical storm clouds.

How five global regions could achieve a successful, equitable ‘Blue Economy’

The future of an equitable and sustainable global ocean, or “Blue Economy,” depends on more than natural or technological resources. A new study finds that socioeconomic and governance conditions such as national stability, corruption and human rights greatly affect different regions’ ability to achieve a Blue Economy — one that is socially equitable, environmentally sustainable and economically viable. A paper published March 17 in Nature by the University of Washington-based Nippon Foundation Ocean Nexus Center suggests how different parts of the world might begin to achieve these goals.
