‘By-the-wind sailor’ jellies wash ashore in massive numbers after warmer winters

Velella velella, also called “by-the-wind sailor” jellies, that washed ashore at Moolack Beach, Oregon, in 2018.

As their name suggests, by-the-wind sailor jellyfish know how to catch a breeze. Using a stiff, translucent sail propped an inch above the surface of the ocean, these teacup-sized organisms skim along the water dangling a fringe of delicate purple tentacles just below the surface to capture zooplankton and larval fish as they travel. At the mercy of the wind, these jellies can wash ashore and strand — sometimes numbering in the trillions — on beaches around the world, including up and down the U.S.

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.

UW DawgCast trains future broadcasters

In pre-COVID times, a group of students would huddle around a computer practicing their skills to create professional-grade weather graphics like the ones seen on local news channels or practice giving weather reports while standing in front of a green screen in a mini-TV-studio classroom. They are part of The UW DawgCast, a year-long club offered in the Department of Atmospheric Sciences jointly with a broadcast meteorology course that welcomes weather-loving students of all majors to teach them how to read, synthesize, and communicate weather.

Rating tornado warnings charts a path to improve forecasts

Tornado in Colorado

The United States experiences more tornadoes than any other country, with a season that peaks in spring or summer depending on the region. Tornadoes are often deadly, especially in places where buildings can’t withstand high winds. Accurate advanced warnings can save lives. A study from the University of Washington and the National Oceanic and Atmospheric Administration describes a new way to rate and possibly improve tornado warnings.
