How to avoid that stagnant air, which is here 'til Tuesday

Chris Blakeley

In some places, such as eastern Washington farms, they actually use giant fans to disrupt the inversion that causes stagnant air (which is what we've been experiencing for a week, and can leave frost on fruit trees).

But, KPLU weather expert and UW professor Cliff Mass says those fans won't work in western Washington, because the natural forces creating the inversion are too strong. Instead, he suggests taking a hike.

"If you take a short hike ... if you start at a few hundred feet up, it will be cold. It will be foggy, even frosty. But after an hour of hiking and you get up to say 2,000 feet, you will be in bright sunshine," says Mass.

The pattern will stick around at least until Tuesday, possibly longer--bringing us more foggy mornings, burn bans, and sunny afternoons.


The weekly KPLU feature "Weather with Cliff Mass" airs every Friday at 9 a.m. immediately following BirdNote, and repeats twice on Friday afternoons during All Things Considered. The feature is hosted by KPLU’s Science and Health reporter Keith Seinfeld. Cliff Mass is a University of Washington Professor of Atmospheric Sciences, a renowned Seattle weather prognosticator, and a popular weather blogger. You can also subscribe to a podcast of “Weather with Cliff Mass”shows.
