You said not many days of fog there and no refineries there. You have those and you have lots of fossil fueled cars on the streets. You even have inversions there: Super-Inversion Over Western Washington I was going to call it Inverzilla, but perhaps that is getting old.... But the truth is that today we have one of the strongest inversions I have ever seen here in Seattle. Take a look at the temperatures above Seattle this morning. The inversion (temperature increasing with height) is incredible. 13C increase between the surface and 500 m (1640 ft). That is 23F increase in 1640 ft!! Can you imagine taking a hike up one of our foothill peaks? It would be amazing. Cold at the bottom and sweating at the top! The inversion is so strong because temperatures have warmed up aloft, a very strong offshore pressure gradient developed (producing strong subsidence/compression warming on the western slopes), and cool/foggy air is trapped at low levels. The Space Needle Cam this morning showed the shallow cold/foggy layer very well. I love the Space Needle Cam and today there was a spectacular optical effect visible...what is known as a glory surrounding the shadow of the top of the Space Needle. You see the rainbow-like circular ring of colors? Sort of like a rainbow halo. That's it. Glory's are found opposite the sun and result from a combination of reflection, refraction and diffraction of sunlight by a field of cloud droplets of similar size. One sees this effect all the time from airplanes. But not the Space Needle. ......... cliffmass.blogspot.com Seattle is well known for its cloudy, foggy, rainy weather especially in the winter. The city has about 150 clear sunny days a year ... you can quibble about that number .. it might be 160 or something. There's even a website that records whether "the mountain is out today?" iow can you see Rainier from the top of the space needle or not? Is the Mountain Out?? @IsMtRainierOut Mar 19 Yes! For the first time in a month! Is the Mountain Out?? @IsMtRainierOut Mar 15 No
