Profound Impacts Of Fireworks On Visibility As Well As Air Quality
The visibility this morn was greatly reduced compared to yesterday as well as fireworks fume played a major role.
Here is thought from the Seattle PanoCan looking towards the Cascades at 9:30 AM this morn (Thursday, July 5). Very hazy alongside the foothills barely visible. The haze is from fireworks.
The solar daytime earlier at the same fourth dimension (July 4th, of course). Some clouds aloft, exactly MUCH improve visibility. You tin john fifty-fifty meet Mt. Rainier.
Now you lot don't stimulate got to stimulate got my discussion for the being of plumes of fume from fireworks.... lets stimulate got a expect at the observations taken past times the Puget Sound Clean Air Agency. Here is the sum of small-scale particles inward the air (PM2.5) on Seattle's Beacon Hill. Huge as well as sudden increment of particles during the eventide of July 4th, to values over 100 (micrograms per cubic meter). This is inward the unhealthy level.
But why was inward hazy this morn looking east? To figure this out, let's examine the particles levels at Bellevue (brown line) as well as North Bend, most the Cascade foothills (green line). Big increment during the eventide of the fourth, exactly the levels stayed relatively high!
I suspect a lot of the fume over the populated expanse most Puget Sound got pushed towards the due east this morning. In fact, the time-height cross department of current of air as well as temperature at Seattle Sand Point provided past times Puget Sound Clean Air Agency (see below) does advise this (below). The winds were easterly during the afternoon exactly switched to westerly at depression levels for several hours overnight (heights are inward meters ASL, fourth dimension inward UTC increases to the left)
And don't holler upward Seattle was the exclusively house alongside smoke. It was worse inward Tacoma as well as Marysville, abode of Boom City, had a occupation also (see below).
Last fourth dimension I was watching the Lake Union fireworks display alongside students, staff, as well as faculty on the transcend of my building, as well as the fume became increasingly extensive during the brusk show.
By eleven PM, the smoky scene was commencement to expect apocalyptic.
Several people told me they felt cold-like symptoms this morn from the left-over smoke. In whatever case, air lineament volition improve chop-chop similar a shot every bit a Pacific forepart moves through bringing an influx of clean, marine air.
Finally, at that spot may move a superior replacement for the smokey fireworks---performances of hundreds of drones alongside LED lights. Check out this video to meet what I mean.
