Siberian smoke reaches the Pacific Northwest


Massive fires have broken out in Siberia, and with Russian personnel being dragged away for criminal activities in Ukraine, the hells are spreading fast.

The smoke was evident in the satellite image visible around noon on Sunday (look for the subtle blur over the coastal waters just off the West Coast). This is from NASA’s MODIS satellite.

The MODIS satellite was able to locate where it was seeing particles associated with smoke/dust, as illustrated by images at the same time.


Some people said they saw an orange/reddish moon due to the smoke, as shown in this image from the National Weather Service in Seattle on Sunday.



The smoky air moving off Northeast Asia was clear 5 days ago (see below)


And then moved across the Pacific by jet stream and propelled north and south by weather systems:


Fortunately, the smoke was already high and the air quality of the Northwest remained good (green circles in the map below from AIRNOW)

April is a big month for smoke or dust to move from Asia to the Northwest. The jet stream is still reasonably strong, and dust storms in the Gobi Desert or fires in Siberia could provide particles that can move quickly across the Pacific.
