Air Pressure and the Transportation of Particles

This NOAA HMS image above shows that smoke from the Swan Lake Fire in Alaska is traveling in an interesting flow(Figure 1). The NASA Worldview image shows that the smoke is following the low-pressure curves as shown by the gaps in the clouds(Figure 2).

This pattern is also shown by the NRL/Monterey Aerosol image above(Figure 3).  The concentrated dust surface concentration is caused by sand from the Sahara shown in the NASA Worldview image below, crossing over the Atlantic to the Tropical Atlantic Region(Figure 4). However, the sand is shown moving in a curved pattern due to Hurrican Dorian (circled in red below).


In the NRL/Monterey Aerosol image above there is a cluster of smoke over the Pacific Ocean(Figure 5). This is supported by the NASA Worldview image below where the smoke matches the area where there are no clouds located(Figure 6).
