Atmospheric "filament"

From "Jos" at weerrecords, via David Sands:

"The Earth's atmosphere has a tendency to form filaments, very long thin streams of air with similar properties, for example this one from yesterday with North Amnerican wildfire smoke.

Rarely seen such a nice one. The bloody thing must be more than 10,000 km long. #TROPOMI #S5P"
