"Over the past week, NASA satellites have observed an extraordinary amount of smoke injected into the atmosphere from the Australian fires and its subsequent eastward dispersal."

NASA reckons the tremendous smoke plume created from the devastating bushfires will "make at least one full circuit around the globe, returning once again to the skies over Australia," within the coming days.

As I read this report, I mused as to how this natural circumnavigation would occur on FE. Naturally, human circumnavigation is achieved simply by heading East, in relation to North on navigational equipment, as explained on the wiki.

However, what is the process that would cause natural phenomena - such as bushfire smoke - to do this?

Naturally, the skeptic in me hones in on this particular line from another report: "one expert has said it may not be visible to the naked eye." Which seems a little too convenient. But if I was to observe the arrival of this smoke plume arriving in Western Australia, how would I explain it?
