Sense Sonnet - Chiller

Pyrocumulonimbus

Pyrocumulonimbus cloud
Can form above a fire vortex,
Billowing like a ghostly shroud,
And with the fire's updraft connects,
Causing winds to intensify,
Causing a fire tornado rare,
Spinning violently through the sky,
A double demon to all there.
A twirling inferno so intense,
Just one documented so far,
Two thousand three, Australia - hence
A phenomenon quite bizarre.

Now with increasing climate change,
Fire tornadoes won't be so strange.
