Analysis of Wind Devils

Wind Devils,
Some people know what I'm talking about.
You see them blowing powdery snow in winter,
Making you snow-blind.
You see them carrying sand from place to place,
Creating dunes in the dessert.
You see them mixing with the lunar pull,
Stirring up waves on the sea.
You see them coming at right angles in full force,
Tearing up the land.
You on the shore see them raising up the sea in a mighty monsoon, ravaging the coastline.
But I have seen them playing amongst the leaves in the autumn,
Creating miniature dervishes in doorways.
