Fen blows - NOT amateur radio

The UK Fens are very flat with some of the best agricultural lands in the country.  Most of the topsoil is peat.

With strong winds we can experience "fen blows" when the strong winds blow this topsoil away. At the moment we are having exceptionally strong winds for August. This morning on our walk, we could see the brown clouds of dust in the sky: evidence of a "fen blow". Although I tried to take photos, the "fen blow" is hard to make out. At the moment, winds are gusting to about 50mph here.
