This morning, as I satshivering in the haar, I noticed a light mist
drifting a foot or so above the soil of a ploughed field behind my
house.

In twenty years of weather watching I've never seen anything like it.
At first I thought it was dust being stirred up by the light SE wind,
or smoke, but it was a very local mist hugging the ground, drifting,
coming and going, on the wind, just above the bare earth.

They were taken just before midday. Temperature was 16C, the haar had
lifted a bit and the sun was just starting to shine faintly through the
low-level clouds.

What's the physics I find it hard to believe the soil is cooling the air.
