Mist on the water

This morning it was wind still.
And there was mist (vapor, fog… I dunno) on the lake.

The mist was flowing from all directions to a central point. I’ve never seen that before.

Then, after about 20 minutes, it all started flowing in one direction (as per usual).

Any explanations?

Was there a Frank Zappa concert at nearby casino?

Hell, man, who knows?

Does the air get colder than the lake water at night?

Was the sun shining directly on the ground around the lake at the time the fog was converging to a point (presumably over the water)?

Did a slight breeze start up after the 20 minutes?

How big is this lake, anyway? Or is it more like a pond?

Well… in Brabant in the Netherlands it’s called a plas. Which translates to urinine or puddle.

It’s bigger than a pond. It’s a small lake.

I take for granted that there must have come a breeze to change the misty movement.

As for the rest of your questions… it looked like there was a central point at the far end of the lake which was drawing the mist in.

And you weren't high at the time?

Mists that gathered over a lake at night tend to dissipate as the day heats up, and I think the usual way this happens if there is no significant breeze is from the edge (the shoreline) in toward the center of the lake. I think. The ground heats up faster than the water or air. The effect might create the illusion that the mist or fog is moving toward the lake's center.

Water cools down slower at night so in the morning it's warmer than the land. This could cause an updraft in the middle of the lake drawing in air and the mist with it at ground level. Once the ground warmed up to the water's temperature and then beyond the wind patterns shifted to what you are used to seeing.

That's my guess.

Aha! Yes. This makes sense!


Thank you both for the input.
