The Bernoulli Effect

Very cool shots. I'm not a scientist so I'll take a back seat. I would have thought it was due to wind direction when the snow was falling hardest. Not a lot of obstructions to hit.
It is fun to see nature do something you haven't seen before. And to be in the very specific conditions it takes.
I had a bizarre one in December. Brown snow. I'd heard of it but haven't seen it. Hadn't appeared here in decades. It was from a freak dust storm in the desert that moved up the mountains and worked in to the snow. Conditions had to be perfect. Glad it was natural because it looked a little toxic.

I would have never thought about connecting this to Bernoulli! Now I miss my high school physics.

@HannibalAteMeOut Heh, i have lived 80+ years and never saw this before, or never paid any attention to it! It is important to continue to learn, and to incorporate the new knowledge in your data base!

@samueltyler2 live and learn!

@HannibalAteMeOut absolutely. There is some advantage to old age!

The constant air flowing by the round tree profiles creates a low pressure zone which attracts the particles to the back side. Were it to continue, eventually it would form a teardrop shape.

Hang on, i just received an email from a meteorologist at Rutgers University:
"I assume you are talking about the snow on March 14. Actually, the winds were from the WNW that day, so the snow was indeed on the windward side of the trees. This noreaster had already passed us (and was stalled out over New England) by the time the snow was falling. We did have the customary NE winds (and some rain) on the 13th as the storm approached."
It made a good story though, I am awaiting other confirmation about the change in wind.

I recall hearing about that effect but I have never seen it in person

@RebuildingME I learned about it in physics, but no one ever mentioned the effect this way. I know of its use in developing a siphon, and in the concept of flying, but, seeing it with my own eyes on the trees was startling. There was an eraly TV show, during the very early days of TV, called Mr. Wizard. Many scientists of my age got their interest in experimentation from the show.

Very well observed and asked!
