Default The Sky is the limit -- contrails

We were driving down the Oregon coast on Highway 101 a couple years ago when I spotted this most unusual cloud formation. I don't think this is jet contrails but if not, I have no idea what caused this formation.

Cal, that is really great. I would be tempted to send the picture to a local meteorologist and ask. There seems to be several different types of clouds in your image.

Great picture.
My best guess is that they are altocumulus (Mid level) clouds aligning themselves with the jet stream. As they recede into the distance you are getting a perspective effect causing them to converge at the horizon above the fog.

Love the picture whatever the reason Cal.

Interesting to see the high clouds with blue skies, balanced by the water and low fog bank. Good photo.

Steve is correct - what meteorologists call "altocumulus in rolls," resulting from wind shear at the interface between two layers of air. Here is Noaa's definition:


Nice shot, too.

It really is a fascinating shot, don't think I've ever seen clouds like that.
