    A few mornings ago in the San Francisco Bay I thought it was interesting how there was very distinct layering with fog, clear sky, and then smoke haze drifting over the area from the Mendocino fires about 80 miles north. So the next day I made a point of looking at the 24-hr time lapse video image of the bay that the Lawrence Hall of Science posts every day.

    In the time lapse you can see the upper layer of smoke haze change altitude throughout the morning hours, and then is presumably blown away (east) by the afternoon winds.

    The "pointy waves" are at the 32 second mark (just after 6am) in the attached video (couldn't figure out how to embed it). Curious if anyone has any ideas on what caused that?

    Yes, maybe that, except instead of the top of the smoke cloud being "scooped" the bottom of the cloud was scooped by winds from the onshore flow.
