We had a cool front come through today and the leading edge formed these billow cloud rows. The wind, perpendicular to the rows, travels in a wave going up and down through warmer air below and cooler air above. Water vapor more readily condenses in cooler air at the wave peaks, forming the clouds. I didn’t have time to get to a more scenic location 😦

I love interesting cloud formations! They always add drama to a photo.

A nice capture, Frank! Maybe you should offer to sell the shot to the management of the building in the foreground for promotion & advertising!

Ha, that’s my former and sometimes current employer Kriki. I don’t think I could squeeze anything out of them for a shot of their backside. 🙂

Hey, I’ve seen that place before! The sky and the clouds are beautiful though.
