The humble
Cumulus humilis
never hurt a soul.
...Gavin Pretor-Pinney
When we were driving to Truckee last week, I took 53 photos of these clouds. I just loved the cumulonimbus clouds! They were huge and filled the sky.
For cumulonimbus formation, you need lots of warm and moist air, increasing winds and the atmosphere around the cloud to be "unstable."
Cumulonimbus clouds are thunderstorm clouds and a threat of severe weather. They were not directly over Truckee so we had a dry evening and rain came later.
Those clouds are amazing. I can see how yo would keep shooting. Awesome composed shot. Really neat how the bottom part of the image feels like a curve, brings out fantastic lines.
At first, I thought you were in a plane to get this shot, but then I read your narrative! What an amazing shot, Cathee! Well done! Fav (p.s. Thank you for the link)
