Flat-bottomed clouds
Posted: Tue Aug 22, 2006 6:08 pm
Can you explain what makes some cumulus clouds appear as though they are sitting on top of a glass shelf? Sometimes I've noticed how they all appear to be at the same level, like God covered us with an upside-down glass bucket and plopped dollops of cotton candy over our heads -- big, poofy white fluff blobs that a flat on the bottoms. I asked this once a long time ago (not here) and got some round-about answer concerning water vapor, but it wasn't clear enough for me to understand and I've had other people ask me. I'm sure they stop and rest at some atmospheric level, but I don't get why.
Thanks!
Thanks!
