Cumulonimbus capillatus is when a storm cloud is having a bad hair day. This species of Cumulonimbus, which takes its name from the Latin for ‘having hair’, shows that the cloud has reached maturity or just passed its peak, like this one spotted here by Lise Henderson (Member 59,830) over Naramata, British Columbia, Canada. The towering cloud’s upper canopy, or incus, resembles a head of untamed hair. The ice crystals that comprise the top of the cloud appear Cirrus-like and spread this way and that in the high winds. To be able to see the full Cumulonimbus like this, you need to be some distance away from the storm system. This might mean you’ll be spared the thunder, lightning, and heavy showers such clouds can bring. ‘I kept a close eye on the cloud,’ said Lise, ‘wondering what was in store.’ But in her location, at least, the storm turned out to be benign. ‘It simply let its hair blow around wildly until eventually it dissipated.’
