- Cloud types, TCu: a bank of Cumulus Castellanus clouds

- Cloud types, TCu: a bank of castellated Cumulus Congestus clouds with several towers that are distorted by changing winds with height (vertical wind shear). These clouds appear tall but both their tops and bases are very low in this cool, moist but marginally unstable air mass. As a cloud type, these could be considered Cumulus Castellanus clouds.
