text: Cumulonimbus has, of course, already been mentioned, but as a side note it is worth adding that although the cloud type is classified as being low-level on account of its cloud base residing below 2000 m, the top of the cloud can extend right up above the high-level ‘cirrus’ clouds and onwards to the top of the troposphere.
