- Cloud base detail under a storm with a ruffled updraft base
- W000659S
- Cloud base detail under a storm. An updraft base, viewed overhead, with many small ruffles and lowered bits catching the sunset sidelighting. Air is rising and condensing at the base but the uneven surface shows that the air is not homogeneous but full of small-scale variations in moisture content. This can happen when a small amount of moist outflow mixes unevenly into the updraft.
