Summary

Description
English: For decades this image was commonly misidentified as the mushroom cloud of the Little Boy bomb that formed around 8:15 AM local time. However due to its greater height and the wholly different time of day, it is a pyrocumulus* cloud that occurs frequently over firestorms.
  • A Pyrocumulonimbus cloud(PyroCb) is another superior, although not widely accepted, meteorological classification.
