- Birth of a thunderstorm cloud: a sustained, organized updraft
- W021681S
- Birth of a thunderstorm cloud. Every storm begins with a sustained, organized updraft. This requires a large convective cloud or a cluster where updrafts are protected and grow with minimal interference or dry air entrainment. This step starts with one stronger updraft emerging from among a field of smaller Cumulus clouds., as here. See W021682S next.
