- Large and very low wall cloud on a rotating mesocyclone
- W991054Z
- Close-up of W991060S, showing a large and very low wall cloud, possibly enhanced by topography, under the forward flank inflow region of an HP supercell storm. It is newly formed and still a little loose in structure, but pulling together. The circular, three-dimensional rotating mesocyclone is evident in the cloud structure above it as well.
