- Circular mesocyclone of a supercell
- W922507S
- Close-up of W922503Z, showing the circular mesocyclone of a supercell. It has a flared base which looks similar to a large lowering. However, the actual wall cloud is farther back, hidden in the darkness beneath this outer and larger feature which encircles the entire updraft base. The use of an ultra wide-angle lens belies the immense size of this feature.
