Wall clouds / lowerings: Stock photos of all wall clouds (mesocyclones) and cloud base lowerings associated with supercells and weaker storms. This is the inflow region (main updraft) feeding up into a severe storm cloud complex.

  • A supercell lowering tightening into a wall cloud
    • W031622S
    • +
  • A storm updraft is beginning to rotate and mature this wall cloud
    • W031130S
    • +
  • A newly-formed, tapered lowering under a storm’s base
    • W031128S
    • +
  • This looks like a lowering because of the illusion of perspective
    • W031061Z
    • +
  • A supercell mesocyclone develops a wall cloud with tail cloud
    • W030935S
    • +
  • A new cloud forms, with a lowering on its updraft base
    • W030932S
    • +
  • A large storm cloud base lowering shoved forward by outflow air
    • W030642S
    • +
  • A concave cloud base on a supercell is good evidence of rotation
