- Storm anvil cloud formation process: young and mature anvils
- W011018S
- Storm anvil cloud formation process. A young anvil begins at lower right while a mature one moves overhead from a regenerating older storm in the distance. Subsidence is creasing the underside with weak Mamma. Updrafts near the core are strong enough to force anvil material sideways as they shear forward, which can be seen by the outward curving anvil edges.
