70/156 Přehled fotografií
Alfalfa OK, 22 May 1981, looking NNW. A "textbook" tornado extending from the wall cloud of a classic supercell, with a "clear slot" cutting through the cloud base around the near side of the wall cloud. The slot represents part of the occlusion downdraft, an arc of sinking air believed to contribute to tornado development in many cases. The tornado did damage rated at F2.
