What term describes a tornado that is wider than it is tall?

A tornado that is wider than it is tall is called a wedge tornado, or simply a wedge. Its broad, block-like appearance can make the funnel look more like a dark wall than a narrow cone.

“Wedge” is a visual description, not an official measure of tornado strength. A very wide tornado can be weak, while a narrow tornado can be violent. The label generally refers to the tornado’s apparent width compared with the distance from the cloud base to the ground, especially when the circulation is broad enough to obscure its classic funnel shape.

The other terms describe different appearances. A stovepipe tornado has a nearly cylindrical profile, a cone tornado tapers toward the ground, and a rope tornado is thin and often curved or contorted. These categories are informal and can change as a tornado evolves.

The 2013 El Reno tornado in Oklahoma showed why appearance can be misleading: it became extraordinarily wide and multiple-vortex, yet its official damage-based rating was EF3. Width alone does not determine wind speed, damage, or the tornado’s rating.
