Definition: Landspout: A tornado that does not arise from organized storm-scale rotation and is therefore not associated with a wall cloud (murus) or a mesocyclone.

Landspouts are typically observed below Cumulonimbus or towering Cumulus clouds (Cumulus congestus), often as no more than a dust whirl, with rotation typically originating from lines of horizontal shear. They are essentially the land-based equivalent of waterspouts.
