Meteorology

A wall of dust kicked up by storm outflow

A haboob is an intense, short-lived dust or sand storm driven by the cold outflow (gust front) ahead of a thunderstorm, which lifts loose surface material into a dense advancing wall that can be kilometres high. Sutton's 1925 Haboobs, written from observations at Khartoum, documented the phenomenon and carried the Arabic-derived name (from habb, to blow) into the meteorological literature. The referent is a specific convectively driven dust event tied to downdraft outflow, distinct from dust raised by steady synoptic winds, and it is tracked by the height and speed of its dust wall and the collapse of visibility behind it.[1]

Unit
The height and advance speed of the dust wall, and the drop in visibility
Recovery means
Not applicable
Measured by
Observed by the leading dust-wall height and propagation speed, the associated gust-front wind surge, and the reduction in horizontal visibility
