What type of dust storms are carried by a gravity wave and occur regularly in dry regions?

<p style=";text-align:left;direction:ltr">Arab Weather - The dust storm that forms as a result of a gravitational atmospheric wave and occurs regularly in dry areas is known as a haboob.</p><p style=";text-align:left;direction:ltr"> A haboob is a type of severe dust storm that typically occurs in desert and dry regions, such as parts of the Middle East, North Africa, and parts of North America. These storms form when strong winds are generated by an air collapse from a thunderstorm or atmospheric wave, causing large amounts of dust and sand to be thrown into the air.</p><p style=";text-align:left;direction:ltr"> Haboob storms are characterised by a dense wall of dust and sand that can extend for several kilometres, significantly reducing visibility and causing disruptions to transport and infrastructure.</p>
