haboob
A violent duststorm or sandstorm in the deserts of Arabia, North Africa, India, or North America.
Sandstorms were very prevalent during the first three months; they are called "Haboob." A fall in temperature of a few degrees in the hot months was always accompanied by these storms.
Where it comes from
[Alt: A large dust cloud over the city] Borrowed from Arabic هَبُوب (habūb, “strong wind, gale; haboob”), from the root ه ب ب (h b b) (“relating to wind blowing”).
