“Excuse me, Mr. Weatherman!” she said in a letter to the editor. “Who gave you the right to use the word ‘haboob’ in describing our recent dust storm? While you may think there are similarities, don’t forget that in these parts our dust is mixed with the whoop of the Indian’s dance, the progression of the cattle herd and warning of the rattlesnake as it lifts its head to strike.”

Dust storms are a regular summer phenomenon in Arizona, and the news media typically label them as nothing more than that. But the National Weather Service, in describing this month’s particularly thick storm, used the term haboob, which was widely picked up by the news media.

“Meteorologists in the Southwest have used the term for decades,” said Randy Cerveny, a climatologist at Arizona State University. “The media usually avoid it because they don’t think anyone will understand it.”

Not everyone was put out by the use of the term. David Wilson of Goodyear, Ariz., said those who wanted to avoid Arabic terms should steer clear of algebra, zero, pajamas and khaki, as well. “Let’s not become so ‘xenophobic’ that we forget to remember that we are citizens of the world, nor fail to recognize the contributions of all cultures to the richness of our language,” he wrote.

Although use of the term often brings smirks, Mr. Cerveny said the walls of dust could have serious consequences, toppling power lines and causing huge traffic accidents. Although ultradry conditions in the desert are considered one cause for the intensity of this year’s storms, Mr. Cerveny pointed to another possible factor: the housing bust that left developments half-finished and unmaintained, creating more desert dust to be stirred up.
