Explanation – Harmattan, hot and dry wind that blows from the northeast or east in the western Sahara, is strongest in late fall and winter (late November to mid-March). It usually carries large amounts of dust, which it transports hundreds of kilometers out over the Atlantic Ocean; the dust often interferes with aircraft operations and settles on the decks of ships. The interaction between the Harmattan and the monsoon sometimes produces West African tornadoes.
