Detailed explanation-1: -The harmattan is a trade wind strengthened by a low-pressure centre over the north coast of the Gulf of Guinea and a high-pressure centre located over northwestern Africa in winter and over the adjacent Atlantic Ocean during other seasons.
Detailed explanation-2: -The Harmattan brings desert-like weather conditions: it lowers the humidity, dissipates cloud cover, prevents rainfall formation and sometimes creates big clouds of dust which can result in dust storms or sandstorms. The wind can increase fire risk and cause severe crop damage.
Detailed explanation-3: -The harmattan season differs from winter because it is characterized by cold–dry wind, heavy dust-laden particles, and wide fluctuations in day and night ambient temperatures (AT).
