The Harmattan is a season in the West African subcontinent, which occurs between the end of November and the middle of March. It is characterised by the dry[1] and dusty northeasterly trade wind, of the same name, which blows from the Sahara Desert over West Africa into the Gulf of Guinea.[2] The name is related to the word has Harmattan in the Twi language.[3] The temperature is cold[1] in most places, but can also be hot[4] in certain places, depending on local circumstances.[5] The Harmattan blows during the dry season, which occurs during the lowest-sun months. In this season the subtropical ridge of high pressure stays over the central Sahara Desert and the low-pressure Intertropical Convergence Zone (ITCZ) stays over the Gulf of Guinea. On its passage over the Sahara, the harmattan picks up fine dust and sand particles (between 0.5 and 10 microns).
