The savanna lands of the northern regions face harmattan winds for four months each year. |
In winter and spring, when they are strongest, they are known as the harmattan. |
The result is that pupils know more about the Seine than the Niger, or about the mistral than the harmattan. |
In winter the drying harmattan wind blows from the interior. |
During the harmattan, a cool, dusty wind from the Sahara grays the skies. |
In the dry season the harmattan, a hot, dry wind, blows from the northeast from December to March. |
