My brother shared recently:
An interesting reality of living in West Africa during the dry season is the harmattan winds. These hot, dry winds blow off the Sahara Desert carrying the finest, floury, dust hundreds of mile into the Atlantic Ocean. Considering that 60 percent of the dust in the earth's atmosphere comes from the Sahara Desert, it is not surprising that these small pieces of the Sahara even find their way to America.
Harmattans last from a few to several days at a time and are appropriately called the dry fog. I walk to school before it is light and when I look up at a light the dust forms a halo, much like heavy fog. It penetrates everything and is impossible to keep out of homes. Floors must be mopped and horizontal surfaces dusted nearly every day. It is especially harmful to electronics like computers.
