Saharan dust acts like a hurricane switch that turns them on and off. Read my latest in The Post and       Courier about how climate change may affect this switch.
 
The Saharan Connection:
Will hurricanes hammer the East Coast? We traveled to the Sahara Desert to find answers.

1. Sun

Deep in the Sahara Desert, the sun heats the sand, and the air above it rises. The rising air carries dust — orange dust from Mauritania and Mali, white dust from an ancient lake in Chad.
