This from NOAA. This is a surface sea temperature composite image. It was compiled by a polar orbiting satellite. Red means bad. You can see how the storm generation machine works from the point that hot Saharan wind spins off the west coast of Africa. If the spin is good and the sea temperature is warm enough, the ocean feeds hot wet air into the storm system as it drags westward across the water's surface. There will be a test on this.
