Re: Explanation of Orca Map

The darker blue areas are extremely dry airmass areas.
Why do these effect hurricanes?
1. Hurricanes, ingesting dry air, weaken rapidly.
2. Dry air usually accompanies high pressure areas, which in turn cause shear conducive to the weakening of the hurricane, and also "push" the hurricane away from them.
Does this help? I'm not a met so I'm sure others can give you a better answer
