Most Hurricanes are Category 1-3 on the Saffir-Simpson scale. Few are 4 & climatology.
September is Hurricane Month.
Global sea surface temperatures T > 81 o F=27 °C for hurricane formation
North African dust storms can weaken a hurricane season.
Warm enough ocean temperatures & large enough Coriolis force (Latitudes greater than 10 degrees)
Vertical Wind Shear
High Vertical Wind Shear: Destroys hurricane formation
Low Vertical Wind Shear Enhances hurricane formation
Stages in development knots >64 knots knots Complexes of thunderstorms Names are given to Tropical storms and Hurricanes
