cyclogenesis
Cyclone formation process
Cyclogenesis is the formation or intensification of a cyclone—a low-pressure weather system with rotating winds.
Meteorologists track cyclogenesis to predict storms: Rapid cyclogenesis over the Atlantic produced hurricane-force winds.
The opposite process, a storm weakening, is cyclolysis.
