What role do ocean temperatures play in hurricane formation?

Ocean temperatures are a critical factor in the formation and intensity of hurricanes. Specifically, higher ocean temperatures provide the necessary warm water that fuels these storms. When water temperatures reach about 26.5 degrees Celsius (approximately 80 degrees Fahrenheit) or higher, it allows for increased evaporation, which in turn adds moisture to the atmosphere. This process enhances convection and promotes the development of thunderstorms, which are fundamental to hurricane formation.

As the warm air rises, it creates a low-pressure system at the surface. Furthermore, the energy derived from the warm ocean water contributes significantly to the storm's intensity. As hurricane winds pull heat and moisture from the ocean, the result is a more powerful storm with stronger winds and greater potential for destruction. This relationship between higher ocean temperatures and hurricane intensity is well-documented and is a crucial aspect of meteorological studies concerning tropical cyclones.

Lower ocean temperatures, on the other hand, can inhibit storm development by reducing evaporation and the amount of available energy for the storm, while the notion that ocean temperatures are irrelevant or solely determine hurricane direction does not align with established scientific understanding of these weather phenomena.
