Strong wind shear inhibits hurricane development primarily because it disrupts the organization of the storm system. Hurricanes thrive in environments where there is little to no wind shear, which allows them to form a well-defined structure and maintain their strength. When strong wind shear is present, it can tilt or stretch the storm, preventing it from developing vertically and weakening the system. In essence, the instability created by varying wind speeds and directions at different altitudes can tear apart the thunderstorms that are crucial for hurricane formation and intensification.

In contrast, warm sea surface temperatures promote hurricane development by providing the necessary heat and moisture, while high humidity levels contribute to a favorable environment for storm growth. Initial disturbances are also essential as they serve as the starting point for tropical cyclone formation.
