What causes the distinctive swirling shape of a hurricane?

The distinctive swirling shape of a hurricane is primarily caused by the Coriolis effect, which results from the Earth's rotation. As warm, moist air rises from the ocean surface, it creates low pressure, drawing in surrounding air. The rotation of the Earth causes this inflowing air to spiral, creating the characteristic rotation of the hurricane. Additionally, the release of latent heat during condensation further strengthens the storm and enhances its swirling motion.
