Cyclones typically form over warm ocean waters where the temperature is at least 26.5°C. The warm water heats the air above it, causing it to rise and create a low-pressure area. As the air rises, it cools and condenses, forming clouds and releasing heat, which further fuels the system. The Earth's rotation causes the system to spin, creating the cyclonic structure. This process can intensify, leading to the development of a full-fledged cyclone.
