B. Tropical cyclone forms in large bodies of water
C. Bodies of water near the equator are wide so typhoons can form freely.
D. Bodies of water near the equator provide warmer temperature that can trigger the formation of cyclones.

Answer 1

Answer: Tropical cyclones are like engines that require warm, moist air as fuel. So the first ingredient needed for a tropical cyclone is warm ocean water. That is why tropical cyclones form only in tropical regions where the ocean is at least 80 degrees F for at least the top 50 meters (about 165 feet) below the surface.
