tropical storm formation

  • Warm ocean water: The sea temperature must be at least 27°C to provide enough heat and moisture.

  • Location: Forms between 5° and 30° north or south of the equator (not too close to the equator because the Coriolis effect is too weak).

  • Evaporation: Warm water evaporates, creating warm, moist air above the ocean surface.

  • Rising air: The warm, moist air rises, cools, and condenses to form clouds and thunderstorms.

  • Release of latent heat: Condensation releases heat, warming the air further and causing it to rise faster.

  • Low pressure: Rising air creates a low-pressure area near the surface, drawing in more air.

  • Coriolis effect: Causes the incoming air to rotate around the low-pressure center, forming a spinning storm.

  • Storm grows: The system strengthens as more warm air is drawn in and rises, creating a large rotating storm.

  • Eye formation: At the center, an area of calm and low pressure called the eye forms. Around it is the eyewall with the strongest winds and rain.

  • Movement: The storm moves with prevailing winds, gaining or losing strength depending on conditions (weakens over land or cooler water).
