🔍 Key Concepts

• Coriolis force and how it affects wind rotation in tropical cyclones • Minimum conditions needed for a tropical cyclone to develop and spin up • The special characteristics of the atmosphere very close to the Equator (Intertropical Convergence Zone, ITCZ)

💭 Think About

• Which option directly relates to the ability of air to start rotating and maintain a circular storm system? • Do tropical cyclones ever form in hot, humid areas away from the Equator, and what does that suggest about choices B and C? • Is the presence or absence of weather fronts essential for tropical cyclone formation, or are they mainly a feature of mid‑latitude systems?

✅ Before You Answer

• Verify which factor controls the rotation and organization of a tropical cyclone. • Ask whether heat and humidity are limiting near the Equator or actually abundant there. • Consider whether fronts are typically involved in tropical cyclone development, or if they belong more to extra‑tropical systems.
