What you'll learn
How weather hazards form and affect people.
Tropical cyclones
- Form over oceans warmer than ~27 °C; the calm centre is the eye.
- Storm surges raise sea levels and cause coastal flooding.
Other hazards
- Droughts: prolonged below-average rainfall.
Effects and responses
- Primary effects and preparation (early warning, evacuation).
- Poorer countries often suffer greater impacts.
Exam tips
- Use a named cyclone case study with effects and responses.
- Explain why development affects vulnerability.
Common mistakes
- Confusing cyclones with tectonic hazards.
- Forgetting the role of preparation.
