Topic overview
What you need to know
Global atmospheric circulation redistributes heat and helps create distinct climate zones. Tropical storms need warm oceans, rising moist air and sufficient Coriolis force.
Exam tip
Use a clear sequence for storm formation and distinguish evidence for climate change from its natural and human causes.
Core knowledge
Key facts for Weather Hazards & Climate Change
Global atmospheric circulation
The worldwide movement of air that transfers heat from the equator towards the poles.
Tropical storm
A rotating low-pressure weather system with very strong winds and heavy rain that forms over warm tropical oceans.
Coriolis effect
The apparent deflection of moving air caused by the Earth's rotation.
Mitigation
Action that reduces the causes of climate change, such as using renewable energy.
Adaptation
Action that adjusts to the effects of climate change, such as building flood defences.
Enhanced greenhouse effect
Extra warming caused by rising concentrations of greenhouse gases from human activity.
