Weather hazards: tropical storms and UK extremes
Tropical storms need very specific conditions, which is why they form in a band and not everywhere. This lesson covers formation, structure and the UK's own extreme weather.

Weather hazards: tropical storms and UK extremes
Tropical storms need very specific conditions, which is why they form in a band and not everywhere. This lesson covers formation, structure and the UK's own extreme weather.
In a nutshell
Explain tectonic and weather hazards, their effects and the management of risk in contrasting places.

Formation and structure
Tropical storms form over ocean water above about 27°C and at least 50 metres deep, between roughly 5 and 30 degrees of latitude, where the Coriolis effect can spin rising air. Warm moist air rises, condenses and releases latent heat, driving further uplift. The eye is a column of descending air — calm, clear and low pressure — surrounded by the eyewall, where the fastest winds and heaviest rain occur.

Effects and responses
Storm surge, not wind, causes most deaths: low pressure raises the sea surface and onshore winds pile water against the coast. Immediate responses are evacuation, rescue and emergency shelter; long-term responses are rebuilding to higher standards, restoring mangroves and improving warning systems.

Climate change and storm behaviour
Evidence suggests warmer oceans give more energy and moisture, so the proportion of the most intense storms and their rainfall totals are increasing, and their distribution may extend polewards. Frequency overall is less certain — a nuance worth writing, because it shows command of the evidence.

UK extreme weather
The UK experiences flooding, storms, drought, heatwaves and heavy snow. Evidence for increasing extremes includes record-high temperatures in recent years and repeated named-storm sequences. Management is largely about preparedness: flood warnings, resilient infrastructure and adjusted building design.

Worked example
Model answer: 'Explain the formation of a tropical storm' (4 marks)
Sea-surface temperatures above 27°C evaporate large volumes of water, so warm, moist air rises rapidly and creates an area of low pressure at the surface. As this air rises it cools and condenses, releasing latent heat that warms the surrounding air and drives further uplift, strengthening the system. Air is drawn in at the base to replace it and is deflected by the Coriolis effect, causing the storm to rotate around a central eye of descending air.
