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.

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.

This is the part you'd do in your book at school. Pick the pieces below, write here or on paper, and photograph anything you draw or work out.

Case study

Flooding on the River Calder

The town of Harbrook sits where a steep valley opens onto a flat floodplain. In December 2015, 120 mm of rain fell in 36 hours onto ground that was already saturated. The river rose 2.4 m in five hours, and 380 homes and 54 businesses flooded. Two roads and the railway closed for eleven days.

Geographers pointed to physical causes — steep slopes, impermeable rock, heavy rainfall — and human causes: moorland drained upstream, new housing built on the floodplain, and drains designed for smaller storms.

Since then the town has planted 40 hectares of woodland upstream, built leaky dams in small streams, and raised flood walls to 1.8 m. In the storm of 2020 the peak river level was 0.3 m lower and 40 homes flooded, not 380.

Written for Good Learning Co.

Reading questions

  1. List two physical and two human causes of the 2015 flood.
  2. Explain how planting woodland upstream lowers the river's peak level.
  3. Using the figures, judge how successful the scheme has been. Quote data in your answer.
