DO NOW: add complete labels.

The calm part is the eye.

Fast convection currents

Cool dense air

Trade winds from NW in

northern hemisphere or

from SW in southern

hemisphere move towards

equator.

Coriolis force causes winds to

rotate.

High hurricane speed winds and heavy rain

occur here.

Warm moist air from the tropical

seas

Tropical storms form over oceans with temperatures of +27˚C and sea depth of at least 60metres where water can evaporate

and fuel the storm.

What are the natural processes that allow tropical storms to form?

• 29th August 2005• USA (formed as Category 5 in Bahamas first, made landfall

in USA as Category 3 hurricane)• Worst affected = Florida, Louisiana (especially New Orleans

which is 2-3metres below sea level naturally)• 155mph winds• 80% of New Orleans city evacuated• Breached levees (flood defences) with a 10m+ storm surge• 1200 drowned. 600 died from disease such as cholera

(unusual for MEDC). Total deaths at least 1833.• 1million homeless (800’000 for over a year in temporary

housing). Residents evacuated to superdome. • Criticised for poor government response (e.g. George Bush

slow to declare emergency or launch FEMA rescue)• $90.9billion damages (costliest disaster in US history).

HOW DO I WRITE A PERFECT 9 MARK CASE STUDY ON THIS?

Point 1Hurricane Katrina in August 2005 was the worst disaster in US

history.

Point 3Critics say that the impacts were made

worse by government mismanagement

Point 2When the storm hit Louisiana it was a Category 3 scale

depression.

Why do people live in areas at risk of tropical storms?

1. Find a map that shows the distribution of tropical storms

2. Describe the location / pattern of the worst affected areas. Choose specific countries.

3. Suggest reasons (based on research) why people choose to live in risk areas (social, economic, environmental reasons). What benefits?

How to prepare for a tropical storm

• Create a guide aimed at Louisiana residents.• The aim is to advise local residents how they should

prepare for a hurricane• Must also be understood by non-English speakers

(Louisiana has a high Hispanic population). So think about images & translations.

• Include:– Possible effects of hurricanes:

• Storm surge• Wind speed

– Evacuation plans – what to pack, where to go– Emergency supplies at home– Protecting homes and businesses from damage– Protecting against looting

Making connections: SOLO hexagons

SOLO Hexagons1. Mindmap all you can remember about the

tropical storms including the case studies

2. Write each point out onto a hexagon

3. Now try to match these hexagons up to other hexagons to MAKE LINKS

4. CHALLENGE: how many connections can you make? Try for at least 3 sides of the hexagons to connect.

5. Use the pattern to structure your extended writing

e.g. Here’s one I made earlier…

Cyclone Nargis• Worst natural disaster in Burma / Myanmar• Began as an intense tropical depression on April 27th 2008 in the Bay

of Bengal. Made landfall over Irrawaddy delta in Burma on May 2nd.• Meteorologists initially thought storm would track over Bangladesh• However, the storm changed direction and headed towards Burma:

this was not realised immediately due to a lack of prediction and monitoring equipment in the region

• Category 4 storm on the Simpson–Saffir scale• 130-145mph winds. 600mm of rain fell.• 138’000 people were killed• $10 billion damage occurred• 75% of hospitals and clinics were badly destroyed or damaged• Diarrhoea, dysentery & skin infections afflicted the survivors who

were crammed into monasteries, schools and public buildings for safety

• Burma’s military government was resistant to foreign aid. UK donated £17million but much was lost on black market & looting.
