Paper 1: Living with the physical environmentQ1 Section A: Weather hazards

Revision of tropical storms – the structure and the effects of climate change

This is revision so you will need to use your exercise books to help you complete some or all of these tasks. If you find you are missing work in your exercise book see your teacher or borrow the notes. If you are unsure of the work, ask for help. Work needs to be fully completed and handed in on time.Revision is the key to doing well in your examinations - the more effort you put in, the better you will understand the work in readiness for your Paper 1 examination.You will need to make some tables bigger so check that before you print the work.What is the structure of a tropical storm?

Write these statements into the correct order in the boxes below (DO NOT NUMBER THEM – WRITE THEM OUT):

These are the weather statements but THEY ARE NOT IN THE CORRECT ORDER:

Summarising your understanding (optional task)

Sketch your own larger version of the diagram of a tropical storm and annotate it with the main weather conditions you would experience as it passes over you.

How climate change might affect the distribution, frequency and intensity of tropical storms

a) How has climate change (global warming) changed the DISTRIBUTION of tropical storms?

Use the words in the boxes to complete the sentences below:

50 not 0.25new 27 Equator

Sea surface temperatures have increased by _____ to 0.5˚c over the last ____ years. This might have the following effects on tropical storms:In the future, some ____ areas may be affected by tropical storms because the latitude of oceans with a temperature of ____˚c (the temperature needed for tropical storms) may spread further north and south of the ______________. It won't be by much so the regions that get tropical storms is _____ expected to change much.

b) How has climate change (global warming) changed the FREQUENCY of tropical storms?

Describe the overall trend in the number of hurricanes reaching the USA.Hint: Decrease or increase? Use numbers to support your opinion.

c) How has climate change (global warming) changed the INTENSITY of tropical storms?

Use the graph: What does the Power Dissipation Index measure?

Sea surface temperature and the Power Dissipation Index correlate well. What does this mean? Hint: Look at the lines on the graph.

Why does higher sea surface sea surface temperatures mean more intense tropical storms? Hint: Think about energy and use your revision notes completed so far.

Climate change may also affect the level of storm surges and have a higher impact on settlements. Use your books and the pictures to fill in the gaps:

Sea level will rise because of ___________ expansion.

Sea levels rising means ____________________ will become higher.

The atmosphere is getting warmer (and has more energy) so the air can hold more water. So there will be more rainfall and more _______________ as the atmosphere has more energy.
