tropical storms.

3. LO: To explain how climate change might affect the distribution, frequency and intensity of
tropical storms.
1. Every year Europe has many hurricanes.
2. A cyclone and a hurricane are the same thing.
3. Most tropical storms occur in the Southern Hemisphere.
4. In a hurricane winds blow in a clockwise direction.
5. Winds in a tropical storm can blow over 100kph.
6. Tropical storms are never more than 100 miles wide
7. In the eye of the storm, cold air sinks and there are no clouds.
8. Temp of the ocean needs to be over 27c for hurricanes to form.
9. Tropical storms rotate due to the Coriolis effects.

4. LO: To explain how climate change might affect the distribution, frequency and intensity of
tropical storms.
 How powerful the
storm is (measured
by the Saffir-
Simpson scale.
 How often
something occurs (in
this case, tropical
storms.)

From the graph I can tell that Hurricane
intensity has (increased/decreased) over
the last ____years.
The evidence for this is in the data. The
years with the highest intensity storms are
recent, such as in 2005 when the PDI
reached _______.
Further evidence can be from the year
1972 when SST’s were only ______ and the
PDI was about. There is an anomaly though
for the year _____ when SST was
(high/low) whilst PDI was (low).

9. As the temperature increases, sea
levels will rise due to thermal
expansion.
The impact of rising sea levels will mean storm
surges are expected to
become higher.
A warmer atmosphere will mean
the air can hold
moisture.
Heavy rainfall is expected
to increase.
Flooding during a tropical
storm is expected to be more
destructive.

Using the information on the next 2 slides & in the book on pages 26 &
27 try to complete each section of your sheet.
Word Box
Distribution = pattern of where
they happen
Frequency = how often they
happen
Duration = How long they last
Intensity = How strong the
storms are

11. Climate change will alter the conditions that cause tropical storms:
• As the temperature increases, sea levels will rise due to thermal
expansion. The impact of rising sea levels will mean storm surges
are expected to become higher.
• A warmer atmosphere will mean the air can hold more moisture.
Heavy rainfall is expected to increase. There fore flooding during a
tropical storm is expected to be more destructive.
LO: To explain how climate change might affect the distribution, frequency and intensity of
tropical storms.

12. Climate change might have the following effects on tropical storms:
• A wider distribution area as the latitude of oceans with a
temperature of 26.5 oC or more spreads further north and south of
the equator
• The intensity of tropical storms increasing by 2-11% as higher
ocean temperatures generate more energy
• The actual number of tropical storms may remain largely the same
but there might be a greater number of extremely intense storms
• An increase of up to 20% in the amount of rainfall within 100 km
of the eye of the storm

LO: To explain how climate change might affect the distribution, frequency and intensity of tropical storms.
Points to include:
• Tropical storms only form in areas
where sea temperature is 26.5 oC
or higher.
• The graph shows an average
global temperature increase of
0.5 oC over 50 years. This may
have caused ocean temperatures
to increase.
• If the warming continues, larger
areas of ocean will be 26.50C or
warmer.
• This means the area affected by
tropical storms will increase in
size, with areas at higher
latitudes affected.

18. Positive– Write down areas of the lesson you have been successful in,
name the key terms or named examples you are now confident in using. What
areas have you worked hard on improving? Named examples, geographical
terms, facts, statistics, explanations, comparison?
Error – Write down areas you are less confident with, certain case studies
or examples you may need to go over again to fully understand. Do you use
enough explanation using named examples and facts in all your answers? Do
you push yourself or are you reliant on the teacher for guidance or pressure
to progress?
Next – Where can you move yourself forward over the next lesson, week or
month. What are you going to start including which will improve your detail
and work?
