tropical storms

• ho do tropical storms develop?

  • sea temp is 27 degrees
  • 5 and 30 degrees both and south of the equator
  • high wind speed
• how do tropical storm form?

  1. war air rises leaving an area of low pressure below
  2. it eventually cools, condenses to form large clouds
  3. it spins due the Coriolis effect
  4. it constantly gains energy from the warm air and it causes the storm to spin faster and generate higher wind speeds
  5. develops an eye in the centre - area of low pressure. its calm and cloud free
  6. the eye-wall is the most intense power area of the storm - high winds and torrential rain
• what is the eye of the storm like?

  calm and cloud free
• why does a tropical storm spin?

  due to the Coriolis effect
• what is the eye-wall conditions like?

  pirating rising air, strong winds, storm clouds, torrential rain, low temprature
• what are some primary effects of a tropical storm?

  • heavy rain causing freshwater flooding
  • electricity, water and communications damaged
  • people drowned In storm surge
  • crops destroyed
  • strong winds destroyed buildings
  • storm surge flattening buildings
• what is storm surge?


  large amounts of sea water to be pushed onto the coast
• what are the secondary effects of a tropical storm?

  • food shortages
  • drinking contaminated water
  • spread of disease due to unhygienic conditions
  • landslides
  • blocked roads
  • homelessness
• tropical storm


  a very large, spinning storm with high winds and torrential rain that forms in the tropics
• tsunami 


  a large wave caused by a large amount fo water being displaced when plates move
• How might climate change affect

  tropical storms?

  Greater storm intensity due to warmer

  oceans. Frequency expected to stay the

  same, though more severe (cat 4+)

  expected to increase. There is

  considerable uncertainly about the

  impact. Though a growing population and

  urbanisation in coastal locations has

  increased the potential risk to life.
• How do countries prepare for tropical

  storms?

  • Monitoring - use of satellites and

  aeroplanes to monitor weather systems

  • Prediction - monitoring changes in the

  formation and path of the tropical storm

  • Protection - constructing buildings that

  can withstand the impact of tropical

  storms

  • Planning - evacuation plans, education

  and creating exclusion zones.
• Give two immediate and long term

  responses to tropical storms.

  Immediate - evacuation, preparing

  properties, use of emergency storm

  shelters, distributing emergency aid

  Longterm - rebuilding properties,

  construction of buildings to withstand the

  impact of strong winds and storm surges,

  development of early warning systems.
• Give three effects of tropical storms

  Strong winds - destroy properties,

  infrastructure and crops

  Storm surges - cause flooding of property

  and farm land

  Landslides - caused by heavy rain

  Tornadoes - formed during tropical storms

  can cause devastation to property and

  infrastructure

  Aid - hampered due to communications being

  destroyed
