Q

TROPICAL STORM - typhoon HAIYAN 2013 - in the Philippines in Asia

A

TROPICAL STORM - Case Study - HAIYAN in the Philippines in Asia

  • waves 7 metres high battered the coast - widespread flooding - extreme wind speeds - size 5

PRIMARY EFFECTS

  • 6,300 people died
  • 30,000 fishing boats destroyed (effects business/economy)
  • main airport destroyed (effects business/economy)

SECONDARY EFFECTS

  • lack of shelter, poor water lead to disease

Q

Immediate & long term responses to a TROPICAL STORM eg Storm Haiyan in the Philippines in Asia

A

IMMEDIATE RESPONSES to tropical storm eg Haiyan in the Philippines in Asia

  • Food (250,000 litres of water were distributed) & temporary shelter supplier by international help
  • AIRCRAFT & HELICOPTERS provided to help with rescues
  • Evacuation centres set up
  • removed dead bodies to prevent disease

LONG TERM RESPONSES to tropical storm eg Haiyan in the Philippines in Asia

  • Rebuilding of roads, buildings and bridges
  • New homes built in areas less likely to flood
  • improve storm forecasting to limit the damage of a future storm

Q

The responses to a tropical storm will depend on:

A

What responses are needed depends on:

  • has the city or countryside been effected?
  • is it in a HIC or a LIC/NEE? (ef NIC/NEE will rely on foreign help and aid)
  • HICs made have some storm predicting tech so people can made preparations to leave before the storm hits
  • Individuals may respond by helping their immediate family or put up flood defences
  • Governments will need to lead the national rebuilding & send out supplies of emergency aid

Q

Is prediction the most important factor in reduction effects of tropical storm?

A

Need a package of measures to help reduce the effects of tropical storms?

  1. SATELLITE & RADAR to TRACK & PREDICT the development of the storms + COMPUTER SOFTWARE MODELLING to track path
    (but available to all countries - HIC but what about NIC/NEE - EXPENSIVE TECH
    Useful for urban where many people/buildings but it is still useful in rural/countryside?
    IMPORTANT SO EVACUATION PLANS CAN BE PUT INTO ACTION - SAVES LIVES & PROTECT PROPERTY/MOVE ANIMALS
  2. PLANNING & PREPARATION
    • have EVACUATION plans in place so EVERYONE KNOWS IN ADVANCE where to go QUICKLY - PROTECT LIFE
    • board up windows/sand bags/move animals - PROJECT BUSINESS
    • GOVERNMENTS have a CENTRAL CO-ORDINATED PLAN
    • survival pack already distributed with food/water/medicine ready for people to grab in an emergency
    • NEW BUILDINGS - with stand STORM DAMAGE

Features of a TROPICAL STORM:-

A

Features of a TROPICAL STORM:-

  • CIRCULAR STRUCTURES - 100’s of km WIDE
  • Strongest part is the centre called the EYE can be 50km across

Q

What happens if TEMPS RISE: -

A

IF TEMPS CONTINUE to RISE:-

  • Tropical Storms are only found where the waters are 27 degrees C - if temps rise more tropical storms will there form around a wider area around the equator.

Q

Features of TROPICAL STORMS

A

TROPICAL STORMS

  • only found over waters of 27 degrees near the EQUATOR where the weather is warmer
  • CIRCULAR STRUCTURE - 100’s km wide
  • Centre is EYE can be 50km across
  • EYE WALL is the STRONGEST part of the storm because the AIR moves FASTER and pulls in OCEAN WATERS to FUEL the storm
  • VERY STRONG winds, TORRENTIAL rain & low temps
  • the path of the storms are westwards
