Tropical storms

• warm water (27 degrees or above) begins to rise from the surface of the ocean, creating areas of extreme low pressures which increases the wind speeds. This air then condenses to form large clouds, releasing lots of energy, which fuels the storm. The cooling air then moves away and more water is able to rise. The low wind shear prevents clouds from scattering. The storm spins due to the Coriolis effect (a force experienced due to rotation of the Earth). They spin clockwise in the northern hemisphere and anticlockwise in the southern hemisphere.
• What are the 3ps for reducing the effects of tropical storms?

  1. planning

  2. Prediction

  3. Protection
• What is involved in planning for a tropical storm?

  1. Future developments 2.Evacuation routes prepared

  3. emergency services prepare by practicing them

  E.G: after typhoon haiyan volunteers started rescue simulations
• What is involved in protection for a tropical storm?

  1. Better infrastructure to withstand storms
  2. Flood defences

  E.G: mangrove forests planted to act as a nateral defence barriers.
• What is involved in prediction for tropical storms?

  1. Storms monitored and paths predicted to give people time to evacuate and authorities decide places to evacuate
  2. E.G: predicting typhoon haiyan helped authorities to evacuate people.
