  • Why do tropical storms not form exactly on the Equator (latitude $0^{\circ}$)?

  • What is the primary source of energy that 'fuels' a tropical storm, allowing it to intensify?
    Solar energy absorbed by the sea surface.
  • A key environmental impact of the storm surge from Typhoon Haiyan was the contamination of coastal land. What was the main contaminant?
    Salt from the seawater, making the soil infertile for crops.
  • What is the minimum sea surface temperature (SST) generally required for a tropical storm to form and sustain itself?
    27- 28 degrees
  • What is an example of a secondary economic impact of Typhoon Haiyan?
