Revise

This week you will revise weather hazards and climate change. It would help if you covered the following:

• How the global circulation of the atmosphere leads to tropical cyclones (hurricanes and typhoons) in source areas and the sequence of their formation.
• Characteristics, frequency and geographical distribution of tropical cyclones and how these change over time.
• Reasons why tropical cyclones are natural weather hazards (high winds, intense rainfall, storm surges, coastal flooding and landslides).
• Different social, economic and environmental impacts that tropical cyclones can have on a named developed and a named emerging or developing country.
• Different responses to tropical cyclones of individuals, organisations and governments in a named developed and a named emerging or developing country.
• Characteristics of arid environments compared to the extreme weather conditions associated with drought.
• Different causes of the weather hazard of drought: meteorological, hydrological, and human (agricultural, dam building, deforestation).
• Why the global circulation makes some locations more vulnerable to drought as a natural hazard than others and how this changes over time.
• Reasons why droughts are hazardous.
• How the impacts of drought on people and ecosystems can vary for a named developed and a named emerging or developing country.
• Different responses to drought from individuals, organisations and governments in a named developed and a named emerging or developing country.

Use one of the three strategies below to revise these areas.
