(a)  

Name the scale used to measure the intensity of a cyclone

Answer explanation

Saffir-Simpson Hurricane Wind Scale

How has climate change increased the frequency and the severity of cyclones?

Answer explanation

Human activities, such as burning fossil fuels and deforestation, have increased the levels of greenhouse gases in the atmosphere. This has led to a warming of the Earth's surface, which can contribute to the formation of tropical cyclones by providing warmer ocean waters and more favorable atmospheric conditions.

Urbanisation: The growth of cities and other urban areas can alter the natural landscape and disrupt the balance of the local climate. This can lead to changes in wind patterns, rainfall patterns, and surface temperatures, CLIMATE CHANGE:

which may influence the formation and behavior of tropical cyclones.

Land Use Changes: Changes in land use, such as deforestation and the conversion of natural landscapes to agricultural or urban areas, can affect the local climate and disrupt the natural water cycle. This can lead to changes in soil moisture, evapotranspiration rates, and atmospheric moisture, which may influence the formation and behavior of tropical cyclones.

Coastal Development: The construction of buildings, roads, and other infrastructure along coastal areas can alter the natural landscape and disrupt the natural flow of water. This can lead to changes in the intensity and direction of storm surges, which can exacerbate the impacts of tropical cyclones.

Outline the economic factors that could increase or decrease someone's risk level if a cyclone was to occur

Answer explanation

Wealth and poverty: Wealthy individuals and communities may have more resources to prepare for and recover from tropical cyclones, while poor individuals and communities may lack the resources to do so.

Industry and infrastructure: Areas with heavy industry or critical infrastructure (such as power plants or airports) may face greater economic impacts from tropical cyclones.

Insurance coverage: Insurance coverage can affect the ability of individuals and communities to recover financially from tropical cyclones.
