Climatology

The temperature difference between the centre of the city and the rural area is:

• 23°C

• 3°C

• 4°C

• 30°C

Identify the solution that does not apply to addressing urban heat island problems

• roof-top gardens

• increase in public transport

• decentralisation of industries

• increase in air conditioners

The profile shape of an urban heat island is . . . during a summer day.

• concentrated and flat

• extended and mushroom

• dome and mushroom

• flower and dome

An example of artificial heating sources in the city centre:

• air conditioners

• lack of natural vegetation

• lack of water bodies, such as lakes

• pollutiion

The urban area will experience . . . cloud cover with a/an . . . in precipitation than the rural area.

• less-decrease

• more-increase

• less-increase

• more-decrease

Why does Cold fronts in Mid-latitude Cyclone moves eastwards?

• moved by tropical easterlies

• moved by westerlies

• moved by gravity

• move by the polar easterlies

Why does a cold front in a Mid-latitude cyclone produce heavy rain?

• rapid rising of warm air and cumulonimbus clouds

• rapid descend of cold and cirrus clouds

• rapid divergence of air

• rapid convergence of air

Which of the following are economic impact of a cold front in a Mid-latitude cyclone?

• Damage to vegetation, crops and livestock.

  -Damage to shipping, offshore and coastal structures.

  -Costly to rebuild.

  -Negative influence on GDP.

  -Unemployment.

  -Creates opportunities for employment for rebuilding.

  -Impacts negatively on tourism.

• Flooding of low-lying coastal lands.

  -Coastal erosion.

  -Saline intrusion of low-lying coastal lands.

  -Waterborne disease such as cholera.

  -Ecosystems are disrupted .

  -Food chains and food webs are destroyed.

Why does it snow during occurrence of Mid-latitude cyclones?

• Cold fronts interact with moist air and when it rise to high altitude snow can develop

• Because it close to the poles

• Cold fronts and snow both come from clouds

• Because its in a valley
