Answer

1

a)

• Named Hadley Cell rising and falling between 0 and 30 degrees N and S
• Circular pattern of rising and descending air and indicated for the other cells too
• Cells could be named

b) Heat source:

• influence on the jet stream
• thinning of tropopause towards the poles
• differential heating and cooling of the air

c) Air rising:

• heating of surface
• high insolation and uplift
• air masses meeting etc..

Cloud type

• at 0 degrees cumulus / cumulo-nimbus
• further north stratus
• different heights of clouds

Precipitation

• short torrential rainfall
• some slight rain

d) Any three from

• increase in violent and unpredictable weather - flooding and hurricane intensification
• when warm water replaces cold there is decimation of fishing grounds
• drought in normally lushly vegetated areas
• agricultural production plummets
• or other suitable answers

e) Effects on agriculture, fishing, construction, transport, power, business and retail, leisure and sport, health.

Could be + and - effects.

a) General impact points

• temperature increase affects precipitation
• soil moisture drops
• drought problems
• agricultural output drops especially in poorer tropical countries
• increased cloud cover effect isolation, shading and cooling the ground
• seas level increases through ice melt and thermal expansion of the sea
• wetlands dry up
• ocean current change
• jet streams change position
• extinction of natural flora and fauna, in various countries
• increase in tropical diseases, and so on...

Consequences - 'economic and social'

• snow-cover reduction - tourism / skiing affected
• water demand and supply affected
• location of fish shoals change
• regional weather shifts
• more intense, less-predictable storms
• pests spread
• different crops grown

b) General points using the UK as the exemplar

• temperate climate becomes more Mediterranean
• less-frequent heavy rainstorms replace frequent rain and drizzle
• insect infestation increases
• seas level rises exacerbated in the SE of the UK
• Pleistocene isostatic re-adjustment
• warmer S. UK would support citrus groves and cooler Scotland dairying
• coastal area inundated, nuclear power stations under threat, coastal industry retreats inland and the coastal population migrates too
• salt marsh disappears
• coastal erosion appears

Of course the answers could focus on any country or continent
