INTERPRETATION Flashcards
TEMPRETURE
- latitude
places further north are closer to the equator and usually have higher average temperatures than places in the further south
TEMPRETURE
- altitude
temp decreases with height. temp affects the type of farming that can take place in the area.
contour lines, trig beacons, spot heights and bench marks provide info abt altitude
TEMPRETURE
- distance from the sea
coastal locations have a maritime climate (cooler summer and warmer winter)
inland locations have a continental climate (hot summer and cold winter)
TEMPRETURE
- ocean currents
the warm Agulhas/Mozambique current raises temp along the east coast
cold benguela current cools temp on the west coast
TEMPRETURE
- aspect/slope
in SA, north facing slopes are warmer than south facing slopes
TEMPRETURE
- mountains and winds
mountains can shield places from the cold winds.
valleys can also funnel cold winds into farming regions on winter nights
TEMPRETURE
- urban and rural settlements
urban areas retain heat during winter nights because of the heat island effect
rural areas Experience a far greater terrestrial radiation, which results in lower winter night = affect crops
RAINFALL
- non perennial rivers
dashed blue line
seasonal rainfall
Lots of dams
Lack of veg
RAINFALL
- perennial rivers
solid blue line
high river density indicate high rainfall
No dams
High veg
RAINFALL
- in SA
east = most likely to have higher rainfall
west = decrease
RAINFALL
- rainforests
evidence of large areas being used to cultivate land, which might suggest high rainfall
RAINFALL
- canals and dams
suggest that the area is dry or has seasonal rainfall and there us a need to store water
WIND
- orientation of airport runway
this will indicate the direction of prevailing wind
WIND
- indicate prevailing in a valley during the day
have to find this prevailing wind either at day or not
WIND
- windbreaks
the trees can also indicate wind
roots are in the ground making it safe from any soil erosion and growth before end of term
