MODIFICATION OF RURAL CLIMATES

MICROCLIMATES

• A CLIMATE OF A SMALL GEOGRAPHICAL AREA AND OFTEN
  DISTINCT FROM NEIGHBORING AREAS DUE TO
  DIFFERENCES IN THE FOLLOWING

HUMIDITY

WHICH PROCESSES CAN LEAD TO THE MODIFICATION OF
RURAL CLIMATES?
11
deforestation

• This leads to a replacement with grasslands.

12

• This leads to more solar radiation and therefore
  more heating.
• This results in a reduction in transpiration and
  less humidity.
• This leads to an increase in surface
  temperatures.
• This leads to a decrease in precipitation.
• This affects the water cycle.

13
Rainforest destruction in the Amazon
14
AFFORESTATION

• Fewer extreme temperatures due to under canopy.
• Reduction of water loss

15
Afforestation in New South Wales, Australia
16
FARMING PRACTICES

• More methane gas emissions which can lead to
  local and global warming.

17

• Greater soil erosion which can lead to
  desertification and more local warming.

18

• Greater water loss which can lead to more
  evapo-transpiration
• Ex droughts in China

19
DAM CONSTRUCTION
20

• A LARGE RESERVOIR MAY INCREASE HUMIDITY AND
  PRECIPITATION
• A LARGE RESERVOIR MAY MODERATE THE TEMPERATURES
  OF THE LAND AROUND ITS BANKS
• A LARGE RESERVOIR MAY ENCOURAGE STRONGER WINDS
