VALLEY CLIMATESTHE MICRO-CLIMATE OF VALLEYS [SLOPE ASPECT]

During the southern hemisphere’s winter solstice [June], the sun’s rays
shine directly on the Tropic of Cancer and wouldn’t reach the Antarctic
circle. The opposite occurs in the summer solstice. The sun’s rays strike
the surface at an angle [angle of incidence]
The angle varies:
• Day: sunrise and sunset – low
Apparent migration of
Noon – high
the sun
• Season: summer – high
Winter – low
, The same amount of energy from the sun has to heat a smaller surface
area at A than at C, and therefore temps will be higher at A than C
• Aspect – the direction that a slope faces
• In the southern hemisphere, the sun’s rays strike the north facing
slopes more directly than the south facing slopes
• In winter, the north facing slopes will be warm
• Sun’s rays come from the north
• In winter, both slopes will be cooler than in summer, because the
sun’s rays are at a greater angle
- The angle in winter means that
lower parts of the south facing
slopes and the bottom of valleys
get no sun
- They are in a shadow zone
• Soils on hotter, north facing slopes
are dryer
• South facing – moist, cooler soils
