differences between north facing and south facing mountain slopes
Aspect (geography) Similarly, in the northern hemisphere a south-facing slope (more open to sunlight and warm winds) will therefore generally be warmer and drier due to higher levels of evapotranspiration than a north-facing slope.[3] This can be seen in the Swiss Alps, where farming is much more extensive on south-facing than on north-facing slopes. In the Himalayas, this effect can be seen to an extreme degree, with south-facing slopes being warm, wet and forested, and north-facing slopes cold, dry but much more heavily glaciated.

Slope Thus, a 45° rising line has a slope of +1 and a 45° falling line has a slope of −1.
The North Face The name was derived to evoke homage to the fact the north face of a mountain in the northern hemisphere is generally the coldest, iciest and most formidable route to climb.[4]
