Rainfall Patterns

 

The results in the trends of annual rainfall performed for the period 1921-2015 for South Africa indicate that though South Africa’s rainfall patterns have changed, statistically the annual average rainfall has not significantly changed.

 

Though climate change is impacting rainfall patterns, this is impacting more the distribution of rainfall and not necessarily the amount of annual rain that South Africa receives.
