A semi-arid climate is characterised by hot summers and moder- ate to cool winters. During the winter June to Au- gust , the night temperature may fall below zero. However, a focus on rainfall averages may obscure the extreme variability of the rainfall in a semi-arid environment. A semi-arid ecosystem is governed by the annual seasonality of dry and rainy phases. Rain clouds build up in the summer months Figure 2.
