Characteristics of Heatwaves in Africa: Morocco 2000 and South Africa 2015/16

Abstract

Abstract. Heatwaves pose an ever increasing risk to African communities as exposure to heat extremes can have a drastic effect on individuals and in some cases can even result in death. This study presents new information about the characteristics of historical African heatwaves including a comprehensive synopsis of documented heatwave events from 1980 until 2020.Detailed research on heatwave case studies helps to inform the development of early warning systems and forecasting, which is an urgent priority. Here, the focus is on two reported heatwaves, Morocco 2000 and South Africa 2015/16. Both heatwaves feature in the Emergency Events Disaster database (EM-DAT) and include reported impacts, with the Morocco heat being the only hazard to be associated with an economic cost. In addition, these heatwaves reveal how the mechanisms behind them are closely influenced by synoptic systems and geography of their regions. Further, It is demonstrated there is some reporting by African Nations for heatwaves but that this needs significant improvement.
