“…From northern Sudan all across Egypt, rainfall is negligible (below 50 mm except along the Mediterranean coast). This general distribution reflects the latitudinal movement of the inter-tropical convergence zone (ITCZ) which never reaches Egypt and northern most Sudan, stays only briefly in central Sudan and longer further south (Camberlin, 2009).…”

“…Changes in sea surface temperature (SST), on the other hand, can generate imbalance in the heat-flux field which can also bring about anomalous atmospheric circulation and rainfall patterns (Horel, 1982). Variations of SSTs over the Indian and South Atlantic oceans play a significant role in the variations of annual rainfall over the Nile Basin (Camberlin, 2009). To gain an insight into the consequences, on rainfall variability, of pressure changes (occurring over the different oceans) and anomaly in circulation due to SST, a number of readily and freely available climate indices were used.…”

“…Because the rainfall totals for ONDJF are larger than those for MAM, it was taken as the main wet season for variability analysis. According to Camberlin (2009), large variations in long-term mean rainfall statistics across the Nile Basin are due to its great latitudinal and longitudinal extents. Based on Fig.…”

“…According to Camberlin (1997) the part of the Nile Basin that receives the summer rains, i.e., JJAS season, has a strong connection with the Indian monsoon. A deepened monsoon low increases the pressure gradient with the South Atlantic Ocean, resulting in strengthened moist south-westerlies/westerlies over Ethiopia, Sudan, and Uganda (Camberlin, 2009). The tropical easterly jet associated with the intense Indian monsoon is another factor, especially for the rainfall over the Sahelian belt (Grist and Nicholson, 2001).…”

“…The riparian countries of the Nile Basin include Burundi, Rwanda, Uganda, Kenya, Tanzania, South Sudan, Democratic Republic of Congo, Sudan, Eritrea, Ethiopia, and Egypt. The climate of the Nile Basin is characterized by a strong latitudinal wetness gradient (Camberlin, 2009). There is a spatially contrasted distribution of mean annual rainfall over the Nile Basin.…”

Abstract. Spatiotemporal variability in annual and seasonal rainfall totals were assessed at 37 locations of the Nile Basin in Africa using quantile perturbation method (QPM). To get insight into the spatial difference in rainfall statistics, the stations were grouped based on the pattern of the long-term mean (LTM) of monthly rainfall and that of temporal variability. To find the origin of the driving forces for the temporal variability in rainfall, correlation analyses were carried out using global monthly sea level pressure (SLP) and sea surface temperature

Perspectives on CMIP5 model performance in the Nile River headwaters regions

Ranking the performance of global climate models (GCMs) is a notoriously difficult exercise. Multi‐model comparison studies nearly always show that each model has strengths and weaknesses relative to others, and for many purposes the multi‐model ensemble mean delivers better estimates than any individual model. Nevertheless, in regions like East Africa, where there is little consensus between models on the magnitude or sign of 21st century precipitation change, the multi‐model ensemble mean approach to climate projection provides little value for adaptation planning. Here, we consider several possible frameworks for model evaluation and ranking, and assess the differences in performance of a subset of models participating in the 5th Coupled Model Intercomparison Project (CMIP5) according to each framework. Our test case is precipitation in the Nile River headwaters regions. We find that there is little consistency in the relative performance of models across frameworks based on amount and seasonality of precipitation, interannual precipitation variability, precipitation teleconnections, and continental scale climate patterns. These analyses offer some guidance on which GCMs are most likely to provide meaningful results for specific applications, but they caution that any effort to select ‘best performing’ GCMs for the Nile River basin must carefully consider the purposes for which GCMs are being selected.

The future of the Nile: climate change, land use, infrastructure management, and treaty negotiations in a transboundary river basin

The Nile is one of the world's major rivers; its basin is shared by 11 countries and is home to some 300 million people. This article reviews the multidisciplinary literature on the Nile to understand more about the outlook for this geopolitically significant river basin. I start by synthesizing the key results from recent climate change modeling studies, which show a warming trend for the basin, but considerable uncertainty regarding the direction of precipitation and streamflow change. I explore how different actors within the Nile Basin are perceiving and responding to climate change. Second, I look at the significance of land use, both to basin hydrology and as a driver of water demand. I highlight contemporary land use changes that could impact flows within the Nile Basin. Third, I examine the role of infrastructure in influencing the magnitude and temporality of flows along the river. I focus, in particular, on the Grand Ethiopian Renaissance Dam, its projected impacts, and the concerns it has generated. Finally I explore the geopolitical context of the basin, and the ongoing conflict over water sharing agreements. I look at the treaty currently on the table, the Cooperative Framework Agreement, and the political issues it has raised. In bringing together this diverse literature, the article offers a timely and multifaceted insight into the varied factors that will shape the future of the Nile.
