Even in the hottest months (March to May), average highs rarely exceed 77 degrees Fahrenheit (25 degrees Celsius). As the study area is characterized by a wider altitudinal range , the difference in the spatial distribution of rainfall amount could be attributed to orographic nature of rainfall (Viste et al., 2013, Dinku et al, 2007). The timing and spatial distribution of rainfall, beyond total deficits, impacted livelihood activities such as agriculture and pastoralism during the 2015–16 drought in Ethiopia.

To attain this goal, Ethiopia needs to sustain the high growth episodes that have been observed over the last decade by deepening structural change in its economy. Source: Bryan et al. Vol. Awassa is 96 miles from Arba Minch, so the actual climate in Arba Minch can vary a bit. However, the detail spatial and temporal variability of rainfall over the horn of Africa in general and Ethiopia in particular is highly complex and not well known yet. - Coefficient of Variation of Mean Annual Rainfall ofEthiopia. - Mean Annual Rainfall Distribution ofEthiopia. The rainy season is of great importance not only to Ethiopia but to the countries of the Nile valley, as the prosperity of the eastern Sudan and Egypt is largely dependent upon the rainfall.

Their result also showed that the maximum, 3.2 15- minute Rainfall Rate Distribution in Ethiopia The cumulative rainfall rate distribution for ten locations in Ethiopia is calculated and plotted based on the data from NMA of Ethiopia at 15 minute integration time. To achieve this objective, long-term historical monthly rainfall and temperature data were recorded and analyzed for more than 100 years (1900–2016). Global Agriculture and Food Security Program draft application 8. Since rainfall is a variable climate element over space and time (Mishra, 2013), sufficient ground-measured rainfall data from evenly distributed rain gauge network is required in order to carry out reliable drought assessment studies.
