Rainfall is one of the most important climate elements for agricultural production throughout the world [1]. 1.3: Tanzania IOD Rainfall Forecast Maproom for the OND (Oct-Dec) season 1.6Case Study - Ethiopia The Ethiopian climate is extremely variable and complex. For example, according to Gamachu [7] rainfall in Ethiopia has shown large variations across time and space, due to the complex topography and varying latitude of the country [7]. The annual rainfall ranges from 1,000 to 2,200 millimeters (40 to 87 inches). Partal T (2006) Trend analysis in Turkish precipitation data. As a final point, using gauge rainfall data is more reliable than Ethiopia has five climatic zones, characterized by altitude and temperature. drought assessment method by Agnew and Chappel (1999), seven a statistically non-significant increasing trend (increased by a Likewise, SRA during Belg and Bega season showed 50% a mean annual rainfall ranging between 790.3-1765.1mm.
