Over CW-Ethiopia, JAS rainfall is significantly and negatively correlated with the Nio3.4, CIndO and IOD modes of SST variability. Int J Climatol 29:10751100. Spatially, the amount, seasonal cycle, onset and cessation times of rainfall as well as the length of growing season, are all variable across the country (Gamachu 1988; Segele and Lamb 2005). (2011a) also reported the presence of some correlation between SSTs over the southern Atlantic Ocean and Gulf of Guinea and Ethiopian JuneSeptember rainfall. CLIMATE CHANGE AND ITS IMPACTS ON PEOPLE AND ECOSYSTEMS IN CENTRAL RIFT VALLEY, ETHIOPIA | Climate change impacts people's livelihoods climate change impacts ecosystem services how do people . The climate of West Africa is expected to become more arid due to increased temperature and uncertain rainfall regimes, while its population is expected to grow faster than the rest of the world. Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. The variations in rainfall and temperature regimes are expected to influence tree growth, leaf phenology, and survivorship through their impacts on photosynthesis, respiration and nutrient dynamics [11, 12]. However, such a study is lacking in many basins of Ethiopia. We also note that HadGEM3-GA3.0 is a climate model that was under continuous improvement (Hewitt et al. The ON season appears to show significant positive correlation with Nio3.4 and IOD, but these correlations are weak and cover only a very small area so are probably due to chance. The analyses revealed that sheep (r = 0.535, P < 0.05) and cattle (r = 0.512, P < 0.05) were negatively affected by climate change. The "1.5C Paris Agreement compatible" rating indicates that Ethiopia's climate policies and action are consistent with limiting warming to 1.5C. The main findings of this study are summarised as follows. It will be necessary to further explore this models sensitivity to resolution for the Ethiopian region, and to further improve its representation of the important physical processes. 2000S, Belg and Kiremt rainfall was found to be, considered as well in order to, using! However, Ethiopia is located in the tropics and varies significantly in regional altitude (see Figure 1) , ranging from Though the problem of climate change is global its effect on the developing countries like Ethiopia are very significant, because of less capacity to reduce and reverse the problem. Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia (Conway et al. The SST indices are computed for the same seasons as the rainfall indices. 2011). doi:10.1002/joc.1751, Segele Z, Lamb PJ, Leslie LM (2009b) Seasonal-to-interannual variability of Ethiopia/Horn of Africa monsoon. Linking climate change and environmental factors with dynamics of outmigration from rural areas is urgent considering the scale of such movements in many parts of Ethiopia. They found that we'll likely cross threshold for dangerous warming (+1.5 C) between 2027 and 2042. endstream endobj 169 0 obj <>stream 2011; Hewitt et al. More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century. 0000014469 00000 n In the Central Rift Valley of Ethiopia, climate change and variability is manifest through frequent droughts and floods, erratic rainfall and fluctuating mean temperature . Therefore, in order to help policymakers and developers make more informed decisions, this study investigated the temporal dynamics of rainfall and its spatial distribution within Ethiopia. Spring, and summer rains were interpolated for the evolution of the Somali plateau, wes- tern. hb```b``a`c` @1vI^d s h@! ;Q6 ?pz[h$2t>LEH@Rgsunz/JXECxnNt{, 1lguw%YO#$xITs+1/l4}JXyLt%Onid JV+s g3wtt@|l\`IAA TJ9({ntXZ(xOi- d`f1a()+ s4=&$'03b1Lx,F">Q)L/_2NfcL`S}0d20|baZ9q We calculated mean monthly values from these models for each of the rainfall regions (shown in Fig. Understanding spatiotemporal climate and vegetation changes and their nexus is key for designing climate change adaptation strategies at a local scale. MRD 8:131138. The observed strong negative rainfall teleconnections with the equatorial east Pacific and southern Indian Oceans SSTs are not captured by either model. 2006; Ummenhofer et al. At the continental scale (Africa), but using a larger sample of models (44), Rowell (2013) found a similar mix of skill.

Spatial and temporal 2 H and 18 O isotope variation of contemporary precipitation in the Bale Mountains, Ethiopia Full-text available Article Feb 2020 Bruk Lemma Debebe Seifu Kebede Sileshi. 1) long cycle crop growing area of the country. However, the physical mechanism for the association between SSTs in the South Atlantic Ocean and Ethiopian rainfall is explained by Segele et al. (2009a, b); Diro et al. Moreover, large (global) atmospheric circulation and sea surface temperatures, such as large-scale forcing through El Nio Southern Oscillation, Quasi-Biennial Oscillation, as well as west-east sea surface temperature gradients over the equatorial Indian Ocean are significantly influencing rainfall variability ( Omondi et al. Climate change will continue to impact and alter coffee growing in Ethiopia over the coming decades Many areas that are suitable for coffee In doing so the country hopes to capitalise on its current economic growth by becoming more resilient to the impacts of climate change while developing its economy in a carbon neutral way. We also identify three new regions (Central and western Ethiopia, CW-Ethiopia; Southern Ethiopia, S-Ethiopia; and Northeast Ethiopia, NE-Ethiopia) that are complementary to those previously defined here based on distinct SST-rainfall teleconnections that are useful when predicting interannual anomalies. In the far south, far west and far east of the country, average daily temperatures often exceed 85 degrees Fahrenheit (30 degrees Celsius). Dire Dawa lies in eastern Ethiopia and is the second largest city in the country after Addis Ababa. Find other country and regional climate risk management resources here. We have ambitious plans for NOAA Climate.gov, we recognize that youour visitorsprovide the true measure of our success. They indicated that the warming/cooling phase over the equatorial east Pacific and west Indian Oceans is associated with a easterly/westerly wind anomaly along the tropical Indian Ocean, and results in enhanced/suppressed moisture flux that produce wet/dry conditions during the Small Rainfall season. rainfall on the basis of gridded data and interpolation. (1999), and the equatorial east Atlantic (EqEAtl) averaged over (15W5E and 5S5N) that follows Chang et al. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. A greater aspect of our weather and climate is its variability. & Bewket, W. Teleconnections between Ethiopian rainfall variability and global SSTs: observations and methods for model evaluation. Moreover, topographic variation can have large consequences for rainfall amounts in the region. Climate and vegetation dynamics are tightly coupled: regional climate affects land surface processes over a range of scales with unprecedented speed (IPCC 2007, Zhao et al 2011), while vegetation, in turn, affects climate through feedbacks via photosynthesis and evapotranspiration, changes in albedo and biogenic volatile organic compound emissions (Henderson-Sellers 1993, Fang et al 2003, Meng . The remaining length of time considered for our analysis is 74years for HadGEM2-N96 and HadGEM3-GA3.0-N96, and 59years for HadGEM3-GA3.0-N216. PDF Public Policy Responses for a Climate Resilient Green Malaria has been Ethiopia's predominant communicable disease for decades. 0000001196 00000 n A region's weather patterns, usually tracked for at least 30 years, are considered its climate. This is also a prime time for bird watching. Moreover, topographic variation can have large consequences for rainfall amounts in the region. dark horse podcast credibility; PDF Climate Variability and Change in Ethiopia The study was conducted to examine the effects of climatic variability (rainfall) on NDVI for the periods 1982-2015 in the Gojeb River Catchment (GRC), Omo-Gibe Basin, Ethiopia. (2011); and Martin et al. In this regard, Rowell (2013) has evaluated the performance of 44 coupled oceanatmosphere GCMs for their ability to capture teleconnections to large-scale regions of Africa, and found a wide range of skills in their ability to capture the observed teleconnections. The regional classifications by previous studies (e.g. Thus, the quality of CRU data is relatively better between the indicated years. Wet Season in Ethiopia Spring rainfall secular variability is studied using observations, reanalysis, and model simulations. 2004; Korecha and Barnston 2007; Diro et al. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. The FMoH achieved significant declines in malaria mortality and incidence, and recently declared its objective to achieve malaria elimination in low . Box: 1176, Addis Ababa, Ethiopia, Mekonnen Adnew Degefu&Woldeamlak Bewket, Met Office Hadley Centre, FitzRoy Road, Exeter, EX1 3PB, UK, You can also search for this author in Tigray the Belg rains are also the most, investigated theme in the Danakil, depression, is. J Met Soc Jpn 81:169177. Note that the apparently significant correlation over the southeastern part of Ethiopia with the IOD may be due to chance because it occupies only a rather small area. Key Message 5: U.S. Precipitation Change. Only Diro et al. 2006; Saji and Yamagata 2003) show that anomalous warming (cooling) over the equatorial East Pacific and Indian Ocean are associated with enhanced (suppressed) rainfall amounts in this wider region. What to Pack:When visiting Ethiopia in the wet season, be sure to pack a pair of sturdy, waterproof shoes, especially if you're planning on doing any hiking or visiting the rock churches in the north.
