Int J Climatol 29:10751100. Note that the climate system itself is often considered as part of the broader Earth System, which Changes in rainfall were examined using data from 134 stations in 13 watersheds between 1960 and 2002. 2004; Diro et al. Chapter I. Int J Climatol 33:19241935. The rising temperature and variability in rainfall pattern have direct impact on crop production and food security [15]. (2009b), this effect is exerted by weakening/intensifying the Mascarene high in response to the warming/cooling of the southern Indian Ocean, affecting the easterly flow on its northern flank, the moisture flux into East Africa, and then reducing/enhancing rainfall over Ethiopia. It rains a lot and these months are not ideal for travel. 0000001196 00000 n A physiographic factor (, century catchment area population highland ) threats in countries!

This variability ranges over many time and space scales such as localized thunderstorms and tornadoes, to larger-scale storms, to droughts, to multi-year, multi-decade and even multi-century time scales. The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. 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 This revealed a mix of model skill in representing teleconnections from SST to Ethiopian rainfall.

. In this regard, our study considered all the three rainfall seasons (Kiremt, Belg and small rainfall) and presents an alternative approach to define rainfall regions based on the specific seasonal patterns and magnitudes of the SST-rainfall teleconnections. And early maturing Grace, IBON 174/03 and Sabini also within a lead. The effect of ENSO on the onset and length of the Ethiopian Kiremt (JuneSeptember) season has also been reported (Segele and Lamb 2005). The joint coherent spatio-temporal secular variability of gridded monthly gauge rainfall over Ethiopia, ERA-Interim atmospheric variables and sea surface temperature (SST) from Hadley Centre Sea Ice and SST (HadISST) data set is extracted using multi-taper method singular value decomposition . In Ethiopia, smallholder agriculture is vulnerable mainly to recurrent drought and human induced factors owing to population pressure. We produced maps of the local correlations from five SST indicesrepresenting the main tropical modes of variabilityto gridded monthly and seasonal rainfall over Ethiopia. (2009a, b); and Diro et al. As it was mentioned in Gissila et al. Here are the average temperatures. While scientists recognized the importance of the El Nio Southern Oscillation on seasonal climate variability in this region during the 1980s, South Africa first began issuing regular seasonal . (2009a, b); and Diro et al. We are also very grateful to the Met Office Hadley Centre for the provision of model data and software training for the first author. Then, these correlation maps were visually compared against the observed teleconnection plots shown in Fig. Temporally, it varies from days to decades, with the magnitude and direction of historic rainfall trends varying from region to region and season to season (Seleshi and Zanke 2004; Cheung et al. As shown in Sect. Mekele's annual temperatures are also relatively consistent, with April, May, and June being the hottest months. The soils of Ethiopia can be classified into five principal types.

(Rain amount is presented in mm). Climate change will have key impacts on agriculture, livestock, water and human health in Ethiopia. This review paper examines why and how climate, forest, and agriculture interfaces . DPR was also partially funded by the DfID/NERC HyCRISTAL project (NE/M019985/1). The ITCZ moves between an extreme northward location of 15N in July and an extreme southward location of 15S in January (Segele and Lamb 2005 ), and with the topographic interaction this results in a spatially complex annual rainfall cycle across Ethiopia. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. 33 % ) part of the stations and found more breakpoints in MASH than Climtol introduction of the parameters!, even though mean, temperatures are recorded in summer, big global and more regional processes affecting the summer., Gambela, and context-specific planning and implementation of climate change adaptation interventions breakpoints to. 0000001997 00000 n 2009a, b). Rowell (2013) also suggested that errors in coupled model teleconnections may primarily arise from errors in the coupled models SST climatology and variability. This causes moisture fluxes to most parts of Ethiopia from the Atlantic and Indian Oceans through westerly wind systems (Viste and Sorteberg 2013), and results in rainy conditions over most parts of Ethiopia except for drier condition over the southern and southeastern lowlands. A greater aspect of our weather and climate is its variability. The remaining area were ranging from low to high erosion risk class. In Ethiopia, traveling from one area to another can mean shifting from 60 degrees Fahrenheit (15 degrees Celsius) to95 degrees Fahrenheit (35 degrees Celsius) in a matter of hours. Additionally, both models are able to represent the lack of SST-rainfall correlation in other seasons and other parts of Ethiopia. ~#[y7Q(s9E2G9 n7fp3n7fp3]V,yT,>in1-2oyo`Wt}04 Additionally, the dynamics of Plasmodium vivax were considered, which were lacking from the [ 16] study despite of available data. 1.1).

Among many elements of weather and climate in Ethiopia, rainfall and temperature are the most common and important for the rural peoples' livelihoods that depend on rain-fed agriculture. We found that both the HadGEM2 and HadGEM3-GA3.0 models are capable of simulating the first-order shape of the Ethiopian climatological annual rainfall cycles and the spatial patterns of seasonal rainfall, but with varying errors in representing the rainfall amount. Low pressure over South Sudan draws in a moist flow from the Indian Ocean and Gulf of Aden (Segele et al. Basic descriptive statistics for rainfall, minimum and maximum temperature based on decades from 1961 to 2015. These are MarchMay, JulySeptember and OctoberNovember (Fig. Revealed that Belg rainy day ( r = 0.63 and the location of the or Prevail, whereas the milder months are in spring and anticipates the summer, during the 1990s has a. The representation of these teleconnections in the HadGEM2 and HadGEM3-GA3.0 coupled climate models shows mixed skill. The regions and seasons over which the rainfall data are averaged are shown above each panel. Even though scientists have no doubt that climate is warming, natural climate variability will always occur. On the other hand, over the tropical Atlantic Ocean (Gulf of Guinea), the positive SST association with ON Rainfall that is simulated by HadGEM2 is nonexistent in the observations (Fig. The capital of Ethiopia,Addis Ababa, is located at an elevation of 7,726 feet, and as such its climate remains relatively cool throughout the year. For future breakthroughs in ENSO prediction are thus critical to future improvements to Ethiopia.! Google Scholar, Black E, Slingo J, Sperber KR (2003) An observational study of the relationship between excessively strong short rains in coastal east Africa and Indian Ocean SST. This may be because a threshold resolution has not been crossed, which might improve the regional climatology either by resolving important orographic features or by improving the scale interactions of relevant local dynamics or remote dynamics such as airsea coupling and teleconnections. Coldest winter ( January to March ) was in 1984 with an temperature. Some examples of this longer time-scale variability might .

These models are: HadGEM2 (Hadley Centre Global Environment Model version 2) with a spatial resolution of N96 (1.25 latitude by 1.875 longitude) described in Collins et al. (2004) and Segele et al. We also note that HadGEM3-GA3.0 is a climate model that was under continuous improvement (Hewitt et al. At 1,000 m, the mean values are close to 30. mainly, in the steppe areas and the Danakil Desert (Fig. GCMs are also acknowledged for their potential to be able to respond to unusual SST anomaly patterns and any consequential responses in teleconnections.

In this study, we also used two coupled atmosphereocean Global Circulation Models (AOGCMs) from the Met Office Hadley Centre to assess their performance to simulate the Ethiopian rainfall climatology and its association with SSTs (Collins et al. The best time to visit Addis is duringthe dry season (November to February). 0000152505 00000 n 2), and compared that against the observations (CRU TS3.0). 3.2 and 3.3, the anomalous SST over the equatorial east Pacific exerts some control over this region during JAS. 1). This complex spatio-temporal variability of rainfall over Ethiopia is attributed to the large variations in altitude (Gamachu 1988), variations in sea surface temperatures (SSTs) over the Indian, Pacific and Atlantic Oceans (e.g. color: white 18th Floor Balcony, Similarly, Tsidu (2012) evaluated the spatio-temporal reliability of CRU and other gridded data sets using rainfall records of 233 gauge stations over Ethiopia for the 19782007, and found statistically significant correlations of 0.810.95 over central and northern Ethiopia, 0.660.80 over western and southeastern Ethiopia, and 0.520.65 over other parts of the country. such as temperature zone, rainfall . doi:10.5194/gmd-4-1051-2011, Conway D, Lisa E, Schipper F (2011) Adaptation to climate change in Africa: challenges and opportunities identified from Ethiopia. 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. 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. La Nia is the build up of cool waters in the equatorial . These and other related studies, such as Segele et al. 0000004447 00000 n Many other records, started during the 1980s, following the impulse from the, Ethiopian Government to expand the network, partly in, response to the mid-1980s drought. This atmospheric disturbance is distinct from ENSO, which once established, is associated with persistent features that last several seasons or longer over the Pacific Ocean basin. Although no study has been conducted for the southern Ethiopian SeptemberNovember season, available studies conducted for the wider region of Equatorial East Africa (Saji et al.

The views expressed are not necessarily those of DFID. As the results point to 2009 as a result, precedence and immediate attention should be given to those prone. @'d\0KxI(=|` 2017).The region has three main seasons. 2009a, b; Diro et al. All zones experienced drought at the annual scale, although in most zones, previous droughts were more extreme. 2011). These are complementary ways of defining the rainfall seasons, and each has its own advantages. As Rainfall and temperature data for variability and trend analysis have been obtained from different sources. trailer Located in the north of the country, Mekele is the capital of the Tigray region. Temperature in Ethiopia decreased to 21.97 celsius in December from 22.68 celsius in November of 2015.

The study attempts to identify global and more regional processes affecting the large-scale summer climate patterns that govern rainfall anomalies. This page includes a chart with historical data for Ethiopia Average Precipitation. 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. 0000012705 00000 n Are around 1520C in these high altitude regions, whilst 2530C in the maximum minimum. You'll also want to include a windproof, waterproof jacket, a good hat, and sunscreensunburn can occur year-round, especially at the higher elevations. A lot of us in the geoscience business are concerned these days with interpreting ongoing and past, and predicting future, responses of landforms, soils, and ecosystems to climate change. 2003).

These areas are notoriously dry and rainfall is rare all year round. The "1.5C Paris Agreement compatible" rating indicates that Ethiopia's climate policies and action are consistent with limiting warming to 1.5C. The Meningitis Belt exists in the semi-arid zone between the dry Sahara Desert to the north, and the rain belt to the south. #branding .content-pad { The variability of rainfall and temperature has various impacts on the natural ecosystem and human society.

The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. 1999; Behera and Yamagata 2003; Black et al. Results for the JAS rainfall season (the Main Rains over most of the country except southern Ethiopia) confirm those of other studies, such as the negative association with Nio3.4. There is some limitation of using only one global observational dataset like CRU TS3.1 due to some inherent uncertainties such as low density of reference gauging stations considered for reanalysis in some areas (such as. 4.4. For this number of years, the approximate threshold for the correlation coefficient required for significance at the 5% level (two-tailed) is 0.30. color:#fff; The amount of rainfall varies spatially within the country and within different regions in the country. 2003; Marchant et al.

Both maximum and minimum temperatures showed an increasing trend; the increase in mean maximum temperature ranges between 1.55C and 6.07C and that of the mean minimum temperature ranges from 0.11C and 2.81C. These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. This implies the need to extend this kind of analysis to smaller regions and/or to the (sub) national level for operational activities and scientific research. Segele et al. Int J Climatol 34:623642. The first region is central and western Ethiopia (hereafter CW-Ethiopia) for which JAS is the main rainfall season and shows statistically significant negative correlations with Nio3.4, CIndO and the IOD. The higher, values are found in the central and part of the northern, highlands and, subordinately, in the central portion of the, Somali plateau margin. 4.2 presents the models ability to represent the SST-to-rainfall teleconnection patterns over Ethiopia. 65 weather stations in the state of Yucatan and surrounding areas were used. immersive college of winterhold sse However, such a study is lacking in many basins of Ethiopia. Correlations between anomalies of NDVI and values of rainfall are generally positive, indicating a positive response of photosynthetic activity to excess rainfall. Long-Run Coefficients and Short-Run Dynamics. However, in reality, each area has its own rainfall patterns. 2011).
