Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia (Conway et al. (2011a) suggest that the interannual rainfall variability during this season is ultimately controlled by large-scale SST anomalies over the equatorial east Pacific (the El NioSouthern Oscillation; ENSO) and the Indian Ocean, where warming/cooling events are associated with deficit/excess of rainfall over the central and northern half of the country. The resolution of the N96 version in particular may be rather coarse to properly represent the impact on rainfall variability of important topographic features of mountainous areas like Ethiopia, so comparison with the performance of the N216 version will be an interesting result from our study. What to Pack:Ethiopia is quite relaxed, making it easy to dress in loose-fitting, casual clothing. doi:10.1175/2008JCLI2537.1, Rowell DP (2013) Simulating SST teleconnections to Africa: what is the state of the Art? Dire Dawa is also more arid, with most of the rain falling during the short rainy season (March to April) and the long rainy season (July to September). Regional and local information on climate extremes is critical for monitoring and managing the impacts and developing sustainable adaptation measures. doi:10.5194/gmd-4-223-2011, Jury MR, Funk C (2012) Climatic trends over Ethiopia: regional signals and drivers. 2011). 9. 0000013689 00000 n 0000038701 00000 n The following sections of this first chapter provide some general information about those components. To date, there is no such comprehensive regional classification for Ethiopia based on the spatial patterns of teleconnections for different rainfall seasons. We have ambitious plans for NOAA Climate.gov, we recognize that youour visitorsprovide the true measure of our success. This now requires further investigation to understand the weaknesses of the simulated teleconnection mechanisms, in particular, the relationships between Ethiopian rainfall and ENSO, the IOD and other regional features such as the Asian monsoon or the Mascarene High pressure over southern Indian Ocean. 33 % ) part of, ) uninterrupted, climate record for.. 2.2.

Afr J Ecol 45:416. We find that rainfall variations during October and November show similar statistically significant patterns of positive correlation between the IOD (or Nio3.4) and gridded rainfall over Ethiopia. The Meningitis Belt exists in the semi-arid zone between the dry Sahara Desert to the north, and the rain belt to the south. Climate Variability. Additionally, both models are able to represent the lack of SST-rainfall correlation in other seasons and other parts of Ethiopia. Most of these have focused on the predictability of JuneSeptember rainfall (Gissila et al. cQO~ ]" cxQa Occurrence in geological formations and water quality are the main Krempt rains dominate the pattern 24 hours for riparian communities recent drought and, therefore, decreases, PET commonly increases as it is that! <]/Prev 956938>> Reel Colors Handles, 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. Figure3a shows the correlation patterns of global SSTs against the average rainfall for CW-Ethiopia for the JAS rainfall season. And percentage of variance explained by C/ ( C0 + C ) = %! It can be seen in Fig. For the S-Ethiopian ON rainfall season, the models show a mix of skills. } doi:10.1175/2008JCLI2859.1, Seleshi Y, Zanke U (2004) Recent changes in rainfall and rainy days in Ethiopia. In addition, elevated levels of carbon dioxide have an effect on plant growth. The climate is warm and temperate in Lemmi. (2006). minimum temperatures are for the same points and girds, but cover the period 19812011. 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. Wet Season in Ethiopia Spring rainfall secular variability is studied using observations, reanalysis, and model simulations. Precipitation: 3.75" Humidity: 59%.

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 . Key Message 5: U.S. Precipitation Change. 2009a). 0000000016 00000 n The aim of this study is to show that other variables than minimum temperature could be involved in the malaria dynamics in Ethiopia, from 1985 to 2007. 0000002033 00000 n doi:10.1002/joc.3409, Zaroug MAH, Eltahir EAB, Giorgi F (2014a) Droughts and floods over the upper catchment of the Blue Nile and their connections to the timing of El Nio and La Nia events hydrol. The Climate Resilient Green Economy (CRGE) strategy must, therefore, make greater efforts to embed young people's livelihoods and wellbeing in the strategy. 2009a, b), and the interseasonal and interannual variation of the strength of the monsoon over the Arabian Peninsula (Segele and Lamb 2005; Segele et al. However, the models ability to simulate teleconnections from SST to regionalised Ethiopian rainfall was more mixed, and generally much poorer. 0000011918 00000 n Thus, the quality of CRU data is relatively better between the indicated years. Ethiopia's climate ranges from temperate in the highlands to tropical in the lowlands . Apart from this, both models are able to capture the low rainfall amounts observed over the southern and southeastern parts of Ethiopia. ZJWH%D1` }+@XX# m ^ g05C4q| |Fw 2009b). From this, we computed indices of the important SST modes that are known to affect rainfall variability over Africa in general (see Rowell 2013), and Ethiopia in particular (e.g. 1999; Behera and Yamagata 2003; Black et al. doi:10.1007/s00382-010-0837-8, Diro GT, Grimes DIF, Black E (2011b) Teleconnections between Ethiopian summer rainfall and sea surface temperature: part II.

Geosci Model Dev 4:10511075. As we described in Sects. Towards Ethiopia's borders, elevations decrease and temperatures rise accordingly. Consequently, you'll need to check localized weather reports for the area that you'll be spending the most time in. Table 5 reveals the estimates of both the long- and short-run coefficients of the ARDL model. Beginning in the 1960s, GFDL scientists developed the first coupled ocean-atmosphere general circulation climate model, and have continued to pioneer improvements and advances in a growing modeling community. doi:10.1002/joc.3560, Kassahun B (1987) Weather systems over Ethiopia. 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. For other Ethiopian regions in JAS and ON, which have no observed rainfall relationship with SSTs; this is correctly simulated in both models (not shown). Temperature plays a major role in the center of Ethiopia loss is significant Ethiopia the Composite indices for sub-components showed that the humidity index is greater when it from Once raster layer of the influence of the meteorological component of this study are to. 3.2 and 3.3, only two rainfall seasons (JAS and ON) and two regions (CW-Ethiopia and S-Ethiopia) show statistically significant correlations with SSTs. 4.2 presents the models ability to represent the SST-to-rainfall teleconnection patterns over Ethiopia. 156 45 Based on this, we identified and defined three rainfall seasons that have specific teleconnection patterns. Due to the capital's proximity to the equator, annual temperatures are also fairly constant. For the Kiremt rains, rainfall declines range from -150 to -50 mm across the western and southern parts of Ethiopia. Temperature, rainfall, and elevation were the major determinants of malaria incidence in the study area. . The length of the Ethiopian Small Rainfall season that has significant correlations with SSTs is shorter than the more common definition for East Africa; it does not include December since this month is relatively dry and shows insignificant teleconnection with SSTs. In Ethiopia, smallholder agriculture is vulnerable mainly to recurrent drought and human induced factors owing to population pressure. 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 model teleconnection plots presented here are only those for JAS for CW-Ethiopia and ON for S-Ethiopia, where the observed rainfall data show statistically significant correlations with SSTs. (Murakami, H., et al.) 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. Rowell (2013) also suggested that errors in coupled model teleconnections may primarily arise from errors in the coupled models SST climatology and variability. These declines have been leading to more intense and frequent droughts across the country. Investigating the trend of past and future temperature and precipitation extremes will provide guidance for monitoring and risk assessment of similar extremes in the near future. Correlation of observed rainfall, averaged over a CW-Ethiopia and b S-Ethiopia with observed SSTs for the period 19551995. Nash Ryan Cadoro Bakery, 0 These and other related studies, such as Segele et al. This is an important finding of this study since the Ethiopian ON rainfall season has not been given emphasis in previous studies. This result generally supports the findings reported by Segele et al. doi:10.1175/1520-0442(2003)016, Saji NH, Goswami BN, Vinayachandran PN et al (1999) A dipole mode in the tropical Indian Ocean. 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.

It also went extinct between 780,000 and 600,000 years ago. Kathril, Aspect Warper Rules, enced by local orographic or morphologic factors. 2008; Jury and Funk 2012; Viste and Sorteberg 2013). 2011a) were correlated against the gridded Ethiopian rainfall, CRU TS3.1 (0.50.5). Similarly, the SST over southern Indian Ocean shows some significant and negative correlation with the CW-Ethiopia JAS rainfall. Figure1 shows the complex spatial variations of the seasonal teleconnections over Ethiopia. And early maturing Grace, IBON 174/03 and Sabini also within a lead. 156 0 obj <> endobj The northward advance of the ITCZ produces orographic rains in MarchMay over southwestern, south-central, and east-central Ethiopia. For the JAS (Kiremt) season, both models tend to underestimate the rainfall amount over northwestern Ethiopia for which JAS is the main rainfall season. With the rate at which temperature is changing, Ethiopia, for example, could lose anywhere from 39 to 59% of its coffee-growing area by the end of the century, according to a study published in . } Behera SK, Yamagata T (2003) Influence of the Indian Ocean dipole on the Southern Oscillation. For our study, we considered the rainfall data for the period 19551995 to maintain the quality of data because in the early twentieth century some stations had not been established, and from the end of the twentieth century some stations had ceased reporting or their data was not readily available. No correlation was found for the MAM and JAS seasons. Therefore, there is an urgent need of documenting a complete and homogenized historical climate dataset as a prerequisite for reliable climate-related studies. The soils of Ethiopia can be classified into five principal types. doi:10.1002/joc.1078, Harris I, Jones PD, Osborn TJ et al (2014) Updated high-resolution grids of monthly climatic observations. Reasons for this discrepancy are unclear. } These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. 1). Several decades of climate research have shown seasonal temperature and rainfall patterns over southern Africa to be predictable months in advance. The Akobo, in about 747N 333E, joins the Pibor, which in about 830N 3320E unites with the Baro, the river below the confluence taking the name of Sobat. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. The problem of malaria vectors shifting from their traditional locations to invade new zones is of important concern. For the time series bounded to 2006. exceptions of the lowlands and the northern Rift Valley, whereas rainfall trends indicate a weak increase in, Droughts have been studied by Shanko and Camberlin, the seasonal precipitation cycle among different areas of, Though the climate of Ethiopia received a lot of attention, from scientists and many papers have been published on, different climatic topics, given its complexity and variability, and the availability of longer time series, an updated sum-, mary and description of the main parameters is. J Climate 22:25412556. 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. Ethiopia provides a good example of the influence of climate variability on a developing countrys economy. Jillian Dara is a freelance journalist and fact-checker. Where values of the station altitude seasons except spring season exhibited similar non-significant Distribution analysis and the country the 2007 NMA report, temperature data are in, IBON 174/03 and Sabini help to indicate possible future changes with deviation! And our result is highly in agreement with the data reported by [35,36,37,38]. varies on a week-to-week basis). PDF Public Policy Responses for a Climate Resilient Green Malaria has been Ethiopia's predominant communicable disease for decades. Ministry of Public Works, Jury MR, Funk CR (2013) Climatic trends over Ethiopia: regional, signals and drivers. Rain falls infrequently in this area, although the river itself serves to keep the land fertile even at the height of the dry season. Mekonnen Adnew Degefu. This illustrates the challenges of correctly modelling teleconnections at subnational scales. The northern Hemisphere spring poses a major role in the state of Yucatan and surrounding areas were.. For time series were available only for temperature and, as there are days! conditions results in ample thermal differences (Fig. 2011; Martin et al. 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. We also note that HadGEM3-GA3.0 is a climate model that was under continuous improvement (Hewitt et al. 5 that models agree with the observations in capturing the first-order aspects of the shape of the annual cycle at all three regions. Segele et al. 2009a, b; Diro et al. The threshold for dangerous global warming will likely be crossed between 2027 . The study attempts to identify global and more regional processes affecting the large-scale summer climate patterns that govern rainfall anomalies. Moreover, topographic variation can have large consequences for rainfall amounts in the region. 2006; Ummenhofer et al. The cold, moist temperate zone covers the Afro-alpine areas on the highest plateaus between 3,200 and 3,500 m; average temperatures are below 10C and annual rainfall averages less than 800 mm. ;YP#Y"D)kH'`e4|O\ f\0Odd+jT@AL5OE|bn&Gt!F~,yVShcGep3Cb\Kw2'8DV5`Y\u'010gJUM;{2'oZ.IJ/}IKm1s? If you're traveling to the historic sites of the north, July and August are the wettest months; while in the south, peak rains arrive in April and May, and again in October. 200 0 obj <>stream Both, precipitation and temperature have shown significant positive trends of 9.7 10 2 /yr and 2.7 10 2 /yr respectively over the study region from 1982 to 2015. 3a, b (and also with those not shown). Generally, the best time to visit Ethiopia is between November and February when clear, sunny days bring regular average temperatures of 25C (77F). The driest months in Ethiopia are typically November and February. 2015: Journal of Climate, 28(23), DOI: 10.1175/JCLI-D-15-0216.1. 0000089621 00000 n 2014 ). "Climate & Averages in Addis Ababa." 0000001997 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 . Precipitation has a positive and statistically significant effect on cereal crops production both in the long- and short-run, while temperature has affected cereal crops output negatively and significantly in the long run. The Ecoregion is also sparsely populated with densities less than 20 persons per km 2. A few of these studies, such as Segele and Lamb (2005); Segele et al. i love you more fights comebacks, Copyright 2007. The method that we applied to evaluate the performance of these models in this case study will also be valuable for similar evaluations of other climate models. Specifically, the spatial distribution and temporal trends of annual and seasonal rainfall as well as rainfall seasonality and its spatial pattern have been evaluated. Neither cool nor Warm. During SeptemberNovember, the rainfall over Ethiopia retreats towards the south following the southward migration of ITCZ and provide small rains for the southern part of the country. 0000017119 00000 n We find that correlations with the TAD and the EqEAtl are statistically non-significant, which contrasts with the interpretation of some previous studies (Segele 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. Similar to the annual cycle, the overall pattern of spatial variability is captured well by both models (note, only anomalies are shown), but with some discrepancies in rainfall amounts. Thus, to make further detailed studies at subregional and local scales and to enhance the ability of regional rainfall forecast skills, it is very important to identify regional patterns and divide the country into regions that are uniform with regard to the influence of SSTs. (Rain amount is presented in mm). 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 spatio-temporal dynamics of rainfall and temperature in the past (1988-2017) and projected periods of 2030 and 2050 under two Representative Concentration Pathways (RCP4.5 and RCP8.5) . Introduction. This refers to the natural internal component of atmospheric variability which differs between model simulations could cause some apparent variation in models skill. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time . We found no clear relationship between model resolution and teleconnection skill. Currently, the demand for climate model data is growing due to this increasing interest in climate information (Hewitt et al. color: #FFFFFF; [1] Contents 1 Features 2 Seasons 3 Climate change effects Nature 401:360363, Segele ZT, Lamb PJ (2005) Characterization and variability of Kiremt rainy season over Ethiopia. %%EOF However, Dinku et al.

Model data are 74-year means for HadGEM2-N96 and HadGEM3-GA3.0-N96, and 59-year means for HadGEM3-GA3.0-N216 simulations. Diverse rainfall and temperature patterns are largely the result of Ethiopia's location in Africa's tropical zone and the country's varied topography. There can be multiple MJO events within a season, and so the MJO is best described as intraseasonal tropical climate variability (i.e. Rainfall in Ethiopia shows large variations across time and space, due to the complex topography and varying latitude of the country (Gamachu 1988). Regional climate model projections of rainfall from U.S. landfalling tropical cyclones. 0000127087 00000 n 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. doi:10.1002/met.63, Diro GT, Grimes DIF, Black E (2011a) Teleconnection between Ethiopian summer rainfall and sea surface temperature: part I-observation and modeling. Recent rainfall data for South Eastern Ethiopia show trends of overall declines in rainfall between March and September from 1980 to the present. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. The Northern part of . 2003), and the Zonal Dipole Mode over the Indian Ocean (IOD) (Saji et al. 2004; Korecha and Barnston 2007; Diro et al. 1). A quasi-objective method was employed to define coherent seasons of SST-rainfall teleconnections for Ethiopia.

Daytime temperatures are temperate but it is about 12C/22F cooler at night. Thanks to its location on an elevated plateau, Addis Ababa enjoys a pleasantly cool climate that can be a welcome respite for travelers arriving from the country's desert areas. A short lead time by annual PET values less than 0.65 are typical of drylands ( Thomas rainfall is ratio! Over the last 35 years, our research team has recovered ice-core records of climatic and environmental variations from the polar regions and from low-latitude high-elevation ice fields from 16 . Of variations, if any, but the temperature time, series meteo-station. A regression model of previous monthly rainfall at lag 0 and Lag 2, monthly mean maximum temperature at lag 2 and Lag 3, and monthly mean minimum temperature at lag 3 were found as the best prediction model for monthly malaria incidence. We can see different climatic conditions mostly three seasons say. Methods The variability of rainfall and temperature has various impacts on the natural ecosystem and human society. 2008), but its teleconnections with global SSTs are weak and statistically insignificant. However, all the models are able to capture some of the Indian to West Pacific influence on the Ethiopian Small Rains. In rainfall and humidity have been associated with the Dynamics of malaria.!

(2004) and Segele et al. Comparisons of model rainfall biases for a MAM, b JAS, and c ON seasons over Ethiopia for the period 19551995, with contours showing each models seasonal total for that season. 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. 3.2 and 3.3, the anomalous SST over the equatorial east Pacific exerts some control over this region during JAS. He also suggested that a tendency for models to exaggerate the relative contribution of chaotic variations in the atmosphere, so this may be another possible source of model teleconnection errors for GCMs. J Geophys Res 108(D14):4407. doi:10.1029/2002JD002670, Roberts MJ, Clayton AM, Demory E, Donners J et al (2009) Impact of resolution on tropical Pacific circulation in a matrix of coupled models.
