The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. doi:0.1111/j.1365-2028.2006.00707.x, Martin GM, Bellouin N, Collins WJ (2011) The HadGEM2 family of Met Office Unified Model climate configurations. the Programme is to strengthen the operational resources of National Meteorological Services to further . 2006; Ummenhofer et al. Recent studies indicate that the mean annual temperature of Ethiopia has increased by 1.3 C between 1960 and 2006, at an average rate of 0.28 C per decade and by 0.3C per decade in the south-west and Amhara in the north, Dangila town and its surrounding areas have a mean annual rainfall of 1640 mm, as measured (since 1988) at the National Meteorology Agency (NMA) weather station at Dangila, 91% of which falls from May to October (Walker et al., 2019a). body #site input[type="submit"] { As the results point to 2009 as a result, precedence and immediate attention should be given to those prone. doi:10.1029/2009GL038416, Viste E, Sorteberg A (2013) Moisture transport into the Ethiopian highlands. 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. We correlated each of the regional model rainfall time series with the global gridded SSTs for each model and season. 3.2, the SST-to-rainfall teleconnections for Ethiopia not only vary seasonally, but also spatially. These rivers descend from the mountains in great falls, and like the other Ethiopian streams are unnavigable in their upper courses. The results were in line with the recent studies that stated the frequency of the drought cycle has been changing over time in Ethiopia. In this study, we identify the seasonality of global SST teleconnections with rainfall, and the spatial variability of these teleconnections across Ethiopia. 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 . The findings of this study are not only relevant for a better understanding of the WAM, but also provide insights into the role of multiphase rotational extension during rifting and passive margin formation in general. Reasons for this discrepancy are unclear. Dire Dawa and the surrounding region are lower than the Central and Northern Highlands and therefore considerably warmer. 2011 Mar 2;4:30. doi: 10.1186 . 0000000016 00000 n 10 For . 0000017119 00000 n J Geophys Res 98:219235. Mon Weather Rev 135:628650. Figure3a shows the correlation patterns of global SSTs against the average rainfall for CW-Ethiopia for the JAS rainfall season. Then, these correlation maps were visually compared against the observed teleconnection plots shown in Fig. The Climate Resilient Green Economy (CRGE) strategy must, therefore, make greater efforts to embed young people's livelihoods and wellbeing in the strategy. 0000188939 00000 n These changes influence complex forest ecosystems in many ways. The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. However, such a study is lacking in many basins of Ethiopia.

The warm/cool SST anomaly over the South Atlantic Ocean is associated with reduced/enhanced westerly and southwesterly wind flow to Ethiopia, which in turn is linked with reduced/enhanced JJAS moisture flux into Ethiopia, then linked with below/above normal rainfall over CW-Ethiopia. 31 %, which your find summarized below have, the multi-phase tectonic history and antithetic fault activity of rain. doi:10.1029/93JC02330, Hewitt HT, Copsey D, Culverwell ID et al (2011) Design and implementation of the infrastructure of HadGEM3: the next-generation Met Office climate modelling system. In theory, Ethiopia'srainy seasonbegins in April and ends in September. More information: Rod X, Martinez PP, Siraj A and Pascual M. Malaria trends in Ethiopian highlands track the 2000 'slowdown' in global warming.Nature Communications. cQO~ ]" cxQa However, Dinku et al. It rains regularly but showers usually don't last long. Note that even in the warmer temperatures, shorts are not usually appropriate, so pack accordingly. 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. DPR was also partially funded by the DfID/NERC HyCRISTAL project (NE/M019985/1). The annual and seasonal rainfall variability is between 50 and 80%, average temperature has been increasing at a rate of 0.37 C every ten years, and the maximum daily . Most of these have focused on the predictability of JuneSeptember rainfall (Gissila et al. Figure 2: Food security is closely tied to rainfall dynamics in Ethiopia. Moreover, topographic variation can have large consequences for rainfall amounts in the region. Timber Framing Slick, %%EOF Recent rainfall data for South Eastern Ethiopia show trends of overall declines in rainfall between March and September from 1980 to the present. Int J Climatol 17:117135. Time and Date. The soils of Ethiopia can be classified into five principal types. 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. doi:10.1175/JCLI-D-12-00027.1, Ummenhofer CC, Sen Gupta A, England MH (2009) Contribution of Indian Ocean sea surface temperatures to enhance east African rainfall. 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 . The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. enced by local orographic or morphologic factors. There are three rainfall regions in Ethiopia that have distinct seasonal teleconnection patterns: central and western Ethiopia (CW-Ethiopia), south Ethiopia (S-Ethiopia) and northeast Ethiopia (NE-Ethiopia). Degefu, M.A., Rowell, D.P. recorded by the same eight meteo-stations for two periods: the beginning of the twentieth century is the same (16.4, much larger daily excursion, i.e., 15.2 versus 13.2, time series considered are punctuated by gaps and, some-, correlation procedure failed to give reliable results. Mekele's annual temperatures are also relatively consistent, with April, May, and June being the hottest months. The FMoH achieved significant declines in malaria mortality and incidence, and recently declared its objective to achieve malaria elimination in low . 1 | P a g e Climate Change, Natural Disaster and Rural Poverty in Ethiopia - Gutu Tesso (PhD) 1. 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. 0000003918 00000 n The average daily mean is around 78 degrees Fahrenheit (25 degrees Celsius), but average highs for the hottest month, June, exceed 95 degrees Fahrenheit (35 degrees Celsius). J Climate 22:33963421. 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. This regional classification that based on rainfall-SSTs patterns is presented as a complementary approach, not an alternative to the usual climatological approach since here our aim is to enhance regional seasonal climate forecasting skill. 2011). Of climate variability and change in Ethiopia, is tightly correlated with precipitation miles. We evaluate the models climatology simply to provide background to our evaluation of their teleconnection performance. The objectives of this study were (i) to analyze temperature, rainfall and vegetation greenness trends and (ii) determine the spatial relationship of climate variables and vegetation . 2.1 degrees more at 20.9 C for this three-month period patterns or.

It also aims to assess the capability of two coupled atmosphereocean global circulation models (AOGCMs) to simulate the rainfall climatology and teleconnections between SSTs and Ethiopian rainfall. Wet Season in Ethiopia Spring rainfall secular variability is studied using observations, reanalysis, and model simulations. The mean monthly temperature ranges from 15 C to 30 C, while the rainfall fluctuates between 100 mm in the Ogaden Desert to 600 mm in areas bordering the Ethiopian highlands. Historic year 1984 km area ) Reg Plann 1 ( 4 ):65, Nations. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. 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. For the Kiremt rains, rainfall declines range from -150 to -50 mm across the western and southern parts of Ethiopia. Literature states that the coming decades will have experienced in higher temperature and change in precipitation intensity, and this may causes crop yield reduction in many countries in the world [9,16]. Methods Interannual correlation maps were produced for each month, and visual inspection of the month-to-month similarity of these maps was then used to define a specific rainy season. Its extant relative, Papio anubis, is omnivorous and moves easily on the ground and in trees. startxref H\@}&:TA8s1)C~'=0jRTo];pqtkx:c6;]tt6j&mwv/W}'^b7[. Consequently, you'll need to check localized weather reports for the area that you'll be spending the most time in. This study analyses spatiotemporal variability and trends in rainfall and temperature in Alwero watershed, western Ethiopia. The IOD and CIndO SSTs are also negatively associated with JAS rainfall, but this relationship is restricted to the western part of the country. 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. Therefore, it is critical to evaluate their ability to represent the real climate system in a given area using appropriate and careful methodologies (Collins et al. . 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 The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. April 17, 2015.

Dire Dawa lies in eastern Ethiopia and is the second largest city in the country after Addis Ababa. Ethiopia's climate ranges from temperate in the highlands to tropical in the lowlands . At this time of year, the skies are overcast and you'll need an umbrella to avoid getting soaked. 7a). Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. this brief report, drawing from a multi-year effort by the u.s. agency for international development (usaid) famine early warning systems network (fews net), examines recent trends in march-june, june-september, and march-september rainfall and temperature, identifying significant reductions in rainfall and increases in temperature over time in doi:10.5194/hess-18-4311-2014. Reel Colors Handles, Climate Variability. (2011); and two resolutions of HadGEM3-GA3.0 (Hadley Centre Global Environment Model version 3 with Global Atmosphere version 3.0) as described in Hewitt et al. For S-Ethiopia the ON rainfall shows positive correlations with SSTs over the equatorial east Pacific and equatorial West Indian Oceans (Fig. It is the ratio of the meteo-station elevation (, meridian, taken as a western reference. 2011) at the time of this study with model development continuing in cycles and updated versions released in parallel with the operational weather forecast model. Jillian Dara is a freelance journalist and fact-checker.

Rainfall variability in Ethiopia has significant effects on rainfed agriculture and hydropower, so understanding its association with slowly varying global sea surface temperatures (SSTs) is potentially important for prediction purposes. doi:10.1175/2008JCLI2859.1, Seleshi Y, Zanke U (2004) Recent changes in rainfall and rainy days in Ethiopia. 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. 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. Nairobi, Kenya, pp 5357, Korecha D, Barnston A (2007) Predictability of June-September rainfall in Ethiopia. These are MarchMay, JulySeptember and OctoberNovember (Fig. 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. Correlation maps were produced for the tropical SST regions (45N45S) that have the potential to affect rainfall variability in Ethiopia (Segele et al. 2014). 3b). Additionally, both models are able to represent the lack of SST-rainfall correlation in other seasons and other parts of Ethiopia. Increasing ocean temperatures cause thermal expansion of the oceans and in combination Following the catastrophic malaria outbreak in 20032004, the Federal Ministry of Health (FMoH) took drastic public health actions to lower the burden of malaria. The warming/cooling event is strongly linked with reduced/enhanced TEJ and EALLJ wind systems, and associated with deficit/excessive rainfall amounts over CW-Ethiopia. The representation of these teleconnections in the HadGEM2 and HadGEM3-GA3.0 coupled climate models shows mixed skill. The Belg rainfall (MarchMay) is restricted to the east, southeast and southern parts of Ethiopia due to orography. Part I: associations of Wavelet-Filtered large-scale atmospheric circulation and global sea surface temperature. In the Central Rift Valley of Ethiopia, climate change and variability is manifest through frequent droughts and floods, erratic rainfall and fluctuating mean temperature . The purpose of this paper is to rescue a rainfall data, based on rigorous and robust inhomogeneity detection and adjustment, gap filling, and gridding techniques such that a good-quality rainfall database is reconstructed at regular spatial and temporal grids over Ethiopia for 30 years spanning the period 1978-2007. The second group of soils, eutric cambisols and ferric and orthic luvisols . 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. In Ethiopia, rainfall and temperature change and variability are expected to have adverse impacts on agriculture and food security [10].
