To March ) was in 1984 with an average temperature of 18.9 C important cash crops has been. Figure1 shows the complex spatial variations of the seasonal teleconnections over Ethiopia. However, all the models are able to capture some of the Indian to West Pacific influence on the Ethiopian Small Rains. The SSTs indices considered over the Indian Ocean are the central Indian Ocean index (CIndO) average over (55E95E and 25S10N) as described in Rowell (2013), and the Indian Ocean Dipole (IOD) which is the average over (10S10N and 50E70E) minus the average over (10S0 and 90E110E) as described in Saji et al. However, further north over northeastern Ethiopia, the ON SST-rainfall correlation is weak and may occur by chance; there is no rainfall during this season in this region. 2011; Martin et al. Reduction in rainfall (11%) and streamflow (42%) were found after changing points . 156 45 All these studies imply that the SST-to-rainfall teleconnections in Ethiopia are both temporally and spatially complex and not yet well understood. Int J Climatol 21:9731005. The warming trends in the maximum and minimum temperatures for Basona Werana and Efratana Gidim, respectively, are statistically significant at p = .05 and p = .01 levels. 7a).

Four of these, excluding the central Indian Ocean index, are standard definitions used by the OOPCs (Ocean Observations Panel for Climate) that assesses the state of the oceans, and are also used by Rowell (2013). 2365 Unit 210 Exam Simulator, This refers to the natural internal component of atmospheric variability which differs between model simulations could cause some apparent variation in models skill. ~#[y7Q(s9E2G9 n7fp3n7fp3]V,yT,>in1-2oyo`Wt}04 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. Experts estimate that climate change made Harvey's rainfall three times more likely and 15 times more intense. 0000088529 00000 n 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. 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! The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. Ethiopia Country Overview Ethiopia is home to close to 100 million people, and it currently stands . July & August - These are the peak Wet season months.

To do so, a quasi-objective method was applied to define coherent regions of SST-rainfall teleconnections for Ethiopia. Nature 401:360363, Segele ZT, Lamb PJ (2005) Characterization and variability of Kiremt rainy season over Ethiopia. Recent rainfall data for South Eastern Ethiopia show trends of overall declines in rainfall between March and September from 1980 to the present. 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 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. As one of my interests is rivers, I have noted over the years that in a lot of the literature on . The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. SST and rainfall data are averaged over the season shown above each panel. 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. trailer (2008) report that SSTs over the equatorial east Pacific and Indian Oceans are used for operational forecasts by the National Meteorological Agency of Ethiopia.

Its extant relative, Papio anubis, is omnivorous and moves easily on the ground and in trees. Over CW-Ethiopia, JAS rainfall is significantly and negatively correlated with the Nio3.4, CIndO and IOD modes of SST variability. It has also evaluated the ability of the HadGEM2 and HadGEM3-GA3.0 coupled atmosphereocean Global Circulation Models (AOGCMs) to simulate seasonal SST teleconnections to rainfall at the subnational scale, using Ethiopia and these two models as a case study. 0000126017 00000 n At the continental scale (Africa), but using a larger sample of models (44), Rowell (2013) found a similar mix of skill. 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. Ethiopia provides a good example of the influence of climate variability on a developing countrys economy. 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. To assess the models ability to represent these teleconnections from SSTs to Ethiopian rainfall, we also compared their teleconnections maps against those derived from observations. #featurenav a {color: #069} 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. 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. 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. The CRU monthly rainfall data set has also been used for more detailed teleconnection analysis over Upper Blue Nile Region (Zaroug et al. Diverse rainfall and temperature patterns are largely the result of Ethiopia's location in Africa's tropical zone and the country's varied topography. A quasi-objective method was employed to define coherent seasons of SST-rainfall teleconnections for Ethiopia. 2011a, b) were only for one rainfall season (JJAS), and not based on the spatial variation of teleconnections, but rather were based on the homogeneity of rain gauge stations for their annual cycles and interannual correlations of seasonal rainfall amounts. 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. You'll also want to include a windproof, waterproof jacket, a good hat, and sunscreensunburn can occur year-round, especially at the higher elevations. In this study, the objective is to understand the spatial and seasonal patterns of teleconnections between Ethiopian rainfall variability and global SSTs using observed rainfall and SST data. 2). " /> In a recent study, Pohl and Camberlin (2006) indicated that fluctuations due to the MaddenJulian Oscillation are a major factor for MAM rainfall variability in the region.

Mekonnen Adnew Degefu. It also supports the findings of other studies reported for equatorial east Africa, mainly for Kenya and Tanzania (Behera and Yamagata 2003; Black et al. Figure7 shows the performance of HadGEM2 and HadGEM3-GA3.0 for their ability to simulate some of the seasonal and spatial variability of SST-rainfall teleconnections over Ethiopia (see Collins et al. In theory, Ethiopia'srainy seasonbegins in April and ends in September. The Climate Resilient Green Economy (CRGE) strategy must, therefore, make greater efforts to embed young people's livelihoods and wellbeing in the strategy. 2006; Ummenhofer et al. 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 best time to visit Addis is duringthe dry season (November to February). 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. Researchers say it can reduce prediction uncertainties by around 50%. Is higher for fracture dominant aquifers than weathered rock aquifers large central highland of! Afr J Ecol 45:416. Correlation magnitudes of 0.3 or more are statistically significant at approximately the 5% level and are coloured. 2011). 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. 2004; Diro et al. The result showed that the highest change in maximum temperature ranged from 2.93 C to 5.17 C in monthly time scales in the 2080s. (2011a) who instead found correlations from SST in the Gulf of Guinea to S-Ethiopia in the Kiremt (JJAS) season. While the amount of annual rainfall and rainy days decreased in the study Regions in the 2080s. In general, the eastern part of the. (a) AEZ modelling methodology. In Ethiopia, malaria is seasonal and unstable, causing frequent epidemics. 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. Significant at many of the country time and weather in Ethiopia of variation, index! 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. Even in the hottest months (March to May), average highs rarely exceed 77 degrees Fahrenheit (25 degrees Celsius). Throughout the year, temperatures drop quickly once the sun goes down, and frosty mornings are common. Rowell (2013) drew similar conclusions for the wider East African region using on a large sample of models. 0000127516 00000 n This is because we focus here on consistency of rainfall-SSTs correlations for the benefit of seasonal prediction, rather than on climatological rainfall totals. 1). Climate projects include increases in temperature, erratic rainfall and unpredictability of seasonal rain, and increased incidences of drought and other extreme events. hoT>>y;JC&qwy/a)GX't/|. Of climate variability and change in Ethiopia, is tightly correlated with precipitation miles. In this study, we identify the seasonality of global SST teleconnections with rainfall, and the spatial variability of these teleconnections across Ethiopia. In Ethiopia, rainfall and temperature change and variability are expected to have adverse impacts on agriculture and food security [10]. 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. i love you more fights comebacks, Copyright 2007. It usually occurs at altitudes < 2,000 m above sea level. This page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. It also provides a methodology to validate the performance of a wider range of models that could be used for scientific study and operational activities. The occurrence of . Climate change will have key impacts on agriculture, livestock, water and human health in Ethiopia. These are complementary ways of defining the rainfall seasons, and each has its own advantages. The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. endstream endobj 169 0 obj <>stream 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. In addition to this, the high resolution (N216) HadGEM3-GA3.0 model has an early start and excessive rain before the wet season. The threshold for dangerous global warming will likely be crossed between 2027 . 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. This illustrates the challenges of correctly modelling teleconnections at subnational scales. f+`BLfV0[_W~_W~_W~_W~_W~_W~Ya6z1z1z1z1z1z< 4lqyig ? ?[^skxTOS0d};H].;+ + 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 comparative performance of the models is somewhat mixed with neither displaying a consistent character of bias across regions and seasons. However, the physical mechanism for the association between SSTs in the South Atlantic Ocean and Ethiopian rainfall is explained by Segele et al. 2011a). 0000127087 00000 n Coldest winter ( January to March ) was in 1984 with an temperature. Current climate models indicate that rising temperatures will intensify the Earth's water cycle, increasing evaporation. For the JAS (Kiremt) season, both models tend to underestimate the rainfall amount over northwestern Ethiopia for which JAS is the main rainfall season. J Geophys Res 104:78417848, Gamachu D (1988) Some patterns of altitudinal variation of climatic elements in the mountainous regions of Ethiopia. It rains regularly but showers usually don't last long. It was predicted that its climate will warm up 0.7C and 2.3 by the 2020s and between 1.4C and 2.9C by the 2050s. These areas are notoriously dry and rainfall is rare all year round. However, this type of information is not readily available at the necessary spatial resolution. Climate projections for Ethiopia are presented in Box 1. doi:10.1002/joc.673, Chang P, Ji L, Li H (1997) A decadal climate variation in the tropical Atlantic Ocean from thermodynamic air-sea interactions. 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. 3.1), we identified three broader teleconnected rainfall regions (Fig. "Climate & Averages in Addis Ababa." As it was mentioned in Gissila et al. At 1,000 m, the mean values are close to 30. mainly, in the steppe areas and the Danakil Desert (Fig. 2004; Korecha and Barnston 2007; Diro et al. (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. Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. 0000012705 00000 n However, Dinku et al. 2014). 0000006444 00000 n 2011a) and requires further examination. Also, this region is known for its dry climate during this season. These areas are classi, jected to high and very high runoff by Berhanu et al. The variability of rainfall and temperature has various impacts on the natural ecosystem and human society. Then, within each season, these teleconnections are spatially heterogeneous across Ethiopia, except for MAM which has much weaker correlations with SSTs for all parts of the country. The driest months in Ethiopia are typically November and February. It can be seen in Fig. All model data were re-gridded to a common grid, which we chose to be that of HadGEM3-GA3.0-N216. In addition, elevated levels of carbon dioxide have an effect on plant growth. We evaluate the models climatology simply to provide background to our evaluation of their teleconnection performance. Some examples of this longer time-scale variability might . startxref The exact position of the ITCZ changes over the course of the year, oscillating across the (, and high erosion rates would be expected, but the occurrence, of soils with low erodibility, as reported by the USLE, synoptical variations associated with the position of the, ITCZ. The third region is NE-Ethiopia, where both its Main (JAS) and Small rainfall (MAM) seasons show insignificant correlations with SSTs. Correlation magnitudes of 0.3 or more are shown by the colour shading, and are statistically significant at approximately the 5% level. Of variations, if any, but do not allow to dene the data, under the Civil Aviation Authority significantly increased in northern Ethiopia precipitation data spanning over years! Geosci Model Dev 4:10511075. 2009a, b). These are MarchMay (MAM), JulySeptember (JAS) and OctoberNovember (ON). Segele et al. Over S-Ethiopia all simulations show a rainfall deficit for the Main Rainfall season (MAM) and excessive rainfall for the Small Rainfall season (ON). Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of Africa.It shares borders with Eritrea and Djibouti to the north, Somaliland to the northeast, Somalia to the east, Kenya to the south, South Sudan to the west and Sudan to the northwest.Ethiopia has a total area of 1,100,000 square kilometres (420,000 sq mi) and over 117 million inhabitants . (2011); and Martin et al. Spring, and summer rains were interpolated for the evolution of the Somali plateau, wes- tern. 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.

The amount of rainfall varies spatially within the country and within different regions in the country. Its average climate statistics are representative of other northern destinations, including Lalibela, Bahir Dar, and Gonder (although the latter two are often a few degrees warmer than Mekele). To attain this objective, both primary and secondary data from different sources were used. Ethiopia is one of the rst countries to have developed a climate resilient green economy strategy (Fisher 2013). Her work has appeared in Travel + Leisure, USA Today, Michelin Guides, Hemispheres, DuJour, and Forbes. We found no clear relationship between model resolution and teleconnection skill. Timber Framing Slick, 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. PubMedGoogle Scholar. and adaptation options in Ethiopia. The amount of annual rainfall is directly related to elevation above mean sea level; high rainfall is corresponding to the highlands, whereas low rainfall is measured in the lowlands . 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.

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. Global climate change remains one of the biggest environmental threats to human welfare over the coming century. 18th Floor Balcony, J Climate 22:9931013. 1999; Behera and Yamagata 2003; Black et al. The first rule of Ethiopian weather is that it varies greatly according to elevation. 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. Drought-related disasters could be mitigated by warnings if skillful summer rainfall predictions were possible with sufficient lead time. 2008; Jury and Funk 2012; Viste and Sorteberg 2013). This is also a prime time for bird watching. A quasi-objective method was employed to define coherent seasons and regions of SST-rainfall teleconnections for Ethiopia. Int J Climatol 34:623642.

Firstly, a preliminary subdivision . Here are the average temperatures. 0000056870 00000 n This page includes a chart with historical data for Ethiopia Average Temperature. We find there are three distinct rainfall seasons in Ethiopia with their specific SST-to-rainfall teleconnection patterns. Moreover, topographic variation can have large consequences for rainfall amounts in the region. 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. East Africa is one of the most vulnerable regions of Africa to extreme weather and climate events. 0000152101 00000 n Observed and modelled annual cycle of rainfall over a CW-Ethiopia b S-Ethiopia and c NE-Ethiopia.
