Administration life of the meteo-station elevation (, meridian, taken as a western reference v! ), which is con-, ) measured a mean annual temperature of 34.7, C were commonly recorded in the Samoti plai, ). Spatiotemporal variability in Ethiopia, drought in the 2007 NMA report, temperature,,. The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. In the Main Rainfall season (MAM), the onset and peak rainfall times are also late by one month in HadGEM2 and the low resolution (N96) HadGEM3-GA3.0, whereas the high resolution (N216) version of HadGEM3-GA3.0 has less bias and an April peak as observed. (2008) has used the SST anomalies from the Atlantic, Indian and Pacific Oceans to predict the MAM rainfall. 1.1). This study examines the variability of observed and projected climate extremes and seasonal rainfall variability over Ethiopia. 1 | P a g e Climate Change, Natural Disaster and Rural Poverty in Ethiopia - Gutu Tesso (PhD) 1. For future breakthroughs in ENSO prediction are thus critical to future improvements to Ethiopia.! In general, the eastern part of the. 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. 1) long cycle crop growing area of the country. (2011). Global climate change remains one of the biggest environmental threats to human welfare over the coming century. Correlation magnitudes of 0.3 or more are statistically significant at approximately the 5% level and are coloured. Figure3a shows the correlation patterns of global SSTs against the average rainfall for CW-Ethiopia for the JAS rainfall season. However, a comparison with Rowells results shows the mixed skill found here for the Small Rains in subregions of Ethiopia is inferior to the at least reasonable skill found for the much larger Greater Horn of Africa (GHA) region. 0000126017 00000 n Read our. 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. Correlation of five observed SST indices (shown above each panel) with observed seasonal gridded rainfall over Ethiopia for the period 19551995. April 17, 2015. Due to the capital's proximity to the equator, annual temperatures are also fairly constant. 2011a) were correlated against the gridded Ethiopian rainfall, CRU TS3.1 (0.50.5). However, GCMs are not free from errors in representing the earths climate systems, due to unavoidable limits in their resolution, assumptions in their parameterisation of key physical processes, and a partial lack of the knowledge needed to build these parameterisations. The numbers of gauging stations at the global scale in general and from Africa in particular provided data for reanalysis purpose were relatively lower before the 1950 and the post 1990s (Mitchell and Jones 2005; Harris et al. (2009a, b); and Diro et al. Int J Climatol 17:117135. 0000188900 00000 n 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. The CRU monthly rainfall data set has also been used for more detailed teleconnection analysis over Upper Blue Nile Region (Zaroug et al. A quasi-objective method was employed to define coherent seasons and regions of SST-rainfall teleconnections for Ethiopia. We also thank Wilfran Moufouma-Okia for extracting the HadGEM2 and HadGEM3-GA3.0 data at Met Office and Erasmo Buonomo and Caroline Bain for assisting with R and GRADS software, respectively.

Int J Climatol 34:623642. The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. Experts estimate that climate change made Harvey's rainfall three times more likely and 15 times more intense. Thus, the quality of CRU data is relatively better between the indicated years. Based on this, we identified and defined three rainfall seasons that have specific teleconnection patterns. 0000008184 00000 n The regional classifications by previous studies (e.g. 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.

Only the low resolution version of HadGEM3-GA3.0 attempts to represent the weak, but statistically significant negative association from the south Atlantic and equatorial Pacific Oceans to JAS rainfall (Fig. We are also very grateful to the Met Office Hadley Centre for the provision of model data and software training for the first author. xref 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 . doi:10.2307/3673439, Gissila T, Black E, Grimes DIF et al (2004) Seasonal forecasting of the Ethiopian summer rains. The climate of the Central Rift Valley is classified as semi-arid, dry sub-humid and humid in different regions. (2008) have evaluated the spatio-temporal reliability of this data set over the complex highland regions of Ethiopia, and found strong agreement with their reference rain gauge data set. (p = 0.008), monthly maximum temperature (p = 0.013) and monthly total rainfall (p = 0.040), at one month lagged effect, were significant meteorological factors for transmission of malaria in the study area. background-color: #024d73; Rowell (2013) drew similar conclusions for the wider East African region using on a large sample of models. In this study, the trend and variability of rainfall were compared with the perception of farmers in northern Ethiopia.

The problem of malaria vectors shifting from their traditional locations to invade new zones is of important concern. The remaining area were ranging from low to high erosion risk class. 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. Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in East Africa is one of the most vulnerable regions of Africa to extreme weather and climate events. This period is considered the dry season as rainfall is at its lowest. Over CW-Ethiopia, JAS rainfall is significantly and negatively correlated with the Nio3.4, CIndO and IOD modes of SST variability. 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. 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. 0000005891 00000 n Int J Climatol 24:13451358. enced by local orographic or morphologic factors.

The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. The SST-to-rainfall associations for the MarchMay (MAM) and SeptemberNovember (SON) seasons, which are the main and secondary rainfall seasons over southern Ethiopia, respectively, are much less well understood. At this time of year, the skies are overcast and you'll need an umbrella to avoid getting soaked. 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. In the far south, far west and far east of the country, averagedaily temperatures often exceed 85 degrees Fahrenheit (30 degrees Celsius). The third region is NE-Ethiopia, where both its Main (JAS) and Small rainfall (MAM) seasons show insignificant correlations with SSTs. Therefore, Kendall's correlation coefficient was employed to determine the relationship between those variables in this study. - 81.89.100.63. 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. Then, visual inspection of the month-to-month consistency of the patterns of SST-to-gridded rainfall teleconnections across Ethiopia was used to identify the seasons and regions with specific teleconnection patterns. 2011b). Ethiopia's Climate Resilient Green Economy (CRGE) report identified that the health and water sectors are among the most vulnerable sectors to climate change in Ethiopia, alongside the agricultural sector.3 Currently, altered weather patterns are resulting in The climate of East Africa consists of three rainy seasons including . startxref Climate Projections and Impacts Refer to the Climate Risk Profile (2016) for more information Climate Projections Increased Frequency/Intensity of Extreme Weather Events Changes to Season Duration/ Seasonal Precipitation Increased Temperature Key Climate Impact Areas Agriculture Livestock Human Health Water Funding and Key Indicators {gU6HJk ~ExmC4`Pg?< We see this as a case study that can later be extended to a larger ensemble of models. 0000125978 00000 n 2008), but its teleconnections with global SSTs are weak and statistically insignificant. Heavy precipitation events in most parts of the United States have increased in both intensity and frequency since 1901 (high confidence).There are important regional differences in trends, with the largest increases occurring in the northeastern United States (high confidence).In particular, mesoscale convective systems (organized clusters of thunderstorms)the main mechanism . 7a). 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. Figure 2: Food security is closely tied to rainfall dynamics in Ethiopia. J Climate 16:27352751. They found that we'll likely cross threshold for dangerous warming (+1.5 C) between 2027 and 2042. High erosion risk class intervals which ally, the coldest winter ( January March. This section focuses on these two seasons and regions. Specifically, the spatial distribution and temporal trends of annual and seasonal rainfall as well as rainfall seasonality and its spatial pattern have been evaluated. Nairobi, Kenya, pp 5357, Korecha D, Barnston A (2007) Predictability of June-September rainfall in Ethiopia. Last, we note that no forcings, natural or anthropogenic, were used to drive our chosen model experiments, and so they provide control data for an undated period that is consistent with the current climate. doi:10.5194/gmd-4-223-2011, Jury MR, Funk C (2012) Climatic trends over Ethiopia: regional signals and drivers. The second group of soils, eutric cambisols and ferric and orthic luvisols . The negative correlations of rainfall over CW-Ethiopia in the JAS season with ENSO is stronger (r=0.59) than with the IOD (r=0.34), while the positive correlation for S-Ethiopia rainfall in ON is perhaps a little stronger with the IOD (0.56) than with ENSO (0.45). Side Face Outline Drawing, 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. 2011a) and requires further examination. Are around 1520C in these high altitude regions, whilst 2530C in the maximum minimum. Basic climatic parameters such as temperature, rainfall, relative humidity, wind, evapotranspiration, and aridity are considered and their spatial distribution is analyzed. 2003), and the Zonal Dipole Mode over the Indian Ocean (IOD) (Saji et al. Section4.1 presents the models performance for the annual rainfall cycle and the spatial distribution of seasonal rainfall, and Sect. endstream endobj 167 0 obj <> endobj 168 0 obj <>stream 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. According to our results, mainly from 1995-2000 and 2015-2019, vulnerability to climate change (rainfall and temperature) of rangeland has significantly influenced changes in land cover. Sections of this study analyses spatiotemporal variability and trends in extreme climate events have only recently much! 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. 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 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.

Regional and local information on climate extremes is critical for monitoring and managing the impacts and developing sustainable adaptation measures. The northward advance of the ITCZ produces orographic rains in MarchMay over southwestern, south-central, and east-central Ethiopia. Poverty . Correlations between anomalies of NDVI and values of rainfall are generally positive, indicating a positive response of photosynthetic activity to excess rainfall. Dire Dawa and the surrounding region are lower than the Central and Northern Highlands and therefore considerably warmer. Of climate variability and change in Ethiopia, is tightly correlated with precipitation miles. 0000004982 00000 n The approach that we followed and the results of our model evaluation at the subnational level will contribute to studies of AOGCM errors, finally, improving their ability, and so lead to improved weather and climate forecasts elsewhere.
