Finally, the detected inhomogeneity causes a significant error to the region, Dessie, Combolcha Mekele! Geosci Model Dev 4:10511075. 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 . 156 45 Climate change will have key impacts on agriculture, livestock, water and human health in Ethiopia. Rate is 5.8, estimated to be able to cope with the changing climate have been associated the. We defined rainfall seasons based on the month-to-month consistency of the patterns of SST-to-rainfall teleconnections across Ethiopia. For the S-Ethiopian ON rainfall season, the models show a mix of skills. GCMs are also acknowledged for their potential to be able to respond to unusual SST anomaly patterns and any consequential responses in teleconnections. 2011; Hewitt et al. 4. Most of these have focused on the predictability of JuneSeptember rainfall (Gissila et al. 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. (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. 0000152505 00000 n 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. 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. The skewness of rainfall, minimum, and maximum temperature respectively are 1.39, 0.73, and 0.06. 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. These areas are classi, jected to high and very high runoff by Berhanu et al.

Figure6ac shows the performance of these models in representing the spatial patterns of seasonal rainfall over Ethiopia. The third region is NE-Ethiopia, where both its Main (JAS) and Small rainfall (MAM) seasons show insignificant correlations with SSTs. Conf. Towards Ethiopia's borders, elevations decrease and temperatures rise accordingly. A Strong relationship between NDVI and rainfall was reported by Martiny et al. 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. %%EOF As a result, rural people do not have alternative outlet for the increasing unemployed and underemployed workforce to relieve the ongoing pressure on land (Kebede and Zewdu, 2014). In late 2012, we began transitioning to an operational status, which we completed in early 2013. 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. 0000005621 00000 n Kathril, Aspect Warper Rules, Figure1 shows the complex spatial variations of the seasonal teleconnections over Ethiopia. 0000004598 00000 n 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. 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. 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. Dire Dawa lies in eastern Ethiopia and is the second largest city in the country after Addis Ababa. Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia (Conway et al. 0000125978 00000 n 2.2. The Northern part of . Observed SSTs from the Hadley Centre Global Sea Ice and Sea Surface Temperature (HadISST1.1) data set at 11 resolution, described by Rayner et al. "Climate & Averages in Addis Ababa." 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. (2009a, b); and Diro et al. (2009a, b); and Diro et al. 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. The first type is composed of euritic nitosols and andosols and is found on portions of the Western and Eastern highlands. Both fail to simulate the positive correlation from the Equatorial east Pacific to S-Ethiopian ON rainfall variability, although perhaps HadGEM3-GA3.0 (N96) very weakly captures it. 2009b). To attain this objective, both primary and secondary data from different sources were used. - 81.89.100.63. Daytime temperatures are temperate but it is about 12C/22F cooler at night. most important factors. These rivers descend from the mountains in great falls, and like the other Ethiopian streams are unnavigable in their upper courses. #featurenav a {color: #069} 1) long cycle crop growing area of the country. The research was aimed at addressing the national and local issues of climate change and was done by analyzing time series temperature and rainfall trends in the highlands of Ethiopia and LTSB in particular. The warm to cool, semi-humid zone: covers the mild highlands between 1,500 and 2,500 meters. 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. Generally, the best time to visit Ethiopia is between November and February when clear, sunny days bring regular average temperatures of 25C (77F). 2011). The occurrence of . 2011a). More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century. These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. Climate Variability.

Observed and modelled annual cycle of rainfall over a CW-Ethiopia b S-Ethiopia and c NE-Ethiopia. This page includes a chart with historical data for Ethiopia Average Precipitation. 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. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. 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. However, further studies should be conducted to understand the global and regional drivers of rainfall variability for the seasons and regions that have poor associations with global SSTs, including use of initialized predictions. 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. ), which is con-, ) measured a mean annual temperature of 34.7, C were commonly recorded in the Samoti plai, ).

In this regard, global circulation models (GCMs) are critical tools that aid our understanding of the complex global atmospheric circulation and also enhance weather and climate prediction skill (Collins et al. 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.

PDF Public Policy Responses for a Climate Resilient Green Malaria has been Ethiopia's predominant communicable disease for decades. J Climate 22:33963421. To do so, five SSTs time series (TAD, EqEAtl, CIndO, IOD and Nio3.4) that are known to affect the Ethiopian rainfall (Gissila et al. 0000089208 00000 n Roberts et al. The findings of our study, therefore, support this view. The left-hand column shows the observed seasonal totals (CRU3.0) for reference. The effect exerted by the TAD, EqEAtl and CIndO during this season is also very weak and likely statistically insignificant for both southern and northeast Ethiopia. This result generally supports the findings reported by Segele et al. Over CW-Ethiopia, JAS rainfall is significantly and negatively correlated with the Nio3.4, CIndO and IOD modes of SST variability. For the JAS (Kiremt) season, both models tend to underestimate the rainfall amount over northwestern Ethiopia for which JAS is the main rainfall season. 2004; Korecha and Barnston 2007; Diro et al. The results were in line with the recent studies that stated the frequency of the drought cycle has been changing over time in Ethiopia. Similarly, both models are able to simulate the nonexistent Ethiopian MAM rainfall teleconnections with SSTs in all the three subregions. 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 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. Compared with HadGEM2, the HadGEM3-GA3.0 model greatly overestimates the rainfall over two distinct regions aligned northsouth cover much of southern and eastern Ethiopia. It is the main rainfall season in southern Ethiopia and the secondary rainfall season over the central and northeastern Ethiopia (Diro et al.

It also went extinct between 780,000 and 600,000 years ago. Rain falls infrequently in this area, although the river itself serves to keep the land fertile even at the height of the dry season. 2009a). 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]. Low pressure over South Sudan draws in a moist flow from the Indian Ocean and Gulf of Aden (Segele et al. 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. The soils of Ethiopia can be classified into five principal types. 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 observed strong negative rainfall teleconnections with the equatorial east Pacific and southern Indian Oceans SSTs are not captured by either model. 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). Thus, the quality of CRU data is relatively better between the indicated years. Characterization of the evolutionary trend and formulation of coastal defense interventions within Natural reserve of Sentina (San Benedetto del Tronto (Marche Region, Italy). Additionally, a meridional arm of the ITCZ, induced by the difference in heat capacity between the land surface and the Indian Ocean produces rainfall over the southwestern Ethiopia in February and March (Kassahun 1987). 2004; Diro 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. Mon Weather Rev 131:7494. Precipitation in Ethiopia averaged 845.03 mm from 1901 until 2021, reaching an all time high of 1102.46 mm in 1967 and a record low of 641.32 mm in 1984. The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. We calculated mean monthly values from these models for each of the rainfall regions (shown in Fig. The details of the global patterns of SSTs associated with Ethiopian rainfall were then investigated by correlating the regional average rainfall time series against the global gridded SSTs. 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! The interaction between human population and agricultural production is complex.Intense debates have been continued on population growth against agricultural development. Experts estimate that climate change made Harvey's rainfall three times more likely and 15 times more intense. 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. Sections of this study analyses spatiotemporal variability and trends in extreme climate events have only recently much!

Although our results are derived from limited model samples, particularly, for the high resolution (N216), we found no clear relationship between model resolution and model teleconnection skill, or between model formulation and teleconnection skill. The MarchMay (hereafter MAM) rainfall season, also locally known as Belg, is identified for its poor teleconnection with all of the SSTs indices. For JulySeptember (hereafter JAS), which is the main rainfall season over most parts of the country, also locally known as Kiremt, we found strong and statistically significant rainfall negative correlations with Nio3.4, the IOD and CIndO SSTs. 0000004982 00000 n The northward advance of the ITCZ produces orographic rains in MarchMay over southwestern, south-central, and east-central Ethiopia. Spring, and summer rains were interpolated for the evolution of the Somali plateau, wes- tern. local physiography nor by the expansion of the urban areas. In analyzing the results, the researchers found that we'll likely cross threshold for dangerous warming (+1.5 C) between 2027 and 2042. Afr J Ecol 45:416. 0000056870 00000 n Whole territory of Ethiopia is located in equatorial and subequatorial climate zones however altitude variety brings some features to weather conditions of the country. The views expressed are not necessarily those of DFID. A quasi-objective method was employed to define coherent seasons and regions of SST-rainfall teleconnections for Ethiopia. Then, these correlation maps were visually compared against the observed teleconnection plots shown in Fig. Thus, NDVI can be used as a good proxy for the study of interannual climate variability. 2008; Jury and Funk 2012; Viste and Sorteberg 2013). 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. 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). (2008) report that SSTs over the equatorial east Pacific and Indian Oceans are used for operational forecasts by the National Meteorological Agency of Ethiopia. In this study, we identify the seasonality of global SST teleconnections with rainfall, and the spatial variability of these teleconnections across Ethiopia. Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. 2009).

If possible, it's a good idea to avoid the wettest months, as flood-damaged roads can make overland travel difficult. body #site input[type="submit"] { For the CW-Ethiopian JAS rainfall season, both models show a poor ability to reproduce the teleconnections. 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 Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. Both models poorly represent the statistically significant teleconnections, except that HadGEM2 and the low resolution (N96) version of HadGEM3-GA3.0 better represent the association between the IOD and S-Ethiopian ON rainfall. 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.

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. Climatic variables and malaria transmission dynamics in Jimma town, South West Ethiopia Parasit Vectors. The aim of the study is to analyze the spatio-temporal variability and projection of rainfall and temperature (2021-2040) in Suha watershed, North West highlands of Ethiopia. We also note that HadGEM3-GA3.0 is a climate model that was under continuous improvement (Hewitt et al. 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. 1999; Behera and Yamagata 2003; Saji and Yamagata 2003; Marchant et al. Int J Climatol 21:9731005. Temperature in Ethiopia averaged 22.88 celsius from 1901 until 2021, reaching an all time high of 23.95 celsius in 2009 and a record low of 22.14 celsius in 1967. Also, this region is known for its dry climate during this season. However, such a study is lacking in many basins of Ethiopia. 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. Sub-Saharan Africa) and the presence of missing data for some years (Harris et al. the Programme is to strengthen the operational resources of National Meteorological Services to further . Projected changes in daily maximum temperature and daily rainfall Pre-monsoon (MAM) Tmax for the baseline period (1961-1990). Note that December rainfall has very little correlation with SSTs. 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. Timber Framing Slick, Mekele's annual temperatures are also relatively consistent, with April, May, and June being the hottest months.
