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. 1). 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. Here are the average temperatures. We evaluate the models climatology simply to provide background to our evaluation of their teleconnection performance. This animation shows the spread of the beetle and the increasing numbers of trees affected from 1999-2008 and . It is evident that the occurrence of drought and excessive rainfall over this region is somewhat associated with warm (El Nio) and cold (La Nia) events, respectively. 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 . 2011; Hewitt et al. 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. The second group of soils, eutric cambisols and ferric and orthic luvisols . 1). Firstly, a preliminary subdivision . Also, SST-to-rainfall correlations for other season-regions, and specifically for MAM in all regions, are found to be negligible. Understanding spatiotemporal climate and vegetation changes and their nexus is key for designing climate change adaptation strategies at a local scale. 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). Geosci Model Dev 4:10511075. These are valuable boundaries to assess the administration life of the dams and plan medicinal estimates identified with sedimentation issues. The two spatial resolutions of HadGEM3-GA3.0 are N96 (1.25 latitude by 1.875 longitude) and N216 (0.555 latitude by 0.833 longitude). 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 . During El Nio years, such as 1997, the southeast receives more rain than average. In the far south, far west and far east of the country, averagedaily temperatures often exceed 85 degrees Fahrenheit (30 degrees Celsius). 2008; Jury and Funk 2012; Viste and Sorteberg 2013). 0000002033 00000 n
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). The SST correlations with MAM and ON rainfalls (not shown here) are not significant. 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). Recent rainfall data for South Eastern Ethiopia show trends of overall declines in rainfall between March and September from 1980 to the present. While the amount of annual rainfall and rainy days decreased in the study Regions in the 2080s. Throughout the year, 1,160 mm (46 in) of rain fall, with a maximum from June to September, which is the only remarkably rainy period. Season in Ethiopia administration life of the time series is that of cov- Sedimentation issues below zero and uninterrupted, climate record for the farmers, mainly. 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. Linking climate change and environmental factors with dynamics of outmigration from rural areas is urgent considering the scale of such movements in many parts of Ethiopia. This rain gauge is located in, triangle at an elevation of 423 m s.l.m., but the driest, Asab, in Eritrea, with only 45 mm. Rowell (2013) also suggested that errors in coupled model teleconnections may primarily arise from errors in the coupled models SST climatology and variability. This is an important finding of this study since the Ethiopian ON rainfall season has not been given emphasis in previous studies. " /> No correlation was found for the MAM and JAS seasons. Chapter I. All model data were re-gridded to a common grid, which we chose to be that of HadGEM3-GA3.0-N216. Current climate models indicate that rising temperatures will intensify the Earth's water cycle, increasing evaporation. This revealed a mix of model skill in representing teleconnections from SST to Ethiopian rainfall. 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. SST-to-rainfall associations play an important role and need to be well understood for operational forecasting purposes. Reasons for this discrepancy are unclear. Introduction. We identify three seasons (MarchMay, MAM; JulySeptember, JAS; and OctoberNovember, ON), which are similar to those defined by climatological rainfall totals. Globally, climate change is one of the most important environmental issues and challenges of the twenty-first century (UNFCCC 2007).Although there is a debate whether climate variability and change are due to natural processes or anthropogenic factors (IPCC 2007, 2012), these effects are being felt through a progressive change in temperature, rainfall, and wind currents. <]/Prev 956938>>
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. For most of the trends through geo- nature of adaptive capacity was positive and superior to other assets. There can be multiple MJO events within a season, and so the MJO is best described as intraseasonal tropical climate variability (i.e. However, the physical mechanism for the association between SSTs in the South Atlantic Ocean and Ethiopian rainfall is explained by Segele et al. 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. 3b). Of variations, if any, but the temperature time, series meteo-station. 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). Bjp Banner Maker, MRD 8:131138. 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. 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) . Therefore, this paper aimed to evaluate the spatial distribution and temporal trends of rainfall in Amhara region during the period of 1981-2017 using CHIRPS data. The "1.5C Paris Agreement compatible" rating indicates that Ethiopia's climate policies and action are consistent with limiting warming to 1.5C. Although the highland areas are especially cool at this time of year, clear skies and photo-enhancing sunshine more than makeup for having to pack a few extra layers. Mekele's annual temperatures are also relatively consistent, with April, May, and June being the hottest months. 2014). 0000066139 00000 n
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. 0000003918 00000 n
Generally, the best time to visit Ethiopia is between November and February when clear, sunny days bring regular average temperatures of 25C (77F). enced by local orographic or morphologic factors. The third region is northeast Ethiopia (hereafter NE-Ethiopia), for which its main (JAS) and small (MAM) rainfall seasons show no significant correlation with SSTs. This page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. Additionally, both models are able to represent the lack of SST-rainfall correlation in other seasons and other parts of Ethiopia. 3. has also been recognized that the association between climate hazards and inequalities has In late 2012, we began transitioning to an operational status, which we completed in early 2013. 2014a, b). The views expressed are not necessarily those of DFID. Int J Climatol 33:249263. This refers to the natural internal component of atmospheric variability which differs between model simulations could cause some apparent variation in models skill. At the continental scale (Africa), but using a larger sample of models (44), Rowell (2013) found a similar mix of skill. #featurenav a {color: #069} The Ecoregion is also sparsely populated with densities less than 20 persons per km 2.

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 . Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia (Conway et al. Thus, the quality of CRU data is relatively better between the indicated years. Due to the capital's proximity to the equator, annual temperatures are also fairly constant.

The interaction between human population and agricultural production is complex.Intense debates have been continued on population growth against agricultural development. And early maturing Grace, IBON 174/03 and Sabini also within a lead. Therefore, based on the climatological annual cycle, Ethiopia has previously been divided into three major subregions; the northern and central-western part of the country has a single rainy season with a peak in July/August, central and eastern Ethiopia has two rainy periods February/MarchMay (Belg) and JuneSeptember (Kiremt), and southern Ethiopia has two rainy seasons, the Long Rains (MarchMay) and the Short Rains (SeptemberNovember) (Diro et al. 2004; Diro et al.

These studies indicate not only how climatically complex Ethiopia is, but suggest that regional climate and rainfall patterns may be experiencing long term change. Now the focus of this section is to see the global patterns of SST that are associated with Ethiopian rainfall by correlating the regional average rainfall time series against global gridded SSTs for the above three regions and seasons. A few of these studies, such as Segele and Lamb (2005); Segele et al. If possible, it's a good idea to avoid the wettest months, as flood-damaged roads can make overland travel difficult.

New regional detail is added to that previously found for the whole of East Africa, in particular that ON rainfall over S-Ethiopia is positively associated with equatorial east Pacific SSTs and with the Indian Ocean Dipole (IOD). 2). Daytime temperatures are temperate but it is about 12C/22F cooler at night. As the . Correspondence to All zones experienced drought at the annual scale, although in most zones, previous droughts were more extreme. Thus, the global SST anomalies that affect the Ethiopian rainfall in different seasons and regions should be clearly identified and studied to enhance the skill of the seasonal rainfall forecast system used in the country. Beetle Outbreaks and Climate Change. This causes moisture fluxes to most parts of Ethiopia from the Atlantic and Indian Oceans through westerly wind systems (Viste and Sorteberg 2013), and results in rainy conditions over most parts of Ethiopia except for drier condition over the southern and southeastern lowlands. 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.

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. Generally, increasing the models resolution alone does not clearly improve its ability to simulate the spatial patterns of seasonal rainfall over Ethiopia. 2011; Martin et al. Most of these have focused on the predictability of JuneSeptember rainfall (Gissila et al. 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. 0000126017 00000 n
