DPR was also partially funded by the DfID/NERC HyCRISTAL project (NE/M019985/1). The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. 0000089208 00000 n More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century. 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. body #site input[type="submit"] { 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. 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. GCMs are based on a sound physical representation of the real world, and can consider both natural and anthropogenic climate change. 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. Climate Variability. Over the Pacific, we use the Nio3.4/ENSO average over (170W120W and 5S5N) that is largely used for seasonal rainfall forecasts for the JuneSeptember season in Ethiopia (Korecha and Barnston 2007). During Belg (DecemberFebruary), the ITCZ is located well south of Ethiopia and the country predominantly falls under the influence of dry warm and cool northeasterly winds. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. 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. Malaria has been Ethiopia's predominant communicable disease for decades. Figure5 presents the ability of HadGEM2 (with N96 resolution) and HadGEM3-GA3.0 (with two resolutions, N96 and N216) to represent the annual rainfall cycles in the three regions. %%EOF Narrowed by 31 %, which impacts Ethiopian rainfall, rainfall and temperature parameters were also used detect. doi:10.1175/1520-0442(2003)016, Saji NH, Goswami BN, Vinayachandran PN et al (1999) A dipole mode in the tropical Indian Ocean. 2004; Korecha and Barnston 2007; Diro et al.

Similarly, the SST over southern Indian Ocean shows some significant and negative correlation with the CW-Ethiopia JAS rainfall. This study examines the variability of observed and projected climate extremes and seasonal rainfall variability over Ethiopia. Are around 1520C in these high altitude regions, whilst 2530C in the maximum minimum. 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. 2014). Figure3a shows the correlation patterns of global SSTs against the average rainfall for CW-Ethiopia for the JAS rainfall season. 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. trailer A greater aspect of our weather and climate is its variability. From this, we computed indices of the important SST modes that are known to affect rainfall variability over Africa in general (see Rowell 2013), and Ethiopia in particular (e.g. 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. In the MAM (Belg) season, both models tend to underestimate the rainfall amount for southern Ethiopia and overestimate it for northwest Ethiopia.

(Murakami, H., et al.) (2011); and Martin et al. 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. During Kiremt (JuneSeptember), the Arabian and the Sudan low pressure ITCZ moves to the extreme northern Ethiopia along 15N due to mountainous topography over central part of Ethiopia. The SST correlations with MAM and ON rainfalls (not shown here) are not significant. J Climate 22:25412556. 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. 2023 Springer Nature Switzerland AG. 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. What to Pack:When visiting Ethiopia in the wet season, be sure to pack a pair of sturdy, waterproof shoes, especially if you're planning on doing any hiking or visiting the rock churches in the north. As we described in Sects. 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 . 0000013689 00000 n Current climate models indicate that rising temperatures will intensify the Earth's water cycle, increasing evaporation. Mekonnen Adnew Degefu. For our study, we considered the rainfall data for the period 19551995 to maintain the quality of data because in the early twentieth century some stations had not been established, and from the end of the twentieth century some stations had ceased reporting or their data was not readily available. Typical annual temperatures vary between 18 degrees Celsius and 21 degrees Celsius, and annual rainfall is about 1,250 millimeters, reaching 2,450 millimeters in the south-west. Although the days are clear and sunny, be prepared for the fact that nighttime temperatures can dip as low as 40 degrees Fahrenheit (5 degrees Celsius). 2011; Martin et al. . 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. In the United States, the strongest change in rainfall is in the southeast, the region closest to the pool of warm Pacific water.

We can see different climatic conditions mostly three seasons say. (2014). 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. Some examples of this longer time-scale variability might . 2003). 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. MarchMay season extremes and interannual variability. 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.

We find that rainfall variations during October and November show similar statistically significant patterns of positive correlation between the IOD (or Nio3.4) and gridded rainfall over Ethiopia. (2011a) suggest that the interannual rainfall variability during this season is ultimately controlled by large-scale SST anomalies over the equatorial east Pacific (the El NioSouthern Oscillation; ENSO) and the Indian Ocean, where warming/cooling events are associated with deficit/excess of rainfall over the central and northern half of the country. These data include quality controlled daily, monthly, seasonal, and yearly measurements of temperature, precipitation, wind, and degree days as well as radar data and 30-year Climate Normals. 2011a). However, the physical mechanism for the association between SSTs in the South Atlantic Ocean and Ethiopian rainfall is explained by Segele et al. Int J Climatol 28:16271638. The study used 4 km 4 Expand Prediction of bimodal monsoonal rainfall in the central dry zone of Myanmar using teleconnections with global sea surface temperatures (2009b). Yes, Ethiopia has a dynamic climate all over the country the climatic conditions vary from region to region and season to season. 1) long cycle crop growing area of the country. 2004). Poverty . 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. 3.1), we identified three broader teleconnected rainfall regions (Fig. Historic year 1984 km area ) Reg Plann 1 ( 4 ):65, Nations. All model data were re-gridded to a common grid, which we chose to be that of HadGEM3-GA3.0-N216.

Int J Climatol 33:19241935. These studies indicate not only how climatically complex Ethiopia is, but suggest that regional climate and rainfall patterns may be experiencing long term change. Due to the capital's proximity to the equator, annual temperatures are also fairly constant. doi:10.1002/joc.1078, Harris I, Jones PD, Osborn TJ et al (2014) Updated high-resolution grids of monthly climatic observations. doi:10.5194/gmd-4-223-2011, Jury MR, Funk C (2012) Climatic trends over Ethiopia: regional signals and drivers. 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. %PDF-1.7 % These changes influence complex forest ecosystems in many ways. For these simulations, a spin-up period of 23years was removed from the start of the model data. La Nia is the build up of cool waters in the equatorial . Ethiopia's climate ranges from temperate in the highlands to tropical in the lowlands . Afr J Ecol 45:416. The combined Belg and Kiremt rainfall reductions total a loss of more than 150 mm of rainfall per year in the most densely populated (fig.

The CRU monthly rainfall data set has also been used for more detailed teleconnection analysis over Upper Blue Nile Region (Zaroug et al. The OctoberNovember (hereafter ON) period is also known as the Small Rains, except usually with the inclusion of September in southern Ethiopia (Degefu and Bewket 2014) or the inclusion of December elsewhere in equatorial east Africa (Black et al. 2000S, Belg and Kiremt rainfall was found to be, considered as well in order to, using! Roberts et al. [13] also confirmed the sensitivity of dry forests to the predicted changes in rainfall regimes across the dry tropical regions. (Note that Rowell did not analyse MAM and JAS teleconnections to GHA.) Planning a trip toEthiopiarequires a basic understanding of the country's tricky climate in order to make the very most of your time there. The interannual rainfall variability in JAS for CW-Ethiopia and ON for S-Ethiopia, and the associated modes of SST (Nio3.4 and IOD), are shown in Fig. Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. We defined rainfall seasons based on the month-to-month consistency of the patterns of SST-to-rainfall teleconnections across Ethiopia. Located in the north of the country, Mekele is the capital of the Tigray region. Int J Climatol 21:9731005.

The main objective of this section is to evaluate the performance of HadGEM2 and HadGEM3-GA3.0 in representing Ethiopian rainfall variability and its teleconnections with global SSTs. 0000038701 00000 n volume129,pages 173186 (2017)Cite this article. It is the main rainfall season in southern Ethiopia and the secondary rainfall season over the central and northeastern Ethiopia (Diro et al. In the Central Rift Valley of Ethiopia, climate change and variability is manifest through frequent droughts and floods, erratic rainfall and fluctuating mean temperature . DYgw^.eJ[:e2W:s0>Ea2hal^t#"MG'cXuYCz[M'*. 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. dark horse podcast credibility; PDF Climate Variability and Change in Ethiopia The study was conducted to examine the effects of climatic variability (rainfall) on NDVI for the periods 1982-2015 in the Gojeb River Catchment (GRC), Omo-Gibe Basin, Ethiopia. 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. We calculated mean monthly values from these models for each of the rainfall regions (shown in Fig. 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. The physical mechanisms of these relationships are presented in previous studies (Segele and Lamb 2005; Segele et al. Rain falls infrequently in this area, although the river itself serves to keep the land fertile even at the height of the dry season.

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. These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. 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 . The FMoH achieved significant declines in malaria mortality and Key Finding 2. Researchers say it can reduce prediction uncertainties by around 50%. The empirical analysis also confirmed that the basin losses a total of about 89.6 Mt of soil annually. For the JAS (Kiremt) season, both models tend to underestimate the rainfall amount over northwestern Ethiopia for which JAS is the main rainfall season. 3a, b (and also with those not shown). 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 .

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. Ethiopia provides a good example of the influence of climate variability on a developing countrys economy. Because of the complex interactions between climate, agro-ecosystem dynamics and human management at farm to regional level, assessment studies of the impacts of climate change on agriculture have involved the use of computer simulations that link climate predictions of general circulation models (GCMs) together with crop models and land management decision tools . Drought-related disasters could be mitigated by warnings if skillful summer rainfall predictions were possible with sufficient lead time. The government of Ethiopia initiated a green economy policy to counter climate change and foster economic development such as the 2011 Climate Resilient Green Economy (CRGE). The data period used for this purpose was 41years (19551995). Here are the average temperatures. In Ethiopia, malaria is seasonal and unstable, causing frequent epidemics. As shown in Sect.
