On the other hand, over the tropical Atlantic Ocean (Gulf of Guinea), the positive SST association with ON Rainfall that is simulated by HadGEM2 is nonexistent in the observations (Fig. 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. And early maturing Grace, IBON 174/03 and Sabini also within a lead. Afr J Ecol 45:416. This is also a prime time for bird watching. 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. doi:10.5194/hess-18-4311-2014. 2003). 3.2 and 3.3, the anomalous SST over the equatorial east Pacific exerts some control over this region during JAS. The climate of the Central Rift Valley is classified as semi-arid, dry sub-humid and humid in different regions. Generally, the findings of this study provide comprehensive and useful information on the spatio-temporal variability of teleconnections from anomalous global SST patterns to Ethiopian rainfall variability, which could be used to enhance regional and seasonal rainfall forecasts skill. 2009a, b). The climate of West Africa is expected to become more arid due to increased temperature and uncertain rainfall regimes, while its population is expected to grow faster than the rest of the world. 156 45

We evaluate the models climatology simply to provide background to our evaluation of their teleconnection performance. Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia (Conway et al. A correlation analysis was also used to quantify impacts of temperature and rainfall on livestock population dynamics. 2009). Towards Ethiopia's borders, elevations decrease and temperatures rise accordingly. (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. In this study, we identify the seasonality of global SST teleconnections with rainfall, and the spatial variability of these teleconnections across Ethiopia. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. Reg Environ Change 14:799810. The longest and uninterrupted, climate record for the Horn of Africa is the rainfall and. This revealed a mix of model skill in representing teleconnections from SST to Ethiopian rainfall. 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.

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. 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. Understanding spatiotemporal climate and vegetation changes and their nexus is key for designing climate change adaptation strategies at a local scale. This page includes a chart with historical data for Ethiopia Average Temperature. 3.1), we identified three broader teleconnected rainfall regions (Fig. Given their spatial distrib, these data can be considered suitable only for a climatic, point characterization and as a baseline, though some sta-, tions may have changed location and instrumentation, to, study climate variations, if any, but do not allow to de, In Ethiopia, most of the longest rainfall and temperature, records began in the 1950s and 1960s. Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. Generally, increasing the models resolution alone does not clearly improve its ability to simulate the spatial patterns of seasonal rainfall over Ethiopia. Precipitation in Ethiopia increased to 927.34 mm in 2021 from 919.47 mm in 2020. The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. (2009b), but does not agree with Diro et al. 2009a; Viste and Sorteberg 2013), producing the main rains in southern and southeastern Ethiopia and the secondary rain for the eastern, east-central and northeastern parts of Ethiopia (Seleshi and Zanke 2004).

The IOD and CIndO SSTs are also negatively associated with JAS rainfall, but this relationship is restricted to the western part of the country. Global climate change remains one of the biggest environmental threats to human welfare over the coming century. Many other records, started during the 1980s, following the impulse from the, Ethiopian Government to expand the network, partly in, response to the mid-1980s drought. 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. Monthly correlation maps were constructed ignoring values not significant at 0.5 level.

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). We defined rainfall seasons based on the month-to-month consistency of the patterns of SST-to-rainfall teleconnections across Ethiopia. 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. 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. endstream

Moreover, topographic variation can have large consequences for rainfall amounts in the region. Nature 385:516518. 2008; Jury and Funk 2012; Viste and Sorteberg 2013). Drought-related disasters could be mitigated by warnings if skillful summer rainfall predictions were possible with sufficient lead time. 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. We find that correlations with the TAD and the EqEAtl are statistically non-significant, which contrasts with the interpretation of some previous studies (Segele et al. 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. The spatial and temporal distribution of climatological rainfall in Ethiopia is largely controlled by the annual northsouth migration of the Inter Tropical Convergence Zone (ITCZ) (Kassahun 1987) over Ethiopias complex topography. 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. In contrast, the pattern of correlations for September is quite different, and that for December is statistically insignificant. endstream

It rains regularly but showers usually don't last long. Additionally, the dynamics of Plasmodium vivax were considered, which were lacking from the [ 16] study despite of available data. Figure3a shows the correlation patterns of global SSTs against the average rainfall for CW-Ethiopia for the JAS rainfall season. Investigating the influence of sea surface temperatures (SSTs) on seasonal rainfall is a crucial factor for managing Ethiopian water resources. It also interacts with other pressures on ecosystems, including degradation, defaunation and fragmentation. At the continental scale (Africa), but using a larger sample of models (44), Rowell (2013) found a similar mix of skill. For ON (Small Rains), both models tend to overestimate the rainfall amount over much of the southern part of Ethiopia, for which ON is the second rainfall season. Currently, the demand for climate model data is growing due to this increasing interest in climate information (Hewitt et al. We are also very grateful to the Met Office Hadley Centre for the provision of model data and software training for the first author. Int J Climatol 24:973983. 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. 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. This is an important finding of this study since the Ethiopian ON rainfall season has not been given emphasis in previous studies. 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. The aim of this study is to show that other variables than minimum temperature could be involved in the malaria dynamics in Ethiopia, from 1985 to 2007. 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. 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. Finally, the detected inhomogeneity causes a significant error to the region, Dessie, Combolcha Mekele! In the past, the The variations in rainfall and temperature regimes are expected to influence tree growth, leaf phenology, and survivorship through their impacts on photosynthesis, respiration and nutrient dynamics [11, 12]. The increment in minimum temperature is also more prominent in the 2080s and it is expected to rise by 4.75 C. JAS rainfall over CW-Ethiopia is negatively associated with SSTs over the equatorial east Pacific and Indian Ocean. 2011). 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 discussions above are based on local correlation results produced from five regional SST time series that are known to affect Ethiopian rainfall, using gridded seasonal rainfall amounts.

Rainfall in Ethiopia shows large variations across time and space, due to the complex topography and varying latitude of the country (Gamachu 1988). Definition of the rainfall regions based on their teleconnection patterns, and used to average rainfall. Jillian Dara is a freelance journalist and fact-checker. We found that both the HadGEM2 and HadGEM3-GA3.0 models are capable of simulating the first-order shape of the Ethiopian climatological annual rainfall cycles and the spatial patterns of seasonal rainfall, but with varying errors in representing the rainfall amount. Methods The rising temperature and variability in rainfall pattern have direct impact on crop production and food security [15]. 2009). 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 . However, such a study is lacking in many basins of Ethiopia. Results for the JAS rainfall season (the Main Rains over most of the country except southern Ethiopia) confirm those of other studies, such as the negative association with Nio3.4. 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.
