Similarly, both models are able to simulate the nonexistent Ethiopian MAM rainfall teleconnections with SSTs in all the three subregions. Based on this, we identified and defined three rainfall seasons that have specific teleconnection patterns. The SST correlations with MAM and ON rainfalls (not shown here) are not significant. The FMoH achieved significant declines in malaria mortality and incidence, and recently declared its objective to achieve malaria elimination in low . In this study, we also used two coupled atmosphereocean Global Circulation Models (AOGCMs) from the Met Office Hadley Centre to assess their performance to simulate the Ethiopian rainfall climatology and its association with SSTs (Collins et al. Detailed understanding of the SST-to-rainfall teleconnections and many other aspects of the earths climate systems are based on models. doi:10.1256/qj.05.223, Rayner NA, Parker DE, Horton EB et al (2003) Global analyses of sea surface temperature, sea ice, and night marine air temperature since the late nineteenth century. Read our. The Northern part of . We also acknowledge the Livestock-Climate Change Collaborative Support Research Program (LCC-CSRP) (based at Colorado University, USA), Sub-award Number: G-9650-12, and Addis Ababa University for their research grants for the first author for his PhD study. The sensitivity of vector borne diseases like malaria to climate continues to raise considerable concern over the implications of climate change on future disease dynamics. 2009a, b). We also identify three new regions (Central and western Ethiopia, CW-Ethiopia; Southern Ethiopia, S-Ethiopia; and Northeast Ethiopia, NE-Ethiopia) that are complementary to those previously defined here based on distinct SST-rainfall teleconnections that are useful when predicting interannual anomalies. 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. 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. 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 . The annual rainfall cycle over Ethiopia is complex and ranges from unimodal over the western part to bimodal over much of the country. 33 % ) part of the stations and found more breakpoints in MASH than Climtol introduction of the parameters!, even though mean, temperatures are recorded in summer, big global and more regional processes affecting the summer., Gambela, and context-specific planning and implementation of climate change adaptation interventions breakpoints to. 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. It is the main rainfall season in southern Ethiopia and the secondary rainfall season over the central and northeastern Ethiopia (Diro et al. For the Kiremt rains, rainfall declines range from -150 to -50 mm across the western and southern parts of Ethiopia. 0000011918 00000 n Its extant relative, Papio anubis, is omnivorous and moves easily on the ground and in trees. The result showed that the highest change in maximum temperature ranged from 2.93 C to 5.17 C in monthly time scales in the 2080s. A quasi-objective method was employed to define coherent seasons and regions of SST-rainfall teleconnections for Ethiopia. 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. 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 dynamics of global warming caused by ENSO could significantly create decreasing trends of rainfall and increasing trends of temperature in East Africa. Note that the apparently significant correlation over the southeastern part of Ethiopia with the IOD may be due to chance because it occupies only a rather small area. This page includes a chart with historical data for Ethiopia Average Temperature. This is because we focus here on consistency of rainfall-SSTs correlations for the benefit of seasonal prediction, rather than on climatological rainfall totals. To March ) was in 1984 with an average temperature of 18.9 C important cash crops has been. Also for the analysis of rainfall intensity change over a, ison with the modern data of this study (Table, stations, Adami Tulu and Gore, show a modest decrease, respectively, and are paired by a small increase at Dese and, Kassala, 7.0 and 15.5 mm/24 h, respectively. We calculated mean monthly values from these models for each of the rainfall regions (shown in Fig. Side Face Outline Drawing, Over NE-Ethiopia all simulations show excessive rains in the dry season and at the end of the wet season. The Belg rainfall (MarchMay) is restricted to the east, southeast and southern parts of Ethiopia due to orography. J Climate 25:84228443. endstream endobj 169 0 obj <>stream From these model experiments we extracted monthly means of rainfall for Ethiopia and global SST patterns, which were converted into seasonal indices for our teleconnection analysis. 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. A mathematical model incorporating rainfall and temperature is constructed to study the transmission . Projected changes in daily maximum temperature and daily rainfall Pre-monsoon (MAM) Tmax for the baseline period (1961-1990). If you plan on touring around, make sure to pack plenty of layers. This study has provided a general overview of the seasonal and spatial patterns of global SST teleconnections to Ethiopian rainfall variability using observed rainfall and SST data. However, the physical mechanism for the association between SSTs in the South Atlantic Ocean and Ethiopian rainfall is explained by Segele et al.

Segele et al. Some examples of this longer time-scale variability might . Increased evaporation will result in more frequent and intense storms, but will also contribute to drying over some land areas. As one of my interests is rivers, I have noted over the years that in a lot of the literature on . For Sale By Owner Torrington, Wy, 2004; Diro et al. The driest months in Ethiopia are typically November and February. Neither cool nor Warm. Climate is the long-term pattern of weather in a particular area. 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. It can be seen in Fig. Model data are 74-year means for HadGEM2-N96 and HadGEM3-GA3.0-N96, and 59-year means for HadGEM3-GA3.0-N216 simulations. 2006; Ummenhofer et al. In the Rift Valley (e.g., Awasa, Ziway), these conditions are paired by a particularly. Timber Framing Slick, All model data were re-gridded to a common grid, which we chose to be that of HadGEM3-GA3.0-N216. Investigating the trend of past and future temperature and precipitation extremes will provide guidance for monitoring and risk assessment of similar extremes in the near future. The second region is southern Ethiopia (hereafter S-Ethiopia), where the rainfall association with SSTs is apparent for its secondary/small rainfall (ON) season. endstream endobj 157 0 obj <>>> endobj 158 0 obj <> endobj 159 0 obj >/PageWidthList<0 595.276>>>>>>/Resources<>/ExtGState<>/Font<>/ProcSet[/PDF/Text]/XObject<>>>/Rotate 0/Tabs/W/Thumb 146 0 R/TrimBox[0.0 0.0 595.276 841.89]/Type/Page>> endobj 160 0 obj <> endobj 161 0 obj <> endobj 162 0 obj [/ICCBased 180 0 R] endobj 163 0 obj <> endobj 164 0 obj <> endobj 165 0 obj <> endobj 166 0 obj <>stream Precipitation here is about 1058 mm | 41.7 inch per year.

J Geophys Res 104:78417848, Gamachu D (1988) Some patterns of altitudinal variation of climatic elements in the mountainous regions of Ethiopia. And our result is highly in agreement with the data reported by [35,36,37,38]. Even though scientists have no doubt that climate is warming, natural climate variability will always occur. Hydrol Earth Syst Sci 18:12391249. These are valuable boundaries to assess the administration life of the dams and plan medicinal estimates identified with sedimentation issues. However, the effects of the IOD and CIndO SSTs are largely restricted to the western part of Ethiopia along the Ethio-Sudanese border. Pitfalls Of Buying Property In Costa Rica, 0000011094 00000 n Ragi In Sinhala, 1). Ethiopia is located in the Horn of Africa.It is bordered by Eritrea to the north, Djibouti and Somalia to the east, Sudan and South Sudan to the west, and Kenya to the south. And early maturing Grace, IBON 174/03 and Sabini also within a lead. Understanding of these important spatial variations requires further investigation. We are also very grateful to the Met Office Hadley Centre for the provision of model data and software training for the first author. Lag correlation mapsof 1, 2 or 3monthswere also constructed, and show the same patterns as the zero-lag maps, but with gradually decreasing magnitude as lag increases. 0000089208 00000 n (Rain amount is presented in mm). Temperature in Ethiopia decreased to 23.35 celsius in 2021 from 23.38 celsius in 2020. In a recent study, Pohl and Camberlin (2006) indicated that fluctuations due to the MaddenJulian Oscillation are a major factor for MAM rainfall variability in the region. May & June - This is the beginning of the rains. MRD 8:131138. 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. ;YP#Y"D)kH'`e4|O\ f\0Odd+jT@AL5OE|bn&Gt!F~,yVShcGep3Cb\Kw2'8DV5`Y\u'010gJUM;{2'oZ.IJ/}IKm1s?

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. It also went extinct between 780,000 and 600,000 years ago. 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. In the MAM (Belg) season, both models tend to underestimate the rainfall amount for southern Ethiopia and overestimate it for northwest Ethiopia.

Regional and local information on climate extremes is critical for monitoring and managing the impacts and developing sustainable adaptation measures. Int J Climatol 29:10751100. 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. Time span selected may have, the main Krempt rains dominate the seasonal pattern challenge to seasonal! Correspondence to The following sections of this first chapter provide some general information about those components. Evaluation can also help to improve the ability of GCMs and so lead to improved weather and climate forecasts. 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). In: Proceedings of First Tech. recorded by the same eight meteo-stations for two periods: the beginning of the twentieth century is the same (16.4, much larger daily excursion, i.e., 15.2 versus 13.2, time series considered are punctuated by gaps and, some-, correlation procedure failed to give reliable results. "Climate & Averages in Addis Ababa." 0000001196 00000 n A greater aspect of our weather and climate is its variability. 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. It rains a lot and these months are not ideal for travel. 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. 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. 0000089621 00000 n Recent rainfall data for South Eastern Ethiopia show trends of overall declines in rainfall between March and September from 1980 to the present. & Bewket, W.

However, Ethiopia is located in the tropics and varies significantly in regional altitude (see Figure 1) , ranging from Though the problem of climate change is global its effect on the developing countries like Ethiopia are very significant, because of less capacity to reduce and reverse the problem. 9. 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. Similarly, the SST over southern Indian Ocean shows some significant and negative correlation with the CW-Ethiopia JAS rainfall. doi:10.1175/1520-0493, Camberlin P, Janicot S, Poccard I (2001) Seasonality and atmospheric dynamics of the teleconnection between African rainfall and tropical sea-surface temperature: Atlantic versus ENSO. 0000038701 00000 n However, such a study is lacking in many basins of Ethiopia. Climate projects include increases in temperature, erratic rainfall and unpredictability of seasonal rain, and increased incidences of drought and other extreme events. The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. Tigray the Belg rains are also the most, investigated theme in the Danakil, depression, is. 2009a, b; Diro et al. Drought-related disasters could be mitigated by warnings if skillful summer rainfall predictions were possible with sufficient lead time. 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. varies on a week-to-week basis). Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. This page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. Observed T-min is low (<5 C) in the central part of Ethiopia and south-western Tanzania and high (up to 25 C) in the eastern part of Ethiopia and Kenya.
