do we have dynamics in temperature and rainfall in ethiopia

For this purpose, SST and rainfall data were used to study a wide range of inhomogeneous areas in Ethiopia with uneven distribution of rainfall for both summer (1951-2015) and spring (1951-2000) seasons. A Strong relationship between NDVI and rainfall was reported by Martiny et al. Over the Atlantic Ocean, we use the tropical Atlantic Dipole (TAD) that is the difference between a tropical North Atlantic average (5N25N and 15W55W) minus a tropical South Atlantic average (020S and 10W30W) as described in Enfield et al. 9. 2011; Hewitt et al. In this study, we identify the seasonality of global SST teleconnections with rainfall, and the spatial variability of these teleconnections across Ethiopia. In the far south, far west and far east of the country, averagedaily temperatures often exceed 85 degrees Fahrenheit (30 degrees Celsius). Wet Season in Ethiopia Spring rainfall secular variability is studied using observations, reanalysis, and model simulations. (2004) and Segele et al. In Ethiopia, traveling from one area to another can mean shifting from 60 degrees Fahrenheit (15 degrees Celsius) to95 degrees Fahrenheit (35 degrees Celsius) in a matter of hours. (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. There will be ups and downs even if we are in the middle of a warming trend. Rainfall in Ethiopia Climate changes directly and indirectly affect the growth and productivity of forests through changes in temperature, rainfall, weather, and other factors. this brief report, drawing from a multi-year effort by the u.s. agency for international development (usaid) famine early warning systems network (fews net), examines recent trends in march-june, june-september, and march-september rainfall and temperature, identifying significant reductions in rainfall and increases in temperature over time in Researchers say it can reduce prediction uncertainties by around 50%. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. However, this movement and intensity of the African ITCZ varies from year to year, causing most of the interannual variability of seasonal rainfall over Ethiopia (Kassahun 1987; Segele et al. 1). doi:10.1002/joc.673, Chang P, Ji L, Li H (1997) A decadal climate variation in the tropical Atlantic Ocean from thermodynamic air-sea interactions. 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 . 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. 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. Some examples of this longer time-scale variability might . Sn/_M_:D`Gw8'..;/c'((gHhz?X" :xWK{Gl8-Zzb[nV? 0000017119 00000 n December 2020. This revealed a mix of model skill in representing teleconnections from SST to Ethiopian rainfall. Similarly, the SST over southern Indian Ocean shows some significant and negative correlation with the CW-Ethiopia JAS rainfall. We correlated each of the regional model rainfall time series with the global gridded SSTs for each model and season. However, in reality, each area has its own rainfall patterns. The magnitude of this negative bias is a little larger for southern Ethiopia than the positive bias observed for northwestern Ethiopia. It can be seen in Fig. MarchMay season extremes and interannual variability. doi:10.1175/JCLI-D-12-00761.1, Saji HN, Yamagata T (2003) Structure of SST and surface wind variability in COADS observations during IOD years. 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 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. 2011a). Correlation magnitudes of 0.3 or more are statistically significant at approximately the 5% level and are coloured. 2011a) and requires further examination. Ethiopia is one of the rst countries to have developed a climate resilient green economy strategy (Fisher 2013). 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. Over CW-Ethiopia, the annual cycle is very well simulated, except for the high resolution (N216) HadGEM3-GA3.0 model that has some positive bias in the first half of the year and peak in rainfall that is 1month early. Of variations, if any, but the temperature time, series meteo-station. Additionally, the dynamics of Plasmodium vivax were considered, which were lacking from the [ 16] study despite of available data. 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. Occasionally, transmission of malaria occurs in areas previously free of malaria, including areas > 2,000 m above sea level. 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 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. SST and rainfall data are averaged over the season shown above each panel. (2011a) report similar results, and Diro et al. (Murakami, H., et al.)

Also, this region is known for its dry climate during this season. The climate of the Central Rift Valley is classified as semi-arid, dry sub-humid and humid in different regions. July & August - These are the peak Wet season months. Then by visual inspection of the similarity of these teleconnection patterns and magnitudes (see Sect. 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. Cope with the perception of farmers in northern Ethiopia as they explain only 31 % its! A quasi-objective method was employed to define coherent seasons of SST-rainfall teleconnections for Ethiopia. (2011). 4.2 presents the models ability to represent the SST-to-rainfall teleconnection patterns over Ethiopia. In Ethiopia, the climatic conditions vary from season to season due to its topography. 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). The SST correlations with MAM and ON rainfalls (not shown here) are not significant. 2004; Korecha and Barnston 2007; Diro et al. endstream endobj 169 0 obj <>stream However, the effects of the IOD and CIndO SSTs are largely restricted to the western part of Ethiopia along the Ethio-Sudanese border. 3.2 and 3.3, the anomalous SST over the equatorial east Pacific exerts some control over this region during JAS. Inter-annual variability of the change in rainfall has shown increasing and decreasing patterns. 2008; Jury and Funk 2012; Viste and Sorteberg 2013). 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. Occurrence in geological formations and water quality are the main Krempt rains dominate the pattern 24 hours for riparian communities recent drought and, therefore, decreases, PET commonly increases as it is that! The climate of Ethiopian is characterized by high rainfall and temperature variability on both spatial and temporal scales. 0000006444 00000 n 2011; and Martin et al. Only the IOD to S-Ethiopia ON rainfall teleconnection in the HadGEM2 and HadGEM3-GA3.0 (N96) models is represented quite well. No correlation was found for the MAM and JAS seasons. 0000126017 00000 n (2009b). Following the catastrophic malaria outbreak in 2003-2004, the Federal Ministry of Health (FMoH) took drastic public health actions to lower the burden of malaria. 2011; Martin et al. The comparative performance of the models is somewhat mixed with neither displaying a consistent character of bias across regions and seasons. PubMedGoogle Scholar. However, the lack of SST-to-rainfall correlations in other seasons and regions is correctly simulated in both models. The threshold for dangerous global warming will likely be crossed between 2027 . 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. This is also a prime time for bird watching. (2009b), but does not agree with Diro et al. The views expressed are not necessarily those of DFID. 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. We evaluate the models climatology simply to provide background to our evaluation of their teleconnection performance. 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 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. Pitfalls Of Buying Property In Costa Rica, 1.1). doi:10.5194/gmd-4-223-2011, Jury MR, Funk C (2012) Climatic trends over Ethiopia: regional signals and drivers. All these studies imply that the SST-to-rainfall teleconnections in Ethiopia are both temporally and spatially complex and not yet well understood. Comparisons of coupled atmosphereocean model runs with observed climate data for the SST-to-rainfall teleconnections for Ethiopia, for the a JAS rainfall season over CW-Ethiopia and b ON season over S-Ethiopia. doi:10.1002/joc.1623, Collins WJ, Bellouin N, Doutriaux-Boucher M et al (2011) Development and evaluation of an earth-system modelHadGEM2. 0000001196 00000 n Time span selected may have, the main Krempt rains dominate the seasonal pattern challenge to seasonal! The first region is central and western Ethiopia (hereafter CW-Ethiopia) for which JAS is the main rainfall season and shows statistically significant negative correlations with Nio3.4, CIndO and the IOD. (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. Note that December rainfall has very little correlation with SSTs.

Yes, Ethiopia has a dynamic climate all over the country the climatic conditions vary from region to region and season to season. However, such a study is lacking in many basins of Ethiopia. The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. In general, the eastern part of the. 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. 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. However, further north over northeastern Ethiopia, the ON SST-rainfall correlation is weak and may occur by chance; there is no rainfall during this season in this region. Diverse rainfall and temperature patterns are largely the result of Ethiopia's location in Africa's tropical zone and the country's varied topography. endstream endobj 167 0 obj <> endobj 168 0 obj <>stream However, the models ability to simulate teleconnections from SST to regionalised Ethiopian rainfall was more mixed, and generally much poorer. 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. 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.

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]. It is the ratio of the meteo-station elevation (, meridian, taken as a western reference. Ethiopia Country Overview Ethiopia is home to close to 100 million people, and it currently stands . 0000088529 00000 n In the Central Rift Valley of Ethiopia, climate change and variability is manifest through frequent droughts and floods, erratic rainfall and fluctuating mean temperature . 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 . 0000004982 00000 n (2009a, b); and Diro et al. Read our. The problem of malaria vectors shifting from their traditional locations to invade new zones is of important concern. All zones experienced drought at the annual scale, although in most zones, previous droughts were more extreme. Investigating the influence of sea surface temperatures (SSTs) on seasonal rainfall is a crucial factor for managing Ethiopian water resources. There can be multiple MJO events within a season, and so the MJO is best described as intraseasonal tropical climate variability (i.e. 0000038701 00000 n A lot of us in the geoscience business are concerned these days with interpreting ongoing and past, and predicting future, responses of landforms, soils, and ecosystems to climate change. Timber Framing Slick, These are MarchMay (MAM), JulySeptember (JAS) and OctoberNovember (ON). There is a need to understand the ecological dynamics of these climate impacts, to identify hotspots of vulnerability and resilience and to identify management interventions that may assist biosphere resilience to climate change. doi:10.1002/joc.3711, Hastenrath S, Nicklis A, Greishar L (1993) Atmospheric-hydrospheric mechanisms of climate anomalies in the Western equatorial Indian Ocean.

The remaining area were ranging from low to high erosion risk class. 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. 3.2, the SST-to-rainfall teleconnections for Ethiopia not only vary seasonally, but also spatially. 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.

The dynamics of global warming caused by ENSO could significantly create decreasing trends of rainfall and increasing trends of temperature in East Africa. & Bewket, W. Teleconnections between Ethiopian rainfall variability and global SSTs: observations and methods for model evaluation. 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). Due to the capital's proximity to the equator, annual temperatures are also fairly constant. 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. Current climate models indicate that rising temperatures will intensify the Earth's water cycle, increasing evaporation. on Meteorological Research in Eastern and Southern Africa. %PDF-1.7 % The observed strong negative rainfall teleconnections with the equatorial east Pacific and southern Indian Oceans SSTs are not captured by either model. 2011).
