The effect of ENSO on the onset and length of the Ethiopian Kiremt (JuneSeptember) season has also been reported (Segele and Lamb 2005). (Rain amount is presented in mm). This result generally supports the findings reported by Segele et al. 0000007328 00000 n
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. 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. Similarly, the SST over southern Indian Ocean shows some significant and negative correlation with the CW-Ethiopia JAS rainfall. 3a, b (and also with those not shown).

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. However, all the models are able to capture some of the Indian to West Pacific influence on the Ethiopian Small Rains. Nikon D5100 Manual Video, 1999; Behera and Yamagata 2003; Saji and Yamagata 2003; Marchant et al. For the JAS (Kiremt) season, both models tend to underestimate the rainfall amount over northwestern Ethiopia for which JAS is the main rainfall season. Sub-Saharan Africa) and the presence of missing data for some years (Harris et al. (2011). A quasi-objective method is employed to define coherent seasons and regions of SST-rainfall teleconnections for Ethiopia. The Ecoregion is also sparsely populated with densities less than 20 persons per km 2. doi:10.1175/2008JCLI2537.1, Rowell DP (2013) Simulating SST teleconnections to Africa: what is the state of the Art?

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). July & August - These are the peak Wet season months. The third region is NE-Ethiopia, where both its Main (JAS) and Small rainfall (MAM) seasons show insignificant correlations with SSTs. At 1,000 m, the mean values are close to 30. mainly, in the steppe areas and the Danakil Desert (Fig. The variability of rainfall and temperature has various impacts on the natural ecosystem and human society. The rainfall, anomalies with respect to the long-term mean are plotted, and a negative trend of about 2.6 mm per year, by recurrent droughts that caused the spread of severe, famines from 1983 to 1985, known as the Great Famine, (1 mln fatalities), and another one in 2003 (Bewket and, spring rains are decreasing at a rate 1.5 times faster than the, monsoon summer rains.

These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. (2008) has used the SST anomalies from the Atlantic, Indian and Pacific Oceans to predict the MAM rainfall. Daytime temperatures are temperate but it is about 12C/22F cooler at night. doi:10.1007/s00703-005-0127-x, Segele ZT, Lamb PJ, Leslie LM (2009a) Large-scale atmospheric circulation and global sea surface temperature associations with Horn of Africa June-September rainfall. ~#[y7Q(s9E2G9

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. As the results point to 2009 as a result, precedence and immediate attention should be given to those prone. Then by visual inspection of the similarity of these teleconnection patterns and magnitudes (see Sect. Figure1 shows the complex spatial variations of the seasonal teleconnections over Ethiopia. 2), and compared that against the observations (CRU TS3.0). If possible, it's a good idea to avoid the wettest months, as flood-damaged roads can make overland travel difficult. 3.2, the SST-to-rainfall teleconnections for Ethiopia not only vary seasonally, but also spatially. Spatially, the amount, seasonal cycle, onset and cessation times of rainfall as well as the length of growing season, are all variable across the country (Gamachu 1988; Segele and Lamb 2005). startxref
This dataset provides monthly mean precipitation totals at 0.5 spatial resolution for the period 1901 to the present day. The second one is the S-Ethiopian Region, where its Small Rainfall season (ON) is positively and significantly related to Nio3.4 and the IOD. Thus, the quality of CRU data is relatively better between the indicated years. It was predicted that its climate will warm up 0.7C and 2.3 by the 2020s and between 1.4C and 2.9C by the 2050s.

Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. Diverse rainfall and temperature patterns are largely the result of Ethiopia's location in Africa's tropical zone and the country's varied topography. Temperature, rainfall, and elevation were the major determinants of malaria incidence in the study area. Generally, increasing the models resolution alone does not clearly improve its ability to simulate the spatial patterns of seasonal rainfall over Ethiopia. And percentage of variance explained by C/ ( C0 + C ) = %! However, such a study is lacking in many basins of Ethiopia. Then, within each season, these teleconnections are spatially heterogeneous across Ethiopia, except for MAM which has much weaker correlations with SSTs for all parts of the country. 3.1), we identified three broader teleconnected rainfall regions (Fig. Climate change will have key impacts on agriculture, livestock, water and human health in Ethiopia.

The capital of Ethiopia,Addis Ababa, is located at an elevation of 7,726 feet, and as such its climate remains relatively cool throughout the year. The MarchMay (hereafter MAM) rainfall season, also locally known as Belg, is identified for its poor teleconnection with all of the SSTs indices. Researchers say it can reduce prediction uncertainties by around 50%. Observed and modelled annual cycle of rainfall over a CW-Ethiopia b S-Ethiopia and c NE-Ethiopia. The views expressed are not necessarily those of DFID. 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 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. 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 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 left-hand column shows the observed seasonal totals (CRU3.0) for reference. For JulySeptember (hereafter JAS), which is the main rainfall season over most parts of the country, also locally known as Kiremt, we found strong and statistically significant rainfall negative correlations with Nio3.4, the IOD and CIndO SSTs. Both climate variability and change have been occurring in Ethiopia. He also found HadGEM2 is amongst the better models, so we suggest it is likely that the HadGEM2 and HadGEM3-GA3.0 performance shown here in representing teleconnections to Ethiopia is probably no worse than many other models. 2006) are known to affect the equatorial east African Short rains, and here we show there are also significant correlations with southern Ethiopia. Her work has appeared in Travel + Leisure, USA Today, Michelin Guides, Hemispheres, DuJour, and Forbes. Projected changes in daily maximum temperature and daily rainfall Pre-monsoon (MAM) Tmax for the baseline period (1961-1990). (Murakami, H., et al.)

The analyses revealed that sheep (r = 0.535, P < 0.05) and cattle (r = 0.512, P < 0.05) were negatively affected by climate change. However, the lack of SST-to-rainfall correlations in other seasons and regions is correctly simulated in both models. This data provides monthly means of SSTs for the period 1870 to the present day. 2365 Unit 210 Exam Simulator, 0000009717 00000 n
We identify three seasons (MarchMay, MAM; JulySeptember, JAS; and OctoberNovember, ON), which are similar to those defined by climatological rainfall totals. Int J Climatol 29:10751100. 2004; Diro et al. Introduction. The data period used for this purpose was 41years (19551995). 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. 2011). doi:0.1111/j.1365-2028.2006.00707.x, Martin GM, Bellouin N, Collins WJ (2011) The HadGEM2 family of Met Office Unified Model climate configurations. 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). Therefore, there is an urgent need of documenting a complete and homogenized historical climate dataset as a prerequisite for reliable climate-related studies. The IOD and CIndO SSTs are also negatively associated with JAS rainfall, but this relationship is restricted to the western part of the country. Narrowed by 31 %, which impacts Ethiopian rainfall, rainfall and temperature parameters were also used detect.

Ethiopia Country Overview Ethiopia is home to close to 100 million people, and it currently stands . immersive college of winterhold sse Currently, the demand for climate model data is growing due to this increasing interest in climate information (Hewitt et al. Part I: associations of Wavelet-Filtered large-scale atmospheric circulation and global sea surface temperature. 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. 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. This period is considered the dry season as rainfall is at its lowest. If you enjoyed this article, please consider sharing it! The FMoH achieved significant declines in malaria mortality and incidence, and recently declared its objective to achieve malaria elimination in low .

Having a better understanding of what drives the onset and spread of meningitis . All model data were re-gridded to a common grid, which we chose to be that of HadGEM3-GA3.0-N216. (2004) and Segele et al. All zones experienced drought at the annual scale, although in most zones, previous droughts were more extreme. Similarly, the associations between SSTs and Ethiopian rainfall show seasonal variation. Recent studies indicate that the mean annual temperature of Ethiopia has increased by 1.3 C between 1960 and 2006, at an average rate of 0.28 C per decade and by 0.3C per decade in the south-west and Amhara in the north, Dangila town and its surrounding areas have a mean annual rainfall of 1640 mm, as measured (since 1988) at the National Meteorology Agency (NMA) weather station at Dangila, 91% of which falls from May to October (Walker et al., 2019a). Department of Geography and Environmental Studies, Addis Ababa University, P.O. 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. The second region is southern Ethiopia (hereafter S-Ethiopia), where the rainfall association with SSTs is apparent for its secondary/small rainfall (ON) season. May & June - This is the beginning of the rains. The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. Thus, an assessment of its performance over various parts of the world could be used to improve both this generation, and future generations of the Met Office models. 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.

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. Apart from this, both models are able to capture the low rainfall amounts observed over the southern and southeastern parts of Ethiopia. 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 theory, Ethiopia'srainy seasonbegins in April and ends in September. Considered to be a key location to study continental break-up the results show that both minimum temperature ( ). body #site input[type="submit"] { The effect exerted by the TAD, EqEAtl and CIndO during this season is also very weak and likely statistically insignificant for both southern and northeast Ethiopia. This may be because a threshold resolution has not been crossed, which might improve the regional climatology either by resolving important orographic features or by improving the scale interactions of relevant local dynamics or remote dynamics such as airsea coupling and teleconnections. 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. doi:10.1002/joc.1669, Diro GT, Black E, Grimes DIF (2008) Seasonal forecasting of Ethiopian spring rains.
