rainfall regions of ethiopia

It has three different climate zones according to elevation. https://www.nationalparks-worldwide.com/eaf/ethiopia/ethiopia-weather.html ern Somali regions who currently (2012) rely upon meager Belg rains for their livelihoods. Here is a brief overview of coffee in Ethiopia. These are: Summer rainfall region:This region comprises almost all parts of the country, except the southeastern and northeastern lowlands. Kolla (Tropical zone) - is below 1830 metres in elevation and has an average annual temperature of about 27 degree Celsius with annual rainfall about 510 millimetres. In this study, rainfall data of the past 50 years was used to study the basic statistical characteristics of the rainfall of this region. Investigating the influence of sea surface temperatures (SSTs) on seasonal rainfall is a crucial factor for managing Ethiopian water resources. Djibouti is a country in the Horn of Africa.It is bordered by Eritrea in the north, Ethiopia in the west and south, and Somalia in the southeast. The first leading patterns of rainfall and upper wind (averaged between 100 and 300 hPa) are highly correlated and exhibit similar features between simulation and observations over the northern, western, southwestern, and eastern regions of Ethiopia. Variability of rainfall and its current trend in Amhara region, Ethiopia Dereje Ayalew1,2*, Kindie Tesfaye1, Girma Mamo3, Birru Yitaferu4 and Wondimu Bayu5 1College of Agricultural and Environmental Sciences, Haramaya University, P. O. The two regions are identified based on the spatial distribution of high seasonal fractions of annual rainfall for the period 1979–2016. The number of people affected by the recent flooding in Somali Region of Ethiopia has exceeded over 300,000, says regional official. RAINFALL RELIABILITY IN ETHIOPIA RAINFALL RELIABILITY IN ETHIOPIA Lovett, R.; Wood, C. A. Analysis of the spatial distribution and the temporal trends of rainfall is crucial for water resource management, agricultural productivity and climate change mitigation (Ayalew et al. Rainfall regimes also vary across regions. characterising the rainfall pattern of the arid and semi-arid regions of Ethiopia. probabilistic categorical forecasts of regional Ethiopian rainfall. Several studies (Cheung Over CW-Ethiopia, JAS rainfall is significantly and negatively correlated with the Niño3.4, CIndO and IOD modes of SST variability. Rainfall and temperature are one of the most determinant climate patterns for the study area because more than 80% of the area’s agriculture is reliant on rain-fed. North eastern Ethiopia is one of the sensitive regions to climate variation particularly to temperature and rainfall changes. RAINFALL TRENDS AND VARIABILITY IN SELECTED AREAS OF ETHIOPIAN SOMALI REGIONAL STATE, SOUTHEASTERN ETHIOPIA SOLOMON TEKALIGN School of Geography and Environmental Studies, Haramaya University, P. O. 1. Verification is performed using rainfall data obtained from Ethiopian meteorological stations covering eight homogeneous rainfall regions used in the forecasts. Blue Nile basins, Ethiopia, each had only one rainfall sta-tion, despite a catchment area greater than 5000km2. Ethiopia. It is geographically located between 8°4′ to 9°19′ N latitude and 37°57′ to 39°10′ E longitude ().The Upper Awash basin covers an area of 11,620.2 km 2 with a reach length of 192 km. GERD, which has been a controversial project of Ethiopia, is being built a … Ethiopia + 6 more. Considering climate variability importance for agricultural activities in the region, the study is focused over potential cropping regions of Ethiopia as displayed in Fig. Korecha and Barnston (2007) found that interannual variability during this season is governed primarily by ENSO, but that more local factors near Africa and in the Atlantic and Indian Oceans play a role as well. The poor coverage introduces Govt. This shows the serious effect that climatic variation can have upon agricultural communities, especially in developing countries. Ethiopia’s climate is typically tropical in the south‐eastern and north‐eastern lowland regions, but much cooler in the large central highland regions of the country. 2012).Moreover, analyzing both inter-annual and intra-annual trends in rainfall offers intuitive information on the dynamics of soil moisture in rain-fed systems (Zhao et al. To the east is its coastline on the Red Sea and the Gulf of Aden.Rainfall is sparse, and most of the territory has a semi-arid to arid environment. Ethiopian economy is characterized by high dependency on rain-fed agriculture which has low adaptive capacity to ad-verse impacts of climate change (World Bank 2006; Conway and Schipper 2011).There are divergent rainfall trends across the country, which makes rainfall-runoff modeling and drought risk assessment difficult. 90% of Ethiopia’s population5. The combined Belg and Kiremt rainfall reductions total a loss of more than Ethiopia is in the tropical zone laying between the Equator and the Tropic of Cancer. This study was undertaken in the Upper Awash Basin, Ethiopia. This is far below the World Meteorological Organization (WMO) standard of one station for 100 to 250km2 in area for moun-tainous regions (WMO, 1994). 1976-12-01 00:00:00 N the last few years several highly populated areas of Ethiopia have been devastated by severe droughts. The curves are developed classifying Ethiopia into main five hydrological regions with similar rainfall patterns. Box 3015, 2601 DA Delft, The Netherlands 2Delft University of Technology, P.O. 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). We evaluate the performance of the forecast system for February–May and June–September rainy seasons over the period 1999–2011. Coffee is indegenous to Ethiopia and today the country produes some of the highest quality in the world. Rainfall Regions of Ethiopia. The summer rainfall over the JJAS region is negatively correlated with ENSO. This study examined the extent of seasonal rainfall variability, drought occurrence, and the efficacy of interpolation techniques in eastern Kenya. Global Economic ... Average Monthly Rainfall 1901 - 2009 (mm) The Climate Change Knowledge Portal is a hub of information, data and reports about climate change around the world. The variability of rainfall in both annual and seasonal scales were evaluated using coefficient of variation (CV), standardized rainfall anomaly, precipitation concentration index (PCI), and standardized precipitation index. Thus, the global SST anomalies that affect the Ethiopian rainfall in different seasons and regions should be clearly identified and studied to enhance the skill of the seasonal rainfall Analyses of rainfall variability utilized rainfall anomaly index, coefficients of variance, and probability analyses. The rainfall variability and trends over North Shewa investigated using gauge as well as gridded rainfall data from 1985 to 2018. Annual and monthly rainfall was fitted to 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. The rainfall from the highlands of Ethiopia, which goes into the Abbay River and passes through Khartoum has contributed a lot to the current flooding, which Sudan has not seen in a century. Mean annual temperatures are around 15‐20˚C in these high altitude regions, whilst 25‐30˚C in the lowlands. kiremt rainfall totals in the eastern, southern and south-western parts of Ethiopia. region. Although the method is skilful for some regions and seasons, it has little skill for the spring rains in the south of Ethiopia because of the fact that the ENSO signal is weaker during the spring. The flooding is caused by the heavy rainfall in the neighboring regions of Harari mainly Eastern part and Bale area Oromia Region of Ethiopia. The International Research Institute for Climate and Society (IRI) uses predictions Here you can query, map, compare, chart and summarize key climate … Mean annual rainfall ranges from less than 300 mm in the south-eastern and Box 138, Haramaya, Ethiopia. However, differences in altitude tend to add a number of variations, both in terms of temperatures and rainfall. This situation is not likely to improve in the near future. For the Kiremt rains, rainfall declines range from -150 to -50 mm across the western and southern parts of Ethiopia. Based on rainfall distribution, both in space and time, four rainfall regions can be identified in Ethiopia and the Horn. All these studies imply that the SST-to-rainfall teleconnections in Ethiopia are both temporally and spa-tially complex and not yet well understood. The application of Cluster Analysis (CA), on The rainfall over Ethiopia exhibited high variability over the study period. Ethiopia: COVID-19 Humanitarian impact - Situation Update No. Moreover, the variability of monthly rainfall, for instance in the dominant rainy season (JJAS) over western Ethiopia (categorized as subregions R-1, R-8, and R-9) accounts for ~65%–85% of the total rainfall variability over these regions and reaches its peak in July. In this study, we explore the possible mechanism of opposite ENSO effects on summer rainfall in the JJAS region (northern GHA) and autumn rainfall in the OND region (equatorial GHA). Box 33 Haramaya Ethiopia, Email: so.2011tek@gmail.com Abstract The pastoral and agropastoral communities are among the most vulnerable to climate Lowland areas usually see hotter temperatures than in the Highland regions, which cover a great deal of Ethiopia. The Belg/Gu/Ganna season in Ethiopia stretches from February to June and contributes 50-65% of the annual rainfall for the south-southeastern and up to 40% to the northeastern-eastern parts of the country. Ethiopia in three major rainfall regions that vividly identified the dominance of large rainfall dissimilarities and strong seasonality, which separate June-September (Kiremt) rain-benefiting from February-May (Belg) and October-January (Bega) rainfall regimes. 14, as of 18 October 2020 Format Situation Report Sources. Termed the kiremt rains, the June–September season accounts for some 50%–80% of the rainfall over Ethiopia’s agricultural regions. 2015). Ethiopia experiences two main climate seasons - a dry season and a rainy season. It is well understood that rainfall is highly variable under arid and semi-arid conditions. 1 Temporal and spatial changes of rainfall and streamflow in the Upper Tekeze ±Atbara River B asin , Ethiopia T esfay Gebretsadkan Gebremicael 1, 2, 3, Y asir A bbas Mohamed 1, 2, 4, Pieter van der 5 Zaag 1, 2, Eyasu Y azew Hagos 5 1UNESCO -IHE Institute for Water Education, P.O.
