do we have dynamics in temperature and rainfall in ethiopia

In Ethiopia, rainfall and temperature change and variability are expected to have adverse impacts on agriculture and food security [10]. Correlations between anomalies of NDVI and values of rainfall are generally positive, indicating a positive response of photosynthetic activity to excess rainfall. The dynamics of global warming caused by ENSO could significantly create decreasing trends of rainfall and increasing trends of temperature in East Africa. It is clear that interannual rainfall variability in these two regions is strongly influenced by the SSTs anomalies over the equatorial east Pacific and Indian Oceans. /* stream Currently, the demand for climate model data is growing due to this increasing interest in climate information (Hewitt et al. Also, this region is known for its dry climate during this season. doi:10.1002/joc.1623, Collins WJ, Bellouin N, Doutriaux-Boucher M et al (2011) Development and evaluation of an earth-system modelHadGEM2. Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia (Conway et al. 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. Temperature in Ethiopia decreased to 23.35 celsius in 2021 from 23.38 celsius in 2020. 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. (2011a) report similar results, and Diro et al. (2009b). 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. 200 0 obj <>stream J Geophys Res 98:219235. This is also a prime time for bird watching. This review paper examines why and how climate, forest, and agriculture interfaces . Temperature, rainfall, and elevation were the major determinants of malaria incidence in the study area. Long-Run Coefficients and Short-Run Dynamics. The third region is NE-Ethiopia, where both its Main (JAS) and Small rainfall (MAM) seasons show insignificant correlations with SSTs. Towards Ethiopia's borders, elevations decrease and temperatures rise accordingly. 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. 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. 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. 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. In this regard, global circulation models (GCMs) are critical tools that aid our understanding of the complex global atmospheric circulation and also enhance weather and climate prediction skill (Collins et al. Located in the north of the country, Mekele is the capital of the Tigray region. We provide an overview of the seasonality and spatial variability of these teleconnections across Ethiopia. Even in the hottest months (March to May), average highs rarely exceed 77 degrees Fahrenheit (25 degrees Celsius). Throughout the year, temperatures drop quickly once the sun goes down, and frosty mornings are common. Jillian Dara is a freelance journalist and fact-checker. For the CW-Ethiopian JAS rainfall season, both models show a poor ability to reproduce the teleconnections. Regional and local information on climate extremes is critical for monitoring and managing the impacts and developing sustainable adaptation measures.

Therefore, this paper aimed to evaluate the spatial distribution and temporal trends of rainfall in Amhara region during the period of 1981-2017 using CHIRPS data. doi:10.2151/jmsj.81.169, Article The study attempts to identify global and more regional processes affecting the large-scale summer climate patterns that govern rainfall anomalies. 0000007328 00000 n Spring, and summer rains were interpolated for the evolution of the Somali plateau, wes- tern. 0000004484 00000 n Conf. From this, we computed indices of the important SST modes that are known to affect rainfall variability over Africa in general (see Rowell 2013), and Ethiopia in particular (e.g. 156 0 obj <> endobj The representation of these teleconnections in the HadGEM2 and HadGEM3-GA3.0 coupled climate models shows mixed skill. 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 forecast system used in the country. 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. (2006). Where values of the station altitude seasons except spring season exhibited similar non-significant Distribution analysis and the country the 2007 NMA report, temperature data are in, IBON 174/03 and Sabini help to indicate possible future changes with deviation! 10 For . 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. 2006; Ummenhofer et al. Nairobi, Kenya, pp 5357, Korecha D, Barnston A (2007) Predictability of June-September rainfall in Ethiopia. The following sections of this first chapter provide some general information about those components. As shown in Sects. 1.1). This page includes a chart with historical data for Ethiopia Average Precipitation. Segele et al. 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]. GCMs are based on a sound physical representation of the real world, and can consider both natural and anthropogenic climate change. Table 5 reveals the estimates of both the long- and short-run coefficients of the ARDL model.

April 17, 2015. Increased evaporation will result in more frequent and intense storms, but will also contribute to drying over some land areas. In late 2012, we began transitioning to an operational status, which we completed in early 2013. The OctoberNovember (hereafter ON) period is also known as the Small Rains, except usually with the inclusion of September in southern Ethiopia (Degefu and Bewket 2014) or the inclusion of December elsewhere in equatorial east Africa (Black et al.

In the United States, the strongest change in rainfall is in the southeast, the region closest to the pool of warm Pacific water. 0000004710 00000 n In this regard, our study considered all the three rainfall seasons (Kiremt, Belg and small rainfall) and presents an alternative approach to define rainfall regions based on the specific seasonal patterns and magnitudes of the SST-rainfall teleconnections. MRD 8:131138. As shown in Sect. 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. 2015: Journal of Climate, 28(23), DOI: 10.1175/JCLI-D-15-0216.1. 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). Malaria morbidity data recorded from 2010 to 2017 were obtained from all public health facilities of Boricha District in the Sidama regional state of Ethiopia. The warming/cooling event is strongly linked with reduced/enhanced TEJ and EALLJ wind systems, and associated with deficit/excessive rainfall amounts over CW-Ethiopia. Global Environ Change 21:227237. and the rain belt to the south. Rainfall in Ethiopia shows large variations across time and space, due to the complex topography and varying latitude of the country (Gamachu 1988). Precipitation in Ethiopia increased to 927.34 mm in 2021 from 919.47 mm in 2020. 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). The "1.5C Paris Agreement compatible" rating indicates that Ethiopia's climate policies and action are consistent with limiting warming to 1.5C.

This dataset provides monthly mean precipitation totals at 0.5 spatial resolution for the period 1901 to the present day. Global climate change remains one of the biggest environmental threats to human welfare over the coming century. The main findings of this study are summarised as follows. Time and Date. If possible, it's a good idea to avoid the wettest months, as flood-damaged roads can make overland travel difficult. Although no study has been conducted for the southern Ethiopian SeptemberNovember season, available studies conducted for the wider region of Equatorial East Africa (Saji et al. 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. xref This page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. Over S-Ethiopia all simulations show a rainfall deficit for the Main Rainfall season (MAM) and excessive rainfall for the Small Rainfall season (ON).

Int J Climatol 29:10751100. Throughout the rest of the year, precipitation is minimal and the weather is generally pleasant. To assess the models ability to represent these teleconnections from SSTs to Ethiopian rainfall, we also compared their teleconnections maps against those derived from observations. 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. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. A greater aspect of our weather and climate is its variability. GCMs are also acknowledged for their potential to be able to respond to unusual SST anomaly patterns and any consequential responses in teleconnections. These are MarchMay (MAM), JulySeptember (JAS) and OctoberNovember (ON). PubMedGoogle Scholar. Climate Variability. The variability of rainfall and temperature has various impacts on the natural ecosystem and human society. Meteorol Appl 15:7383. And our result is highly in agreement with the data reported by [35,36,37,38]. These declines have been leading to more intense and frequent droughts across the country.
