do we have dynamics in temperature and rainfall in ethiopia

Thus, NDVI can be used as a good proxy for the study of interannual climate variability. U&5vhOb$3$EM&K7 The MarchMay (hereafter MAM) rainfall season, also locally known as Belg, is identified for its poor teleconnection with all of the SSTs indices. - 81.89.100.63. (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. Figure3a shows the correlation patterns of global SSTs against the average rainfall for CW-Ethiopia for the JAS rainfall season. High erosion risk class intervals which ally, the coldest winter ( January March. Required fields are marked *, You may use these HTML tags and attributes:

. In analyzing the results, the researchers found that we'll likely cross threshold for dangerous warming (+1.5 C) between 2027 and 2042. However, all the models are able to capture some of the Indian to West Pacific influence on the Ethiopian Small Rains. Current climate models indicate that rising temperatures will intensify the Earth's water cycle, increasing evaporation. J Geophys Res 98:219235. However, in reality, each area has its own rainfall patterns. 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 . It usually occurs at altitudes < 2,000 m above sea level. 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. Google Scholar, Black E, Slingo J, Sperber KR (2003) An observational study of the relationship between excessively strong short rains in coastal east Africa and Indian Ocean SST. 2015: Journal of Climate, 28(23), DOI: 10.1175/JCLI-D-15-0216.1. 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. ]OB_ku.toi3~>[_qsYz-]KeeSYJlE@kAo[0hha67;i0{=~^{:=B& lB& lB& lB& lB& lB& l 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. They indicated that the warming/cooling phase over the equatorial east Pacific and west Indian Oceans is associated with a easterly/westerly wind anomaly along the tropical Indian Ocean, and results in enhanced/suppressed moisture flux that produce wet/dry conditions during the Small Rainfall season. Correlation maps were produced for the tropical SST regions (45N45S) that have the potential to affect rainfall variability in Ethiopia (Segele et al. 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. The observed strong negative rainfall teleconnections with the equatorial east Pacific and southern Indian Oceans SSTs are not captured by either model. Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. Dire Dawa lies in eastern Ethiopia and is the second largest city in the country after Addis Ababa. {gU6HJk ~ExmC4`Pg?< doi:10.1016/j.gloenvcha.2010.07.013, Degefu MA, Bewket W (2014) Variability and trends in rainfall amount and extreme event indices in the Omo-Ghibe River Basin, Ethiopia. Note that even in the warmer temperatures, shorts are not usually appropriate, so pack accordingly. The negative correlations of rainfall over CW-Ethiopia in the JAS season with ENSO is stronger (r=0.59) than with the IOD (r=0.34), while the positive correlation for S-Ethiopia rainfall in ON is perhaps a little stronger with the IOD (0.56) than with ENSO (0.45). Ethiopia's Climate Resilient Green Economy (CRGE) report identified that the health and water sectors are among the most vulnerable sectors to climate change in Ethiopia, alongside the agricultural sector.3 Currently, altered weather patterns are resulting in The climate of East Africa consists of three rainy seasons including . 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. 2011). If you're traveling to theDanakil Depressionor the Ogaden Desert in southwest Ethiopia, you don't have to worry about rain. However, the effects of the IOD and CIndO SSTs are largely restricted to the western part of Ethiopia along the Ethio-Sudanese border. Geosci Model Dev 4:10511075. It will be necessary to further explore this models sensitivity to resolution for the Ethiopian region, and to further improve its representation of the important physical processes. Meteorol Appl 15:7383. The amount of rainfall varies spatially within the country and within different regions in the country. Amasco Ceiling Fan Review, It also interacts with other pressures on ecosystems, including degradation, defaunation and fragmentation. 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. 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 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. The objectives of this study were (i) to analyze temperature, rainfall and vegetation greenness trends and (ii) determine the spatial relationship of climate variables and vegetation . However, Dinku et al. The views expressed are not necessarily those of DFID. Model using the A1B scenario Meteorol Mag, Segele ZT, Lamb PJ ( )! This is also a prime time for bird watching. 2011; Hewitt et al. For the same season, both models tend to overestimate the mean seasonal rainfall amount for the Ethiopian rift valley region that stretches from the northeast to the southwest part of Ethiopia. 1.1). Background: the influenza virus spreads rapidly around the elevation of the elevation! However, this type of information is not readily available at the necessary spatial resolution. Therefore, in order to help policymakers and developers make more informed decisions, this study investigated the temporal dynamics of rainfall and its spatial distribution within Ethiopia. The details of the global patterns of SSTs associated with Ethiopian rainfall were then investigated by correlating the regional average rainfall time series against the global gridded SSTs. These soils are formed from volcanic material and, with proper management, have medium to high potential for rain-fed agriculture. A Strong relationship between NDVI and rainfall was reported by Martiny et al. 2011; Hewitt et al. 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. 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 Int J Climatol 33:249263.

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. (2009b), this effect is exerted by weakening/intensifying the Mascarene high in response to the warming/cooling of the southern Indian Ocean, affecting the easterly flow on its northern flank, the moisture flux into East Africa, and then reducing/enhancing rainfall over Ethiopia. Similarly, both models are able to simulate the nonexistent Ethiopian MAM rainfall teleconnections with SSTs in all the three subregions. Climate change will have key impacts on agriculture, livestock, water and human health in 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. 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. 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.

"Climate & Averages in Addis Ababa." Part I: associations of Wavelet-Filtered large-scale atmospheric circulation and global sea surface temperature. The physical mechanisms of these teleconnections are found in many previous studies (Black et al. These rivers descend from the mountains in great falls, and like the other Ethiopian streams are unnavigable in their upper courses. Planning a trip toEthiopiarequires a basic understanding of the country's tricky climate in order to make the very most of your time there. 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. As one of my interests is rivers, I have noted over the years that in a lot of the literature on . Detailed understanding of the SST-to-rainfall teleconnections and many other aspects of the earths climate systems are based on models. 2003; Marchant et al.

The joint coherent spatio-temporal secular variability of gridded monthly gauge rainfall over Ethiopia, ERA-Interim atmospheric variables and sea surface temperature (SST) from Hadley Centre Sea Ice and SST (HadISST) data set is extracted using multi-taper method singular value decomposition . These declines have been leading to more intense and frequent droughts across the country. In October and November, the co-occurrence of anomalies over the east equatorial pacific and Indian Oceans (Black et al. Neither cool nor Warm. experienced drought conditions in the last decade. (2014). Degefu, M.A., Rowell, D.P. To attain this objective, both primary and secondary data from different sources were used. 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. 3b). For other Ethiopian regions in JAS and ON, which have no observed rainfall relationship with SSTs; this is correctly simulated in both models (not shown). New regional detail is added to that previously found for the whole of East Africa, in particular that ON rainfall over S-Ethiopia is positively associated with equatorial east Pacific SSTs and with the Indian Ocean Dipole (IOD). 0000151832 00000 n The Ecoregion is also sparsely populated with densities less than 20 persons per km 2. The comparative performance of the models is somewhat mixed with neither displaying a consistent character of bias across regions and seasons. Definition of the rainfall regions based on their teleconnection patterns, and used to average rainfall. Researchers say it can reduce prediction uncertainties by around 50%. 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). In the MAM (Belg) season, both models tend to underestimate the rainfall amount for southern Ethiopia and overestimate it for northwest Ethiopia. Jillian Dara is a freelance journalist and fact-checker. trailer Basic climatic parameters such as temperature, rainfall, relative humidity, wind, evapotranspiration, and aridity are considered and their spatial distribution is analyzed. 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. Monthly correlation maps were constructed ignoring values not significant at 0.5 level. We identify three seasons (MarchMay, MAM; JulySeptember, JAS; and OctoberNovember, ON), which are similar to those defined by climatological rainfall totals. The exact position of the ITCZ changes over the course of the year, oscillating across the (, and high erosion rates would be expected, but the occurrence, of soils with low erodibility, as reported by the USLE, synoptical variations associated with the position of the, ITCZ. Therefore, there is an urgent need of documenting a complete and homogenized historical climate dataset as a prerequisite for reliable climate-related studies. . Literature states that the coming decades will have experienced in higher temperature and change in precipitation intensity, and this may causes crop yield reduction in many countries in the world [9,16]. MRD 8:131138. This illustrates the challenges of correctly modelling teleconnections at subnational scales.

The empirical analysis also confirmed that the basin losses a total of about 89.6 Mt of soil annually. Thus, essential information can potentially be generated for decisions of national, regional, and local importance, such as water resource management, agriculture, transportation, and urban planning (Collins et al. Understanding spatiotemporal climate and vegetation changes and their nexus is key for designing climate change adaptation strategies at a local scale. 0000125978 00000 n The climate of Ethiopian is characterized by high rainfall and temperature variability on both spatial and temporal scales. Climate and vegetation dynamics are tightly coupled: regional climate affects land surface processes over a range of scales with unprecedented speed (IPCC 2007, Zhao et al 2011), while vegetation, in turn, affects climate through feedbacks via photosynthesis and evapotranspiration, changes in albedo and biogenic volatile organic compound emissions (Henderson-Sellers 1993, Fang et al 2003, Meng . The mean maximum. 0000089621 00000 n This variability ranges over many time and space scales such as localized thunderstorms and tornadoes, to larger-scale storms, to droughts, to multi-year, multi-decade and even multi-century time scales. Ethiopia is one of the rst countries to have developed a climate resilient green economy strategy (Fisher 2013). Even though scientists have no doubt that climate is warming, natural climate variability will always occur. Projected changes in daily maximum temperature and daily rainfall Pre-monsoon (MAM) Tmax for the baseline period (1961-1990). 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. 4.2 presents the models ability to represent the SST-to-rainfall teleconnection patterns over Ethiopia. doi:10.1002/joc.3560, Kassahun B (1987) Weather systems over Ethiopia. Temperature plays a major role in the center of Ethiopia loss is significant Ethiopia the Composite indices for sub-components showed that the humidity index is greater when it from Once raster layer of the influence of the meteorological component of this study are to. In the Rift Valley (e.g., Awasa, Ziway), these conditions are paired by a particularly. 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. The higher, values are found in the central and part of the northern, highlands and, subordinately, in the central portion of the, Somali plateau margin. Hampton Bay Cabinets Gallery, 2011a) and requires further examination. Precipitation in Ethiopia increased to 927.34 mm in 2021 from 919.47 mm in 2020. A mathematical model incorporating rainfall and temperature is constructed to study the transmission . Moreover, topographic variation can have large consequences for rainfall amounts in the region. Also, SST-to-rainfall correlations for other season-regions, and specifically for MAM in all regions, are found to be negligible. In this study, we used Budyko-like framework and remote sensing data to evaluate the spatial effects of climate and land surface changes on water availability in Ethiopia. Hydrol Earth Syst Sci 18:43114323.

Her work has appeared in Travel + Leisure, USA Today, Michelin Guides, Hemispheres, DuJour, and Forbes. East Africa is one of the most vulnerable regions of Africa to extreme weather and climate events. local physiography nor by the expansion of the urban areas. 2006) are known to affect the equatorial east African Short rains, and here we show there are also significant correlations with southern Ethiopia. Moreover, large (global) atmospheric circulation and sea surface temperatures, such as large-scale forcing through El Nio Southern Oscillation, Quasi-Biennial Oscillation, as well as west-east sea surface temperature gradients over the equatorial Indian Ocean are significantly influencing rainfall variability ( Omondi et al. 0000008184 00000 n Geosci Model Dev 4:223253. 156 0 obj <> endobj 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).

This refers to the natural internal component of atmospheric variability which differs between model simulations could cause some apparent variation in models skill. 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. conditions results in ample thermal differences (Fig. (1999). Correspondence to startxref The following sections of this first chapter provide some general information about those components. 2003), and the Zonal Dipole Mode over the Indian Ocean (IOD) (Saji et al. The Climate Resilient Green Economy (CRGE) strategy must, therefore, make greater efforts to embed young people's livelihoods and wellbeing in the strategy. Int J Climatol 17:117135. The driest months in Ethiopia are typically November and February. 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. The regional classifications by previous studies (e.g. Heavy precipitation events in most parts of the United States have increased in both intensity and frequency since 1901 (high confidence).There are important regional differences in trends, with the largest increases occurring in the northeastern United States (high confidence).In particular, mesoscale convective systems (organized clusters of thunderstorms)the main mechanism .

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. The soils of Ethiopia can be classified into five principal types. For the Kiremt rains, rainfall declines range from -150 to -50 mm across the western and southern parts of Ethiopia. The Belg rainfall (MarchMay) is restricted to the east, southeast and southern parts of Ethiopia due to orography. More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century. Although it is expected that in general climate models with higher resolution perform better (e.g. immersive college of winterhold sse The length of the Ethiopian Small Rainfall season that has significant correlations with SSTs is shorter than the more common definition for East Africa; it does not include December since this month is relatively dry and shows insignificant teleconnection with SSTs. Section4.1 presents the models performance for the annual rainfall cycle and the spatial distribution of seasonal rainfall, and Sect. Throughout the rest of the year, precipitation is minimal and the weather is generally pleasant. The results were in line with the recent studies that stated the frequency of the drought cycle has been changing over time in Ethiopia.
