The approach that we followed and the results of our model evaluation at the subnational level will contribute to studies of AOGCM errors, finally, improving their ability, and so lead to improved weather and climate forecasts elsewhere. Globally, climate change is one of the most important environmental issues and challenges of the twenty-first century (UNFCCC 2007).Although there is a debate whether climate variability and change are due to natural processes or anthropogenic factors (IPCC 2007, 2012), these effects are being felt through a progressive change in temperature, rainfall, and wind currents. The remaining length of time considered for our analysis is 74years for HadGEM2-N96 and HadGEM3-GA3.0-N96, and 59years for HadGEM3-GA3.0-N216. The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. In the United States, the strongest change in rainfall is in the southeast, the region closest to the pool of warm Pacific water. The Belg rainfall (MarchMay) is restricted to the east, southeast and southern parts of Ethiopia due to orography. 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 . For the, indicates a mean annual temperature increase of 0.28, hot days and a decrease of cold days. Korecha and Barnston 2007; Segele et al. Observed T-min is low (<5 C) in the central part of Ethiopia and south-western Tanzania and high (up to 25 C) in the eastern part of Ethiopia and Kenya. Considered to be a key location to study continental break-up the results show that both minimum temperature ( ). This page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. Because of the complex interactions between climate, agro-ecosystem dynamics and human management at farm to regional level, assessment studies of the impacts of climate change on agriculture have involved the use of computer simulations that link climate predictions of general circulation models (GCMs) together with crop models and land management decision tools . (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. J Met Soc Jpn 81:169177. 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. Int J Climatol 24:13451358. 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 .

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. Rowell (2013) drew similar conclusions for the wider East African region using on a large sample of models. (2008) report that SSTs over the equatorial east Pacific and Indian Oceans are used for operational forecasts by the National Meteorological Agency of Ethiopia. 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. 1). 9. Anouk is a travel writer, editor, and agent raised in Malawi and Kenya with more than 15 years of experience working in the African travel industry. Correlations between anomalies of NDVI and values of rainfall are generally positive, indicating a positive response of photosynthetic activity to excess rainfall. ,Sitemap,Sitemap, barney martin wife This data provides monthly means of SSTs for the period 1870 to the present day.

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]. 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. 1999; Behera and Yamagata 2003; Black et al. 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. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. 0000066139 00000 n Dire Dawa is also more arid, with most of the rain falling during the short rainy season (March to April) and the long rainy season (July to September). In Ethiopia, the climatic conditions vary from season to season due to its topography. Poverty . 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 . doi:10.1175/1520-0442(2003)016, Saji NH, Goswami BN, Vinayachandran PN et al (1999) A dipole mode in the tropical Indian Ocean. The representation of these teleconnections in the HadGEM2 and HadGEM3-GA3.0 coupled climate models shows mixed skill. Reasons for this discrepancy are unclear. Clim Dyn 37:121131. The CAT rates Ethiopia's policies and action as "1.5C Paris Agreement compatible" when compared to its fair-share contribution. Basic climatic parameters such as temperature, rainfall, relative humidity, wind, evapotranspiration, and aridity are considered and their spatial distribution is analyzed. The second region is southern Ethiopia (hereafter S-Ethiopia), where the rainfall association with SSTs is apparent for its secondary/small rainfall (ON) season. 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. As shown in Sect. 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). 2009b). 2011).

Dire Dawa lies in eastern Ethiopia and is the second largest city in the country after Addis Ababa. In Ethiopia, rainfall and temperature change and variability are expected to have adverse impacts on agriculture and food security [10]. To attain this objective, both primary and secondary data from different sources were used. The "1.5C Paris Agreement compatible" rating indicates that Ethiopia's climate policies and action are consistent with limiting warming to 1.5C. Int J Climatol 21:9731005. Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. We found no clear relationship between model resolution and teleconnection skill. Introduction. This interactive shows the extent of the killing of lodgepole pine trees in western Canada. In: Proceedings of First Tech. 2011). 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 . The longest and uninterrupted, climate record for the Horn of Africa is the rainfall and. 0000017119 00000 n Rainfall in Ethiopia shows large variations across time and space, due to the complex topography and varying latitude of the country (Gamachu 1988). body #site input[type="submit"] { Reduction in rainfall (11%) and streamflow (42%) were found after changing points . 2009a, b). (2009b). 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. Department of Geography and Environmental Studies, Addis Ababa University, P.O. Model using the A1B scenario Meteorol Mag, Segele ZT, Lamb PJ ( )! The main findings of this study are summarised as follows. 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. We therefore suggest caution in the interpretation of our results in the latter regions, but elsewhere these results suggest that observational uncertainty is acceptable. Kathril, Aspect Warper Rules, The empirical analysis also confirmed that the basin losses a total of about 89.6 Mt of soil annually. We identify three seasons (MarchMay, MAM; JulySeptember, JAS; and OctoberNovember, ON), which are similar to those defined by climatological rainfall totals.

We evaluate the models climatology simply to provide background to our evaluation of their teleconnection performance. Time and Date. 3.2 and 3.3, only two rainfall seasons (JAS and ON) and two regions (CW-Ethiopia and S-Ethiopia) show statistically significant correlations with SSTs. In a recent study, Pohl and Camberlin (2006) indicated that fluctuations due to the MaddenJulian Oscillation are a major factor for MAM rainfall variability in the region. 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. A quasi-objective method is employed to define coherent seasons and regions of SST-rainfall teleconnections for Ethiopia. J Climate 26:53975418. Section4.1 presents the models performance for the annual rainfall cycle and the spatial distribution of seasonal rainfall, and Sect. 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. (2004) and Segele et al. 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. ]OB_ku.toi3~>[_qsYz-]KeeSYJlE@kAo[0hha67;i0{=~^{:=B& lB& lB& lB& lB& lB& l (1997).

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. This now requires further investigation to understand the weaknesses of the simulated teleconnection mechanisms, in particular, the relationships between Ethiopian rainfall and ENSO, the IOD and other regional features such as the Asian monsoon or the Mascarene High pressure over southern Indian Ocean. 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. Ethiopia has a high central plateau that varies from 1,290 to 3,000 m (4,232 to 9,843 ft) above sea level, with the highest mountain reaching 4,533 .

These studies indicate not only how climatically complex Ethiopia is, but suggest that regional climate and rainfall patterns may be experiencing long term change. 3.2 and 3.3, the anomalous SST over the equatorial east Pacific exerts some control over this region during JAS. Throughout the year, 1,160 mm (46 in) of rain fall, with a maximum from June to September, which is the only remarkably rainy period. 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.

Whole territory of Ethiopia is located in equatorial and subequatorial climate zones however altitude variety brings some features to weather conditions of the country. The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. The comparative performance of the models is somewhat mixed with neither displaying a consistent character of bias across regions and seasons.

Here, the definitions of Ethiopian rainfall seasons for Kiremt (over most part of the country except southern Ethiopia) and the small rainfall season (over southern Ethiopia) vary a little bit from what the Ethiopian National Meteorological Agency (NMA) recognizes with the omission here of June and September, respectively. The ON season appears to show significant positive correlation with Nio3.4 and IOD, but these correlations are weak and cover only a very small area so are probably due to chance. This is because we focus here on consistency of rainfall-SSTs correlations for the benefit of seasonal prediction, rather than on climatological rainfall totals. doi:10.2151/jmsj.81.169, Article 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. Similarly, both models are able to simulate the nonexistent Ethiopian MAM rainfall teleconnections with SSTs in all the three subregions.
