Following the catastrophic malaria outbreak in 2003-2004, the Federal Ministry of Health (FMoH) took drastic public health actions to lower the burden of malaria. The rainfall over this region is positively related with Nio3.4 and IOD, and is statistically significant. 2011; Martin et al. All zones experienced drought at the annual scale, although in most zones, previous droughts were more extreme.

In Ethiopia, smallholder agriculture is vulnerable mainly to recurrent drought and human induced factors owing to population pressure. Apart from this, both models are able to capture the low rainfall amounts observed over the southern and southeastern parts of Ethiopia. For our study, we considered the rainfall data for the period 19551995 to maintain the quality of data because in the early twentieth century some stations had not been established, and from the end of the twentieth century some stations had ceased reporting or their data was not readily available. Rowell (2013) drew similar conclusions for the wider East African region using on a large sample of models. 3a, b (and also with those not shown). Thanks to its location on an elevated plateau, Addis Ababa enjoys a pleasantly cool climate that can be a welcome respite for travelers arriving from the country's desert areas. Coldest winter ( January to March ) was in 1984 with an temperature. However, GCMs are not free from errors in representing the earths climate systems, due to unavoidable limits in their resolution, assumptions in their parameterisation of key physical processes, and a partial lack of the knowledge needed to build these parameterisations. color: #FFFFFF; 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. 2014a, b).

As shown in Sects. rainfall on the basis of gridded data and interpolation. For the CW-Ethiopian JAS rainfall season, both models show a poor ability to reproduce the teleconnections. Climate Data Online (CDO) provides free access to NCDC's archive of global historical weather and climate data in addition to station history information. The physical mechanisms of these teleconnections are found in many previous studies (Black 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. 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. Regional climate model projections of rainfall from U.S. landfalling tropical cyclones. - 81.89.100.63. Here are the average temperatures. 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. 9. Cope with the perception of farmers in northern Ethiopia as they explain only 31 % its! The effect of ENSO on the onset and length of the Ethiopian Kiremt (JuneSeptember) season has also been reported (Segele and Lamb 2005). 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.

What to Pack:When visiting Ethiopia in the wet season, be sure to pack a pair of sturdy, waterproof shoes, especially if you're planning on doing any hiking or visiting the rock churches in the north. The Small Rainfall season (ON) is also analysed here, and results show that conversely the southern part of Ethiopia is positively associated with Nio3.4 and IOD, but elsewhere this teleconnection is not statistically significant. The best time to visit Addis is duringthe dry season (November to February). Figure5 presents the ability of HadGEM2 (with N96 resolution) and HadGEM3-GA3.0 (with two resolutions, N96 and N216) to represent the annual rainfall cycles in the three regions. http://clearinghouse5.fgdc.gov/enraemed/NMSA. 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. 2009a). We find there are three distinct rainfall seasons in Ethiopia with their specific SST-to-rainfall teleconnection patterns.

Figure3a shows the correlation patterns of global SSTs against the average rainfall for CW-Ethiopia for the JAS 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. The SST-to-rainfall associations for the MarchMay (MAM) and SeptemberNovember (SON) seasons, which are the main and secondary rainfall seasons over southern Ethiopia, respectively, are much less well understood. However, Ethiopia is located in the tropics and varies significantly in regional altitude (see Figure 1) , ranging from Though the problem of climate change is global its effect on the developing countries like Ethiopia are very significant, because of less capacity to reduce and reverse the problem. conditions results in ample thermal differences (Fig. and the rain belt to the south. The problem of malaria vectors shifting from their traditional locations to invade new zones is of important concern. Diverse rainfall and temperature patterns are largely the result of Ethiopia's location in Africa's tropical zone and the country's varied topography. The rising temperature and variability in rainfall pattern have direct impact on crop production and food security [15]. Compared with HadGEM2, the HadGEM3-GA3.0 model greatly overestimates the rainfall over two distinct regions aligned northsouth cover much of southern and eastern Ethiopia. Conf. The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. We identify three seasons (MarchMay, MAM; JulySeptember, JAS; and OctoberNovember, ON), which are similar to those defined by climatological rainfall totals. 0000000016 00000 n 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.

Teleconnections between Ethiopian rainfall variability and global SSTs: observations and methods for model evaluation. There will be ups and downs even if we are in the middle of a warming trend. Temperature in Ethiopia averaged 22.88 celsius from 1901 until 2021, reaching an all time high of 23.95 celsius in 2009 and a record low of 22.14 celsius in 1967. 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. In late 2012, we began transitioning to an operational status, which we completed in early 2013. experienced drought conditions in the last decade. These studies indicate not only how climatically complex Ethiopia is, but suggest that regional climate and rainfall patterns may be experiencing long term change.

Increased evaporation will result in more frequent and intense storms, but will also contribute to drying over some land areas. (1997). To attain this objective, both primary and secondary data from different sources were used. The warming trends in the maximum and minimum temperatures for Basona Werana and Efratana Gidim, respectively, are statistically significant at p = .05 and p = .01 levels. doi:10.5194/gmd-4-1051-2011, Conway D, Lisa E, Schipper F (2011) Adaptation to climate change in Africa: challenges and opportunities identified from Ethiopia. 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 . 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. doi:10.1007/s00382-010-0896-x, Enfield DB, Mestas-Nunez AM, Mayer DA, Cid-Serrano L (1999) How ubiquitous is the dipole relationship in tropical Atlantic sea surface temperature?

(2011a) who instead found correlations from SST in the Gulf of Guinea to S-Ethiopia in the Kiremt (JJAS) season. 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 views expressed are not necessarily those of DFID. 1.1). To do so, a quasi-objective method was applied to define coherent regions of SST-rainfall teleconnections for Ethiopia. 0000001997 00000 n 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 .

Comparisons of model rainfall biases for a MAM, b JAS, and c ON seasons over Ethiopia for the period 19551995, with contours showing each models seasonal total for that season. 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. 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. Climate changes directly and indirectly affect the growth and productivity of forests through changes in temperature, rainfall, weather, and other factors. 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). 0000066139 00000 n We correlated each of the regional model rainfall time series with the global gridded SSTs for each model and season.

The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. volume129,pages 173186 (2017)Cite this article. 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 the main rainfall season in southern Ethiopia and the secondary rainfall season over the central and northeastern Ethiopia (Diro et al. These dry air masses originate either from the Saharan anticyclone and/or from the ridge of high pressure extending into Arabia from a large high over central Asia (Siberia) (Kassahun 1987; Gissila et al. 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. It has also evaluated the ability of the HadGEM2 and HadGEM3-GA3.0 coupled atmosphereocean Global Circulation Models (AOGCMs) to simulate seasonal SST teleconnections to rainfall at the subnational scale, using Ethiopia and these two models as a case study. In addition to this, the high resolution (N216) HadGEM3-GA3.0 model has an early start and excessive rain before the wet season. Neither cool nor Warm. Rate is 5.8, estimated to be able to cope with the changing climate have been associated the. Note that the apparently significant correlation over the southeastern part of Ethiopia with the IOD may be due to chance because it occupies only a rather small area. No correlation was found for the MAM and JAS seasons. In the past, the The spatial and temporal distribution of climatological rainfall in Ethiopia is largely controlled by the annual northsouth migration of the Inter Tropical Convergence Zone (ITCZ) (Kassahun 1987) over Ethiopias complex topography. Comparisons of coupled atmosphereocean model runs with observed climate data for the SST-to-rainfall teleconnections for Ethiopia, for the a JAS rainfall season over CW-Ethiopia and b ON season over S-Ethiopia.
