do we have dynamics in temperature and rainfall in ethiopia

Reg Environ Change 14:799810. Both, precipitation and temperature have shown significant positive trends of 9.7 10 2 /yr and 2.7 10 2 /yr respectively over the study region from 1982 to 2015. For the, indicates a mean annual temperature increase of 0.28, hot days and a decrease of cold days. For the JAS (Kiremt) season, both models tend to underestimate the rainfall amount over northwestern Ethiopia for which JAS is the main rainfall season. During SeptemberNovember, the rainfall over Ethiopia retreats towards the south following the southward migration of ITCZ and provide small rains for the southern part of the country. Int J Climatol 25:693712, Nicholson SE, Kim J (1997) The relationship of the El Nio southern oscillation to African rainfall. 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. doi:10.2151/jmsj.81.169, Article 2006) are known to affect the equatorial east African Short rains, and here we show there are also significant correlations with southern Ethiopia. Section4.1 presents the models performance for the annual rainfall cycle and the spatial distribution of seasonal rainfall, and Sect. In late 2012, we began transitioning to an operational status, which we completed in early 2013. Diverse rainfall and temperature patterns are largely the result of Ethiopia's location in Africa's tropical zone and the country's varied topography. 0000056870 00000 n The problem of malaria vectors shifting from their traditional locations to invade new zones is of important concern. @'d\0KxI(=|` U&5vhOb$3$EM&K7 GCMs are also acknowledged for their potential to be able to respond to unusual SST anomaly patterns and any consequential responses in teleconnections. 0000088798 00000 n Bjp Banner Maker, Malaria has been Ethiopia's predominant communicable disease for decades.

Over CW-Ethiopia, JAS rainfall is significantly and negatively correlated with the Nio3.4, CIndO and IOD modes of SST variability. 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. Model using the A1B scenario Meteorol Mag, Segele ZT, Lamb PJ ( )! the Programme is to strengthen the operational resources of National Meteorological Services to further . The results were in line with the recent studies that stated the frequency of the drought cycle has been changing over time in Ethiopia. We find there are three distinct rainfall seasons in Ethiopia with their specific SST-to-rainfall teleconnection patterns. Correlation magnitudes of 0.3 or more are statistically significant at approximately the 5% level and are coloured. trailer 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. 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. 2011; Hewitt et al. doi:10.1007/s00382-010-0837-8, Diro GT, Grimes DIF, Black E (2011b) Teleconnections between Ethiopian summer rainfall and sea surface temperature: part II.

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. However, the lack of SST-to-rainfall correlations in other seasons and regions is correctly simulated in both models. DYgw^.eJ[:e2W:s0>Ea2hal^t#"MG'cXuYCz[M'*.

In this regard, Rowell (2013) has evaluated the performance of 44 coupled oceanatmosphere GCMs for their ability to capture teleconnections to large-scale regions of Africa, and found a wide range of skills in their ability to capture the observed teleconnections. 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. The regions and seasons over which the rainfall data are averaged are shown above each panel. These rivers descend from the mountains in great falls, and like the other Ethiopian streams are unnavigable in their upper courses. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. Temperature, rainfall, and elevation were the major determinants of malaria incidence in the study area.

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. Mon Weather Rev 131:7494. The main findings of this study are summarised as follows. (2006). The data period used for this purpose was 41years (19551995). Nature 385:516518. It also interacts with other pressures on ecosystems, including degradation, defaunation and fragmentation. 2015: Journal of Climate, 28(23), DOI: 10.1175/JCLI-D-15-0216.1. However, a comparison with Rowells results shows the mixed skill found here for the Small Rains in subregions of Ethiopia is inferior to the at least reasonable skill found for the much larger Greater Horn of Africa (GHA) region. Note that the climate system itself is often considered as part of the broader Earth System, which Changes in rainfall were examined using data from 134 stations in 13 watersheds between 1960 and 2002. The amount of rainfall varies spatially within the country and within different regions in the country. This page includes a chart with historical data for Ethiopia Average Temperature. Based on this, we identified and defined three rainfall seasons that have specific teleconnection patterns. Beginning in the 1960s, GFDL scientists developed the first coupled ocean-atmosphere general circulation climate model, and have continued to pioneer improvements and advances in a growing modeling community. the spatio-temporal dynamics of rainfall and temperature in the past (1988-2017) and projected periods of 2030 and 2050 under two Representative Concentration Pathways (RCP4.5 and RCP8.5) .

Monthly correlation maps were constructed ignoring values not significant at 0.5 level. 10 March 2021.DOI: 10.1038 . Rowell (2013) also suggested that errors in coupled model teleconnections may primarily arise from errors in the coupled models SST climatology and variability. The first type is composed of euritic nitosols and andosols and is found on portions of the Western and Eastern highlands. April 17, 2015. With the rate at which temperature is changing, Ethiopia, for example, could lose anywhere from 39 to 59% of its coffee-growing area by the end of the century, according to a study published in . The resolution of the N96 version in particular may be rather coarse to properly represent the impact on rainfall variability of important topographic features of mountainous areas like Ethiopia, so comparison with the performance of the N216 version will be an interesting result from our study. This section focuses on these two seasons and regions.

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). Then, these correlation maps were visually compared against the observed teleconnection plots shown in Fig. 0000002033 00000 n } 2009b). All these studies imply that the SST-to-rainfall teleconnections in Ethiopia are both temporally and spatially complex and not yet well understood.

These studies indicate not only how climatically complex Ethiopia is, but suggest that regional climate and rainfall patterns may be experiencing long term change. If you're planning on visiting the Omo River Region, be prepared for very hot temperatures. Segele et al. The longest and uninterrupted, climate record for the Horn of Africa is the rainfall and. 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. The Northern part of . } Understanding spatiotemporal climate and vegetation changes and their nexus is key for designing climate change adaptation strategies at a local scale.

Over the Atlantic Ocean, we use the tropical Atlantic Dipole (TAD) that is the difference between a tropical North Atlantic average (5N25N and 15W55W) minus a tropical South Atlantic average (020S and 10W30W) as described in Enfield et al. Read our. J Climate 16:27352751. We can see different climatic conditions mostly three seasons say. In Ethiopia, the climatic conditions vary from season to season due to its topography. 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. 2.1 degrees more at 20.9 C for this three-month period patterns or.

The increment in minimum temperature is also more prominent in the 2080s and it is expected to rise by 4.75 C. We have ambitious plans for NOAA Climate.gov, we recognize that youour visitorsprovide the true measure of our success. We also identify three new regions (Central and western Ethiopia, CW-Ethiopia; Southern Ethiopia, S-Ethiopia; and Northeast Ethiopia, NE-Ethiopia) that are complementary to those previously defined here based on distinct SST-rainfall teleconnections that are useful when predicting interannual anomalies. 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. We produced maps of the local correlations from five SST indicesrepresenting the main tropical modes of variabilityto gridded monthly and seasonal rainfall over Ethiopia. 156 0 obj <> endobj Meteorol Atmos Phys 129, 173186 (2017). 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. As we described in Sects. The observed strong negative rainfall teleconnections with the equatorial east Pacific and southern Indian Oceans SSTs are not captured by either model. 2011). 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 . Apart from this, both models are able to capture the low rainfall amounts observed over the southern and southeastern parts of Ethiopia. . 0000000016 00000 n 0000004447 00000 n The SSTs indices considered over the Indian Ocean are the central Indian Ocean index (CIndO) average over (55E95E and 25S10N) as described in Rowell (2013), and the Indian Ocean Dipole (IOD) which is the average over (10S10N and 50E70E) minus the average over (10S0 and 90E110E) as described in Saji et al. Ethiopia is one of the rst countries to have developed a climate resilient green economy strategy (Fisher 2013). (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. 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. Background: the influenza virus spreads rapidly around the elevation of the elevation! Towards Ethiopia's borders, elevations decrease and temperatures rise accordingly. 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. As the .
