Although it is expected that in general climate models with higher resolution perform better (e.g. These are MarchMay, JulySeptember and OctoberNovember (Fig. 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. (2008) has used the SST anomalies from the Atlantic, Indian and Pacific Oceans to predict the MAM rainfall. 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. Behera SK, Yamagata T (2003) Influence of the Indian Ocean dipole on the Southern Oscillation. 4.4. Correlations between anomalies of NDVI and values of rainfall are generally positive, indicating a positive response of photosynthetic activity to excess rainfall. 2014 ). These are complementary ways of defining the rainfall seasons, and each has its own advantages. 0000001853 00000 n This refers to the natural internal component of atmospheric variability which differs between model simulations could cause some apparent variation in models skill. (Note that Rowell did not analyse MAM and JAS teleconnections to GHA.) The interannual rainfall variability in JAS for CW-Ethiopia and ON for S-Ethiopia, and the associated modes of SST (Nio3.4 and IOD), are shown in Fig. CLIMATE CHANGE AND ITS IMPACTS ON PEOPLE AND ECOSYSTEMS IN CENTRAL RIFT VALLEY, ETHIOPIA | Climate change impacts people's livelihoods climate change impacts ecosystem services how do people . 2011; Martin et al. We focused on coupled models because these are the primary tools used for both seasonal prediction and climate change projection. Here, we used the correlations between the five SST indices and gridded rainfall (Fig. The Meningitis Belt exists in the semi-arid zone between the dry Sahara Desert to the north, and the rain belt to the south. Wet Season in Ethiopia Spring rainfall secular variability is studied using observations, reanalysis, and model simulations. 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. #nav_row { In analyzing the results, the researchers found that we'll likely cross threshold for dangerous warming (+1.5 C) between 2027 and 2042. 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. Ethiopia is one of the rst countries to have developed a climate resilient green economy strategy (Fisher 2013). In the past, the This interactive shows the extent of the killing of lodgepole pine trees in western Canada. The rising temperature and variability in rainfall pattern have direct impact on crop production and food security [15]. The findings of our study, therefore, support this view. Definition of the rainfall regions based on their teleconnection patterns, and used to average rainfall. 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.

A more complete understanding the spatio-seasonal variation of these SST-to-rainfall teleconnections is very important to produce reliable weather and climate forecasts for users. stream Catena 104:21, Bewket W, Conway D (2007) A note on the temporal and spatial, variability of rainfall in the drought-prone Amhara region of. 0000126017 00000 n 2011a) and requires further examination. Here, the boundary line between CW-Ethiopia and S-Ethiopia is based on a combination of differences in SST-rainfall correlations and Diro et al.s (2008) climatological rainfall zones. Here are the average temperatures. The main objective of this section is to evaluate the performance of HadGEM2 and HadGEM3-GA3.0 in representing Ethiopian rainfall variability and its teleconnections with global SSTs. 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 . Korecha and Barnston 2007; Segele et al. Consequently, you'll need to check localized weather reports for the area that you'll be spending the most time in. 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. The interaction between human population and agricultural production is complex.Intense debates have been continued on population growth against agricultural development. Hence, this study provides a comprehensive view on the general patterns of the SST-to-rainfall teleconnections across both time and space for Ethiopia.

The left-hand panels show the observed mean rainfall (CRU3.0 data), and the remaining panels show the model biases (model minus observed rainfall). Only the IOD to S-Ethiopia ON rainfall teleconnection in the HadGEM2 and HadGEM3-GA3.0 (N96) models is represented quite well. Historic year 1984 km area ) Reg Plann 1 ( 4 ):65, Nations. Clim Dyn 37:121131. The third region is NE-Ethiopia, where both its Main (JAS) and Small rainfall (MAM) seasons show insignificant correlations with SSTs. 3.2, the SST-to-rainfall teleconnections for Ethiopia not only vary seasonally, but also spatially. 2011a). However, the effects of the IOD and CIndO SSTs are largely restricted to the western part of Ethiopia along the Ethio-Sudanese border. Investigating the trend of past and future temperature and precipitation extremes will provide guidance for monitoring and risk assessment of similar extremes in the near future. There is a need to understand the ecological dynamics of these climate impacts, to identify hotspots of vulnerability and resilience and to identify management interventions that may assist biosphere resilience to climate change. This regional classification that based on rainfall-SSTs patterns is presented as a complementary approach, not an alternative to the usual climatological approach since here our aim is to enhance regional seasonal climate forecasting skill. 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. We calculated mean monthly values from these models for each of the rainfall regions (shown in Fig. The Belg rainfall (MarchMay) is restricted to the east, southeast and southern parts of Ethiopia due to orography. (2011a) also reported the presence of some correlation between SSTs over the southern Atlantic Ocean and Gulf of Guinea and Ethiopian JuneSeptember rainfall. doi:10.1038/385516a0, Cheung WH, Senay G, Singh A (2008) Trends and spatial distribution of annual and seasonal rainfall in Ethiopia. 2015: Journal of Climate, 28(23), DOI: 10.1175/JCLI-D-15-0216.1.

In late 2012, we began transitioning to an operational status, which we completed in early 2013. 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.

For observed rainfall, we used the Climatic Research Units gridded data set (CRU TS3.1) described by Harris et al. 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 . A few of these studies, such as Segele and Lamb (2005); Segele et al. 2003; Marchant et al. Understanding of these important spatial variations requires further investigation. Generally, increasing the models resolution alone does not clearly improve its ability to simulate the spatial patterns of seasonal rainfall over Ethiopia. #branding .content-pad { experienced drought conditions in the last decade.

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. (p = 0.008), monthly maximum temperature (p = 0.013) and monthly total rainfall (p = 0.040), at one month lagged effect, were significant meteorological factors for transmission of malaria in the study area. 1) long cycle crop growing area of the country. The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. 0000004484 00000 n In this study, the objective is to understand the spatial and seasonal patterns of teleconnections between Ethiopian rainfall variability and global SSTs using observed rainfall and SST data. MAD and DPR were supported by U.K. Department for International Development (DFID)-Met Office Hadley Centre Climate Science Research Partnership (CSRP) program, Agreement Number: L0830. Both models poorly represent the statistically significant teleconnections, except that HadGEM2 and the low resolution (N96) version of HadGEM3-GA3.0 better represent the association between the IOD and S-Ethiopian ON rainfall.

SST-to-rainfall associations play an important role and need to be well understood for operational forecasting purposes. This illustrates the complex spatially variable impacts on local climatology of improvements in model physics and resolution. Currently, the demand for climate model data is growing due to this increasing interest in climate information (Hewitt et al. Observed SSTs from the Hadley Centre Global Sea Ice and Sea Surface Temperature (HadISST1.1) data set at 11 resolution, described by Rayner et al. 0 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 . 0000004710 00000 n The sensitivity of vector borne diseases like malaria to climate continues to raise considerable concern over the implications of climate change on future disease dynamics. 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. Towards Ethiopia's borders, elevations decrease and temperatures rise accordingly. Bjp Banner Maker, Apart from this, both models are able to capture the low rainfall amounts observed over the southern and southeastern parts of Ethiopia. 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. J Climate 22:33963421. Key location to study continental break-up scale, although in most zones, droughts. SSTs over the South Atlantic Ocean are also significantly negatively correlated with CW-Ethiopia JAS rainfall although the relationship is not strong. 0000011918 00000 n 0000127516 00000 n The effect of ENSO on the onset and length of the Ethiopian Kiremt (JuneSeptember) season has also been reported (Segele and Lamb 2005). 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. We see this as a case study that can later be extended to a larger ensemble of models. {gU6HJk ~ExmC4`Pg?< Only Diro et al.

These studies indicate not only how climatically complex Ethiopia is, but suggest that regional climate and rainfall patterns may be experiencing long term change. Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of Africa.It shares borders with Eritrea and Djibouti to the north, Somaliland to the northeast, Somalia to the east, Kenya to the south, South Sudan to the west and Sudan to the northwest.Ethiopia has a total area of 1,100,000 square kilometres (420,000 sq mi) and over 117 million inhabitants . In the United States, the strongest change in rainfall is in the southeast, the region closest to the pool of warm Pacific water. We provide an overview of the seasonality and spatial variability of these teleconnections across Ethiopia. 2011). However, in reality, each area has its own rainfall patterns. Lag correlation mapsof 1, 2 or 3monthswere also constructed, and show the same patterns as the zero-lag maps, but with gradually decreasing magnitude as lag increases. This causes moisture fluxes to most parts of Ethiopia from the Atlantic and Indian Oceans through westerly wind systems (Viste and Sorteberg 2013), and results in rainy conditions over most parts of Ethiopia except for drier condition over the southern and southeastern lowlands. Amasco Ceiling Fan Review, 2009). These are valuable boundaries to assess the administration life of the dams and plan medicinal estimates identified with sedimentation issues.
