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. Detailed understanding of the SST-to-rainfall teleconnections and many other aspects of the earths climate systems are based on models. In theory, Ethiopia'srainy seasonbegins in April and ends in September.

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. More winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century. Gissila et al. 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. 2011a) were correlated against the gridded Ethiopian rainfall, CRU TS3.1 (0.50.5). Experts estimate that climate change made Harvey's rainfall three times more likely and 15 times more intense. %%EOF 2014a, b). #nav_row { It can be seen in Fig. 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. Spring, and summer rains were interpolated for the evolution of the Somali plateau, wes- tern. 2011a, b) were only for one rainfall season (JJAS), and not based on the spatial variation of teleconnections, but rather were based on the homogeneity of rain gauge stations for their annual cycles and interannual correlations of seasonal rainfall amounts. Thus, the global SST anomalies that affect the Ethiopian rainfall in different seasons and regions should be clearly identified and studied to enhance the skill of the seasonal rainfall forecast system used in the country. 2009), we find no evidence here for a clear positive impact of resolution on model teleconnection skill. 2009a, b; Diro et al. and adaptation options in Ethiopia. 0000017119 00000 n SSTs over the South Atlantic Ocean are also significantly negatively correlated with CW-Ethiopia JAS rainfall although the relationship is not strong. There can be multiple MJO events within a season, and so the MJO is best described as intraseasonal tropical climate variability (i.e. The best time to visit Addis is duringthe dry season (November to February). Located in the north of the country, Mekele is the capital of the Tigray region. MRD 8:131138. Side Face Outline Drawing, [13] also confirmed the sensitivity of dry forests to the predicted changes in rainfall regimes across the dry tropical regions. 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. 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. In this study, the trend and variability of rainfall were compared with the perception of farmers in northern Ethiopia. The interaction between human population and agricultural production is complex.Intense debates have been continued on population growth against agricultural development. In Ethiopia, traveling from one area to another can mean shifting from 60 degrees Fahrenheit (15 degrees Celsius) to95 degrees Fahrenheit (35 degrees Celsius) in a matter of hours. Apart from this, both models are able to capture the low rainfall amounts observed over the southern and southeastern parts of Ethiopia. Int J Climatol 21:9731005. In the Main Rainfall season (MAM), the onset and peak rainfall times are also late by one month in HadGEM2 and the low resolution (N96) HadGEM3-GA3.0, whereas the high resolution (N216) version of HadGEM3-GA3.0 has less bias and an April peak as observed. The increment in minimum temperature is also more prominent in the 2080s and it is expected to rise by 4.75 C. J Climate 26:53975418. Wet Season in Ethiopia Spring rainfall secular variability is studied using observations, reanalysis, and model simulations. 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). (a) AEZ modelling methodology. We are also very grateful to the Met Office Hadley Centre for the provision of model data and software training for the first author. doi:10.1175/2008JCLI2537.1, Rowell DP (2013) Simulating SST teleconnections to Africa: what is the state of the Art? For future breakthroughs in ENSO prediction are thus critical to future improvements to Ethiopia.! 2009a, b; Diro et al. Hydrol Earth Syst Sci 18:12391249. <]/Prev 956938>> Over CW-Ethiopia, JAS rainfall is significantly and negatively correlated with the Nio3.4, CIndO and IOD modes of SST variability. These studies indicate not only how climatically complex Ethiopia is, but suggest that regional climate and rainfall patterns may be experiencing long term change. This atmospheric disturbance is distinct from ENSO, which once established, is associated with persistent features that last several seasons or longer over the Pacific Ocean basin. Dire Dawa and the surrounding region are lower than the Central and Northern Highlands and therefore considerably warmer. Eastern Ethiopia is typically warm and dry, while the Northern Highlands are cool and wet in season. Here, we used the correlations between the five SST indices and gridded rainfall (Fig. Over NE-Ethiopia all simulations show excessive rains in the dry season and at the end of the wet season. This rain gauge is located in, triangle at an elevation of 423 m s.l.m., but the driest, Asab, in Eritrea, with only 45 mm. Nature 385:516518. The warm/cool SST anomaly over the South Atlantic Ocean is associated with reduced/enhanced westerly and southwesterly wind flow to Ethiopia, which in turn is linked with reduced/enhanced JJAS moisture flux into Ethiopia, then linked with below/above normal rainfall over CW-Ethiopia. Only Diro et al.

Researchers say it can reduce prediction uncertainties by around 50%. The government of Ethiopia initiated a green economy policy to counter climate change and foster economic development such as the 2011 Climate Resilient Green Economy (CRGE). most important factors. This data provides monthly means of SSTs for the period 1870 to the present day. 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. doi:10.1002/(SICI)1097-0088(199702)172<117:AID-JOC84>3.0.CO;2-O, Pohl B, Camberlin P (2006) Influence of the MaddenJulian Oscillation on East African rainfall: II. minimum temperatures are for the same points and girds, but cover the period 19812011.

They found that we'll likely cross threshold for dangerous warming (+1.5 C) between 2027 and 2042. Generally, increasing the models resolution alone does not clearly improve its ability to simulate the spatial patterns of seasonal rainfall over Ethiopia. This page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. 2015: Journal of Climate, 28(23), DOI: 10.1175/JCLI-D-15-0216.1. 2006; Ummenhofer et al.

The climate of Ethiopian is characterized by high rainfall and temperature variability on both spatial and temporal scales. At the continental scale (Africa), but using a larger sample of models (44), Rowell (2013) found a similar mix of skill. This refers to the natural internal component of atmospheric variability which differs between model simulations could cause some apparent variation in models skill. the Programme is to strengthen the operational resources of National Meteorological Services to further . doi:10.1002/joc.3560, Kassahun B (1987) Weather systems over Ethiopia. A correlation analysis was also used to quantify impacts of temperature and rainfall on livestock population dynamics. Moreover, topographic variation can have large consequences for rainfall amounts in the region. 2004; Korecha and Barnston 2007; Diro et al.

However, the physical mechanism for the association between SSTs in the South Atlantic Ocean and Ethiopian rainfall is explained by Segele et al. 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. Mon Weather Rev 131:7494. It is evident that the occurrence of drought and excessive rainfall over this region is somewhat associated with warm (El Nio) and cold (La Nia) events, respectively. 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. Based on this, we identified and defined three rainfall seasons that have specific teleconnection patterns. 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 .

It usually occurs at altitudes < 2,000 m above sea level. 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. Segele et al. (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. The warm to cool, semi-humid zone: covers the mild highlands between 1,500 and 2,500 meters. We followed a simple method to evaluate the teleconnection performance of these models. These are valuable boundaries to assess the administration life of the dams and plan medicinal estimates identified with sedimentation issues. Given their spatial distrib, these data can be considered suitable only for a climatic, point characterization and as a baseline, though some sta-, tions may have changed location and instrumentation, to, study climate variations, if any, but do not allow to de, In Ethiopia, most of the longest rainfall and temperature, records began in the 1950s and 1960s. Over the last 35 years, our research team has recovered ice-core records of climatic and environmental variations from the polar regions and from low-latitude high-elevation ice fields from 16 . 0000008184 00000 n for time series and trend analysis, especially for rainfall. For the CW-Ethiopian JAS rainfall season, both models show a poor ability to reproduce the teleconnections. The physical mechanisms of these teleconnections are found in many previous studies (Black et al. Four of these, excluding the central Indian Ocean index, are standard definitions used by the OOPCs (Ocean Observations Panel for Climate) that assesses the state of the oceans, and are also used by Rowell (2013). 156 45 Are around 1520C in these high altitude regions, whilst 2530C in the maximum minimum. These data include quality controlled daily, monthly, seasonal, and yearly measurements of temperature, precipitation, wind, and degree days as well as radar data and 30-year Climate Normals.

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. 0000004484 00000 n 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. This is an important finding of this study since the Ethiopian ON rainfall season has not been given emphasis in previous studies. 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. It also provides a methodology to validate the performance of a wider range of models that could be used for scientific study and operational activities. Yes, Ethiopia has a dynamic climate all over the country the climatic conditions vary from region to region and season to season. 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.

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 . Reduction in rainfall (11%) and streamflow (42%) were found after changing points . Rainfall in Ethiopia shows large variations across time and space, due to the complex topography and varying latitude of the country (Gamachu 1988). 2004; Diro et al. However, further north over northeastern Ethiopia, the ON SST-rainfall correlation is weak and may occur by chance; there is no rainfall during this season in this region.
