do we have dynamics in temperature and rainfall in ethiopia

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. Reg Environ Change 14:799810. 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. Both climate variability and change have been occurring in Ethiopia. J Climate 25:84228443. H\@}&:TA8s1)C~'=0jRTo];pqtkx:c6;]tt6j&mwv/W}'^b7[.

The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. Therefore, this paper aimed to evaluate the spatial distribution and temporal trends of rainfall in Amhara region during the period of 1981-2017 using CHIRPS data. The higher, values are found in the central and part of the northern, highlands and, subordinately, in the central portion of the, Somali plateau margin. padding: 10px 0px 21px; Your email address will not be published.

Malaria has been Ethiopia's predominant communicable disease for decades. 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 . U&5vhOb$3$EM&K7 Precipitation here is about 1058 mm | 41.7 inch per year. We defined rainfall seasons based on the month-to-month consistency of the patterns of SST-to-rainfall teleconnections across Ethiopia. conditions results in ample thermal differences (Fig. (2011); and two resolutions of HadGEM3-GA3.0 (Hadley Centre Global Environment Model version 3 with Global Atmosphere version 3.0) as described in Hewitt et al. Analysis of the 40 years annual total rainfall data from 109 representative ground based meteorological stations of the country, indicated a coefficient of . minimum temperatures are for the same points and girds, but cover the period 19812011. These are MarchMay (MAM), JulySeptember (JAS) and OctoberNovember (ON). Similarly, previous studies (Hastenrath et al. 0000056870 00000 n The representation of these teleconnections in the HadGEM2 and HadGEM3-GA3.0 coupled climate models shows mixed skill. A quasi-objective method was employed to define coherent seasons and regions of SST-rainfall teleconnections for Ethiopia. The study used 4 km 4 Expand Prediction of bimodal monsoonal rainfall in the central dry zone of Myanmar using teleconnections with global sea surface temperatures Whereas goats were having positive relationship (r = 0.345, P < 0.001) (Tables 2 and 3). Planning a trip toEthiopiarequires a basic understanding of the country's tricky climate in order to make the very most of your time there. Long-Run Coefficients and Short-Run Dynamics. 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. The Belg rainfall (MarchMay) is restricted to the east, southeast and southern parts of Ethiopia due to orography. sists mainly of alpine prairie and arboreal species is absent. 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. Mon Weather Rev 131:7494. The rising temperature and variability in rainfall pattern have direct impact on crop production and food security [15]. This study suggests the need for an integrated assessment and enhancement of adaptive capacity with all its components rather than focusing only on asset possession as an indicator of adaptive capacity. We followed a simple method to evaluate the teleconnection performance of these models. 0000126017 00000 n The rainfall over this region is positively related with Nio3.4 and IOD, and is statistically significant. this brief report, drawing from a multi-year effort by the u.s. agency for international development (usaid) famine early warning systems network (fews net), examines recent trends in march-june, june-september, and march-september rainfall and temperature, identifying significant reductions in rainfall and increases in temperature over time in Low Temp: 48 F. The Climate Resilient Green Economy (CRGE) strategy must, therefore, make greater efforts to embed young people's livelihoods and wellbeing in the strategy. doi:10.1002/met.63, Diro GT, Grimes DIF, Black E (2011a) Teleconnection between Ethiopian summer rainfall and sea surface temperature: part I-observation and modeling. } 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. Rainfall is the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia (Conway 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. 0000002033 00000 n 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 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. 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. In: Proceedings of First Tech. Similarly, Tsidu (2012) evaluated the spatio-temporal reliability of CRU and other gridded data sets using rainfall records of 233 gauge stations over Ethiopia for the 19782007, and found statistically significant correlations of 0.810.95 over central and northern Ethiopia, 0.660.80 over western and southeastern Ethiopia, and 0.520.65 over other parts of the country.

Currently, the demand for climate model data is growing due to this increasing interest in climate information (Hewitt et al. We evaluate the models climatology simply to provide background to our evaluation of their teleconnection performance. aspects of climate change in Ethiopia to the phys-, iographic which! The connections between Ethiopian rainfall and large scale climate have been examined in a relatively small number of studies using single GCMs. We also note that HadGEM3-GA3.0 is a climate model that was under continuous improvement (Hewitt et al. Meteorol Atmos Phys 89:153180. Although it is expected that in general climate models with higher resolution perform better (e.g. 3.2 and 3.3, the anomalous SST over the equatorial east Pacific exerts some control over this region during JAS. J Climate 26:53975418. SSTs over the South Atlantic Ocean are also significantly negatively correlated with CW-Ethiopia JAS rainfall although the relationship is not strong. The interaction between human population and agricultural production is complex.Intense debates have been continued on population growth against agricultural development. Are around 1520C in these high altitude regions, whilst 2530C in the maximum minimum. ]OB_ku.toi3~>[_qsYz-]KeeSYJlE@kAo[0hha67;i0{=~^{:=B& lB& lB& lB& lB& lB& l Generally, the best time to visit Ethiopia is between November and February when clear, sunny days bring regular average temperatures of 25C (77F). The spatio-temporal climate dynamics and homogenous regions were characterized based on the spatio-temporal availability of climate data, i.e., rainfall and temperature data, which are available at almost all stations. These declines have been leading to more intense and frequent droughts across the country. 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. The driest months in Ethiopia are typically November and February. startxref 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. Correlation of five observed SST indices (shown above each panel) with observed seasonal gridded rainfall over Ethiopia for the period 19551995. 4.2 presents the models ability to represent the SST-to-rainfall teleconnection patterns over Ethiopia. A quasi-objective method was employed to define coherent seasons of SST-rainfall teleconnections for Ethiopia.
