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. The average daily mean is around 78 degrees Fahrenheit (25 degrees Celsius), but average highs for the hottest month, June, exceed 95 degrees Fahrenheit (35 degrees Celsius). The Geophysical Fluid Dynamics Laboratory has been one of the world leaders in climate modeling and simulation for the past 50 years. Int J Climatol 29:10751100. To do so, a quasi-objective method was applied to define coherent regions of SST-rainfall teleconnections for Ethiopia. Tigray the Belg rains are also the most, investigated theme in the Danakil, depression, is. The climate is warm and temperate in Lemmi. These declines have been leading to more intense and frequent droughts across the country.

Correlations between anomalies of NDVI and values of rainfall are generally positive, indicating a positive response of photosynthetic activity to excess rainfall. Located in the north of the country, Mekele is the capital of the Tigray region. Int J Climatol 17:117135. Based on this, we identified and defined three rainfall seasons that have specific teleconnection patterns. 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). 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. Correlation magnitudes of 0.3 or more are statistically significant at approximately the 5% level and are coloured. 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. A regression model of previous monthly rainfall at lag 0 and Lag 2, monthly mean maximum temperature at lag 2 and Lag 3, and monthly mean minimum temperature at lag 3 were found as the best prediction model for monthly malaria incidence. In addition, elevated levels of carbon dioxide have an effect on plant growth. doi:10.1002/joc.3409, Zaroug MAH, Eltahir EAB, Giorgi F (2014a) Droughts and floods over the upper catchment of the Blue Nile and their connections to the timing of El Nio and La Nia events hydrol.

Global climate change remains one of the biggest environmental threats to human welfare over the coming century. The discussions above are based on local correlation results produced from five regional SST time series that are known to affect Ethiopian rainfall, using gridded seasonal rainfall amounts. Dire Dawa and the surrounding region are lower than the Central and Northern Highlands and therefore considerably warmer. Basic climatic parameters such as temperature, rainfall, relative humidity, wind, evapotranspiration, and aridity are considered and their spatial distribution is analyzed. Also, SST-to-rainfall correlations for other season-regions, and specifically for MAM in all regions, are found to be negligible. (Murakami, H., et al.)

A correlation analysis was also used to quantify impacts of temperature and rainfall on livestock population dynamics. The regional classifications by previous studies (e.g. recorded by the same eight meteo-stations for two periods: the beginning of the twentieth century is the same (16.4, much larger daily excursion, i.e., 15.2 versus 13.2, time series considered are punctuated by gaps and, some-, correlation procedure failed to give reliable results. 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. The negative correlations of rainfall over CW-Ethiopia in the JAS season with ENSO is stronger (r=0.59) than with the IOD (r=0.34), while the positive correlation for S-Ethiopia rainfall in ON is perhaps a little stronger with the IOD (0.56) than with ENSO (0.45). 2003; Saji and Yamagata 2003; Marchant et al. doi:0.1111/j.1365-2028.2006.00707.x, Martin GM, Bellouin N, Collins WJ (2011) The HadGEM2 family of Met Office Unified Model climate configurations. 2011a).

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. 3b). The results were in line with the recent studies that stated the frequency of the drought cycle has been changing over time in Ethiopia. doi:10.2151/jmsj.81.169, Article We also note that HadGEM3-GA3.0 is a climate model that was under continuous improvement (Hewitt et al. Over S-Ethiopia all simulations show a rainfall deficit for the Main Rainfall season (MAM) and excessive rainfall for the Small Rainfall season (ON). 4. Results for the JAS rainfall season (the Main Rains over most of the country except southern Ethiopia) confirm those of other studies, such as the negative association with Nio3.4. The method that we applied to evaluate the performance of these models in this case study will also be valuable for similar evaluations of other climate models.

Whereas goats were having positive relationship (r = 0.345, P < 0.001) (Tables 2 and 3). La Nia is the build up of cool waters in the equatorial . Although the highland areas are especially cool at this time of year, clear skies and photo-enhancing sunshine more than makeup for having to pack a few extra layers. A few of these studies, such as Segele and Lamb (2005); Segele et al. The findings of our study, therefore, support this view. In Ethiopia, malaria is seasonal and unstable, causing frequent epidemics. This dataset provides monthly mean precipitation totals at 0.5 spatial resolution for the period 1901 to the present day. All zones experienced drought at the annual scale, although in most zones, previous droughts were more extreme. 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. Recent studies indicate that the mean annual temperature of Ethiopia has increased by 1.3 C between 1960 and 2006, at an average rate of 0.28 C per decade and by 0.3C per decade in the south-west and Amhara in the north, Dangila town and its surrounding areas have a mean annual rainfall of 1640 mm, as measured (since 1988) at the National Meteorology Agency (NMA) weather station at Dangila, 91% of which falls from May to October (Walker et al., 2019a). (2014). 2015: Journal of Climate, 28(23), DOI: 10.1175/JCLI-D-15-0216.1. In contrast, the pattern of correlations for September is quite different, and that for December is statistically insignificant. 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. 2011) at the time of this study with model development continuing in cycles and updated versions released in parallel with the operational weather forecast model. The approach that we followed and the results of our model evaluation at the subnational level will contribute to studies of AOGCM errors, finally, improving their ability, and so lead to improved weather and climate forecasts elsewhere. For the S-Ethiopian ON rainfall season, the models show a mix of skills. 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. No correlation was found for the MAM and JAS seasons. A short lead time by annual PET values less than 0.65 are typical of drylands ( Thomas rainfall is ratio! In this study, the trend and variability of rainfall were compared with the perception of farmers in northern Ethiopia. However, such a study is lacking in many basins of Ethiopia.

Meteorology and Atmospheric Physics The annual and seasonal rainfall variability is between 50 and 80%, average temperature has been increasing at a rate of 0.37 C every ten years, and the maximum daily . We found that both the HadGEM2 and HadGEM3-GA3.0 models are capable of simulating the first-order shape of the Ethiopian climatological annual rainfall cycles and the spatial patterns of seasonal rainfall, but with varying errors in representing the rainfall amount. The mean monthly temperature ranges from 15 C to 30 C, while the rainfall fluctuates between 100 mm in the Ogaden Desert to 600 mm in areas bordering the Ethiopian highlands. J Climate 22:33963421.

In the far south, far west and far east of the country, averagedaily temperatures often exceed 85 degrees Fahrenheit (30 degrees Celsius). Therefore, in order to help policymakers and developers make more informed decisions, this study investigated the temporal dynamics of rainfall and its spatial distribution within Ethiopia. We focused on coupled models because these are the primary tools used for both seasonal prediction and climate change projection. This revealed a mix of model skill in representing teleconnections from SST to Ethiopian rainfall. 3b). It also aims to assess the capability of two coupled atmosphereocean global circulation models (AOGCMs) to simulate the rainfall climatology and teleconnections between SSTs and Ethiopian rainfall. Temperature, rainfall, and elevation were the major determinants of malaria incidence in the study area. xref
