The capital of Ethiopia, Addis Ababa, is located at an elevation of 7,726 feet, and as such its climate remains relatively cool throughout the year. The frequency of hot days and nights will substantially increase. It has observed an upward livelihood patterns but fluctuating over the study period. In Ethiopia, mean annual temperature has increased by 1.3°C between 1960 and 2006, an average rate of 0.28°C per decade. 9. changes in temperature and rainfall patterns are widely observed in many semi-arid parts of the developing world that are likely to become even hotter and dryer with time [2]. Even in the hottest months (March to May), average highs rarely exceed 77 degrees Fahrenheit (25 degrees Celsius). North eastern Ethiopia is one of the sensitive regions to climate variation particularly to temperature and rainfall changes. dynamics that initiate seasonal rains. of temperature and rainfall in lake Tana Sub-basin, Ethiopia Solomon Addisu*, ... taking into consideration of the dynamics of the poor and their livelihoods, it is clear to understand how they will be affected by climate change hazards, how they might respond with the resources they have, and how these conditions can be replicated and built upon for successful adaptation strategies. The study has aimed to reveal the livelihood dynamics of rural households in Ethiopia and their association with rainfall conditions and household socio-economic characteristics. 2015). Rainfall Temperature Ethiopia ABSTRACT Examining the spatiotemporal dynamics of meteorological variables in the context of changing climate, partic-ularly in countries where rainfed agriculture is predominant, is vital to assess climate-induced changes and suggest feasible adaptation strategies. This study investigates the temporal variability and trend of temperature and rainfall in Gelana sub-watershed, northern highlands of Ethiopia. The net variance in the number of monthly malaria outpatients caused by autoregression and seasonality varied among sites and ranged from 18 to 63% (mean = 38.6%), whereas 12–63% (mean = 36.1%) of variance is attributed to climate variability. J Earth Sci Clim . In Ethiopia, there are three seasons with four months each, classified based on climatological means of rainfall and temperature. Inter-annual variability of precipitation and rising trends of temperature has observed [3]. Therefore, this study attempts to investigate climate variability in terms of annual and seasonal rainfall fluctuations and monthly temperature trends, and more importantly focus on the analysis of spatiotemporal dynamics of seasonal meteorological droughts across agroecological zones in the rift valley lakes basin of Ethiopia. Hydrol Current Res 9: 293. doi: 10.4172/2157-7587.1000 293 4, 2020, pp. Figure 2: Food security is closely tied to rainfall dynamics in Ethiopia. The relationship between rainfall and atmospheric dynamics and ENSO is next analyzed , for each of the major regional rainfall indices identified in the previous section; namely, Kenya–Uganda and Ethiopia. The fine grid spacing (<6 km) is adequate to depict mesoscale topography (Goswami et al., 2012), which resolve areas of high and low elevation. 2019; Gebrechorkos et al. Mean annual temperatures are around 15‐20˚C in these high altitude regions, whilst 25‐30˚C in the lowlands. Ethiopia has three rainy seasons: June–September (kiremt), ... Future projections of temperature and rainfall exhibit a high degree of uncertainty, but most projections agree that: Mean annual temperature is projected to increase by between 1°–2°C by 2050. January is a moderately hot winter month in Addis Ababa, Ethiopia, with average temperature fluctuating between 9°C (48.2°F) and 23°C (73.4°F).In Addis Ababa, the average high-temperature is practically the same as in December - a moderately hot 23°C (73.4°F). Weather in January » The study employed a mixed methods approach, but overwhelmingly relied on gridded monthly rainfall and maximum and minimum temperature data at a resolution of 10 × 10 km. Singular value decomposition method is used to investigate the covariability between Ethiopian main rainy season [Kiremt, June to September (JJAS)] anomalies and the anomalous sea surface temperature (SST) in Indian Ocean based on precipitation and SST reanalysis datasets. The mean annual temperature is projected to increase by 1.1 to 3.1°C by the 2060s, and 1.5 to 5.1°C by the 2090s (McSweeney et al., 2007). 6: 320. doi: 10.4172/2157-7617.1000320. 11. Temperature in Ethiopia decreased to 21.97 celsius in December from 22.68 celsius in November of 2015. 1). Ethiopia is a large complex country, with complex patterns of rainfall and livelihoods (Livelihoods Integration Unit, 2010). 8, No. Results show that significant coupled modes of variability exist, with the first dominant coupled mode … Analysis of Rainfall and Temperature Trends and Variability in Semi-arid North-eastern Ethiopia. The Amboseli basin, a semi‐arid, open savannah area of southern Kenya, has experienced extensive changes in habitat since the early 1960's. Temperature in Ethiopia averaged 23.02 celsius from 1850 until 2015, reaching an all time high of 26.20 celsius in April of 2011 and a record low of 20.08 celsius in December of 1907. Thus, our hypothesis is that long term deforestation causes rainfall and temperature pattern change and even small scale remnant forests have a beneficial effect of rainfall and one of the recommended impact reducing strategies, therefore, is the protection and plantation of small forests. of rainfall and temperature over Lake Tana Basin, Ethiopia Achenafi Teklaya,*, Yihun T. Dileb, ... dynamics. Find the best time to go to Addis Ababa. However, rainfall is highly variable across the country, from season to January, like December, in Gondar, Ethiopia, is a moderately hot winter month, with average temperature fluctuating between 27.3°C (81.1°F) and 10.3°C (50.5°F).In January, the average high-temperature is essentially the same as in December - a still warm 27.3°C (81.1°F). We employ household panel data spanning 15 years to estimate the impact of weather shocks on consumption and poverty dynamics in rural Ethiopia, along with the effectiveness of household coping strategies in alleviating the impact of shocks. 2018).East African countries; Ethiopia, Kenya and Tanzania showed an increasing tendency in extreme temperature indices, and irregular rainfall patterns (Gebrechorkos et al. This study focused on detecting trends in in rainfall (1983-2013) and temperature (1981-2010) at annual, seasonal and monthly time scales for six weather stations in semi-arid north eastern Ethiopia. Weather in January » Average precipitation (rainfall, snow) in millimeter per month in Addis Ababa, Ethiopia displayed in a beautiful overview. 2012).Moreover, analyzing both inter-annual and intra-annual trends in rainfall offers intuitive information on the dynamics of soil moisture in rain-fed systems (Zhao et al. Change. in contributing to vulnerability . International Journal of Environmental Monitoring and Analysis. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. Figure 4: Map showing the estimated distribution of groundwater availability in Ethiopia . Ethiopian areas, affected by a continuous forest and woodland decline. Getachew Asmare, Mengiste Abate, Morphological Changes in the Lower Reach of Megech River, Lake Tana Basin, Ethiopia ... Jimmy Byakatonda, B P Parida, Piet K Kenabatho, D B Moalafhi, Analysis of rainfall and temperature time series to detect long-term climatic trends and variability over semi-arid Botswana, Journal of Earth System Science, 10.1007/s12040-018-0926-3, 127, 2, (2018). Higher temperature, exceeding 30 °C, is recorded in the northern and eastern parts of Ethiopia, western Kenya, and Tanzania. The impact of climate change has received a great deal of attention worldwide. The monthly rainfall data are for 132 points of 10 × 10 km grids reconstructed from weather stations and meteorological satellite observations, which cover the period between 1983 and 2013. Figure 3: Areas where lack of rain or erratic rain is considered to be a key factor . Seasonal rainfall in Ethiopia is driven mainly by the migration of the Inter‐Tropical Convergence Zone (ITCZ). Lowlands receive minimal rainfall, and people generally sup-port themselves by raising livestock. 2018). OMICS Internat ional: Publication Benefits & Features.   Throughout the year, temperatures drop quickly once the sun goes down, and frosty mornings are common. Vol. To achieve this objective, long-term historical monthly rainfall and temperature data were recorded and analyzed for more than 100 years (1900–2016). In Ethiopia, higher elevations receive more rainfall than low arid areas and support agricultural livelihoods and higher population densities (fig. 2014), particularly, East Africa (Haile et al. The western part of Ethiopia is the major source of the Blue Nile River Basin and higher rainfall is observed in this area compared to other parts of the region (see Fig. (ENSO) and Vegetation Dynamics in Gojjam, Ethiopia. This study evaluates recent spatiotemporal variability and trends in rainfall and temperature in the central highlands of Ethiopia by using monthly rainfall and temperature records. Northeast Ethiopia is a semi-arid region that exhibits high rainfall and temperature variability. Temperature, rainfall and humidity have been associated with the dynamics of malaria vector populations and, therefore, with spread of the disease. The rainy season is of great importance not only to Ethiopia but to the countries of the Nile valley, as the prosperity of the eastern Sudan and Egypt is largely dependent upon the rainfall. Especially, ambient temperature plays a major role in the life cycle of the malaria vector. Analysis of the spatial distribution and the temporal trends of rainfall is crucial for water resource management, agricultural productivity and climate change mitigation (Ayalew et al. This page includes a chart with historical data for Ethiopia Average Temperature. [6] Statistical relationships between the Ethiopia rainfall and other meteorological parameters or sea surface tempera-tures have been investigated in a number of papers [e.g., Degefu,1987;Segele and Lamb,2005;Korecha and Barn-ston,2007;Diro et al., 2011]. Gridded rainfall and temperature data were gathered from CenTrends Great Horn of … ao Daba MH (2018) Sensitivity of SWAT Simulated Runoff to Temperature and Rainfall in the Upper Awash Sab-Basin, Ethiopia. The rainfall varies from about 750 mm (29.5 in) a year in Tigray and Amhara to over 1,000 mm (39.4 in) in parts of Oromia. Rainfall and temperature are one of the most determinant climate patterns for the study area because more than 80% of the area’s agriculture is reliant on rain-fed. It takes about 9 to 10 days at temperatures of … 1). 17 . Nonlinear and synergistic effects of temperature and rainfall on the number of malaria outpatients were found in all seven sites. The development of the parasite within the mosquito (sporogonic cycle) is also dependent on temperature. About 15–29 percent of days will be considered hot by 2060.
