Temperature, rainfall and humidity have been associated with the dynamics of malaria vector populations and, therefore, with spread of the disease. 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. Mean annual temperatures are around 15‐20˚C in these high altitude regions, whilst 25‐30˚C in the lowlands. Figure 3: Areas where lack of rain or erratic rain is considered to be a key factor . 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. 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. To achieve this objective, long-term historical monthly rainfall and temperature data were recorded and analyzed for more than 100 years (1900–2016). 11. 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 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. in contributing to vulnerability . It has observed an upward livelihood patterns but fluctuating over the study period. 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. Find the best time to go to Addis Ababa. In Ethiopia, higher elevations receive more rainfall than low arid areas and support agricultural livelihoods and higher population densities (fig. This study investigates the temporal variability and trend of temperature and rainfall in Gelana sub-watershed, northern highlands of Ethiopia. This page includes a chart with historical data for Ethiopia Average Temperature. 2015). Vol. 2019; Gebrechorkos et al. The frequency of hot days and nights will substantially increase. About 15–29 percent of days will be considered hot by 2060. International Journal of Environmental Monitoring and Analysis. 1). J Earth Sci Clim . Particular attention is paid to the way the different signals superimpose and evolve within the course of the season. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. 6: 320. doi: 10.4172/2157-7617.1000320.

North eastern Ethiopia is one of the sensitive regions to climate variation particularly to temperature and rainfall changes. 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. 17 . The impact of climate change has received a great deal of attention worldwide. Gridded rainfall and temperature data were gathered from CenTrends Great Horn of … Results show that significant coupled modes of variability exist, with the first dominant coupled mode … 4, 2020, pp. 1). 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. 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. 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. Ethiopian areas, affected by a continuous forest and woodland decline. 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. Even in the hottest months (March to May), average highs rarely exceed 77 degrees Fahrenheit (25 degrees Celsius). Inter-annual variability of precipitation and rising trends of temperature has observed [3]. OMICS Internat ional: Publication Benefits & Features. 8, No. However, rainfall is highly variable across the country, from season to 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. 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. 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. It takes about 9 to 10 days at temperatures of … 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. 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. 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). (ENSO) and Vegetation Dynamics in Gojjam, Ethiopia. Nonlinear and synergistic effects of temperature and rainfall on the number of malaria outpatients were found in all seven sites. Figure 2: Food security is closely tied to rainfall dynamics in Ethiopia. Higher temperature, exceeding 30 °C, is recorded in the northern and eastern parts of Ethiopia, western Kenya, and Tanzania. Weather in January » Especially, ambient temperature plays a major role in the life cycle of the malaria vector. Ethiopia is a large complex country, with complex patterns of rainfall and livelihoods (Livelihoods Integration Unit, 2010). In Ethiopia, mean annual temperature has increased by 1.3°C between 1960 and 2006, an average rate of 0.28°C per decade. Average precipitation (rainfall, snow) in millimeter per month in Addis Ababa, Ethiopia displayed in a beautiful overview. 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. Temperature in Ethiopia decreased to 21.97 celsius in December from 22.68 celsius in November of 2015. The development of the parasite within the mosquito (sporogonic cycle) is also dependent on temperature.   Throughout the year, temperatures drop quickly once the sun goes down, and frosty mornings are common. The fine grid spacing (<6 km) is adequate to depict mesoscale topography (Goswami et al., 2012), which resolve areas of high and low elevation. 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. dynamics that initiate seasonal rains. ao Daba MH (2018) Sensitivity of SWAT Simulated Runoff to Temperature and Rainfall in the Upper Awash Sab-Basin, Ethiopia. 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. Africa is one of the most vulnerable continents due to its high exposure and low adaptive capacity (Niang et al. [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]. Weather in January » The Amboseli basin, a semi‐arid, open savannah area of southern Kenya, has experienced extensive changes in habitat since the early 1960's. Seasonal rainfall in Ethiopia is driven mainly by the migration of the Inter‐Tropical Convergence Zone (ITCZ). 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. 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. 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).
