In line with the study by Wu et al. Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. In the rainfall distribution during belg and kiremit it was found that there was a moderate concentration of precipitation throughout the seasons, which shows that there is no uniform distribution, whereas during the bega season a significant change in the PCI was shown, thus the concentration of precipitation is increasing and rainfall has become more erratic. 2010; Simane et al. Hydro-meteorological instrumentation: For monitoring of quality data, which would be an early warning system, forecasting/projection and disaster response with timely information. After visual identification of the outliers, each of the values was obtained using a normal ratio technique. During this season, Northeasterly windsoriginating from the landmass of Asia dominantly prevail Ethiopian landmass. Throughout the year, 1,160 mm (46 in) of rain fall, with a maximum from June to September, which is Even though the rainfall indicates seasonal and inter-annual variability, the area is characterized by a bimodal rainfall regime, with maximum rainfall concentration during kiremit (summer) season, which extends from June to September.

Backed with rising consumer demands.. 2014). Based on PCI results, rainfall during the summer and spring seasons is moderately distributed as compared to annual and winter season rainfall. Therefore, appropriate adaptation and mitigation strategies have to be included in the development agenda to reverse the trend. Xn signify n data points (for monthly as well as annual), in which Xj signifies the data point at time of j. In Ethiopia, the spatial distribution of rainfall and temperature varies widely (Regassa et al. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. This study analyses spatiotemporal variability and trends in rainfall and temperature in Alwero watershed, western Ethiopia. According to Griggs & Noguer (2002), Babel et al. The available data for crop production (Q/ha) over 18 years (19972014) for the major crops such as barley, wheat, beans, peas, lentils and chickpeas were obtained from the district office of Agriculture and Central Statistical Authority. The average rainfall inthe region varies from 1,400 to over 2,200 mm/year.iii.
The problem is high in developing countries, particularly sub-Saharan countries in which the majority of the population live on rainfed agriculture. The region is divided in to dry and wet summer rainfall regions.Hence, the wet corresponds to the area having rainfall of 1,000 mm or more.

discuss spatiotemporal distribution of temperature and rainfall in ethiopia happy to be a part of the team synonym 2023 "Moroni's America" - The North A significantly declining trend of bega season rainfall was observed in all stations with the trend magnitude of 0.61 mm/year and 7.50% in GIN station to 0.21 mm/year and 56.40% in DBS station. At the annual scale, maximum and minimum temperatures significantly increased in over 33% of the Basin at a rate of 0.1 and 0.15 C per decade, respectively; however, the western part (12%) of. The region experiences most of its rain during summer (kiremt), while some placesalso receive spring (Belg) rain. Precipitation projections indicate increased mean precipitation with more frequent extreme rainfall during monsoon season in the EH region, and a wetter cold season in the WH region. Spatiotemporal Distribution of TemperatureAltitude is an important element in determining temperature of Ethiopia and the Horn. Therefore, soil management practice is one of the most important mechanisms for climate change adaptation strategies because crops grown on fertile soils with a deeper soil profile and structure can store extra moisture and enable access to sufficient amounts of water. Generally, the climate is controlled by the Intertropical Convergence Zone (ITCZ) and has a clear bimodal rainfall pattern: the rainy season is from June to September, and the dry season is from October to April. Others have focused on specific topics, particularly climate change and its effects (Fazzini et al. 1.1. Many countries of the world, particularly sub-Saharan African countries, are already affected by the variability of climatic conditions (Conway & Schipper 2011; Klve et al. Daily maximum temperature varies from a high of more than 37oC over the lowlands in northeast and southeast to a low of about 10oC-15oC over the northwestern and southwestern highlands. The percentage change over a period of time can be obtained from Sen's median slope and mean by assuming the linear trend in the long-term series using the following formula: In statistical terms, the moving average is also known as running average, used in order to explore a set of various data by creating an average value of various subsets for a data set. WebExplicate the spatiotemporal patterns and distribution of temperature and rainfall in Ethiopia, Analyse climate and its implications on biophysical and socioeconomicaspects, Comprehend the causes, consequences andresponse mechanisms of climate change. Water Resources Potentials and Development in Ethiopia, CHAPTER FIVE THE CLIMATE OF ETHIOPIA AND THE HORN, 5.2. Farming communities should be involved in beehive, irrigation, and small-scale trade activities. Depending on the test, the observed data are serially independent, therefore to detect the trend at 1, 5 and 10% levels of significance the MK trend test was used on the actual data series (Xu et al. The High altitudesand the windward side experience such rainfall amount.ii. For instance, unlikeother parts of Ethiopia, the southern and southwestern highlands experience reducedtemperature. Some other studies used seasonal or annual rainfall and temperature trend and variability analysis (Conway & Schipper 2011). Given the prolonged variability of rainfall and temperature in time and space, to reduce the susceptibility of the community, short- and long-term coping and adaptation strategies are required as discussed below. Make Daspal your technology partner to bring innovative ideas into reality. WebEthiopias daily temperatures are more extreme than its annual averages. Basic climatic parameters such as temperature, rainfall, relative humidity, wind, evapotranspiration, and aridity are considered and their spatial distribution is analyzed. The northeasterly winds crossing the Red Seacarry very little moisture and supplies rain only to the Afar lowlands and the Red Sea coastalareas.iv. This is probably due to the fluctuation and variability of the seasonal and inter-annual rainfall pattern of the Beressa watershed during the last few decades, as indicated in Table3, which is similar to other studies (Muhire & Ahmed 2015; Zhao et al. The study watershed lies between 39 37E39 32E and 9 40N9 41N. discuss spatiotemporal distribution of temperature and rainfall in ethiopia. From Figure3, it is confirmed that the maximum temperature has continuously increased by about 1.10 C, whereas the minimum temperature has increased by about 0.70 C. All the given crops show considerably high correlation with belg rainfall. Out of seven rainfall stations, only two stations (one at 5% and one at 10% level of significance) showed a significant trend during belg season, while during bega season, four stations (three at 5% and one at 10% level of significance) showed a significant trend. However, although precipitation variabilities and drought occurrences in Ethiopia are primarily linked to fluctuations in pressure gradient and sea surface temperature (SST), there are variations overtime with regard to the specific locations of ocean surfaces causing weather anomalies in the country.
Such studies ignored the localized trends of rainfall and temperature, particularly in most highlands of Ethiopia. Out of seven stations, long-term annual maximum temperature has shown a significantly increasing trend (three stations at 5% significance level and two stations at 10% significance level). The correlation between rainfall during the months of MaySeptember and crops has a positive relationship, except in the cases of beans, peas and chickpeas, which are inversely correlated with rainfall during the month of June. Investigating the influence of sea surface temperatures (SSTs) on seasonal rainfall is a crucial factor for managing Ethiopian water resources. Investigating the influence of sea surface temperatures (SSTs) on seasonal rainfall is a crucial factor for managing Ethiopian water resources. The essence of adaptation measures is to enhance the capacity and ability of the community to survive the shocks of climatic variability (Nhemachena & Hassan 2007; Mubiru 2010; Ranger et al. 2016). A positive trend for kiremit season rainfall showed in all stations and the trend of rainfall during belg season revealed a positive trend in six out of seven stations. Soil management: Soil erosion and degradation reduces crop productivity for traditional farming practices (particularly for mountainous area like the Beressa watershed), as erosion and degradation occurs at a higher rate than fertile soil formation. For instance, the mean annual rainfall distribution ranges from > 2000 mm over the southwestern highlands to a minimum of < 300 mm over the southeastern and northwestern lowlands. This process is repeated for the whole data sequence. Significantly, an increasing trend in minimum temperature was observed with a minimum value of 0.005 C/year in GIN station to a maximum value of 0.12 C/year in DBS station. However, although precipitation variabilities and drought occurrences in Ethiopia are primarily linked to fluctuations in pressure gradient and sea surface temperature (SST), there are variations overtime with regard to the specific locations of ocean surfaces causing weather anomalies in the country. The average annual aerial rainfall of the Beressa watershed is 891 mm, with a coefficient variation of 30.6% and standard deviation of 227 mm. Spring (March, April and May)In this season, the noonday sun is shining directly on the equator while shifting north from south.The shift of the ITCZ, results in longer days and more direct solar radiation providing warmerweather for the northern world. WebThis page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. For this purpose, SST and rainfall data were used to study a wide range of inhomogeneous areas in Ethiopia with uneven distribution of rainfall for both summer (1951–2015) and spring 2013; Pachauri et al. The variation in the amount of solar radiation received daily is small throughout the year. Both increasing and decreasing trends of climatic variables were observed. Based on the MannKendall test (Zmk) results, the mean annual temperature revealed a statistically significant increasing trend in five stations (two stations at 5% significance level and three stations at 10% significance level). The results from the coefficient of variations shown in Table2 revealed that in comparison with the kiremit rainfall season, during the bega and belg seasons rainfall varies considerably more. It is the second largest zone covering more than 26% of the landmass of Ethiopia. The time series of five years moving average minimum and maximum temperature was analysed for the period 19802014. Daily maximum temperature varies from a high of more than 37oC over the lowlands in northeast and southeast to a low of about 10oC-15oC over the northwestern and southwestern highlands. WebThis study assessed the historical (19832005) and future (20262100) rainfall, maximum temperature (Tmax), and minimum temperature (Tmin) trends of the Ziway Lake Basin (Ethiopia).

Therefore, given the prolonged climatic variability of the Beressa watershed, the following coping and adaptation mechanisms are suggested.
This study analyses spatiotemporal variability and trends in rainfall and temperature in Alwero watershed, western Ethiopia.
Sponsored Schools. All crop production shows considerably high correlation with maximum temperature and stronger correlation with barley, while in the case of minimum temperature, poor correlation was observed for all crops. The temperature and rainfall of this category is highly suitable for majority of crops grown in Ethiopia. The Impacts of Relief on Biophysical and Socioeconomic Conditions, CHAPTER FOUR DRAINAGE SYSTEMS AND WATER RESOURCE OF ETHIOPIA AND THE HORN, 4.3. On the other hand, 19 years (54.3%) recorded more than the annual average rainfall. Assessing the long-term spatiotemporal rainfall distribution pattern is the most significant component in the climate analysis of a given country, more specifically at the local and regional levels where the effect of climate change is worse. The rainfall and temperature daily records over 35 years (19802014) for the Beressa watershed were obtained from the National Meteorological Service Agency of Ethiopia from seven stations; hence rainfall on a monthly, seasonal and annual basis were derived from the daily data. 2015).
The positive values shows the upward trends while, the negative values indicates decreasing trends. 2012; Meshesha et al. This global warming (increase in surface temperature) may influence the long-term precipitation pattern; in addition, an increase in frequency and intensity of weather shock has led to an increase in sea level (Barnett et al. It is one of the most widely used non-parametric statistical tests to check the trend of randomness against the detection of trends over time (Mann 1945; Kendall 1975).
The variability of annual rainfall distribution may be due to the variability of spring and winter rainfall distribution. discuss spatiotemporal distribution of temperature and rainfall in ethiopia happy to be a part of the team synonym 2023 "Moroni's America" - The North The moving average is possibly acquired by considering the initial subset average. Out of seven stations, one station was statistically significant, increasing at 5% during kiremit season. Conversely, low temperatures are recorded fromNovember to February.It is not easy to observe distinct variation in temperature between seasons as the sun is alwayshigh in the tropics. WebThis zone has warmer temperature and moderate rainfall. The Geological Time Scale and Age Dating Techniques, 2.4. 2016). WebThe period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. Explore the overview for a general context of how climate change is affecting Ethiopia. This development mainly happens in July in Ethiopia and the Horn causingvariability and seasonality.The ITCZ shifts towards south of equator (Tropic of Capricorn) in January. With respect to the statistically significant level, only barley and wheat crops are significantly related to belg and kiremit rainfall. Thus, the rainfall system in Ethiopia is characterized by spatial and temporalvariabilities.Rainfall in Ethiopia is the result is influenced by the position of Intertropical Convergence Zone(ITCZ). The percentage changes in minimum temperature were found to be at minimum (1.90%) and maximum (52.40%) in GIN and DBS stations, respectively. It lies between 1500-2,300 meters above sea level. 2015). The annual rainfall distribution is also variable in time and space. 2017a, 2017b). The results of correlation analysis between crop production and climatic variables (rainfall and temperature) during the period 19972014 are shown in Table5. 2009). As the shift takesplace, equatorial westerlies from the south and southwest invade most parts of Ethiopia bringingmoist winds.However, these winds decrease the length of rainy seasons and magnitudes on the line of theshift. Seasonal or Temporal VariabilitiesWhat winds bring summer rainfall for Ethiopian highlands?The rainfall is highly variable both in amount and distribution across regions and seasons.The seasonal and annual rainfall variations are results of the macro-scale pressure systemsand monsoon flows which are related to the changes in the pressure systems discussed in theprevious sections of this chapter. When the tropical depression is observed in the SWIO, the daily rainfall is significantly decreased.
As already explained. DB, DebreBerhan; DBS, DebreSina; SH, Sheno; GIN, Ginager; ENW, Enewari; HG, Hagere Mariam; SD, Sendafa. 2010). Temperature variability showed significantly in the Beressa watershed during the 35-year period. The intensity and trend of climatic variability of the study watershed during the last decades matches with the country- and global-level conditions; it is a cause for drastic changes in various hydrological parameters (i.e. Other studies have focused on very limited stations and arrived at a conclusion regarding the characteristics of spatial climatic variability for entire regions (Gamachu 1988; Meze-Hausken 2004). 2012). 5.1 Water Resources: Rivers, Lakes and Sub-Surface Water, 4.4.
The trend of increasing maximum temperature is stronger than the minimum temperature. Conversely, the southeasterlies from the Indian Ocean provide rain to the highlands ofSomalia, and to the central and southeastern lowlands and highlands of Ethiopia. The details of these seven stations are presented in Table2. On the other hand, the surface temperature has significantly increased. 
The calculated PCI for seasonal as well as inter-annual rainfall distribution for the spatiotemporal time series is shown in Table2. Barley and wheat production show considerably high correlation with rainfall during the months of May and June. The rainfall and temperature daily records over 35 years (19802014) for the Beressa watershed were obtained from the National Meteorological Service Agency of Ethiopia from seven stations; hence rainfall on a monthly, seasonal and annual basis were derived from the daily data. ochsner obgyn residents // discuss spatiotemporal distribution of temperature and rainfall in ethiopia WebEthiopias daily temperatures are more extreme than its annual averages. In the last few decades, incidence of climate change related hazards have manifested in the form of recurrent drought, erosive rain, rainfall variability and flood events (Kenabatho et al. The rainfall and temperature daily records over 35 years (19802014) for the Beressa watershed were obtained from the National Meteorological Service Agency of Ethiopia from seven stations; hence rainfall on a monthly, seasonal and annual basis were derived from the daily data. Investigating the influence of sea surface temperatures (SSTs) on seasonal rainfall is a crucial factor for managing Ethiopian water resources. The temperature and rainfall of this category is highly suitable for majority of crops grown in Ethiopia. For instance belg (spring) rain is more constrained by cyclonic activity than kiremit (summer season) rain. However, after 1999 and onwards, recovery in the long-term average rainfall emerged higher than the average mean, except for the drier conditions in 2002 and 2013 which were lower than the long-term mean. Thus temperature, as it is affected by altitude, decreasestowards the interior highlands. However, local farmers evaluate climatic variability in relation to their crop productivity. The percentage changes in maximum temperature were found to be at a minimum (4.00%) and maximum (37.60%) in the GIN and ENW stations respectively. Mean annual minimum and maximum temperatures increased from 12.69 to 13.32 C and 26.43 to 26.91 C from 1981 to 2010, respectively. 2005). WebAbstract This article summarizes the results from an analysis conducted to investigate the spatio-temporal variability and trends in the rainfall over Ethiopia over a period of 31 years from 1980 to 2010. Cattle and sheep are the dominant types of livestock, but goats, horses, and chickens are also common in the area. In this season, the effect of the northeast trade wind is very muchreduced.
