discuss spatiotemporal distribution of temperature and rainfall in ethiopia
Therefore, the interannual rainfall distribution was very erratic. The magnitude of the significantly increasing trend of mean annual rainfall of 0.28 mm/year and 1.07% (DB station) was recorded, whereas a significantly decreasing trend of mean annual rainfall was observed with the values of 8.62 mm/year and 27.88% (HG station). The variation in the amount of solar radiation received daily is small throughout the year. Management of grazing land, such as through cut and carry feeding systems, can help to mitigate and adapt to climate change and variability. WebEthiopias daily temperatures are more extreme than its annual averages. Wondering how to get your business idea off on the right foot in the competitive..Learn More, Are you looking for a digital partner for your agency? This study analyses spatiotemporal variability and trends in rainfall and temperature in Alwero watershed, western Ethiopia. A significant increase in annual mean temperature was observed in all stations, with the magnitude varying from 0.03 C/year and 7.60% in DB station to 0.14 C/year and 31.30% at SD station. Copyrights 2022. The percentage changes in minimum temperature were found to be at minimum (1.90%) and maximum (52.40%) in GIN and DBS stations, respectively. Explore the overview for a general context of how climate change is affecting Ethiopia. The data is mostly observed station data supplemented by bias-corrected AgMERRA climate data. 2015; Pingale 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. 
Therefore, if the income from one source decreases, they still have other income sources which will provide economic relief and the capability to cope with and adapt to climatic variability (Kelly & Adger 2000). Therefore, clear information about the annual and seasonal rainfall distribution is highly important for policy planners and local users. For example, months from March to June in Ethiopiahave records of highest temperatures. Five years moving average temperature (19802014). On the other hand, 19 years (54.3%) recorded more than the annual average rainfall. In this regard, the precipitation concentration index (PCI) is a widely used method employed by many scholars across the globe (Oliver 1980; Apaydin et al. 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. If so, you are the right place. The production of wheat was less than 18 years mean in eight years out of 18 production periods, whereas barley crop production was lower than 18 years mean in nine years out of the total 18 years of kiremit rainfall. Here are the average temperatures. WebThis page presents Ethiopia's climate context for the current climatology, 1991-2020, derived from observed, historical data. In a study by Mekasha et al. 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. 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. 2014). Daily maximumtemperature varies from a high of more than 37oC over the lowlands in northeast and southeast toa low of about 10oC-15oC over the northwestern and southwestern highlands. 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. Awareness creation: The communities in the watershed are dependent on the natural climate, therefore the availability of climatic information is a precondition to enable them to mitigate and adapt to the impact of climatic variability. Whether developing new business models or managing enhanced cost pressure, We are redefining.. With the evolution of new opportunities in the field of Education, there are new mediums and.. Finance and banking institutions have started to rewrite their future with digital technologies, and this.. Real estate value can be easily driven by location but the digital disruptions into this indicate that the real.. The spatiotemporal rainfall and temperature distribution are presented in Figures4 and 5 respectively. 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. However, in the belg season during the period 19802014 the five years' average moving annual and seasonal rainfall was considerably variable. Therefore, there is a need for community-based coping and adaptation strategies such as adopting soil, water conservation and water harvesting strategies; and increasing diversified crops, high value and market oriented crops, fast growing crops and climate resistant crops, which are less susceptible to future climatic variability. Climatic variability in the past has been increasing and from the trends suggested in different studies, may further increase in the near future, putting urgent emphasis on how the community perceives the extent of climate change in order to design coping and adaptation strategies (Belay et al. However, during bega season the trend of all stations was downward. Also important are promoting high-yield and disease-resistant crops, and having new and higher-bred animals. The present results are in agreement with Parry (2007), who stated that due to a prolonged increase in the emission of gases through human activities and expansion of industry, the surface temperature has increased by about 1 C. Basic climatic parameters such as temperature, rainfall, relative humidity, wind, evapotranspiration, and aridity are considered and their spatial distribution is analyzed. 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.

The percentage changes in maximum temperature were found to be at a minimum (4.00%) and maximum (37.60%) in the GIN and ENW However, the magnitude of the significantly decreasing trend was observed at SD station (0.90 mm/year and 16.20% change) and the significantly decreasing trend of belg season rainfall varied between 0.12 mm/year and 10.00% at GIN station to a significantly increasing trend of 0.40 mm/year and 30.00% at DB station. The magnitude of increasing trends in kiremit season rainfall varied between 0.33 mm/year and a percentage change of 6.13% (DBS station) to 1.62 mm/year and 31.79% (DB). Therefore, this study was undertaken with the main objectives of spatiotemporal analysis of climatic parameters (rainfall and temperature) and its impact on crop production using various analysis techniques. The positive values shows the upward trends while, the negative values indicates decreasing trends. 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. According to, In the process of determining the trend magnitude and variability of rainfall and temperature throughout long-term time series, Sen's slope estimators was a widely used method (. Latitude,humidity and winds, with varying magnitude have also significant impacts on temperatureconditions in Ethiopia.
WebThis zone has warmer temperature and moderate rainfall. The region experiences most of its rain during summer (kiremt), while some placesalso receive spring (Belg) rain.
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. Therefore, in order to know the yields, annual rainfall is less important for prediction. The variation inthe amount of solar radiation received daily is small throughout the year. 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. Significantly, the increasing long-term annual minimum and maximum temperature during the study periods indicates that it is more likely this would contribute to the increase of mean annual temperature. 2011; Jain & Kumar 2012; Suryavanshi et al. Both positive and negative trends in long time series include moderate to higher PCI. The convergence of Northeast Trade winds and the Equatorial Westerlies forms theITCZ, which is a low-pressure zone.The inter-annual oscillation of the surface position of theITCZ causes a variation in the Wind flow patterns over Ethiopia and the Horn.
