Analysis of Precipitation and Temperature Trends Under the Impact of Climate Change Over Ten Districts of Jimma Zone, Ethiopia

Investigation of climate change impact on the optimal operation of koka reservoir, upper awash watershed, Ethiopia

“…The first four RCMs are forced by ICHEC-EC-EARTH, whereas the last RCM (CanRCM4) is forced by CCCma.CCCma-CanESM2. According to previous studies conducted in the different climatic zones of Ethiopia [ 19 , 25 , 36 , 37 ], the performance of the selected RCMs is adequate and acceptable.…”

Multi-purpose reservoir operation concomitant with estimating hydropower potential using multifarious hydrological models

“…Test for consistency of rainfall record by using Double mass curve : A graph ( Fig. 6 ) comparing the cumulative catch at the interest rain gauges versus the cumulative catches of one or more gauges in places that have seen comparable hydro-meteorological occurrences and are recognized to be consistent is called a double-mass curve (Equation (2) ) [ 29 , 30 ]. where : Px - Adjusted Rainfall of station, Px ’ - Observed Rainfall at station x, tan α′ - The slope of the adjusted mass curve, tan α – The slope of the Original mass curve.…”

On the Identification and Characterization of Outdoor Thermo-Hygrometric Stress Events

“…In addition to the official reports of national and international institutions (e.g., Intergovernmental Panel on Climate Change, US National Oceanic and Atmospheric Administration, European Environment Agency), also a plenty of recent scientific publications have been focused on observed and projected trends of temperature and precipitation (e.g., Viceto et al, 2019;Fanta et al, 2022;Lomakina and Lavrinenko, 2022), heat waves (HWs) (Fischer and Schär, 2010;Mbokodo et al, 2020;Perkins-Kirkpatrick and Lewis, 2020) and other extreme weather events (e.g., Tang, 2019;Almazroui, 2020). Great emphasis in still placed on different aspects of HWs, that can be broadly considered as "a period of consecutive days where conditions are excessively hotter than normal" (Perkins and Alexander, 2013a) or "from the human health point of view, a heat (cold) wave can be considered as a period with sustained temperature anomalies resulting in one of a number of health outcomes, including mortality, morbidity and emergency service callout" (Kovats and Kristie, 2006;Lavaysse et al, 2018).…”
