Rainfall and Temperature Climatology over Amhara Region

Studying spatial variations in rainfall and temperature is crucial for assessing climate-related changes and designing future water resource management strategies and agricultural planning. This study aims to analyze the climate parameters in the Amhara region of Ethiopia. Rainfall, maximum, and minimum temperatures data spanning from 1991 to 2020 were obtained from CHIRPSv2.0 and ERA5. The results showed that Amhara region had received mostly <i>Bega</i>, <i>Belg</i>, and <i>Kiremt</i> and annually 100-250 mm, 150-300mm, 800-1000 mm, and 1000-1300 mm rainfall, respectively. Climatologically Amhara region received a high amount of rainfall from June to September. Based on the annual rainfall cycle, <i>Bega</i> is the dry period over Amhara region. The results also showed that the mean maximum temperatures in <i>Bega</i>, <i>Belg</i>, <i>Kiremt</i>, and annually over Amhara region were 23-27°C, 27-30°C, 21-27°C, and 23-27°C, respectively. The study also revealed that minimum temperatures across Amhara ranged from 9-15°C for <i>Bega</i>, 12-18°C for <i>Belg</i>, 15-18°C for <i>Kiremt</i>, and 9-15°C annually. Based on these findings, we recommend that the Forecast and Early Warning, and Development Meteorology team use this recent climatology to give a seasonal climate forecast easily for various sectors to support the development of climate-resilient agricultural practices and water resource management strategies.
