Comparing Detected Trends and Projections of Rainfall Precipitation of Global Climate Models (CCM4) over Sultanate of Oman

The available water resources are under risk due to escalating effects of climate change. Climate change estimates and projections need to be considered in order to improve environmental mitigation and monitoring. Variations in the quantity and intensity of precipitation have a major impact on how the environmental system responds to human influenced climate change, particularly in the Sultanate of Oman, which has a long history of common flash floods. In order to anticipate the precipitation levels for the years 2022–2050, this study uses the Community Climate System Model version 4 (CCSM4) to project future climatic changes in comparison to the historical recorded precipitation patterns in Sohar area in Oman for the years 2006–2022. The purpose of this study is to determine if climate change scenarios can be used to forecast the amount of precipitation. This study sheds light on future precipitation patterns with regard to the current impacts of climate change on local precipitation amounts. Additionally, the findings will support the country's decision-makers in their decisions for managing and mitigating the country's current water resources in order to reduce the effects of climate change.
