Projection of Future Changes in Rainfall and Temperature Patterns in

摘要: Oman is one of most water-stressed countries in the world. Therefore, keeping water and energy supply demand equilibrium a pressing development challenge facing years ahead. The threat from potential impacts climate change has growing with recent tropical cyclones that had affected country caused loss life substantial damage throughout coastal areas Oman. design an effective strategy requires deep knowledge about past, present also accurate estimation plausible future climate. This paper presents rather complete picture current (1961-1990) (2011-2070) projection pattern rainfall temperature. For assessment over Oman, 21st century Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) A1B, forcing scenario used model National Center for Atmospheric Research (NCAR) Community System Model (CCSM-3). A1B clearly shows minimum temperature increases are line results shown temperatures will experience greatest impact change. simulation northern expected to face decreasing coming decades. In region where historic average annual levels between 50 100 mm coast area, lead 20 40 less by 2040. equivalent reduction 40%. With areas, groundwater recharge, surface flow quality decrease.
