Climate ProjectionsMean Projections

This page presents Oman’s projected climate. Information is shown by climatologies, as either projected mean or anomaly (change). We offer a range of variables at both national and sub-national aggregations. Data is presented spatially, as a seasonal cycle, time series, or heatplot, which shows seasonal change over long-term time horizons. Data can be analyzed as both annual and seasonal; monthly data is available in the Data Download page. You can further tailor your analysis by selecting different projected climatologies and emission scenarios, or Representative Concentration Pathways (RCPs). Projection data on this page is presented as multi-model ensembles, which represent the range and distribution of the most plausible projected outcomes of change in the climate system. It is important to note that RCPs are “what if scenarios” and provide insight into future climates based on defined emissions and mitigation efforts. Data for specific coordinates can be downloaded in the Data Download page.  

Climate projection data is modeled data from the global climate model compilations of the Coupled Model Inter-comparison Projects (CMIPs), overseen by the World Climate Research Program. The data currently presented is derived from the fifth phase of the CMIPs, CMIP5. The CMIPs form the data foundation of the IPCC Assessment Reports. CMIP5 is used for the IPCC's Fifth Assessment Report and CMIP6 will be used for the IPCC's Sixth Assessment Report. Projection data is presented at a 1.0º x 1.0º (100km x 100km) resolution.

Climate Data Projections

The climate science community sources a suite of models to inform decision makers on future climate. Among the most widely used are GCMs (Global Climate Models or Earth System models) that capture the non-linear complexity of the Earth to represent changes across the climate system for key processes and contexts.

Key Trends:

Temperature

  • Mean annual temperature is projected to increase by 1°C by 2050.

Precipitation

  • Mean annual precipitation is projected to increase by 2%.
  • The maximum amount of rainfall in any 5-day period (a surrogate for an extreme storm event) is projected to increase, while the maximum period between rainy days is expected to decrease.

The section below allows you to explore further climate indices derived from GCMs used in IPCC reports by different timeframes, statistics, emission scenarios, and models in map and charts.
