High Resolution/Regional Climate Modeling

There is a great demand of more accurate and reliable model-based climate information at very high resolution (at regional to local scale) for a variety of applications. This includes higher resolution climate simulations and predictions, and reanalysis or other monitoring products. Significant advances beyond state-of-the-art climate modeling capability are needed to overcome current limitations. In view of recent progress in computer resources, global models that simulate climate at very high-resolution (e.g. 25km and under) are now being evaluated. It is important to prepare to fully exploit such a global high-resolution climate modeling capability.

The MAPP Program research efforts in this area include:

  • Research projects to support the development of next-generation global climate models involving both higher resolution and improved physical representations. The aim is to achieve a better understanding of how the simulation and prediction of climate variability in global models is affected by i) increases in model resolution and ii) the use of different cutting edge approaches in the representation of key physical processes (FY11-FY13).
  • The MRED research project to explore the impact regional downscaling (both dynamical and statistical) on seasonal prediction skill (funded FY08-FY10)
  • Research on high-resolution modeling by the Center for Ocean-Land-Atmosphere Studies jointly funded by NOAA, NSF and NASA (funded during FY09-FY13).

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
