Ultra-high-resolution climate simulation project

The ICCP has conducted ultra-high-resolution simulations with the goal of improving our understanding of scale-interactions and key mechanisms leading to climate variability and extreme weather events as well as exploring the sensitivity of the climate system to greenhouse warming.

The Community Earth System Model version 1.2.2 (CESM1.2.2) is employed to perform fully coupled (atmosphere, ocean, land, sea ice, river-runoff) global climate simulations. The atmospheric component is configured with about 25 km horizontal resolution and 30 vertical layers. The horizontal and vertical resolutions of the ocean component is about 0.1 degree and 62 levels, respectively.

Three experiments with different level of greenhouse gas condition were conducted:

The present-day run was started from a previous high-resolution simulation of Small et al. (2014) and we conducted a 140-year-long control simulation. The doubling and quadrupling CO2 forcing experiments were branched from year 71 of the present-day control run and were integrated for 100 years.
