چکیده

This issue of Variations presents four articles highlighting modeling research presented at the CLIVAR-sponsored workshop on Coupled Ocean-Atmosphere-Land Processes in the Atlantic held in Miami, March 23-25, 2011. The workshop reviewed model biases in simulating the Atlantic (notably ocean circulation, sea surface temperatures, surface winds, clouds, and precipitation) and identified hypotheses on mechanisms responsible for the biases (see summary article on back page).

Coupled Climate Models on Grids

Community Climate System Model (CCSM) is a Multiple Program Multiple Data (MPMD) parallel global climate model comprising atmosphere, ocean, land, ice and coupler components. The simulations have a time-step of the order of tens of minutes and are typically performed for periods of the order of centuries. These climate simulations are highly computationally intensive and can take several days t...

Scaling climate simulation applications on the IBM Blue Gene/L system

We examine the ability of the IBM Blue Gene/Le (BG/L) architecture to provide ultrahigh-resolution climate simulation capability. Our investigations show that it is possible to scale climate models to more than 32,000 processors on a 20-rack BG/L system using a variety of commonly employed techniques. One novel contribution is our load-balancing strategy that is based on newly developed space-f...

Petascale atmospheric models for the Community Climate System Model: new developments and evaluation of scalable dynamical cores

We present results from the integration and evaluation of the spectral finite-element method into the atmospheric component of the Community Climate System Model (CCSM). This method overcomes the atmospheric scalability bottleneck by allowing the use of a true twodimensional domain decomposition for the first time in the CCSM. Scalability is demonstrated out to 86,200 processors with an average...

A flood risk projection for Soleimantangeh Dam against future climate change

A sensitivity analysis of the flood safety of Solaimantangeh dam using a regional climate change simulation is presented. Based on the output of the CCSM (Community Climate Change System Model) general circulation model, the NIRCM (North of Iran Regional Climate Model) computes regional scale output with 50 km spatial resolution and 21 vertical layers. Using the SRES (Special Report Emission Sc...

Overview of the Software Design of the CCSM

The Community Climate System Model (CCSM) is a computer model for simulating the Earth’s climate. The CCSM is built from four individual component models for the atmosphere, ocean, land surface and sea ice. The notion of a physical/dynamical component of the climate system translates directly to the software component structure. Software design of the CCSM is focused on the goals of modularity,...
