Climate Process Team: Improvement of Ocean Component of NOAA Climate Forecast System Relevant to Madden?Julian Oscillation Simulations

Pacific decadal oscillation hindcasts relevant to near-term climate prediction.

Decadal-scale climate variations over the Pacific Ocean and its surroundings are strongly related to the so-called Pacific decadal oscillation (PDO) which is coherent with wintertime climate over North America and Asian monsoon, and have important impacts on marine ecosystems and fisheries. In a near-term climate prediction covering the period up to 2030, we require knowledge of the future stat...

Impact of Ocean Model Resolution on CCSM Climate Simulations

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 hypothese...

Formulation of an ocean model for global climate simulations

This paper summarizes the formulation of the ocean component to the Geophysical Fluid Dynamics Laboratory’s (GFDL) climate model used for the 4th IPCC Assessment (AR4) of global climate change. In particular, it reviews the numerical schemes and physical parameterizations that make up an ocean climate model and how these schemes are pieced together for use in a state-of-the-art climate model. F...

An assessment of the surface climate in the NCEP climate forecast system reanalysis

This paper analyzes surface climate variability in the climate forecast system reanalysis (CFSR) recently completed at the National Centers for Environmental Prediction (NCEP). The CFSR represents a new generation of reanalysis effort with first guess from a coupled atmosphere–ocean–sea ice–land forecast system. This study focuses on the analysis of climate variability for a set of surface vari...
