CCSM CAM3 Climate Simulation Sensitivity to Changes in Horizontal Resolution
نویسندگان
چکیده
The latest version of the Community Climate System Model (CCSM) Community Atmosphere Model, Version 3 (CAM3), has been released to allow for numerical integration at a variety of horizontal resolutions. One goal of the CAM3 design was to provide comparable large-scale simulation fidelity over a range of horizontal resolutions through modifications to adjustable coefficients in the parameterized treatment of clouds and precipitation. Coefficients are modified to provide similar cloud radiative forcing characteristics for each resolution. Simulations with the CAM3 show robust systematic improvements in a variety of features, most notably associated with the large-scale dynamical circulation. We will focus on simulation differences between the two principal configurations of the CAM3, which differ by a factor of two in their horizontal

[1] Simulations of mixed-phase clouds in forecasts with the NCAR Atmosphere Model version 3 (CAM3) and the GFDL Atmospheric Model version 2 (AM2) for the MixedPhase Arctic Cloud Experiment (M-PACE) are performed using analysis data from numerical weather prediction centers. CAM3 significantly underestimates the observed boundary layer mixed-phase cloud fraction and cannot realistically simulate...
