Atmospheric response to Atlantic tropical instability waves in Community Atmosphere Model version 3 [PDF]

Journal of Geophysical Research: Atmospheres, 2008
Tropical instability waves (TIWs) are 20‐ to 40‐day waves that appear along the sea surface temperature (SST) front of the equatorial cold tongues. In this study, we investigate the atmospheric planetary boundary layer response to TIW‐induced SST variations in the tropical Atlantic Ocean using Community Atmosphere Model version 3 (CAM3) developed at ...

Impacts of cloud superparameterization on projected daily rainfall intensity climate changes in multiple versions of the Community Earth System Model

Journal of Advances in Modeling Earth Systems, 2016
Changes in the character of rainfall are assessed using a holistic set of statistics based on rainfall frequency and amount distributions in climate change experiments with three conventional and superparameterized versions of the Community Atmosphere ...

Exploring Western North Pacific Tropical Cyclone Activity in the High‐Resolution Community Atmosphere Model

Earth and Space Science, 2022
High‐resolution climate models (∼28 km grid spacing) can permit realistic simulations of tropical cyclones (TCs), thus enabling their investigation in relation to the climate system.

Correcting For Telluric Absorption: Methods, Case Studies, And Release Of The TelFit Code [PDF]

, 2014
Ground-based astronomical spectra are contaminated by the Earth's atmosphere to varying degrees in all spectral regions. We present a Python code that can accurately fit a model to the telluric absorption spectrum present in astronomical data, with ...

Extending scalability of the community atmosphere model

Journal of Physics: Conference Series, 2007
The Community Atmosphere Model (CAM) is the atmosphere component of the Community Climate System Model (CCSM), and is the largest consumer of computing resources in typical CCSM simulations. The parallel implementation of the Community Atmosphere Model (CAM) employs a number of different domain decompositions. Currently, each decomposition must utilize

Difference in boreal winter predictability between two dynamical cores of Community Atmosphere Model 5

Environmental Research Letters, 2023
This study investigates the sensitivity of the boreal winter prediction skill of Community Atmosphere Model 5 to the choice of the dynamical core. Both finite volume (FV) and spectral element (SE) dynamical cores are tested.

Performance engineering in the community atmosphere model

Journal of Physics: Conference Series, 2006
The Community Atmosphere Model (CAM) is the atmospheric component of the Community Climate System Model (CCSM) and is the primary consumer of computer resources in typical CCSM simulations. Performance engineering has been an important aspect of CAM development throughout its existence. This paper briefly summarizes these efforts and their impacts over

Radiative effect and climate impacts of brown carbon with the Community Atmosphere Model (CAM5) [PDF]

Atmospheric Chemistry and Physics, 2018
A recent development in the representation of aerosols in climate models is the realization that some components of organic aerosol (OA), emitted from biomass and biofuel burning, can have a significant contribution to shortwave radiation absorption in ...

Pacific Ocean Forcing and Atmospheric Variability are the Dominant Causes of Spatially Widespread Droughts in the Contiguous United States [PDF]

, 2019
The contributions of oceanic and atmospheric variability to spatially widespread summer droughts in the contiguous United States (hereafter, pan-CONUS droughts) are investigated using 16-member ensembles of the Community Climate Model version 3 (CCM3 ...

Efficient Parallel I/O in Community Atmosphere Model (CAM) [PDF]

The International Journal of High Performance Computing Applications, 2008
Century-long global climate simulations at high resolutions generate large amounts of data in a parallel architecture. Currently, the community atmosphere model (CAM), the atmospheric component of the NCAR community climate system model (CCSM), uses sequential I/O which causes a serious bottleneck for these simulations.
