Abstract We describe the baseline coupled model configuration and simulation characteristics of GFDL's Earth System Model Version 4.1 (ESM4.1), which builds on component developments at GFDL over 2013–2018 for carbon‐chemistry‐climate contributing to sixth phase Coupled Intercomparison Project. In contrast with CM4.0 development effort that focuses ocean resolution physical climate, ESM4.1 comprehensiveness system interactions. features doubled horizontal both atmosphere (2° 1°) (1° 0.5°)...
We describe the Geophysical Fluid Dynamics Laboratory's CM4.0 physical climate model, with emphasis on those aspects that may be of particular importance to users this model and its simulations. The is built AM4.0/LM4.0 atmosphere/land OM4.0 ocean model. Topics include rationale for key choices made in formulation, stability as well drift preindustrial control simulation, comparison historical simulations observations from recent decades. Notable achievements relatively small biases seasonal...
Abstract In Part 2 of this two‐part paper, documentation is provided key aspects a version the AM4.0/LM4.0 atmosphere/land model that will serve as base for new set climate and Earth system models (CM4 ESM4) under development at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL). The quality simulation in AMIP (Atmospheric Model Intercomparison Project) mode has been 1. provides components some sensitivities to choices formulation values parameters, highlighting convection parameterization...
Abstract In this two‐part paper, a description is provided of version the AM4.0/LM4.0 atmosphere/land model that will serve as base for new set climate and Earth system models (CM4 ESM4) under development at NOAA's Geophysical Fluid Dynamics Laboratory (GFDL). This version, with roughly 100 km horizontal resolution 33 levels in vertical, contains an aerosol generates fields from emissions “light” chemistry mechanism designed to support but prescribed ozone. Part 1, quality simulation AMIP...
Abstract The Convective Transport of Active Species in the Tropics (CONTRAST) experiment was conducted from Guam (13.5°N, 144.8°E) during January–February 2014. Using NSF/NCAR Gulfstream V research aircraft, investigated photochemical environment over tropical western Pacific (TWP) warm pool, a region massive deep convection and major pathway for air to enter stratosphere Northern Hemisphere (NH) winter. new observations provide wealth information quantifying influence on vertical...
Abstract Several studies have established that atmospheric flows a finite range of predictability, which may be reasonably considered consequence the underlying dynamics. In midlatitudes, error growth is predominantly associated with baroclinic disturbances. We consider midlatitude in two models: an idealized dry dynamical core and comprehensive general circulation model (GCM). By systematically varying equator to pole temperature gradients core, we show increasing Eady rates, time elapsed...
Abstract Global tropical cyclone (TC) frequency is investigated in a 50‐km‐resolution aquaplanet model forced by zonally symmetric sea surface temperature (SST). TC per unit area found to be proportional the Coriolis parameter at intertropical convergence zone (ITCZ), as defined latitude of maximum precipitation. As SST shifted northward from equator, precipitation moves and increases. When past 25°N, remains between 15°N 20°N, approximately constant. applied observed data, same scaling...
Abstract The Walker circulation connects the regions with deep atmospheric convection in western tropical Pacific to shallow‐convection, tropospheric subsidence, and stratocumulus cloud decks of eastern Pacific. purpose this study is better understand multi‐scale interactions between circulation, systems, interactive radiation. To do we simulate a mock‐Walker Circulation full‐physics general model using idealized boundary conditions. Our experiments use doubly‐periodic domain grid‐spacing 1,...
Abstract This study analyzes QuikSCAT surface wind data over the North Pacific Ocean to document distribution of captured fetches in extratropical cyclones that produced hurricane force (HF) fields from January 2003 through May 2008. A case is presented introduce datasets, which include analyses Global Forecast System (GFS) Data Assimilation (GDAS), and wave hindcasts third-generation model (WAVEWATCH III; hereafter, WW3), addition data. The analysis shows significant interannual variability...

Summary Containers have taken over large swaths of cloud computing as the most convenient way packaging and deploying applications. The features that containers offer for applications translate to high performance (HPC) well. At National Oceanic Atmospheric Administration, provide an easy build distribute complex HPC applications, allowing faster collaboration, portability, experiment computer environment reproducibility amongst scientific community. challenge arises when rely on message...
Abstract A new method for modeling the lowest model level vertical motion is described and validated. Instead of smoothing terrain heights, calculates gradient on a high-resolution grid averages values around gridpoint location. In essence, provides way to achieve some impact very steep flow without computational overhead associated with high resolution needed fully resolve complex terrain. The more accurate depiction leads an increase in orographic causes rainfall occur often over...
Abstract We performed a series of aquaplanet simulations at the horizontal resolution from 50 to 6 km with identical parameterization settings using Geophysical Fluid Dynamics Laboratory's Atmosphere Model version 4 implemented two‐moment Morrison‐Gettelman cloud microphysics prognostic precipitation (GFDL AM4‐MG2). At finer resolution, global mean resolved‐scale increases and that cumulus decreases. The model also simulates less/thinner clouds over low latitudes more/thicker high as...
