The Australian Community Climate and Earth System Simulator coupled model (ACCESS-CM) has been developed at the Centre for Weather Research (CAWCR), a partnership between CSIRO 1 Bureau of Meteorology.It is built by coupling UK Met Office atmospheric unified (UM), other sub-models as required, to ACCESS ocean model, which consists NOAA/GFDL 2 MOM4p1 LANL 3 sea-ice CICE4.1,under CERFACS 4 OASIS3.2-5coupling framework.The primary goal ACCESS-CM development provide climate community with new...
A new version of the Australian Community Climate and Earth System Simulator coupled model, ACCESS-CM2, has been developed for a wide range climate modelling research applications. In particular, ACCESS-CM2 is one Australia’s contributions to World Research Programme’s Coupled Model Intercomparison Project Phase 6 (CMIP6). Compared with ACCESS1.3 model used our CMIP5 submission, all components have upgraded as well coupling framework (OASIS3-MCT) experiment control system (Rose/Cylc). The...
Abstract The most recent Intergovernmental Panel on Climate Change assessment report concludes that the Atlantic Meridional Overturning Circulation (AMOC) could weaken substantially but is very unlikely to collapse in 21st century. However, largely neglected Greenland Ice Sheet (GrIS) mass loss, lacked a comprehensive uncertainty analysis, and was limited Here community effort, improved estimates of GrIS loss are included multicentennial projections using eight state‐of‐the‐science climate...
Climate models predict an upward trend of the Southern Annular Mode (SAM) in response to increasing atmospheric CO 2 concentration, however consequential impact this change on oceanic circulation has not been explored. Here we analyse outputs a series global warming experiments from CSIRO Mark 3 climate model. We show that although for zonal wind stress maximum is located at approximately 60°S, terms surface curl, situated 48°S. This curl causes spin‐up entire southern midlatitude ocean...
The summer moisture transport by the large-scale circulation over China has been investigated using ECMWF–WMO twice-daily analyses for period 1980–96. horizontal flux of atmospheric water vapor and its divergence calculated two target regions, namely, southeast (25°–35°N, 110°–120°E) northeast (40°–50°N, 120°–130°E). time-averaged fluxes show southeastern Asian Indian monsoon circulations bringing abundant from South Sea Bay Bengal, respectively, to while midlatitude westerlies dominate...
Abstract. Earth system models (ESMs) that incorporate carbon–climate feedbacks represent the present state of art in climate modelling. Here, we describe Australian Community Climate and System Simulator (ACCESS)-ESM1, which comprises atmosphere (UM7.3), land (CABLE), ocean (MOM4p1), sea-ice (CICE4.1) components with OASIS-MCT coupling, to carbon modules have been added. The model (as part CABLE) can optionally include both nitrogen phosphorous limitation on uptake. (WOMBAT, added MOM)...
There are two versions of global coupled climate models developed at the Centre for Australian Weather and Climate Research (CAWCR) participating in phase 5 Coupled Model Inter-comparison Project (CMIP5), namely ACCESS1.0 AC-CESS1.3.This paper describes CMIP5 experimental configuration AC-CESS forcings historical future scenario runs.We also present an initial analysis model results, concentrating on changes surface air temperature hydrologic cycle, sensitivity.Both somewhat underestimate...
During year-to-year El Niño events in recent decades, major sea surface warming has occurred frequently the central Pacific. This is distinct from eastern Pacific pattern during canonical events. Accordingly, central-Pacific exerts impacts on ecosystems, climate and hurricanes worldwide. The increased frequency of new type presents a challenge not only for understanding dynamics its change but also prediction global at present future climate. Previous studies have proposed different indices...
The Australian Community Climate and Earth System Simulator (ACCESS) has contributed to the World Research Programme’s Coupled Model Intercomparison Project Phase 6 (CMIP6) using two fully coupled model versions (ACCESS-CM2 ACCESS-ESM1.5) ocean–sea-ice (1° 0.25° resolution of ACCESS-OM2). models differ primarily in configuration version their atmosphere components (including aerosol scheme), with smaller differences sea-ice land versions. Additionally, ACCESS-ESM1.5 includes biogeochemistry...
Episodic explosive volcanic eruptions are a natural part of the climate system but often omitted from atmosphere‐ocean general circulation model (AOGCM) preindustrial spin‐up and control experiments. This omission imposes negative bias on ocean heat uptake in simulations historical period. In models range complexity, we find that global‐mean sea level rise due to thermal expansion during last ∼ 150 years is consequently underestimated by 5–30 mm, which substantial proportion mean 50 mm...
Cloud properties from the Australian Community Climate and Earth System Simulator (ACCESS1.3) are evaluated using Feedback Model Intercomparison Project (CFMIP) Observational Package (COSP). CloudSat, CALIPSO, International Satellite Climatology (ISCCP) observations used to evaluate modeled cloud cover, condensate properties, optical depths for two seasons. The global distribution of in model is generally well represented with maximum high tropics low over eastern edges ocean basins....
Examinations of the impact anthropogenic aerosols on oceanic heat content have focused largely global average response. Given that aerosol‐induced cooling is greater in Northern Hemisphere (NH) than Southern (SH), do induce a NH content? Sea level rise over past 50 years has shown little hemispheric differentiation. Using set climate model experiments forced with and without aerosols, we show increasing 20th century pan‐oceanic redistribution. This leads to reduction SH comparable oceans....
Global and regional diagnostics are used to evaluate the ocean performance of Australian Community Climate Earth System Simulator coupled model (ACCESS-CM) contributions Model Intercomparison Project phase 5 (CMIP5). Two versions ACCESS-CM have been submitted CMIP; namely CSIRO-BOM ACCESS1.0 ACCESS1.3. Results from six core CMIP5 experiments (piControl, historical, rcp45, rcp85, 1pctCO2, abrupt4xCO2) evaluated for each two versions. Overall, both exhibit a reasonable stable representation...
Abstract El Niño–Southern Oscillation (ENSO) is the dominant mode of interannual climate fluctuations with wide-ranging socioeconomic and environmental impacts. Understanding eastern Pacific (EP) central (CP) Niño response to a warmer paramount, yet role internal variability in modulating their not clear. Using large ensembles, we find that generates spread standard deviation skewness these two types similar 17 models from phase 5 Coupled Model Intercomparison Project (CMIP5) realistically...
We analyse and document the historical simulations performed by two versions of Australian Community Climate Earth System Simulator (ACCESS-CM2 ACCESS-ESM1.5) for Coupled Model Intercomparison Project Phase 6 (CMIP6). Three ensemble members from each model are used to compare simulated seasonal-mean climate, climate variability change with observations over period. Where appropriate, we also ACCESS results 36 other CMIP6 models. find that winter summer mean climates (over global domain)...
Abstract. A new configuration of the Australian Community Climate and Earth System Simulator coupled model, ACCESSCM2, with a higher resolution ocean-sea ice component at 0.25° is introduced. The ACCESS-CM2-025 model was developed to better represent ocean mesoscale expand scope climate modelling research applications. individual components have not been changed compared ACCESS-CM2-1, existing lower version 1°, which one Australia’s contributions World Research Program’s Coupled Model...
Abstract Internal tides are generated in the stratified ocean interior by interaction of barotropic tidal currents with rough bathymetry. Low‐vertical‐mode internal can transport energy far from their generation site, but it remains unclear how and where this is eventually dissipated at small scales. A potential mechanism for transfer low‐mode to smaller scales equatorial regions superharmonic generation, whereby nonlinear self‐interaction non‐uniform stratification excites waves shorter...
This study uses a regime sorting technique to explore the relationships that ACCESS1.3 clouds have with large‐scale environment. Satellite simulator output is used demonstrate modeled similar sensitivity dynamic and thermodynamic conditions as shown by CloudSat Cloud‐Aerosol Lidar Infrared Pathfinder Observation (CALIPSO). The high cloud cover longwave radiative effect represented very well in model across all regimes. types simulates most poorly are stratocumulus over cool sea surface...
