    A three-dimensional primitive-equation hydrodynamic model was applied to the Huon Estuary and D'Entrecasteaux Channel in south-eastern Tasmania to characterise the physical oceanography of the coupled system. Model results verify that the Huon Estuary behaves as a salt-wedge estuary, and can be considered the driver for residual circulation for the system; the bottom . Daily outputs from the CSIRO Conformal Cubic Atmospheric Model, driven by four general circulation models, were used in a stochastic weather generator, LARS-WG, to construct local climate scenarios for key cotton production areas in eastern Australia.

    1. Introduction The new MPI Earth System Model (MPIESM) consists of the atmospheric general circulation model(GCM)ECHAM6,thelandvegetationmodelJSBACH,theoceanGCMMPIOM andtheocean. Atmospheric general circulation models are developed for simulation of current climate of the earth and are able to predict the earth's future climate change. In this paper, the performance of GFDL CM, CSIRO Mk3 and HadCM3 AOGCMs were assessed and evaluated in the study of the climate change effects on temperature and precipitation in.

    Simulations of future climate are carried out by down-scaling the Commonwealth Scientific and Industrial Research Organization (CSIRO) Mark General Circulation Model (Gordon et al, ) for 10 years () under the SRES A2 scenario using the Cubic Conformal Atmospheric Model (CCAM) (McGregor and Dix, ). Atmospheric General Circulation Model Jet stream and fractional cloud cover The atmospheric general circulation model (AGCM) originated from the NCAR Community Climate Model version 1 (CCM1, described in Williamson , ), although most modules have been extensively modified or replaced since work began in

He led the CSIRO Ocean Downscaling Strategic Project to provide high-resolution (1/10 °) future climate change signals in the ocean simulated by CMIP5 climate models with a near-global eddy-resolving ocean general circulation model.

Before joining CSIRO, he studied and worked at University of Washington, NOAA/Pacific Marine Environmental. Global climate change, such as that due to the proposed enhanced greenhouseeffect, is likely tohave a significant effect on biosphere-atmosphere interactions, includingbushfire regimes.

Thisstudy quantifies the possible impact of climate change on fire regimes byestimating changes infire weather and the McArthur Forest Fire Danger Index (FDI), an index thatis used.

Under winter wind stress conditions the model had a tendency to buildup ice on the Siberian coast. The introduction of a partial slip condition at land‐ice boundaries in the model designed to prevent this buildup is discussed, and the best choice for the amplitude of the slip at the land boundaries in this model is found to be We analyze energy and water transport in present, doubled CO 2, and tripled CO 2 climates simulated by the Mark 2 CSIRO nine‐level general circulation model with a mixed layer ocean.

This is an “equilibrium” model simulation in which both 1 × CO 2 and 2 × CO 2 runs are performed for fixed concentrations of CO 2 ( and ppm, respectively). Climate change is a significant change in weather or in its variability in a long period.
