The Southwest Pacific Ocean circulation and climate Abstract The Southwest Pacific Ocean Circulation and Climate Experiment (SPICE) is an international research program under the auspices of CLIVAR. The key objectives are to understand the Southwest Pacific Ocean circulation and the South Pacific Convergence Zone (SPCZ) dynamics, as well as their influence on regional and basin-scale climate patterns. South Pacific thermocline waters are transported in the westward flowing...

Self-energy stochastic subgrid modelling in simulations of quasi-geostrophic and boundary layer flows Abstract Stochastic models are developed for the subgrid turbulence interactions in simulations of three-dimensional boundary layers, and quasi-geostrophic atmospheres and oceans. In geophysical (and engineering) simulations it is not possible to resolve all scales of motion, so one must resort to large eddy simulation (LES), where the large eddies are resolved on a...

Seasonality of biological and physical controls on surface ocean CO2 from hourly observations at the Southern Ocean Time Series site south of Australia Abstract The Subantarctic Zone (SAZ) is important for air-sea CO2 exchange, ventilation of the lower thermocline, and nutrient supply to global ocean productivity. Here we present the fi rst high-resolution autonomous observations of mixed layer CO2 partial pressure (pCO2) and hydrographic properties covering a full annual...

Improved air-sea flux algorithms in an ocean-atmosphere coupled model for simulation of global ocean SST and its tropical Pacific variability Abstract Enhanced algorithm for air-sea exchange parameterisation for momentum, sensible and latent heat flux parameterisation improves the climatic simulation of global sea surface temperature (SST) distribution and its Tropical Pacific variability. Based upon analyses and summary of field programs, we constructed new algorithms for...

Assessing the impact of observations on ocean forecasts and reanalyses: Part 2, Regional applications Abstract Ocean forecast and reanalysis systems routinely assimilate ocean observations to constrain ocean models to predict the three-dimensional ocean circulation. Under GODAE OceanView the operational ocean modelling community has developed a suite of global ocean forecast and analysis systems. Each system has a critical dependence on ocean observations – routinely...

Climate projections for southern Australian cool-season rainfall: insights from a downscaling comparison Abstract The projected drying of the extra-tropics under a warmer climate has large implications for natural systems and water security in southern Australia. Downscaling of global climate models offers the prospect of insights into the regional patterns of rainfall change in the mid-latitudes in the typically wetter cool season. The comparison of statistical and a...
