CAWCR technical report, 61. Improvements in atmospheric physical parameterizations for the Australian Community Climate and Earth-System Simulator (ACCESS)
The Australian Community Climate and Earth-System Simulator (ACCESS) is a new coupled ocean and atmosphere climate modelling system being developed at the Centre for Australian Weather and Climate Research (CAWCR). ACCESS uses the UK Met Office Unified Model (Met UM, Davies et al. 2005) as its atmospheric component, which is coupled with the GFDL Ocean Model version 4.1 (MOM4p1, Griffies et al. 2009) and the Los Alamos National Laboratory Sea Ice Model version 4.1 (CICE4, Hunke and Lipscomb 2010), using the numerical coupler OASIS3.25 (Valcke 2006). The development of ACCESS has followed ...

The development of ACCESS has followed the implementation of the numerical weather prediction (NWP) system developed by the UK Met Office which uses the Met UM for atmospheric prediction with a 4-DVAR assimilation system [...].

CAWCR technical report, 42. Global climate goals for temperature, concentrations, emissions and cumulative emissions
Raupach Mickael R.; Harman Ian N.; Canadell Josep G. - Centre for Australian Weather and Climate Research, 2011There are many different ways of quantifying the broad goal of "avoidance of dangerous human interference with the climate system", including targets for global temperature rise, radiative forcing, greenhouse gas (GHG) concentrations, GHG emissions in particular years, and cumulative GHG emissions ("carbon budgets"). The purpose of this report is to provide relationships between these different statements of a climate goal. Broadly, the approach is to start from target for global temperature increase above preindustrial temperatures (such as two degrees Celsius or any other target, to be met w ...

There are many different ways of quantifying the broad goal of "avoidance of dangerous human interference with the climate system", including targets for global temperature rise, radiative forcing, greenhouse gas (GHG) concentrations, GHG emissions in particular years, and cumulative GHG emissions ("carbon budgets"). The purpose of this report is to provide relationships between these different statements of a climate goal. Broadly, the approach is to start from target for global temperature increase above preindustrial temperatures (such as two degrees Celsius or any other target, to be met with a given probability of success), then determine the radiative forcing and equivalent GHG concentrations consistent with the target, and finally the emissions consistent with the required concentrations. Results are summarised in tabular form (Tables S1, S2 and S3). These tables are also available in a spread sheet, allowing the effects of different temperature targets and probabilities of success to be investigated interactively.

Roll Vortices in the Boundary Layer Caused by a Concave Wind Profile: A Theoretical Study
Atmospheric and Oceanic Science Letters, Volume 3 Number 6. Liu Hui-Zhi; Sang Jian-Guo - Science Press, 2010The present study solves a two-layer atmospheric wave equation model with a lower atmosphere concave wind profile and cold-air outbreak over sea, while simultaneously proving that such a wind shear may cause neutral boundary layer roll vortices in the presence of disturbing sources upstream. Without thermal effects, the wind shear-induced waves have band structures at the top of the boundary layer that are similar to cloud street patterns observed over sea. This study proves that dynamic and thermal effects can act independently to initiate the roll vortices in the lower atmosphere. At the sam ...

in Atmospheric and Oceanic Science Letters > Volume 3 Number 6 (16 November 2010) . - p.308-311The present study solves a two-layer atmospheric wave equation model with a lower atmosphere concave wind profile and cold-air outbreak over sea, while simultaneously proving that such a wind shear may cause neutral boundary layer roll vortices in the presence of disturbing sources upstream. Without thermal effects, the wind shear-induced waves have band structures at the top of the boundary layer that are similar to cloud street patterns observed over sea. This study proves that dynamic and thermal effects can act independently to initiate the roll vortices in the lower atmosphere. At the same time, a quantitative comparison shows that dynamic effects play a large role in the formation of roll vortices in the initial stage of cold-air outbreak and will be surpassed by thermal effects soon after surface heating commences.

Calculation of new depth equations for expendable bathythermographs using a temperature-error-free method (application to Sippican/TSK T-7, T-6 and T-4 XBTs)
UNESCO, 1994 (Technical Series-No. 42)In recent times expendable oceanographic probes, in particular expendable bathythermographs (XBTS), have been a significant component of many large scale oceanographic research programmes, such as the Tropical Ocean Global Atmosphere (TOGA) Programme and the World Ocean Circulation Experiment (WOCE). These types of probes can be launched whilst underway from ships-of-opportunity, such as merchant vessels, enabling large scale repeated coverage of the major ocean basins. As the importance of the ocean’s role in the climate system has become increasingly acknowledged, so has the need to observe ...

Weather-based mathematical models for estimating development and ripening of crops
A treatment of the formulation and operation of various models which relate the rate of crop development to certain environ-mental factors (mainly temperature and photoperiod). Many applications are discussed, including crop zonation, land-use planning, management and operation of the production and processing of crops, characterizing genotype response to the environment and use as a biological time-scale submodel for monitoring crop conditions and forecasting yield.
