Nonlinear precipitation response to El Nino and global warming in the Indo-Pacific Abstract Precipitation changes over the Indo-Pacific during El Niño events are studied using an Atmospheric General Circulation Model forced with sea-surface temperature (SST) anomalies and changes in atmospheric CO2 concentrations. Linear increases in the amplitude of the El Niño SST anomaly pattern trigger nonlinear changes in precipitation amounts, resulting in shifts in the location and...

Evaluation of clouds and convection in a limited-area numerical weather prediction system using near real-time CloudSat-CALIPSO observations Abstract Near real-time measurements from the CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) mission are used to evaluate the representation of the hydrometeor frequency of occurrence (HFO) in the limited-area version of the Australian Community Climate and Earth-System Simulator (ACCESS-A),...

Greenhouse Gas Network Design for Australia Abstract Monitoring major greenhouse gases (GHGs) such as carbon dioxide (CO2) and methane (CH4) is important, not only for the continuous observation of atmospheric concentrations in order to detect global trends, but also for deriving GHG fluxes and their uncertainties on a regional scale. The flux uncertainties are dependent on the network of atmospheric GHG measurements. Here, we aim to assess how the current network of GHG...

Dynamical seasonal ocean forecasts to aid salmon farm management in a climate hotspot Abstract Marine aquaculture businesses are subject to a range of environmental conditions that can impact on day to day operations, health of the farmed species, and overall production. An understanding of future environmental conditions can assist marine resource users plan their activities, minimise risks due to adverse conditions, and maximise opportunities. Short-term farm management...

Adaptive management of marine mega-fauna in a changing climate. Abstract Management of marine mega-fauna in a changing climate is constrained by a series of uncertainties, often related to climate change projections, ecological responses, and the effectiveness of strategies in reducing alleviating the impacts from climate change. Uncertainties may be reduced over time through adaptive management. Adaptive management is a framework for resource conservation that promotes...

Australian carbon tetrachloride emissions in a global context Abstract Global (1978-2012) and Australian (1996-2011) carbon tetrachloride (CCl4) emissions are estimated from atmospheric observations of CCl4 using data from the Advanced Global Atmospheric Gases Experiment (AGAGE) global network, in particular from Cape Grim, Tasmania. Global and Australian emissions are in decline in response to Montreal Protocol restrictions on CCl4 production and consumption in the...
