DCFP staff present their research at AMOS 2020

February 28th, 2020

Several DCFP staff presented their research at the Australian Meteorological and Oceanographic Society (AMOS) Annual Meeting and International Conference on Indian Ocean Meteorology and Oceanography in Fremantle, Western Australia in February 2020. The conference highlighted the current research in Indian Ocean oceanography and meteorology, with a strong water theme.

Amanda Black gave a presentation on her work titled ‘A dynamically-based investigation of Australian Northwest Cloudbands’. She demonstrated that a new, dynamically rigorous search algorithm was able to limit the amount of “false alarm” cloudband events detected to create an improved 40-year cloudband dataset. She also showed that Australian NW cloudbands are associated with significant rainfall supported by moisture transport via atmospheric rivers.

Carly Tozer delivered a Lightning Lecture on the ‘Large scale atmospheric processes associated with southeast Australian rainfall extremes and their representation in climate models’, as well as presentation on ‘An extreme rainfall event in Tasmania – process verification and attribution’.

Courtney Quinn presented in the General Oceanography session on collaborative work with colleagues from the University of Exeter and the Met Office Hadley Centre. The study analysed a box model of the global ocean as derived from the AOGCM FAMOUS. We performed different forcing scenario experiments related to additional freshwater flux into the North Atlantic Ocean and considered the effect on the behavior of the Atlantic Meridional Overturning Circulation. The results from the box model experiments were compared to results from similar experiments on the AOGCM HadGEM3-GC2, and the two studies showed comparable behaviour.

Doug Richardson presented his latest research “Identifying periods of forecast model confidence for improved sub-seasonal prediction of precipitation”. This work, co-authored with the Atmospheric Dynamics and Applications team, explored synoptic typing, using archetypal analysis, as a tool to assess forecast model confidence and the consequences for rainfall prediction in southern Australia.

Dylan Harries presented a poster at the meeting on work with CSIRO colleague Terry O’Kane and Illia Horenko (from USI Lugano) on using dynamic Bayesian networks for climate model assessment.

Ian Watterson gave a presentation on ‘Atmospheric moisture fluxes associated with heavy rainfall in the Indian and Australian monsoons simulated by CMIP6 models’, which was supported by his O&A research project on CMIP6 moisture fluxes.   There were many other relevant sessions too -with simulation and forecasting of Australian trends and droughts being a major theme.
