BoM03: The role of soil moisture drought for wheat production in Australia

July 16, 2019 3:00 am Published by Comments Off on BoM03: The role of soil moisture drought for wheat production in Australia

The aim of this student project is to investigate the relationships between hydrological extremes (especially soil moisture drought) and wheat production in Australia. The outcome of the project may inform the development seasonal forecasts of hydrological indicators for agricultural production in Australia.

New dataset reveals key to Townsville flood disaster

CLEX researchers with the Bureau of Meteorology have created a new 20-year-long regularly updated precipitation dataset for Australia using 50 radar sites. This will allow researchers to examine the climatology of extreme events, follow cloud processes, estimate hail size, determine cloud top height and much more.

Research brief: Statistical correction reveals 25% decline in future rainfall over the SW Pacific

April 29, 2019 2:19 pm Published by Comments Off on Research brief: Statistical correction reveals 25% decline in future rainfall over the SW Pacific

CLEX researchers found that applying a statistical correction to projected sea surface temperatures has a major impact on changes to rainfall with global warming, leading to a 25% reduction in future precipitation projected for the south-western Pacific.

New students, an OA for Andy Pitman and some key work on evaporation, the impacts of mesophyll conductance on plant growth, a new algorithm for photosynthesis and future projections of drought made for a strong start to 2019.

Research brief: Changes to weather features of atmospheric conversion lines drive future changes to rainfall

Weather time scales will be needed for models to accurately simulate the dynamic contribution to future precipitation changes with global warming. This will better reproduce spatial patterns and reduce regional uncertainties, especially in the tropics.

Briefing note 003: Why are we uncertain about how extremely wet conditions will change in Australia in the future?

February 11, 2019 4:08 pm Published by Comments Off on Briefing note 003: Why are we uncertain about how extremely wet conditions will change in Australia in the future?

Computer models used to simulate global climate agree the climate will warm in response to increasing atmospheric greenhouse gases. However, a recent paper by Bador et al. (2018)1 includes results that highlight our uncertainty about exactly how extremely wet conditions will change in Australia. Further development of Australia’s national climate model, ACCESS, may help reduce this uncertainty.
