Collaboration the key to understanding the past, present and future of water availability in Victoria

The Victorian Water and Climate Initiative (VicWaCI) is a research collaboration between AWA members the Department of Environment, Land, Water and Planning (DELWP), Bureau of Meteorology, CSIRO and The University of Melbourne. In December of 2020, the anticipated […]

Can we achieve seasonally coherent forecasts given limited NWP data – across a continental domain?

Reliable weather forecasts are critical for the planning and management of a variety of social and economic activities, such as water management. To make such forecasts, numerical weather prediction (NWP) models have been developed. However, NWP models are […]

Why drought-busting rain depends on the tropical oceans

Recent helpful rains dampened fire grounds and gave many farmers a reason to cheer. But much of southeast Australia remains in severe drought. Australia is no stranger to drought, but the current one stands out when looking at […]

Regional reanalysis for precipitation data over Australia

Rainfall observations are important inputs for hydrometeorological applications. However, preparing a spatially and temporally consistent rainfall dataset is still a challenge because of sparse point measurements. One potentially valuable source of rainfall data with consistent spatial and temporal […]

Explaining historical decreases in flooding

Across large parts of Australia and the world flood magnitudes have decreased while rainfalls have increased. Our recently published research explains this apparent paradox: soils (or antecedent conditions) are becoming drier before it rains, meaning that, when it […]

Slowing climate change could reverse drying in the subtropics

As the planet warms, subtropical regions of the Southern Hemisphere, including parts of southern Australia and southern Africa, are drying. These trends include major drought events such as Cape Town’s “Day Zero” in 2018. Climate projections suggest this […]

Forecasting streamflow to 12 months – is it worthwhile?

In 2010, the Bureau offered an operational seasonal streamflow forecast service to the public – probably the first such service in the world to be made publicly accessible.  Users of the seasonal streamflow forecasts have provided positive feedback, […]
