Sydney is hot. Well technically, it’s persistently warm and lacking cool outbreaks, but this run of weather is no less remarkable for that. The city has had a record 31 straight days above 26℃ (and counting), smashing the […]

Floodplain lakes of the Yarra River became increasingly disconnected from the main river over the course of the 19th and 20th centuries. This discovery was highlighted in a new study published in Science of The Total Environment by […]

Recent work by Acacia Pepler and fellow researchers found that the frequency of East Coast Lows will likely decrease in the latter part of the 21st century. East Coast Lows (ECLs) are a critical weather event for the […]

A recent study by Dr Eun-Pa Lim and colleagues demonstrated a connection between long-term trends in sea surface temperatures and amplified wet conditions in subtropical Australia during La Niña. Variations of Australian seasonal climate depend heavily upon the […]

Recent work by Dr Adrian Fisher and his colleagues describes the comparison of seven different water index methods for automated water classification in eastern Australia, using near coincident high-resolution imagery as reference. A new Landsat water index developed […]

You may have picked up on some news about climate science job cuts at CSIRO. Perhaps you got confused by all the commentary, or did not have time to follow it all. To help you, here a summary of some of the things that […]

In the climate research community it is well accepted that global climate models do a relatively poor job at capturing daily precipitation characteristics, due to the small spatial scales involved. What is far less known is that observations […]

As Perth sweats through a severe heatwave, pressure is mounting on the city’s dwindling water supplies. Dried tree stumps litter the baked earth at the edge of the Canning Dam, 33 kilometres out of Perth. It was not […]

For the Northern Jarrah Forest (NJF) region of southwest Western Australia, Landsat satellite imagery supports more accurate forest sensitivity analysis than airborne monitoring survey by plane. Recent work by Dr Niels Brouwers, and his fellow researchers indicates that […]

The world’s climate is already changing. Extreme weather events (floods, droughts, and heatwaves) are increasing as global temperatures rise. While we are starting to learn how these changes will affect people and individual species, we don’t yet know […]

The CSIRO’s climate science divisions are expected to be pared back as part of a massive shake-up of the organisation. The ABC understands cuts are expected to be made within the Oceans and Atmosphere and Land and Water divisions […]

Australia’s rainfall is perhaps the most variable of any continent on Earth. When averaged across the country, rainfall in 2015 was only slightly below normal. However, there were large areas of both extreme dry and relative wet across […]

It’s official: 2015 was the hottest year on record. The US-based National Oceanic and Atmospheric Administration has confirmed overnight that 2015 saw the global average temperature climbing to 0.90°C above the 20th-century average of 13.9°C. The record has […]

A stocktake of waterbirds in eastern Australia has shown the lowest breeding level on record. The annual aerial survey, conducted by the Centre for Ecosystem Science at the University of NSW, confirmed a dramatic long-term decline in the […]

To start of 2016 on a positive note, HEPEX is happy to invite contributions to a special issue in HESS on sub-seasonal to seasonal hydrological forecasting. The special issue is a follow-up on the workshop in Norrköping in September […]

Drought has affected most regions of the globe in the early 21st-century. In Australia, the recent Millennium Drought from 2001 until 2009 was the worst on record and ended dramatically with one of the largest La Niña […]

Today the Australian Bureau of Meteorology has released its yearly climate update. A strong El Niño event was the headline story underlying global climate in 2015, but its impact in Australia was mixed. In some parts of the […]

Surface irrigation water demand in the northern Murray-Darling Basin can be better accounted when using remotely-sensed irrigation extent and rates of actual evapotranspiration in hydrologic modelling, both in terms of magnitude and temporal patterns. In their recent study […]

New research suggest that integrating satellite soil moisture observations into a simple land-surface model can improve the modelled root-zone soil moisture significantly. Evaporation determines the availability of surface water resources and the requirements for irrigation. In addition, through its impacts on […]

The coastal catchments of southeast Australia may be affected less by large-scale climatic drivers than previously assumed, according to recent research by Rafael Carvalho and colleagues from the University of Wollongong. The study looked at the spatial variation in rainfall for Shoalhaven […]
