People living on the east coast of Australia have been experiencing a rare meteorological event. Record-breaking rainfall in some regions, and very heavy and sustained rainfall in others, has led to significant flooding. In different places, this has […]

HEPEX has a reputation as a strong community of like-minded, supportive researchers and practitioners who are collectively bent on significantly advancing the science and applications of ensemble hydrological forecasting. HEPEX provides a unique forum where meeting people and […]

Research incubator projects At OzEWEX 2015 the idea was discussed to develop small collaborative projects on the practical topics between Bureau of Meteorology, CSIRO and university academics. As a result of that meeting, researchers from the University […]

New research shows that statistical methods developed for seasonal streamflow forecasting can also be used to predict streamflow over shorter times. Good streamflow forecasts allow water management agencies to make better decisions and achieve more efficient water use. Currently, the Australian […]

With parts of Australia once again in the grip of dry conditions, understanding climate variability and its impact on water supply is increasingly important. However, new research has found that models used by hydrologists to forecast long-term changes […]

Predictive models for streamflow have practical implications for better understanding drought hydrology, eco-hydrology and environmental monitoring, agriculture and water resource management. Recent work by Dr Ravinesh Deo and fellow researchers found that an extreme learning machine model can […]

Every day in the western US and elsewhere in the world, reservoir release decisions are made based in part on seasonal reservoir inflow forecasts created using a operational technique called Ensemble Streamflow Prediction (ESP, which originally stood for […]

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 […]

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 […]

The second OzEWEX national workshop was a great success, with well over a hundred participants, many inspiring presentations and lots of stimulating discussion. The workshop was held at in Broadbeach, Queensland, on 2 December 2015. We joined forces with the organisers of […]

New research has found that linear trends in rainfall across Australia between 1981 and 2014 were largely attributable to El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). The same study also found that both intra-annual and seasonal rainfall changes […]

Do you think it is better to pre-process the meteorological forecasts, to post-process the hydrological forecasts or to do both? Why? Following this blog about future directions for post-processing research, this challenge was mentioned in a comment by […]

El Niño has always been a key player in Australia’s climate. And as temperatures in the tropical Pacific Ocean show, the current El Niño event is the most significant since 1997. For many countries in the western equatorial […]

With an El Niño looming large this summer, it is very likely we will start to hear quite a bit about drought over the coming months. Inevitably, at some point you will hear someone say that the warmer […]

All in all, 55 participants attended last week’s HEPEX workshop on seasonal hydrological forecastingat SMHI. The aim of the workshop was to provide a forum for users, forecasters and researchers to discuss common issues and exchange ideas and […]

The 2015 El Niño is well and truly here. Heat is building in the equatorial Pacific Ocean; subsurface temperatures in the middle of the affected region are more than 6C above average, and the ocean’s surface is warming […]

The Bureau now forecasts likely streamflows for the next seven days at more than 100 locations across Australia. Our new 7-day streamflow forecasts service combines rainfall and streamflow observations with rainfall forecasts to indicate whether rivers are likely […]

Scientists are tipping this year’s forecast El Nino will be closely followed by a reverse La Nina weather system, swinging conditions from drought to flooding rains in some parts of Australia. There are predictions the coming El Nino, […]

I know there are many activities in the field of hydrology, including field hydrologist maintaining the gauging network and performing discharge measurements, scientist, model developers and forecasters. I will concentrate on the last group. So what makes you […]

The El Niño weather pattern developing in the Pacific Ocean could eventually rank among the strongest on record, forecasters with the US National Oceanic and Atmospheric Administration (NOAA) said on 13 August. NOAA Elevated ocean surface […]
