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 […]

My PhD research looks into how we can provide earlier indications of flood hazard at the global scale. One way of doing this is through seasonal forecasts of high (or low) river flow. Seasonal forecasts are designed to […]

Last week, 15,075 scientists from 106 countries attended the European Geosciences Union (EGU) General Assembly in Vienna. The week was jam-packed with more than 17,000 talks, posters and PICO presentations in 666 different sessions. The HEPEX community was […]

Due to various uncertainties in model inputs and outputs, initial and boundary conditions, model structures and parameters, raw forecasts from meteorological or hydrological models suffer from systematic bias and under/overdispersion errors and they need to be corrected before […]

How often do we assume that we understand the users’ needs, which may later be proven untrue? At the recent OzEWEX Australian Climate and Water Summer Institute – held in Canberra, Australia – we got the chance to bridge the […]

More than 120 HEPEXers from 15 countries descended on Melbourne, Australia, for three days of sunshine, science and applications at the 2018 HEPEX ‘Breaking the Barriers’ Workshop. The meeting kicked off with a warm welcome from the local organizing team […]

Precipitation is arguably the most important driver of the terrestrial hydrological cycle. Since most research and operational hydrological applications require precipitation data, most hydrologists have probably faced the following question: “Which precipitation dataset should I use among the […]

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, […]

TERN is making some changes to its land observatory. We are re-shaping our structure to place more importance on the way in which data derived from the local, regional and continental scale facilities is integrated and made more […]

ECMWF has launched a new seasonal prediction system (SEAS5) which brings better forecasts, especially for El Niño/La Niña events. Forecasts are also more detailed thanks to much greater horizontal resolution. An immediate application is the production of new GloFAS long-range […]

Rainfall predictions are extremely important to estimating flood risk. This month, news headlines have repeatedly reported floods and wild weather. June has seen the east coast of mainland Australia and Tasmania hit by storms causing significant flood damage. At the time of writing, flood warnings are […]

Of the water that makes it into our rivers, how much goes to the landscape, how much goes to the atmosphere, how much is extracted for consumptive use and how much flows out to sea? The Australian Water […]

The Bureau’s Water in Australia 2015–16 report shows that reserves in storages declined by seven per cent during the 2015–16 year. Despite annual rainfall being near average, it fell at the wrong time of year in many areas so reserves […]

Increased focus on dynamic modelling in our agricultural decision support tools, rather than the traditional statistical analysis will continue to improve Australia’s long-term forecasting systems. That’s the good news on the forecasting front, according to CSIRO senior climate […]

A colleague in my world-wide meteorological network made me aware of a CALMet conference in Melbourne, i.e. dealing with meteorological education and training. Through the website you can access the program with more or less extensive abstracts. I have no […]

The work of producing meteorological ensemble forecasts started 25 years ago at ECMWF and NCEP, and it sparked a revolution in both weather forecasts and its many applications. To celebrate this occasion, more than 100 people from across […]

The amount of water to be recovered under the Murray-Darling Basin Plan cold effectively be reduced by more than 600 gigalitres, following the recent Murray-Darling Basin Ministerial council meeting. Ministers have endorsed the final package of Sustainable Diversion […]

Science and forecasting practice are the foundations of the HEPEX community. These are certainly the routine of many of us during our office hours and while spending time in front of your computers. But this community is also […]

Back in September 2015 at the highly successful HEPEX Seasonal Hydrological Forecasting Workshop at SMHI in Norrkoping, Sweden, I heard a number of presentations and saw posters on the use of quantile mapping for post-processing or downscaling GCM […]
