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 […]
In an ideal world we would have river discharge measurements for every river spanning many decades and updated in real time. We all know this is very far from reality with severe gaps in the global observing network […]
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 […]
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 […]
The question sounds grand and may be a bit difficult to give a simple answer to, but that was the question put forward to the participants at the HEPEX workshop in Melbourne in February. HEPEX was founded as an initiative […]
In the afterglow of the highly successful 2016 HEPEX workshop in Quebec City, Canada, the planning for the next HEPEX workshop in 2018 in Melbourne, Australia is underway. Melbourne is far way for many HEPEXers, so we thought […]
A National Environmental Observation and Prediction System for the year 2030 The 4th national OzEWEX workshop explored what a future comprehensive National Environmental Prediction system should look like and what observations it will need. The workshop was held […]
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 ever-increasing volume of global environmental data and the continual increase in computational power continue to drive a push towards fully distributed modeling of the hydrologic cycle at hyper-resolutions (10-100 meters) [Wood et al., 2011]. In principle, this […]
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 […]

Good streamflow forecasts allow water management agencies to make better decisions and achieve more efficient water use. Currently, the Australian Bureau of Meteorology provides seasonal forecasts of three-month-total streamflow for over 200 gauging stations around Australia. Forecast users, particularly water management […]

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 […]

Information on precipitation is essential for almost any hydrological study. Unfortunately, precipitation is also one of the most difficult to estimate meteorological variables, due its tremendous spatio-temporal heterogeneity, particularly in tropical, mountainous, and snow-dominated regions. Over the past […]

After reading Chantal’s recent blog post discussing some of the limitations for international flood forecasting, and last week’s interview with Thomas Adams and Tom Pagano discussing their new book describing national and regional flood forecasting systems around the […]
As the 1st Edition of the book “Flood Forecasting, A Global Perspective” has just been released, Thomas Adams (UCAR) and Tom Pagano (BoM) [see their bio below], editors, recall how the idea of the book was born and […]

There have been a few posts on NWP performance lately, and so we thought we’d add our perspective. We’ve been working closely with the Bureau of Meteorology to extend their new 7-day deterministic streamflow forecasting service to an […]

There’s something about discussions of data handling that’s particularly soporific – but don’t nod off yet! Most hydrologists are trained to work on individual catchments and we often opt for simple conceptual models. In the pre-ensemble era, we […]
