An invitation: help HEPEX program apps to teach the value of probabilistic forecasts

An invitation: help HEPEX program apps to teach the value of probabilistic forecasts

Contributed by Florian Pappenberger, Andy Wood, Maria-Helena Ramos, Schalk-Jan van Andel, Louise Crochemore, and Louise Arnal This is a blog for people who usually do not read this blog. This is a blog which asks for help so that our learning and teaching games and tools become more useful and widespread. This is a blog hoping that we can find some enthusiastic volunteers. The more people know how to use probabilistic forecasts, the better their decisions and the lower the…

Making connections through HEPEX – A CSIRO experience

Making connections through HEPEX – A CSIRO experience

By QJ Wang, Andrew Schepen, David Robertson, James Bennett, Durga Lal Shrestha, Yong Song and Tony Zhao members of the CSIRO Columnist Team 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 exchanging ideas has the very real potential to open up new, exciting collaborative research opportunities. Indeed, this has been the…

Using the Web for Environmental Big Data

Using the Web for Environmental Big Data

Contributed by Claudia Vitolo and Wouter Buytaert (Civil and Environmental Engineering, Imperial College London) About 90% of all the data in the world has been generated over the last two years1. At this rate, in 2015 we are expected to deal with 7.9 ZB (1 ZB = 1012 GB) of data, increasing to 35 ZB in the next five years2. A considerable share of these Big Data is the result of environmental related activities3,4 via computer simulation, as well as…

2015 Chinese New Year resolutions – HEPEX’s future in China

2015 Chinese New Year resolutions – HEPEX’s future in China

Contributed by Yi He, Qingyun Duan, Desmond Manful and Florian Pappenberger Let’s celebrate! Let’s get ready, because the goats are coming. According to the Chinese lunar calendar, the Year of the Wooden Goat starts on 19th of February 2015. Very much like the science of ensemble forecasting, the Chinese zodiac (Figure 1) is an ensemble of methods that can be utilized to predict people’s personality, fate and destiny. Let us, the atmospheric scientists, the HEPEX community, and people affected by…

Ensemble Hydrological Forecasting in China: Status and Prospects

Ensemble Hydrological Forecasting in China: Status and Prospects

Contributed by Qingyun Duan, Beijing Normal University, China The hydrometeorological services of the western countries, including the United States, Canada, Australia and many European countries, have already fully adopted ensemble forecasting methods operationally in their meteorological forecasts, and development and implementation of ensembles in their hydrological forecasts is well underway. Asian countries, particularly China, have been slow in taking on ensemble forecasting approach in their operational hydrological forecasts. As we enter the Year of the Sheep, I take this opportunity…
