Tracing The Origins of ESP

Tracing The Origins of ESP

HEPEX Historical Hydrology Series, Edition 1 Contribution by Andy Wood, Tom Pagano, and Maury Roos, with special thanks to Mike Anderson 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 Extended Streamflow Prediction). ESP has become a key component of operational long lead prediction in a number of agencies (in the…

A timeline of developments at SMHI’s hydrological forecasting and warning service

A timeline of developments at SMHI’s hydrological forecasting and warning service

Contributed by Göran Lindström (SMHI) and Henrik Spångmyr (SMHI, Midvatten AB), members of the SMHI Guest Columnist Team The Swedish Meteorological and Hydrological Institute (SMHI) has a long tradition in developing customized products and services, as well as 24/7 production of forecasts with early warnings. In this blog, we summarize the development over time of SMHI’s hydrological forecasting and warning service. The first hydrological forecasts at SMHI date back all the way to 1913. Statistical methods for converting winter precipitation…

#FloodHack – Help improve the Global Flood Awareness System

#FloodHack – Help improve the Global Flood Awareness System

Are you interested in global flood forecasting? Are you a good code hacker? Or perhaps a bit of both? Then maybe a Hackathon would be something for you? On the 16-17 January ECMWF invites everybody interested in improving the Global Flood Awareness System (GloFAS) to a weekend of hacking. During the event we will improve the usability of the system as well as making use of new data sources and developing the system’s functionality. The event is free for everyone and we will…

From research to operations and vice versa: feedback from the HEPEX session at IUGG/IAHS workshop

From research to operations and vice versa: feedback from the HEPEX session at IUGG/IAHS workshop

Contributed by Maria-Helena Ramos, Fredrik Wetterhall and Andy Wood A Sunday in Prague can be spent in the tourist crowds on the main square, a leisurely stroll over the Charles bridge up to the castle to enjoy the stunning views, or it can be spent in at a conference centre attending “Hydrological Forecasting and Predictive Uncertainty: Advances and Challenges of Transferring Science into Operational Practice”. That was the title of the session at the IUGG General assembly/IAHS workshop that was…
