HEPEX Webinar: Statistical post-processing of ensemble weather forecasts: current development and future directions

HEPEX Webinar: Statistical post-processing of ensemble weather forecasts: current development and future directions

This webinar is co-hosted together with ECMWF and will be longer than usual, approximately 1 hour. Otherwise the procedure is as usual. Speaker: Tilmann Gneiting, University of Heidelberg Date and time: Wednesday, February 11, 2015 15:30 (UTC) Link to the recording here  Abstract: Statistical post-processing techniques serve to improve the quality of numerical weather forecasts, as they seek to generate calibrated and sharp predictive distributions of future weather quantities and events. I will review the state of the art in post-processing, with focus on ensemble forecasts and ongoing…

HEPEX Webinar: Discharge uncertainty: sources and implications for hydrological analyses

HEPEX Webinar: Discharge uncertainty: sources and implications for hydrological analyses

The Webinars are back for a new year of broadcasted science. A slight change in the format is that we will keep them shorter, around 20 min presentation with 10 min for discussion. First out 2015 is Ida Westerberg. University of Bristol. Date and time: Thursday, January 29, 2015 3:00 pm GMT  (UTC) A recording of the webinar is now available here Abstract: Uncertainty in discharge data affects the reliability of a range of hydrological analyses and is therefore important for the…

17th HEPEX Webinar: 2004-2014 – The rise of the meteorological ensembles in the HEPEX decade

The Webinars are back after a small break over the summer. First out for the season is one of the founding fathers of HEPEX, Roberto Buizza. Speaker: Roberto Buizza, ECMWF Date and time: Tuesday, September 30, 2014 3:00 pm GMT Summer Time  (UTC+01:00) Register: https://ecmwf.webex.com/ecmwf/onstage/g.php?t=a&d=954436834 Preview of the seminar:17th_HEPEX_Webinar_Buizza Abstract: In 2004, ECMWF hosted the first workshop that discussed the proposal for an International Hydrological Ensemble Prediction Experiment (HEPEX). This is how HEPEX started, with one of its main objectives being…

16th HEPEX Webinar: Using satellite snow cover images to enhance performance of snow, glacier and rain runoff projections for hydro power usages

16th HEPEX Webinar: Using satellite snow cover images to enhance performance of snow, glacier and rain runoff projections for hydro power usages

Speaker: David Finger Date and time: Thursday, May 29, 2014, 15:00 GMT Summer Time (UTC +01:00) Register: https://ecmwf.webex.com/ecmwf/onstage/g.php?t=a&d=958073775 Abstract: The quantification of snow, glacier and rainwater contribution to runoff in mountain streams is of major importance in order to anticipate adequate water management of hydropower reservoirs. While seasonal glacier melt contribution depends on general meteorological conditions during the summer months, snow cover is governed by winter precipitation and spring temperatures and direct runoff depends on rainfall patterns (e.g Crochet 2013)….

15th HEPEX Webinar: Flood Forecasting in Early Warning Systems

15th HEPEX Webinar: Flood Forecasting in Early Warning Systems

The next HEPEX webinar will be a bit different, since it is hosted not by us, but by CH2M HILL, who developed the ISIS software. The seminar is given by Murray Dale, and you can register for the seminar here. Date and time: Thursday 1 May at 10:00 BST (09:00 UTC) Abstract: Natural disasters are increasing in number and severity. Flooding, in particular, is a very damaging natural hazard. In the United States, where flood mitigation and prediction is advanced, floods…
