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…

14th HEPEX Webinar: Projection of occurrence of extreme dry-wet years and seasons in Europe with stationary and nonstationary Standardized Precipitation Indices

14th HEPEX Webinar: Projection of occurrence of extreme dry-wet years and seasons in Europe with stationary and nonstationary Standardized Precipitation Indices

Speaker: Simone Russo Date and time: Wednesday, March 26, 2014, 15:00 UTC Register: https://ecmwf.webex.com/ecmwf/onstage/g.php?t=a&d=957913545 Abstract: The probabilities of the occurrence of extreme dry/wet years and seasons in Europe are estimated by using both the Standardized Precipitation Index (SPI) and the Standardized non-stationary Precipitation Index (SnsPI). The latter is defined as the SPI by fitting precipitation data with a non-stationary Gamma distribution, in order to model the precipitation time dependence under climate change. Daily precipitation outputs from five different regional climate…

13th HEPEX Webinar: An overview of NOAA’s second-generation global ensemble reforecast data set

13th HEPEX Webinar: An overview of NOAA’s second-generation global ensemble reforecast data set

Speaker: Tom Hamill Date and time: Thursday, February 27, 2014, 15:30 UTC Register: https://ecmwf.webex.com/ecmwf/onstage/g.php?t=a&d=952488674 Abstract: NOAA scientists recently completed the generation of a ~30 year, daily medium-range global ensemble reforecast data set that uses roughly the same NCEP Global Ensemble Forecast System that was made operational in 2012. We maintain a hard-disk archive of 99 different output fields at the NOAA Earth System Research Lab in Boulder, which are readily accessible via web interface or ftp. An archive of the…

12th HEPEX webinar: Operational flood forecasting and early warning at European and Global scale

12th HEPEX webinar: Operational flood forecasting and early warning at European and Global scale

Speaker: Lorenzo Alfieri Date and time: Thursday, January 30, 2014, 15:00 UTC Register: https://ecmwf.webex.com/ecmwf/onstage/g.php?t=a&d=956437634 Abstract: Flood forecasting and early warning systems operating at continental scales have a key role in providing large-scale overview of hydrological conditions and upcoming extreme events. They are meant to be nearly unsupervised, fully automated and based on relatively simplified approaches, able to spot extremes at an early stage and trigger subsequent in-depth analysis at regional scale. This talk will first present the current status of…
