Forecast Verification Research

wwrp logo
  • To plan and implement the verification component of WWRP;
  • To serve as a focal point for the development and dissemination of new verification methods for WWRP and EPAC, as required;
  • To facilitate and encourage training and dissemination of information on verification methodologies;
  • To take into account the needs of users so as to ensure the relevance of the practice of forecast verification;
  • To facilitate the development and application of improved diagnostic verification methods to assess and enable improvement of the quality of weather forecasts, including forecasts from numerical weather and climate models;
  • To encourage the sharing of observational data for verification purposes;
  • To encourage greater awareness in the research community of the importance of verification as a vital part of numerical and field experiments rather than an "afterthought";
  • To promote collaboration among scientists conducting research on various aspects of forecast verification as well as with model developers and forecast providers; and
  • To collaborate on forecast verification with the Working Group on Numerical Experimentation (WGNE) and WCRP and in coordination with CBS.

News

 

  • Forecast Verification Research Working Group Meeting
    (Montreal, Canada, 23 August 2014)

  • WWRP is pleased to announce that the Sixth International Verification Methods Workshop will be held in New Delhi, India from 13-19 March 2014. The goal of the workshop is to promote recent advances in the theory and practice of verification of weather and climate forecasts worldwide. The workshop welcomes participants from operational, research, and forecast user communities to discuss methods for more effectively measuring and conveying the accuracy and utility of forecasts and warnings. The workshop includes both a tutorial session (March 13-15) and a scientific program (March 16-19). The scientific program will feature keynote addresses as well as contributed talks and posters on new verification techniques and issues related to the practice of forecast verification. Please find attached the first announcement and call for papers.

The deadline for application to the tutorial is November 30, 2013.
The deadline for submission of abstracts is January 15, 2014.

NEW  First Announcement and Call for Papers   NEW 6IVMW poster

  • Forecast Verification Method Intercomparison Project (ICP): Several members of the Joint Working Group on Forecast Verification Research have participated in the ICP, which is an effort to provide useful information on new verification approaches that have been developed in the last few years.  The initial focus has been on spatial verification aproaches including object based methods, scale separation approaches, neighborhood methods and field morphing approaches.  The methods were all applied to the same datasets, including some artificial cases that allow easy interpretation, as well as some high resolution model forecasts from the central US.  The results of these studies are now available for early release as a  special collection in the journal Weather and Forecasting.  At a recent informal workshop for this project plans were developed to extend the project to new datasets and variables.  This project is a significant step toward development of a verification method testbed, which would be supported by this Joint Working Group.
