PWS, 18. Guidelines on Communicating Forecast Uncertainty
World Meteorological Organization (WMO) ; Martin Claire; Cacic Ivan; et al. - WMO, 2008 (WMO/TD-No. 1422)Communicating the uncertainty of the forecast is vital to users. It allows them to make better decisions that are attuned to the reliability of the forecast. It also helps to manage the expectations of users for accurate forecasts. These Guidelines address the issue of communicating forecast uncertainty. Although they include a discussion on the sources of uncertainty, and touch on the related science (e.g. probabilistic forecasting, the use of Numerical Weather Prediction (NWP) ensembles), this is not their focus. Rather, the emphasis is on how National Meteorological and Hydrological Servic ...

PWS, 18. Directrices sobre la comunicación de la incertidumbre de las predicciones
Organización Meteorológica Mundial (OMM); Martin Claire; Cacic Ivan; et al. - OMM, 2008 (OMM/DT (ES)-No. 1422)Comunicar la incertidumbre de las predicciones es de vital importancia para los usuarios. Les permite tomar mejores decisiones acordes con la fiabilidad de las predicciones. Asimismo, ayuda a controlar las expectativas de los usuarios en lo que se refiere a predicciones precisas. En esta publicación se trata el tema de la comunicación de la incertidumbre de las predicciones. Si bien se incluye una descripción de las fuentes de incertidumbre y se mencionan las ciencias relacionadas (por ejemplo, la predicción probabilística y el uso de la predicción numérica del tiempo (PNT) por conjuntos), no ...
PWS, 18. Principes Directeurs Pour la Communication Relative à l'incertitude des prévisions
Organisation météorologique mondiale (OMM); Martin Claire; Cacic Ivan; et al. - OMM, 2008 (OMM/DT (FR)-No. 1422)Il est essentiel d’indiquer aux utilisateurs l’incertitude des prévisions. Cela leur permet de prendre de meilleures décisions fondées sur la fiabilité de ces prévisions, et cela permet aussi aux prévisionnistes de tenir compte de l’attente des utilisateurs en la matière. Les présents principes directeurs portent sur la communication relative à l’incertitude des prévisions. S’ils traitent des sources de cette incertitude et abordent des disciplines scientifiques connexes (prévisions probabilistes ou ensembles de prévision numérique, par exemple), tel n’est pas leur objet. Celui-ci est plutôt d ...
PWS, 17. Examples of Best Practice in Communicating Weather Information
World Meteorological Organization (WMO) ; Gill Jon; Cacic Ivan; et al. - WMO, 2007 (WMO/TD-No. 1409)This document presents some examples of how to effectively communicate weather information, across a range of services delivery methods and information types. Examples include graphical presentations on the internet and television, good use of icons and other weather symbols, and a case of effective verbal communication on radio. The examples are real. They have been chosen because they encompass one or more elements of effective communication, such as clear language, or simple but effective use of graphics. Users of this document are invited to examine the examples and use them as guidance ...

Il s’agit notamment de représentations graphiques sur Internet et à la télévision, du bon usage des icônes et d’autres symboles météorologiques, ainsi que d’un cas de présentation orale à la radio. Les exemples présentés sont réels. Ils ont été choisis parce qu’ils englobent un ou plusieurs éléments qui doivent entrer en ligne de compte dans la communication tels qu’une la ...
Guide to the WMO/GAW World Ultraviolet Radiation Data Centre, version 6.0
This document describes the procedures for data submission and information extraction at the World Ultraviolet Radiation Data Centre (WUDC), which is a subset of the World Ozone and Ultraviolet Radiation Data Centre (WOUDC). This document is intended as a guide for data originators and clients. The WOUDC web site is the primary medium for access to data, documentation and reports related to ozone and UV studies.

JCOMM Technical Report, 30. Verification of operational global and regional wave forecasting systems against measurements from moored buoys
World Meteorological Organization (WMO) ; Holt M.W.; Intergovernmental Oceanographic Commission (IOC) - WMO, 2006 (WMO/TD-No. 1333)Regional or basin-scale wave forecast model systems have been developed and run at various forecast modelling centres since the late 1970s, and as computer power grew during the 1980s, with the availability of global numerical weather prediction (NWP) models, global wave forecast models were established, often with nested regional wave models. Since that time, with increasing supercomputer capacity, the resolution of both global and regional wave models has increased, so that in 2004 a global wave model will typically have a grid spacing of ~50 km, close to or matching the resolution of the gl ...
DBCP Technical Document, 02. Reference Guide to the GTS Sub-system of the Argos Processing System - Revision 1.6
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2005The original Argos processing system was designed and implemented primarily to support the Global Weather Experiment in 1978/79. The processing requirement for the Global Telecommunication System (GTS) of WMO was intended to facilitate rapid global dissemination of data in standard format from the observation platforms (initially drifting buoys and constant level balloons) to the responsible research centres evaluating the observing systems. By the end of the 1980's, however, the diversity of users had expanded dramatically and it was apparent that the overall processing system was not well ma ...

Global spatial data and information : development, dissemination and use - report of a workshop
SEDAC, 2005Many different global- and regional-scale datasets on the environment and human development are being developed and disseminated by a range of institutions around the world. With the increasing use of more open, interactive mapping servers and greater capabilities by users to access and utilize large global datasets comes the potential for increased problems related to inconsistent data integration and visualization, variable data quality and documentation, uncoordinated proliferation of different versions of data sets, unnecessary duplication of effort, excessively complex restrictions on dat ...

JCOMM Technical Report, 24. Ice chart colour code standard
Intergovernmental Oceanographic Commission (IOC); World Meteorological Organization (WMO) - WMO, 2004 (WMO/TD-No. 1215)While the WMO international standard for ice charts only dealt with black and white charts, in keeping with the paper facsimile technology of the time, colour has long been used to help differentiate the various ice conditions on a paper chart. In the last decade, progress in computer processing and communication, as well as increased demands of users prompted the necessity to develop a new WMO International Ice Colour Code Standard for ice charts.
