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 ...
PWS, 17. Ejemplos de buenas prácticas para comunicar información meteorológica
Organización Meteorológica Mundial (OMM); Gill Jon; Cacic Ivan; et al. - OMM, 2007 (OMM/DT (ES)-No. 1409)En este documento se presentan algunos ejemplos de cómo transmitir de forma efectiva la información sobre el tiempo, a través de una serie de métodos de prestación de servicios y elementos informativos. Entre los ejemplos se incluyen presentaciones gráficas de Internet y de televisión, el uso adecuado de íconos y otros símbolos meteorológicos y un ejemplo de comunicación verbal efectiva en la radio. Los ejemplos son reales y han sido elegidos porque contienen uno o más elementos característicos de la comunicación efectiva, como un lenguaje claro o un uso sencillo, pero efectivo, de gráficos. ...
PWS, 17. Exemples de Bonnes Pratiques en Matières de Communications d'Informations Météorologiques
Organisation météorologique mondiale (OMM); Gill Jon; Cacic Ivan; et al. - OMM, 2007 (OMM/DT (FR)-No. 1409)Le présent document donne quelques exemples de la procédure à suivre pour communiquer avec efficacité des informations sur le temps, moyennant le recours à toute une gamme de méthodes de diffusion et de types d’informations. 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 ...
PWS, 10. Guidelines on biometeorology and air quality forecasts
These guidelines are intended to provide useful advice to National Meteorological and Hydrological Services (NMSs) on methods of incorporating air quality forecasts and biometeorological information into the suite of products and services offered to the public.The guidelines were developed by the Public Weather Services (PWS) Expert Team on Product Development and Service Assessment at the request of the Commission on Basic Systems (CBS). It is acknowledged that several NMSs already provide this type of information and some others are on the verge of developing an air quality programme. Howeve ...
Report of the 2001 global survey on the participation of women and men in the activities of the World Meteorological Organization
The second global survey on the Participation of Women and Men in the Activities of WMO was carried out in 2001, by means of a questionnaire. The objective was to update the data collected during a similar survey done in 1997, and track progress in achieving full opportunity for women in the meteorological and hydrological professions. This document provides an evaluation of the responses of 105 Members participating in the survey. The information presented will be a topic of discussion at the second WMO Conference on Women in Meteorology and Hydrology being organized in March 2003. The key co ...
PWS, 07. Supplementary guidelines on performance assessment of public weather services
The purpose of this Technical Document which is intended as a supplement to WMO/TD No. 1023, is to provide further elaboration of the concepts portrayed in WMO/TD No. 1023 and to re-enforce understanding through the provision of practical examples and models employed by various NMSs. Issues pertaining to some of the limitations of performance assessments are also discussed. Additionally, issues that require further investigation are highlighted. One broad area where further assessment focus is desirable is that of delivery of services as opposed to production of services
PWS, 06. Guide on the application of new technology and research to public weather services
In order to provide guidance to support NMSs, especially smaller Services and those in developing countries, in their service delivery activities by keeping pace with developments in technology, a Technical Document (PWS-1, WMO/TD No. 1054) was prepared in 1999 under the auspices of the WMO Technical Commission for Basic Systems (CBS) by the Public Weather Services Expert Team on Product Development and Verification and Service Evaluation. The purpose of that Technical Document was to provide a framework for the requirements of public weather services for data and products. At its twelfth sess ...
PWS, 05. Public weather services in Region VI (Europe): report of survey
World Meteorological Organization (WMO) ; Kusch Wolfgang; Kootval Haleh - WMO, 2002 (WMO/TD-No. 1100)This document provides an evaluation of responses to a questionnaire on public weather services (PWS) by WMO Members in Region VI (Europe). The questionnaire was developed by the RA VI Subgroup on Regional Aspects of Public Weather Services established by the Regional Association at its twelfth session (Tel Aviv, 1998).
PWS, 04. Guidelines on graphical presentation of public weather services products
A major downside to the rapid developments in communications technology, however, is in the area of graphics.On the one hand, developments in computer technology enable production of a vast array of graphic material, and on the other hand, lack of formal training to produce expertise in communication graphics has resulted in a scarcity of individuals with design capabilities. These guidelines attempt to bridge this gap. They are intended to provide information and assistance on how to develop graphics to suit the unique needs and circumstances of NMSs. They identify relevant graphic design pri ...
