Mejora de la disponibilidad, el acceso y la utilización de la información climática
La variabilidad del clima y el cambio climático representan un importante desafío para el desarrollo sostenible en África. La actual crisis de hambruna en el Cuerno de África es solo otro recordatorio de cómo las fluctuaciones en el clima pueden destruir vidas y sustentos. Etiopía, uno de los países afectados por la actual sequía, ha sufrido las fluctuaciones del clima durante décadas. La variabilidad climática es uno de los principales obstáculos para el desarrollo en Etiopía. Las sequías y las crecidas han reducido el potencial anual de crecimiento del país en más de un tercio (Grey y otros, ...

Повышение уровня наличия, использования и доступа к климатической информации
Изменчивость и изменение климата являются серьезным испытанием для устойчивого развития Африки. Текущий кризис, вызванный голодом в странах Африканского Рога, является лишним напоминанием того, как колебания климата могут оказать разрушительное воздействие на жизнь людей и источники их существования. Эфиопия – одна из стран, подвергшихся воздействию засухи, – в течение десятилетий страдает от колебаний климата.

CGMS Baseline for the operational contribution to the GOS (adopted by CGMS-39 on 6 October 2011: Future satellite missions to be performed on operational/sustained basis
In support of the programmes coordinated or co-sponsored by WMO for weather and climate, CGMS Members plan to maintain the operational capabilities and services described below, that constitute the “CGMS baseline for the operational contribution to the GOS”. While this particular document focuses on missions that are decided and managed in an
operational or sustained framework, with a perspective of long-term follow-on, this in no way precludes the importance of other missions undertaken e.g. on a research or demonstration basis. First of all, because today’s research and development a ...

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. 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 ...

If the Price is Right- Development of a Methodology for Valuing Hydrologic Data : In 23rd Hydrology and Water Resources Symposium
Increasing restrictions on public funding for hydrologic data collection, and a trend over recent years for data collection activities to be driven by current specific use projects, have highlighted more than ever before the need to systematically assess the value of the benefits derived from the collection of hydrologic data. A most important aspect of this need is to make sensible, realistic estimates of the economic value of sll,ch benefits in dollar terms for current as well as for future uses of hydrologic data. Previous attempts to achieve this have been of limited practical application, ...
