A Disaster Risk Reduction Roadmap for the World Meteorological Organization : final draft (version 2.1), 31 March 2017
The Roadmap is first and foremost a document that can be used by both WMO Members, partners and users to understand how NMHSs in partnership with other agencies contribute to increasing the resilience of communities, nations, regions, and the world under the above-mentioned frameworks, through a coordinated WMO-wide plan of action on DRR. It is hoped that this Roadmap will guide the Organization, in particular the NMHSs as well as key partners, in the development of its strategic and operating plans that fully take into account the contributions of the WMO community to all components and phase ...
Guide to the Management and Operation of WMO Regional Training Centres and Other Training Institutions
This publication responds to the recommendations made in the review of the future roles and operation of RTCs, which was carried out by the Executive Council Panel of Experts on Education and Training from 2012 to 2014. The review and recommendations were approved by the WMO Executive Council at its sixty-sixth session in 2014. The review underlined the importance and usefulness of the RTCs to WMO Members. However, it also noted that, for Members to get even more value from such centres, the criteria for designation and reconfirmation of RTCs needed to be improved and that Directors of RTCs wo ...
Guidelines for the Assessment of Uncertainty for Hydrometric Measurement
In view of the increasing pressure on water resources, National Hydrological Services (NHSs) worldwide are faced with the challenge to deliver hydrological services of high quality, timeliness and proven credibility, to assist the decision making process of water and natural resources managers. Nowadays, it is commonly expected that these services must be based on information that includes an accurate assessment of its uncertainty. Stream discharge, the basic hydrological variable, is no exception, yet most measurements are still reported as a value without any information on its associated un ...
A career in meteorology
This book is a brief introduction to a career in meteorology. For more information about qualifications, training and opportunities, you are invited to consult your career adviser or your local or national weather service.
International Cloud Atlas: Manual on the Observation of Clouds and Other Meteors
This Atlas describes the classification system for clouds and meteorological phenomena used by all WMO Members. The classifications also describe meteorological meteors other than clouds – hydrometeors, lithometeors, photometeors, and electrometeors.
The Atlas provides a common language to communicate cloud observations, and ensures consistency in reporting by observers around the world. It serves as a training tool for meteorologists, as well as for those working in aeronautical and maritime environments, and it has become popular with weather enthusiasts and cloud spotters.

Guide sur la mise en oeuvre de systèmes de gestion de la qualité pour les Services météorologiques et hydrologiques nationaux et autres prestataires de services concernés
Le présent document a pour objet de donner les indications nécessaires pour élaborer et mettre en oeuvre un système de gestion de la qualité afin de garantir et d’améliorer la qualité des produits et services fournis par les Services météorologiques et hydrologiques nationaux (SMHN). Il décrit par ailleurs en détail les mesures que tout organisme doit prendre pour obtenir la certification de conformité de son système de gestion de la qualité à la norme ISO 9001:2008 Système de management de la qualité – Exigences (ISO 9001) de l’Organisation internationale de normalisation (ISO).
Directives de l’OMM sur l’élaboration d’un ensemble défini de produits nationaux de surveillance du climat
La présente publication a pour vocation de définir les caractéristiques des produits qui figurent sur cette liste et qui peuvent être élaborés facilement et de la même façon par la plupart des pays, y compris ceux dont les ressources sont limitées et qui devraient ainsi pouvoir concentrer leurs efforts sur un petit nombre d’indicateurs pertinents aux applications multiples.
Directrices de la Organización Meteorológica Mundial sobre la generación de un conjunto definido de productos nacionales de vigilancia del clima
La finalidad de la presente publicación consiste en proporcionar especificaciones para esa lista breve de productos nacionales de vigilancia del clima, que prácticamente todos los países pueden producir de manera coherente y fácil. El hecho de disponer de una lista de productos nacionales de vigilancia del clima claramente definidos debería servir para que los países con menos recursos puedan concentrar sus esfuerzos en un número reducido de productos de gran aplicabilidad e interés.
Directives de l’OMM pour le calcul des normales climatiques
Le présent document traite avant tout des observations réalisées dans les stations météorologiques en surface. Toutefois, bon nombre des principes exposés ici s’appliquent également à d’autres formes de relevés, comme les observations aérologiques et les jeux de données obtenus à partir de plateformes mobiles ou de télédétection (satellites, radars ou bouées dérivantes par exemple). Comme les jeux de données obtenus par télédétection remontent le plus souvent jusqu'aux années 70, il est recommandé de leur appliquer, dans la mesure du possible, la période climatologique standard actuelle (1981- ...
WMO气候平均值计算指南
本文件侧重于地面气象观测站的观测资料。然而，许多原理同样适用于其它形式的观测资 料，包括基于移动或遥感平台（如卫星、雷达或漂流浮标）的高空观测资料和数据集。特 别是，鉴于许多关键遥感数据集始于20世纪70年代，因此，建议尽可能将目前的标准气候 平均期（1981–撰稿时的2010年）用于这些数据集，以使不同资料形式之间能够一致地进 行比较。许多原理还可用于包含位置或地区而不是地面气象观测站的不同数据集，例如面 积平均值或网格数据集中的点。

Руководящие указания ВМО по расчету климатических норм
В настоящем документе основное внимание уделяется наблюдениям со станций приземных метеорологических наблюдений. Вместе с тем многие принципы также будут действительны для других форм наблюдений, включая аэрологические наблюдения и комплекты данных с мобильных платформ и платформ дистанционного зондирования (например, спутников, радиолокаторов или дрейфующих буев). В частности, в связи с тем, что многие основные комплекты данных дистанционного зондирования берут свое начало в 1970 х гг., рекомендуется по возможности использовать в отношении этих комплектов данных текущий период климатологическ ...
Directrices de la Organización Meteorológica Mundial sobre el cálculo de las normales climáticas
El presente documento se centra en las observaciones realizadas en estaciones meteorológicas de observación en superficie. Sin embargo, muchos de los principios expuestos también serán válidos para otras modalidades de observación, incluidas las observaciones en altitud y los conjuntos de datos basados en plataformas móviles o de teledetección (por ejemplo, satélites, sistemas de radar o boyas a la deriva). En particular, dado que numerosos conjuntos de datos de teledetección claves empezaron a elaborarse en el decenio de 1970, se recomienda, cuando ello sea viable, el uso del actual período d ...
