Guide de l'assistance météorologique aux activités maritimes
La connaissance des conditions météorologiques tient depuis toujours une place essentielle en matière de sécurité et d’efficacité appliquées aux activités maritimes, notamment le transport et la pêche. Au début du XXe siècle, avec l'apparition de la télégraphie sans fil, il devient possible d'établir des communications régulières entre les navires et la côte; c’est le commencement des émissions météorologiques pour la navigation maritime. La première Convention internationale pour la sauvegarde de la vie humaine en mer (Convention SOLAS) préconisait que la radiodiffusion de renseignements mété ...

Basic Satellite Imagery Interpretation
This lesson teaches the basics of satellite image interpretation to forecasters, meteorology students, and other interested learners, with an emphasis on the African region. It begins by briefly describing visible, infrared, and water vapour channels, as well as RGBs and derived products. From there, it teaches learners how to interpret clouds and surface features using various channels and products. This sets the stage for the final section, where learners practice identifying features using assorted imagery and products. The lesson uses Meteosat Second Generation imagery over Africa and, to ...
Dam Failure Concepts and Modeling
This lesson provides an in-depth case study to illustrate principles of dam failure modeling and examines some of the critical data inputs and outputs. Output is provided from the U.S. Army Corps of Engineers HEC-RAS model for simulated failures of a large dam. Several simulations are presented that show the impact from varying the size of the breach and the time it takes the breach to fully develop. The lesson also summarizes several infamous large dam failures from around the world and the impacts from other factors are such as reservoir shape and size, the age of the dam, and the material u ...
Met 101: Introduction to the World's Oceans
This short lesson provides an overview of the world's oceans, including information about geography, physical properties, major currents, and the effects of oceans on weather and climate. Brief information about wind waves, swell, and tides and the drivers of each of these phenomena are included along with an introduction to ocean measurements.
High-Frequency Radar: Supporting Critical Coastal Operations with Real-time Surface Current Data
Produced in collaboration between NOAA’s National Ocean Service (NOS) US Integrated Ocean Observing System (IOOS) Program Office and The COMET Program, this video explains how high-frequency radar (known as HF radar) is used to provide detailed information in real-time on coastal ocean surface currents. It describes the important role that HF radar products play in critical coastal operations such as hazardous spill response. Finally, it covers basic capabilities and strengths of HF radar as well as how to access coastal current data. Coastal decision-makers and managers across all levels of g ...
Communicating Winter Weather Surface Impacts
This lesson will introduce National Weather Service (NWS) forecasters to the benefits of pre-season coordination in understanding the critical needs of decision-makers, particularly the state and local Departments of Transportation (DOTs). The strategies used by DOTs to mitigate road impacts during the winter and how the NWS can best support their needs are also discussed. Learners will gain insight into the common methods of collaboration between the NWS and DOT, and the different types of winter weather events in which they work together. Learners will also practice communicating winter weat ...
Reservoir Pool Elevation: Considerations for Long-term Asset Management and Planning
Long-term management of critical water resources infrastructure needs to incorporate projected changes to environmental conditions. Reservoirs form the heart of water resource assets. Long-range plans for the repair, replacement, maintenance and renovation of these facilities depend on accurate projections of reservoir pool elevations. Environmental conditions, in turn, dictate the magnitude and timing of inflows and outflows from reservoirs, and thus the resulting water surface elevation. This lesson explores the factors that affect reservoir pool elevation and the considerations and challeng ...
Met 101: Introduction to the Atmosphere
This lesson provides an overview of Earth’s atmosphere, its vertical structure, the fundamental forces acting on air, and how the atmosphere's composition affects the colors we see in the sky. The lesson also includes information about how Earth receives energy from the Sun as solar and infrared radiation, and the mechanisms for transferring heat around the globe. Learners will be introduced to the components of Earth’s water cycle, and also briefly explore the main types of systems used to observe the atmosphere.
Good practice guidelines for water data management policy : world water data initiative
Bureau of Meteorology ; World Meteorological Organization (WMO) - Australian Bureau of Meteorology, 2017These guidelines acknowledge that it is difficult to gather support for and then prosecute actions that are disruptive to the status quo and requiring considerable public investment. It is stressed that planning the water data reform journey is every bit as challenging as implementing the reforms themselves. Accordingly, these guidelines conclude with a recommended series of steps to get started in reforming water data management arrangements. Guidance is provided for (1) taking stock of current policy settings, (2) preparing the case for reform, (3) positioning for effective implementation an ...

Marine Seminar: WMO and UNESCO/IOC
On Wednesday May 3 from 10am to 12.30 in the WMO Press Room, there will be a Marine Seminar by both WMO and visiting staff from UNESCO’s Intergovernmental Oceanographic Commission (IOC).
The Seminar will be chance for exchange of information and discussion between the two agencies, as outlined in the attached programme. From the UNESCO-IOC, Dr Albert Fischer, Dr Salvatore Arico and Dr Thorkild Aarup will share information about IOC programs relevant for WMO, and vice versa, WMO staff will share information on their marine work here.
UNESCO IOC is an important part ...
Analysis inter decadal of climate variability facing projections of the CMIP5 models and its involvement in the agricultural production of Venezuela
Agriculture is the largest employer in the world and is probably the most dependent on the climate of all human activities. In recent years there have been events that have put in evidence the vulnerability of global food security to major meteorological phenomena, both in global agricultural markets and the world economy. The food price crisis and the subsequent economic crisis reduced the purchasing power of large segments of the population in many developing countries, which seriously reduced their access to food and thus undermined their food security. During the years 2009 and 2010 in Ven ...
