Climate Variability and Change for Water Resources Management - International Edition
Climate is changing at unprecedented rates in recorded history. A variety of lines of evidence demonstrate that climate change is likely to affect the hydrologic cycle and thus create new challenges in water management. This requires that climate change information be included in water and water-related resources planning, operations, and management. Climate Variability and Change for Water Resources Management - International Edition describes the terminology, global evidence, regional manifestations, and basic science of global climate variability and anthropogenic change, with a focus on wa ...
TsunamiReady: Guidelines for Mitigation, Preparedness, and Response
The TsunamiReady® program began in 2001 to promote tsunami hazard preparedness and improve public safety before, during, and after tsunami emergencies. In 2015, the National Weather Service updated the TsunamiReady Guidelines based directly on emergency management principles and with input from the social sciences. This training provides an overview of the 2015 guidelines, which are focused on mitigation, preparedness, and response. The training will equip community officials and others interested in becoming TsunamiReady with strategies for streamlining their implementation of the guidelines. ...
Sea Level Change: Datums and Terminology
This lesson addresses how sea level is determined and applied. It starts with a general discussion of the surfaces that form the basis of measurement, called datums, then looks more closely at the vertical datums that form the basis of height measurements. We cover tidal datums in more depth, including the different datums, their extent, period of record (called a tidal epoch), and common applications. We conclude with a look at some data resources for tidal datums and sea level trends.
Sea Level Change: Basics
This lesson describes the physical processes, both natural and human-induced, that lead to changes in sea level. The processes described include climate induced changes in ocean heat content and volume, natural oceanic cycles, and both natural and human-induced changes in coastal land elevation. The learning is enhanced with rich graphics and periodic questions.
Best Practices in Tropical Cyclone Briefings
Crafting clear, concise and effective messages focused on customer needs is a crucial skill in every decision-support situation. Tropical cyclones that threaten a coastline have the potential to inflict devastating damage to communities and communicating relevant weather information will assist decision-makers in their plans and preparation work. This lesson examines how to effectively prepare for the hurricane season and then focuses on how best to support NWS partners through meteorological briefings during tropical cyclone events. Basic familiarity with probabilistic forecast guidance is re ...
Ocean Acidification
The chemistry of the world’s oceans is changing. Ocean acidity is creeping upward, a result of rising atmospheric carbon dioxide. The added carbon dioxide depletes seawater of carbonate, a chemical constituent of minerals that form the shells and structures of animals including corals, molluscs, plankton, and others. The accelerating impacts are expected to reverberate through the marine food web. Most people are unaware of ocean acidification and its expected impacts. This lesson will educate policy makers and university students about its causes and consequences. The lesson explains the chem ...

Sea Breeze
Miller Jack - WMO, 2016"This is my first time-lapse film I decided to put together. All scenes are shot in Florida from April - September 2016. This film is meant to showcase Florida's weather pattern from a stray shower to a fierce severe warned thunderstorm.
Through that time period, I had taken over 149,000 photos between the two cameras for this project. Less than half were used for the final production. Overall editing took about 2 months and was really because of the music choice as I had switched songs half way through the project.
***Technical*** - Equipment used was a Canon 6D ...
Ocean, climate and weather: the role of the World Meteorological Organization
When it comes to the weather, most of us think only about what is happening in the atmosphere. If we ignore the ocean, however, we miss a big piece of the picture: covering some 70 per cent of the Earth’s surface, the ocean is a major driver of the world’s weather and climate. The ocean is also a major driver of the global economy, carrying more than 90 per cent of world trade and sustaining the 40 per cent of humanity that lives within 100 km of the coast. Recognizing this, national weather agencies and researchers regularly monitor the ocean, model how it affects the atmosphere and deliver m ...
Rainfall Variability over Zimbabwe and its relation to large-scale atmosphere-ocean processes
Mamombe Vimbai - 이화여자대학교 대학원, 2016For Zimbabwe, where rain fed agriculture is the backbone of the economy, the importance of accurate rainfall seasonal forecasts cannot be overemphasized (Makarau and Jury, 1997). In fact, extremes in interseasonal variability of rainfall can significantly complicate human livelihoods. In addition, there have been predictions of increased precipitation variability and hydro-meteorological hazards such as floods, droughts, and erratic rainfall due to global warming (Field et al., 2014; Mushore, 2013a). Thus, detailed understanding of the major contributors to the rainfall variability over Zimbab ...

Interview: Vladimir Ryabinin, Executive Secretary of the Intergovernmental Oceanographic Commission (IOC) of UNESCO
Bulletin, Vol. 64(2). WMO, 2015Vladimir Ryabinin of the Russian Federation was appointed as the new Executive Secretary of the Intergovernmental Oceanographic Commission (IOC) of UNESCO at the level of Assistant Director-General (ADG) of UNESCO on 1 March 2015. Mr Ryabinin went to IOC from WMO, where he was a Senior Scientific Officer in the World Climate Research Programme (WCRP) from 2001 to 2015. His years of experience with WMO will surely benefit the close cooperation between the two organizations. The Bulletin is pleased to introduce him to our readers through the interview below. 1

Progress in Observing and Predicting ENSO
Bulletin, Vol. 64(1). WMO, 2015Governments, private companies and individuals are demanding ever more sophisticated climate services, as manifested by the Global Framework for Climate Services (GFCS). But parts of the ocean observation network – paramount to the delivery of climate services – are at risk, and the evolution of climate prediction systems is not keeping pace in terms of accuracy and reliability
JCOMM Technical Report, 63. Recommended Algorithms for the Computation of Marine Meteorological Variables
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC); United Nations Educational, Scientific and Cultural Organization (UNESCO) - WMO, 2015This publication presents a summarized version of the WMO No-8 information, focusing on the instruments used by the VOS, but breaks new ground in making specific recommendations (including providing software modules and test validation cases) on the algorithms to be used to compute “derived” variables.

JCOMM Technical Report, 84. Final report, JCOMM Pilot intercomparison project for seawater salinity measurements
World Meteorological Organization (WMO) ; Intergovernmental Oceanographic Commission (IOC) - WMO, 2015The Pilot Inter - comparison Project for Seawater Salinity Measurements is organized by The Joint WMO - IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM) and undertaken by the Regional Marine Instrument Center for the Asia - Pacific Region (RMIC/AP). As the first inter - comparison project under JCOMM framework in history, the purpose is of understanding the overall quality level of salinity measurements of JCOMM Members/Member States and observation programmes, identifying the differences an d promoting the expertise of salinity measurements.
Understanding Marine Customers, 2nd Edition
Understanding Marine Customers, 2nd edition, introduces the different marine forecast customers and discusses what forecast information they need to know and why they need to know it. A better understanding of the needs of the marine forecast customer will lead to better daily forecasts. The 2nd edition expands upon marine customer base to include more nearshore users, such as beachgoers, surfers, and sea kayakers.
