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 ...

UNESCO IOC is an important partner to the WMO, across a myriad of marine related activities including services, data and observations. Testament to this strong partnership and complementary work, is the fact that the former WMO Technical Commission for Marine Meteorology (CMM) was officially combined in 1999 with the IOC to form the WMO / UNESCO-IOC Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM). In addition, there are clear synergies between other IOC and WMO activities related to disaster risk reduction, polar regions, SIDS and capacity development.
This Seminar is also timely, ahead of the UN Ocean Conference (https://oceanconference.un.org/) which will be held in New York in June, during which both WMO and IOC will be represented.Language(s): English

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 ...

Progrès réalisés dans l’observation et la prévision du phénomène ENSO
Bulletin, Vol. 64(1). OMM, 2016Les gouvernements, les entreprises du secteur privé et les particuliers sont de plus en plus exigeants lorsqu’il s’agit de la qualité des services climatologiques, d’où l’importance du Cadre mondial pour les services climatologiques (CMSC). Cependant, certaines composantes du réseau d’observation de l’océan – pourtant essentielles à la prestation de ces services – risquent de se dégrader, et les systèmes de prévision climatique ont du mal à rester au fait des attentes croissantes quant à l’exactitude et à la fi abilité des services.1234

Statistical analysis of rainfall trend and water vapor distribution over the Central African Republic
To apprehend the temporal and spatial distribution of the rainfall over CAR, we computed thirty-three years (1981-2013) of monthly rainfall, relative humidity over the country divided into four (4) distinct sub-regions. Bearing different characteristics one to another, we found that Region 2 and Region 4 were having a statistical significant upward trend along the long term rainfall variation; meanwhile Region 3 was the one having a highest coefficient of variation on the yearly basis. The composite analysis showed that December, January and February were the months with higher frequency of va ...

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 ...

Operational Models Encyclopedia
The availability of numerical guidance from NWP models has been an important component of operational forecasting for decades. For many, the output from this numerical guidance was produced by a mysterious “black box”. Rules for using and adjusting the guidance for operational forecasters were often subjective “Rules of Thumb” based on experience rather than based on quantitative analysis. To open up this “black box”, we produced this web-based “Operational Models Encyclopedia” linking both generic information on how NWP models work, and specifics on physical parameterizations, dynamics, and d ...

Extreme High Swell Events on the Moroccan Atlantic Coast
High swell events can develop far from the coast under cyclonic conditions, and take several days to travel to land. If early warnings are not issued, they can take an area by surprise and have a devastating impact. This lesson aims to improve the ability of marine forecasters to forecast extreme marine events related to high swells. It does so by providing background information on winds and waves, and presenting a process for monitoring and forecasting high swell events using a variety of data. These include ASCAT scatterometer wind data and the ECMWF Extreme Forecast Index (EFI) product, wh ...

Using ASCAT Wind and Other Data in Marine Forecasting
This case study lesson demonstrates the use of scatterometer wind and, to a lesser extent, altimeter significant wave height products in marine forecasting. A brief introduction to cold fronts and their impact on weather and sea state conditions sets the stage for the main part of the lesson, the case study. The case follows the passage of a cold front over the South Atlantic Ocean on 23 and 24 November 2013 when the Polarstern research vessel was transiting the area. Learners use ASCAT wind and Jason significant wave height data to help determine current conditions and evaluate GFS and WAVEWA ...

Instability Indices and Heavy Rainfall Forecast in a Maritime Environment
Forecasting heavy rainfall associated with in-situ convective cloud development over small island states is a challenge in operational forecasting as not all numerical models are able to resolve convection at such small scales. Forecasting of such phenomena is mainly based on prevailing local conditions and the use of a plethora of thermodynamic indices derived from the local sounding. This study is an effort to assess the suitability of the different available indices, hereafter referred as traditional indices, to forecast heavy rainfall from local convection, commonly known as pure sea breez ...

Recommendations for the post-2015 Hyogo Framework for Action (HFAII) : calling for increased attention to the need for integrated water and wetland management to reduce disaster risk
This paper summarizes a set of recommendations on wetlands for inclusion in the post-2015 HFA, calling for increased attention to the need for integrated water and wetland management to reduce disaster risk. It argues that emerging trends in disaster risks underline the need to consider the role of water and wetland management as important elements of disaster risk reduction and risk management strategy as wetlands are crucial in regulating the water cycle by reducing peak flood flows, storing excessive precipitation or recharging groundwater.

Primary Influences on Water Temperature for Inland Streams
This lesson explores the primary influences, or drivers, on water temperature of inland streams and rivers. We use a simulated flight, or flyover, where we look down at the features of the South Boise River in Idaho. An unregulated as well as a regulated reach of the river are explored (above and below the Anderson Ranch Reservoir), with a look at cross sections of the river and its environment at key locations during the flyover. We explore how environmental factors (climate, geography, stream morphology) impact water temperatures. Then, after defining the factors that affect water temperatur ...
