The Sun, The Earth, and Near-Earth Space
While solar radiation enables and sustains life on Earth, it also produces “space weather” that can profoundly impact different technologies, including telecommunications, satellite navigation, and the electric power grid. Solar flares can produce x-rays resulting in radio blackouts that block high-frequency radio waves. Solar Energetic Particles can penetrate satellite electronics and cause electrical failure. Coronal mass ejections (CMEs) can cause geomagnetic storms that induce ground currents and degrade power grid operations, sometimes catastrophically. The Sun, The Earth, and Near-Earth ...

Использование метеорологических данных могло бы поднять уровень готовности почтовых служб
«Ни снег, ни дождь, ни жара, ни ночной мрак не остановит этих гонцов от быстрейшего завершения назначенного пути». Эта фраза, выгравированная на стене здания почтового отделения имени Джеймса А. Фарли в Нью- Йорке, стала неофициальным девизом, отражающим надежность почтового обслуживания. Тем не менее в силу сильной разветвленности сетей и зависимости от основной инфраструктуры на работу почтовых служб могут оказывать большое влияние бедствия, особенно те, которые связаны с природными метеорологическими опасными и экстремальными явлениями.

Bulletin, Vol. 64(1). WMO, 2015Some 842 million people worldwide cannot afford to eat adequately and are chronically hungry. The links between food insecurity and poverty are clear. Factoring weather and climate information into agricultural decision-making has optimized agricultural production in many countries. However, in developing countries – where most smallholder farms are rain-fed – access to weather and climate information to guide decision-making is limited. Governments should view such information, crucial to farmers, as a means of alleviating poverty and hunger.

Rescue, Archive and Stewardship of Weather Records and Data
Data repositories and archives play a critical role as the source for the observational data used in the study of weather and climate. After over two centuries of recording observations on paper, observations in the last 20 years have mostly been collected digitally. Repositories around the world now have a mix of data on physical media, such as paper and microfilm, and digital media such as computer disks, magnetic tapes and DVDs. There is risk of data loss regardless of storage media. Repositories must identify, appraise, acquire, archive and migrate data to new technologies to make it avail ...

The Future of the Weather Enterprise
At a time when the impacts of weather and climate are still growing dramatically, it is important to look for strategies to strengthen the science and technology that have resulted in substantial improvements in the skill of weather predictions and services over the past four decades. It was not that long ago – when many baby-boomers were just entering the workforce – that accurate, reliable forecasts did not extend beyond 24 hours. Today, high-quality 5 to 7 day forecasts are the norm. This improvement has resulted in lives being saved and avoidable damage and economic impacts being averted. ...
Introduction to Meteorological Charting
This lesson provides a brief overview of surface and upper-air data and how these data are plotted on meteorological charts. The content introduces various charting and reporting techniques, including station models, contour analyses, streamlines, and upper air maps. Examples cover both the Northern Hemisphere and Southern Hemisphere and provide learners with opportunities to practice recognizing frequently used weather symbols. Supplemental materials include three Weather Symbol Identification drills. Completing these drills may require approximately 1-1.5 hours above the length of time estim ...
Introduction to Tropical Meteorology, 2nd Edition: Chapter 6 Vertical Transport
This chapter examines vertical transport of heat, moisture, momentum, trace gases, and aerosols, including the role of tropical deep convection and turbulence. Diurnal and seasonal variations in surface fluxes and boundary layer depth are examined. The boundary layer is compared over the ocean, humid, and dry tropics, including its role in dispersing chemicals and aerosols. Boundary layer clouds are examined in terms of their connection to sub-cloud layer properties. Comparisons are made between heat and moisture transport under a variety of convective modes such as mesoscale convective system ...
Assessing Agricultural Risk in Africa Using Satellite Data and Land Surface Models
Droughts pose a major risk in most African countries including Ghana where agricultural activities are heavily dependent on rainfall. Efforts at assessing droughts and providing decision support tools to farmers are hampered by a lack of rainfall and other meteorological data over many parts of Africa. Satellite based rainfall measurements have been suggested to fill the rainfall data gaps over Africa to enable effective assessment of droughts. Traditional methods of assessing droughts have been based on statistical formulations that relied mostly on precipitation. This approach to assessing d ...
Arctic drives new era in climate and weather services
The Arctic is changing. Melting sea ice, thawing perma¬frost and a greening tundra are some of the consequences of Arctic temperatures that have been higher in the past few decades than at any other time over the past 2000 years. Unanticipated alterations in weather patterns and ocean currents are driving changes both on land and in the oceans.
WMO Guidelines on Multi-hazard Impact-based Forecast and Warning Services
Improving the understanding of the potential impacts of severe hydrometeorological events poses a challenge to NMHSs and their partner agencies, particularly disaster reduction and civil protection agencies (DRCPAs). These Guidelines establish a road map that identifies the various milestones from weather forecasts and warnings to multi-hazard impact-based forecast and warning services.
For completeness, these Guidelines also describe the ultimate step of forecasting actual impacts, although it is recognized that this is a highly sophisticated exercise, requiring strong collaboration w ...
Valuing Weather and Climate : Economic Assessment of Meteorological and Hydrological Services
World Meteorological Organization (WMO) ; World Bank the; United States Agency for International Development (USAID); et al. - WMO, 2015 (WMO-No. 1153)The review of all past and current SEB analysis performed for this publication indicates that properly planned investments in hydrometeorological services provide significant benefits relative to their costs. While the publication attempts to capture the currently available wealth of experience and expertise across different contexts, it is not the end point for developing global knowledge on SEB analysis of hydrometeorological studies. Indeed, as we move to implement new global commitments on sustainable development goals, climate change adaptation and disaster risk reduction, interest in kno ...
Conference report - Conference on the Gender Dimensions of Weather and Climate Services
The Conference on the Gender Dimensions of Weather and Climate Services was a landmark international forum addressing how to equally empower women and men to build safer, stronger and more resilient societies through the provision and use of gender-sensitive weather and climate services. The Conference represented the contribution of the World Meteorological Organization (WMO) and its partners to the review of implementation of the Beijing Declaration and Platform for Action 20 years after its adoption. It also provided recommendations to enrich the development of the post-2015 disaster risk r ...
