Since its inception, WWR has been produced by three different institutions: the Smithsonian Institution (1927, 1934, 1947); the U.S. Weather Bureau (1959, 1967); and the U.S. National Oceanic and Atmospheric Administration (NOAA; 1983, 1991, 2005). The current edition will also be produced by NOAA. It addresses the 2001-2010 period, consistent with WMO Secretariat guidance. However, the previous edition lacked data for many countries, posing an impediment to climate monitoring and assessment activities because of the decline in station coverage starting in 1991. Congress XVI, Geneva 2011, emphasized the importance of updating the World Weather Records continuously. It requested Members to complete the data sets for WWR 1991-2000 and submit WWR for 2001- 2010.

The CBS/OPAG-PWS Expert Team on Communication, Outreach and Public Education Aspects of PWS (ET/COPE) therefore decided to collaborate with the ET/DPM to prepare a set of guidelines, for use by NMHSs, for the establishment of such formal agreements between a National Meteorological or Hydrometeorological Service (NMS) a ...
PermalinkWhy are demand and renewal rates for micro-insurance so low despite the important protection against disasters it may offer? To address the puzzle this paper provides a selective overview of the current state of research on demand from farmers for risk micro-insurance mostly associated to lack and excess of rainfall (drought and flood). It first looks at the theoretical research and then reviews the empirical evidence on the factors influencing risk attitude and demand for disaster insurance from low-income farmers.
PermalinkThis issue travels to Ceará State in northeastern Brazil, an area that faced increasingly frequent drought conditions, and the efforts of community organizations to develop strategies to minimize the negative impacts from droughts and adapt their livelihoods in such a way that makes families more resilient. It describes how the residents, using techniques to conserve water, enhance agricultural practices, and diversify income sources, have managed to mitigate the risk of drought.
PermalinkThis issue examines the desert locust, a pest that affects the lives of millions of people in more than 65 countries throughout Africa, the Middle East, and Southwest Asia, an area that represents about 20 percent of the earth’s surface. It presents the case of Mauritania, one of several countries in West Africa, the Horn of Africa, and the Middle East to benefit from the U.N. Food and Agriculture Organization (FAO)’s locust prevention system known as the EMPRES Program, to which USAID and other donors contribute.
PermalinkThis edition focuses on the potato as a targeted disaster risk reduction effort in western Afghanistan. By helping farmers adapting how they handle the potatoes, it describes how the USAID program is enabling farmers to grow more food to last through the cold winter months and even have a chance to sell surplus produce when prices are favorable to them. It demonstrates that a more resilient livelihood means less vulnerability to weather-related and economic shocks.

PermalinkNational Drought Mitigation Center ; United States Department of Agriculture (USDA) - University of Nebraska-Lincoln (UNL), 2012This guide is designed to help rangeland managers to better prepare for and manage drought. For ranchers in the United States, drought can be defined as too little soil moisture to meet the needs of dominant forage species during their rapid growth windows. The longer you wait to make decisions, the fewer options you will have available to you and producers who focus on increasing flexibility and maximizing the health of resources are more likely to find solutions during drought that minimize painful decisions with limited resources. Accordingly, having a plan will help producers get through a ...

PermalinkSteduto Pasquale; Hsiao Theodore C.; Fereres Elias; et al. - FAO, 2012 (FAO irrigation and drainage paper-No. 66)Food production and water use are inextricably linked. Water has always been the main factor limiting crop production in much of the world where rainfall is insufficient to meet crop demand. With the ever-increasing competition for finite water resources worldwide and the steadily rising demand for agricultural commodities, the call to improve the efficiency and productivity of water use for crop production, to ensure future food security and address the uncertainties associated with climate change, has never been more urgent.

PermalinkIn Europe, it can be estimated that hydro-meteorological information and early warning systems save several hundreds of lives per year, avoid between 460 million and 2.7 billion Euros of disaster asset losses per year, and produce between 3.4 and 34 billion of additional benefits per year through the optimization of economic production in weather-sensitive sectors (agriculture, energy, etc.). The potential for similar benefits in the developing world is not only proportional to population, but also to increased hazard risk due to climate and geography, as well as increased exposure to weather ...

PermalinkWorld Meteorological Organization (WMO) ; WWRP/WGNE Joint Working Group on Forecast Verification Research (JWGFVR) - WMO, 2012Cloud errors can have wide-reaching impacts on the accuracy and quality of outcomes, most notably, but not exclusively, on temperature. This is especially true for weather forecasting, where cloud cover has a significant impact on human comfort and wellbeing. Whilst public perception may not be interested in absolute precision, i.e. whether there were 3 or 5 okta of cloud, there is anecdotal evidence to suggest strong links between the perceptions of overall forecast accuracy and whether the cloud was forecast correctly, mostly because temperature errors often go hand-in-hand. It is therefore ...

PermalinkThe purpose of this unit is to introduce the online version of the Intermediate Wildland Fire Behavior, S-290 course. The unit discusses the overall course objectives, the content covered in the twelve units comprising this course, course navigation, and the contributors to this effort.
PermalinkS-290 Unit 6: Atmospheric Stability introduces the processes related to stable and unstable atmospheric conditions and explains their impact on fire behavior. This Unit provides detailed information about how fire behavior is affected by stable and unstable atmospheric phenomena such as inversions and thunderstorms. The Unit also explains cloud formation and describes the usage of clouds and other visual indicators to recognize stable and unstable atmospheric conditions. The module is part of the Intermediate Wildland Fire Behavior Course "http://www.meted.ucar.edu/dl_courses/S290".
PermalinkTropical cyclones are the deadliest tropical weather systems. This chapter describes their seasonal and geographic variability and controls, decadal cycles, and history of naming conventions. Tropical cyclogenesis is explored in depth and the core and balance solutions for regions of the cyclone are examined. Intensity is considered in terms of inner-core dynamics, large-scale environmental controls, limits on potential intensity, satellite interpretation techniques, and classification by wind speed. Factors that influence motion are investigated. Extratropical transition is described in terms ...
PermalinkS-290 Unit 10: Fuel Moisture provides information about live and dead fuel moisture contents and their relation to fire behavior. Influences on fuel moisture and methods for estimating dead fuel and live fuel moisture in the field are summarized, and guidance is offered for assessing the potential fire danger based on fuel moisture and other fireline information. The module is part of the Intermediate Wildland Fire Behavior Course.
PermalinkThis chapter presents an overview of the major cycles dominating intraseasonal and interannual variability in the tropics. Characteristic atmospheric and oceanic patterns for each oscillation are presented and methods for tracking the evolution of these cycles are described. Observations and conceptual models of equatorial waves are presented. Classical solutions for equatorial waves are outlined and the effects of moisture on the expression of these waves are discussed. Since the tropics are not an isolated region of the globe, the impacts of these cycles on higher latitudes are also explored ...
