Flood Management Tool Series, Technical Document, 23. Health and Sanitation Aspects of Flood Management
Flood events are known for their profound capacity to positively or negatively affect humans. Floods improve overall human well-being by providing services such as groundwater recharge, surface-water replenishment, soil-fertility enhancement and a general increase in the value of social–ecological systems. Equally, however, flood events pose a series of diverse health threats, ranging from contaminated water sources to decreased agricultural productivity, especially when communities are vulnerable and lack the capacity to effectively respond to, and recover from, the adverse effects of floods. ...
Flood Management Tool Series, Technical Document, 22. The role of the media in flood management
Communication is the imparting or exchange of information between individuals or groups through a common system of symbols, signs or behaviour (Merriam-Webster, 2013a; Oxford Dictionaries, 2013). In recent decades, different conceptual models have been developed to explain the process of human communication. One of the best representations of the flow of information in flood communication is the Interactional Communication Model proposed by Schramm (Schramm, 1954).
Flood Management Tool Series, Technical Document, 21. Effectiveness of flood management measures
It is not enough to assert—to an elected official, a regulator, a donor organization or the taxpayer—that one’s organization is doing an effective job of flood management. One also has to be able to provide a credible answer to the question: “How do you know?” 2 There is a multiplicity of flood management activities that can be pursued by a plethora of government jurisdictions, government agencies, NGOs, private and volunteer groups— independently, in cooperation, in competition. These activities may include: constructing flood prevention infrastructure; rebuilding houses, buildings and infras ...

دلیل أدوات وطرق رصد الأحوال الجویة
وصدرت الطبعة الأولى من دلیل أدوات وطرق رصد الأحوال الجویة (مطبوع المنظمة رقم 8) في عام 1954 وكانت تتألف من اثني عشر فصلاً. ومنذ ذلك الحین، ظلت مسألة التوحید القیاسي مصدر قلق ومن ھنا تواصل اللجنة استعراض محتویات .(CIMO) رئیسیاً بالنسبة لأنشطة لجنة أدوات وطرق الرصد الدلیل وتتأكد من أن عملیات التحدیث المنتظمة تشمل المواد الإرشادیة الحدیثة التي تعكس التطور السریع للتكنولوجیا وتنفیذھا في مجال أدوات وطرق رصد الأحوال الجویةIntroduction to Observing Oil from Helicopters and Planes
Aircrews and pilots are frequently the first to see oil spills on water. They provide critical eyes in the sky for U.S. Coast Guard (USCG) response teams and NOAA's Office of Response and Restoration. Oil spill responders use a common terminology for describing and reporting oil spills. This lesson teaches aircrews how to identify, describe, and report spills using that terminology. Misidentifying natural events as oil spills is a common, and sometimes expensive, mistake. This lesson also points out common false positives when trying to identify oil spills. While our primary audience for this ...Writing TAFs for Convective Weather, 2nd Edition
"Writing TAFs for Convective Weather, 2nd Edition" uses a severe thunderstorm event to illustrate techniques for producing an effective Terminal Aerodrome Forecast (TAF) following current National Weather Service directives. The unit offers guidance for developing TAFs for different types of convection and discusses how to concisely communicate logic and uncertainty in an aviation forecast discussion (AvnFD) or by other means. It also addresses the importance of maintaining an effective TAF weather watch and updating the TAF proactively.Satellite Feature Identification: Conveyor Belts
Conveyor belts highlight important atmospheric processes that can be advantageous for making forecasts. They can be used for identifying general temperature patterns, defining the extent of cloud cover, predicting moisture return, evaluating stability, forecasting wind gusts, pinpointing cyclogenesis, and understanding the three-dimensional structure of the atmosphere. For short-term forecasts, they can even augment NWP showing the three-dimensional structure and portraying the same information as equivalent or wet-bulb potential temperature and potential vorticity surfaces. Conveyor belts mak ...Tropical Cyclone Intensity Analysis
This lesson provides guidance for operational forecasters needing to combine different intensity methods to determine the intensity of a tropical cyclone. Each of the intensity methods is summarized, focusing on both strengths and weaknesses. These methods include the Dvorak technique, surface observations, scatterometry, the Advanced Dvorak Technique (ADT), microwave sounders (AMSU), SATCON, and subjective interpretation of passive microwave patterns. Consideration of the previous intensity estimate and forecast is also examined. Three case studies task the learner with combining the various ...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 ...EUMeTrain's Synoptic Textbook
This 190-page text, which is based on a series of university lectures, provides comprehensive information on synoptic meteorology. There's a general introduction to synoptics followed by chapters on tropospheric circulation, air masses, boundary layer and weather, wind fields, jet streams, vertical motions, high and low pressure, convective systems, numerical parameters in vertical cross sections, mid-latitude cyclones, the tropopause, and fronts. A number of the examples in the textbook are from Northern Europe. This resource is made available courtesy of EUMeTrain and is not produced, owned ...Quasi Geostrophic Vorticity Equation
This learning object/widget is designed for upper-level undergraduates or forecaster interns who want to apply their knowledge of the Quasi-geostrophic Vorticity Equation to forecast situations. The interactivity helps users see how each variable interacts within the equation and shows data for different phase shifts of 500hPa and 1000hPa heights. Instructors can use this learning object with their own question sets as well to build more understanding and application into their dynamics/synoptic courses.Introduction to Electromagnetic and Electro-Optic Propagation
This lesson describes the properties of electromagnetic and electro-optical radiation and how their propagation is affected by the atmosphere and weather. Atmospheric variables that affect EM propagation include temperature, moisture, pressure, and composition. These variables control processes including refraction, absorption, and scattering.Basics of Visible and Infrared Remote Sensing
This lesson presents the scientific and technical basis for using visible and infrared satellite imagery so forecasters can make optimal use of it for observing and forecasting the behaviour of the atmosphere. The concepts and capabilities presented are common to most international geostationary (GEO) and low-Earth orbiting (LEO) meteorological satellites since their inception, and continue to apply to both current and newer satellite constellations. The lesson reviews remote sensing and radiative transfer theory through a series of conceptual models. Discussions contain explanations of the di ...Climate Variability and Change Lectures, July 2013
