international weather modification definition

A major aim of the work is to clarify the microphysical structures of clouds suitable for seeding and their occurrence frequency over the eastern mountain areas of the UAE. Despite decades of research, deep skepticism still surrounds cloud seeding due, in part, to the challenge of verifying the efficacy of the technique – establishing cause and effect – given the complexity and variability of weather systems. The Environmental Modification Convention (ENMOD), formally the Convention on the Prohibition of Military or Any Other Hostile Use of Environmental Modification Techniques is an international treaty prohibiting the military or other hostile use of environmental modification techniques having widespread, long-lasting or severe effects. Our solution is an addendum to the international weather warfare ban requiring two things: • TRANSPARENCY: a worldwide requirement to give 48 hour notice before modifying or experimenting in our sky or surrounding atmosphere. Anything that alters clouds can affect seeding. Can a State be held liable to another State or to citizens of another State for damage caused by (a) the State's own weather modification activities; ( “We are working to better evaluate, and ultimately improve, the effectiveness of precipitation enhancement in arid and semi-arid regions through a sound scientific research consisting of data analysis, laboratory experiments, field observation and numerical modelling,” he says. For example, volcanic eruptions have injected particles into stratosphere that have reduced temperatures globally for 2 to 3 years after the eruptions (e.g. The salt helps water droplets to collide and produce rain. About Weather Modification LLC dba Weather Modification International (WMI): WMI is the world-leader in atmospheric chemistry, pollution and weather research, weather forecasting and modeling, and weather modification programs. Over the last 10 years, cloud seeding experiments have benefited from advances in numerical models that can simulate seeding more accurately, as well as improved observational tools to understand the physical processes in clouds due to seeding. a. The WMA cultivates a better understanding of weather modification techniques among program sponsors, program operators, and the scientific community. “The outcome of this statistical randomization process must then be supported with an analysis that validates the original cloud seeding operations.”. These tools include more precise satellite capability and ground-based and airborne dual-polarization radars that can better measure precipitation size. Examples of weather modification in a sentence, how to use it. “What you add may not have the desired effect in your vicinity, but by being transported along might have undesired effects elsewhere.”, But above all, it’s all about the clouds. Since the discovery in the late 1940s that crystals of silver iodide can form ice crystals in some water vapor, scientists have been working to understand how to alter the way water forms and moves within a cloud. They are an especially attractive target for cloud seeding because high-elevation snowpacks can store water for a region year-round. In these regions, clouds form from air flowing over mountains. This section summarizes the current knowledge of the physical processes affecting weather modification as a result of changes in land use, aerosol, and gas emissions. Weather modification also does not refer to climate changecaused by industrial and natural sources of aerosols … The location of the clouds is also highly significant. Award Winners of the UAE Rain Enhancement Programme - The United Arab Emirates announced the winners of the Rain Enhancement Programme on 17 January. Weather modification and control program" means the research, development, licensing, and permitting and other associated activities to be administered by the Texas Department of Licensing and Regulation. When most people look up they see clouds. “There is no one-size-fits-all solution,” she says. With the high cost of desalination, the UAE has been conducting cloud seeding as a possible lower-cost alternative. Bolstered by an international drive for research and funding to secure water resources, scientists are cautiously working to modernize rainmaking for the 21st century. It has also been building a weather modification … New tools are enabling meteorologists to study and understand clouds and their modification with greater precision than ever, while new technologies such as nanotechnology are expanding the possibilities for the field. (4) For the purposes of this thesis, weather modification will be defined as an intentional act to modify the weather. It focuses on liability under international law, and emphasizes issues related to cloud-seeding to affect precipitation and to hurricane modification. “The main cloud seeding methods provide centers for drops and ice crystals to form on,” Bruintjes says. “Still, reliable campaigns remain costly, requiring numerous test clouds, both seeded and not,” she says. “If these particles already exist in optimal size and concentration in some regions of the world, cloud seeding would not have an impact.”. Like in a medical experiment, where no two people are alike, “no cloud is the same as another, and there are many factors that can play a role in the development of precipitation in a cloud.”. Without clouds, these technologies are powerless. UAE Research Programme for Rain Enhancement Science. Humans have long sought to purposefully alter such atmospheric phenomena as clouds, rain, snow, hail, lightning, thunderstorms, tornadoes, hurricanes, and cyclones. The UAE Program team is working with awardees over the next three years to help them implement their research projects. WEATHER MODIFICATION: cloud seeding, atmospheric services - Weather Modification, Inc. Part of finding the “right” clouds depends of the temperature. Using nanotechnology, researchers could potentially create new chemicals for cloud seeding that better mimic the crystalline structure of ice at a nanoscale. For all weather modification – intentional or not – it is important to remember that “the atmosphere has no walls,” Flossmann says. Al Mandoos says he is proud of the “UAE as a global hub that develops the best technologies that contribute to the water shortage solutions.”. An Act To End Atmospheric Experimentation Without Notification. “Recently, seeding has been proposed as a climate mitigation strategy, to increase cloud brightness and increase the part of solar radiation reflected into space,” Flossmann says. Weather modification and control" means changing or controlling, or attempting to change or control, by artificial methods the natural development of atmospheric cloud forms or precipitation forms that occur in the troposphere. Weather modification has been something that the United States and many other governments have been working on for years including Project Stormfury which is a U.S. project that focused on controlling the storm paths of hurricanes. Warm or cold, polluted or clean, over a mountain or a field, a cloud’s characteristics are key to the success or failure of cloud seeding efforts. Measuring the impact of cloud seeding initiatives is challenging. The US$5 million funding went to Professor Giles Harrison of the University of Reading, Professor Hannele Korhonen of the Finnish Meteorological Institute and Dr Paul Lawson of SPEC Inc. Lisa M.P. As part of its rain enhancement program, the UAE is working to lead the way for greater investments and technological advancements in weather modification. One such group is Murakami’s research team, which received a 2015 grant award from the UAE Research Programme for Rain Enhancement Science. Al Mandoos of the UAE points to the WMO Guiding Principles for the Planning of Weather Modification Activities as an important resource for countries looking to improve water security. “Nobody can make a cloud or chase away a cloud.”, “The basic concept of weather modification, especially precipitation enhancement, is to find a rate-limiting process related to the conversion of cloud water to precipitation in natural clouds, and to bypass it with a minimum level of artificial stimulation,” says Dr. Masataka Murakami of the Institute for Space-Earth Environmental Research at Nagoya University in Japan. Geoengineering and weather manipulation is nothing new but has been around for over 150 years. The WMO report offers caution for such global-scale efforts, pointing out the historical difficulties in proving cause and effect for seeding interventions at the local scale. 3 The definition of weather modification used in the I966 Report of the National Academy of Sciences will serve us as a standard here: The subject of weather and climate modification is concerned with any artificially produced changes in the composition, behavior, or dynamics of … “Although not perfect, it has been a great step forward,” Bruintjes says. It is an honor to transmit herewith to the National Science Foundation the report of the Special Commission on Weather Modification, authorized The 2015 WMO Statement on Weather Modification also discusses weather modification techniques to suppress hail and disperse fog, and it mentions recent interest in climate engineering. According to its director, Alya Al Mazroui, the program has two goals: to boost research in rain enhancement worldwide, and to increase rainfall in the UAE and other arid and semi-arid regions in the world. Define Weather modification and control. Their goal is to achieve the ability to affect the weather over a 2.1 million square mile area, an area one and a half times the size of their regional foe, India. In an analysis of results from the initial 2005-2009 experiment, researchers found a positive, but not statistically significant, impact of seeding on snowfall; however, they found the targeting of the seeding efforts “unequivocally successful”, with levels of silver iodide higher in seeded areas compared to unseeded ones. means changing or controlling, or attempting to change or control, by artificial methods the natural development of atmospheric cloud forms or precipitation forms that occur in the troposphere. Further, understanding anthropogenic effects on weather is important to improve short-range and longer term weather predictions. Weather modification, which could also be called “weather intervention,” is the intentional alteration of the composition, behavior, or dynamics of the atmosphere occurring over a specified area and time period to accomplish a particular goal (NRC, 2003). The United States Code is meant to be an organized, logical compilation of the laws passed by Congress. The US$ 5 million UAE Research Programme for Rain Enhancement Science launched in 2015 as an international initiative to advance the research and technology of rain enhancement. “As we get better at weather prediction, we can better predict a change.”. China this week revealed plans to drastically expand an experimental weather modification program to cover an area of over 5.5 million square kilometers (2.1 million square miles) -- …
