Download or read book Synoptic dynamic Precursors to Extreme Cases of Tropospheric Moisture Flux Convergence in the United States Midwest and Their Relationship to Precipitation written by Laura Twidle and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Midwest US is prone to receiving heavy precipitation events, including Mesoscale Convective Systems (MCSs), during the warm season. These MCSs may produce rainfalls, in a 1-2 day period, with amounts well above the monthly climatology. The ability to recognize the patterns and mechanisms that accompany these convective systems is crucial for forecasting their timing and location. Horizontal moisture flux convergence (MFC) is a useful tool in short-term prediction of convection since it contains information on the low-level forcing and the amount of moisture available. However, if there is no support in the upper levels then the likelihood of thunderstorm development is significantly diminished. Using the NARR (North American Regional Reanalysis) dataset, we compute the tropospheric MFC every 3 hours during a 36-year period (1979-2014) through the months of May to August. A 24-h running mean was applied to the 3-hourly tropospheric MFC, and the 99th percentile was selected. An additional criterion ensuring synoptic independence (five days before/after the largest event) was applied, yielding 72 cases. The low-level moisture transport (1000-700hPa) and upper level flow was analyzed for each case, facilitating the classification of cases. Classifications include 1) southwesterly, 2) high amplitude (HA), 3) low amplitude, 4) northwesterly: low amplitude, and 5) northwesterly: high amplitude and 6) other flow. The overall atmospheric circulation structures differ substantially among the categories, where some related more to an upstream trough and others to a downstream ridge. The HA category tended to have the highest precipitating cases due to the strong forcing for ascent found during a Q-vector analysis. Perhaps surprisingly, there were several cases that showed very little precipitation, these low precipitation cases were generally associated with a region of differential anticyclonic vorticity advection. The highest observed precipitating events in the Midwest were then compared to tropospheric MFC, where 6 out of the top 10 were associated with one of the 72 extreme tropospheric MFC cases. Finally, a case study was performed for one of these cases, that of 25 May 2011 to analyze the synoptic environment and forcing for ascent more carefully. We concluded that extreme vertically integrated, horizontal moisture flux convergence (VIMFC) is capable of capturing high precipitation cases, but not all extreme VIMFC cases have high precipitation; to ensure high precipitation, there needs to be upper-level divergence and convective available potential energy (CAPE)." --

This book was released on 2016-07-28 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these broad trends, scientists cautioned in the past that individual weather events couldn't be attributed to climate change. Now, with advances in understanding the climate science behind extreme events and the science of extreme event attribution, such blanket statements may not be accurate. The relatively young science of extreme event attribution seeks to tease out the influence of human-cause climate change from other factors, such as natural sources of variability like El Niño, as contributors to individual extreme events. Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.

Download or read book Thriving on Our Changing Planet A Decadal Strategy for Earth Observation from Space written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-06-18 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.

Download or read book Assessment of Intraseasonal to Interannual Climate Prediction and Predictability written by National Research Council and published by National Academies Press. This book was released on 2010-09-08 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: More accurate forecasts of climate conditions over time periods of weeks to a few years could help people plan agricultural activities, mitigate drought, and manage energy resources, amongst other activities; however, current forecast systems have limited ability on these time- scales. Models for such climate forecasts must take into account complex interactions among the ocean, atmosphere, and land surface. Such processes can be difficult to represent realistically. To improve the quality of forecasts, this book makes recommendations about the development of the tools used in forecasting and about specific research goals for improving understanding of sources of predictability. To improve the accessibility of these forecasts to decision-makers and researchers, this book also suggests best practices to improve how forecasts are made and disseminated.

This book was released on 2008 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Technical Paper addresses the issue of freshwater. Sealevel rise is dealt with only insofar as it can lead to impacts on freshwater in coastal areas and beyond. Climate, freshwater, biophysical and socio-economic systems are interconnected in complex ways. Hence, a change in any one of these can induce a change in any other. Freshwater-related issues are critical in determining key regional and sectoral vulnerabilities. Therefore, the relationship between climate change and freshwater resources is of primary concern to human society and also has implications for all living species. -- page vii.
