We conducted an analysis of the process of GW breaking from an energy perspective using the output from a high-resolution compressible atmospheric model. The investigation focused on the energy conversion and transfer that occur during the GW breaking. The total change in kinetic energy and the amount of energy converted to internal energy and potential energy within a selected region were calculated. Prior to GW breaking, part of the potential energy is converted into kinetic energy, most of which is transported out of the chosen region. After the GW breaks and turbulence develops, part of the potential energy is converted …
The United States, China, And Climate Change: An Analysis Of The Us-China Climate Pact And Its Implications For International Climate Negotiations, Joesph Fiorile
Honors Theses
Climate change increasingly is becoming a major issue for the international community. It is contributing to rising global temperatures, rising sea levels, drought, natural disaster intensification, and ecological damage, amongst other things. A scientific consensus has emerged over recent years that implicates greenhouse gases, chief amongst them carbon dioxide, for causing global warming. Climate scientists overwhelmingly agree that the greenhouse gas effect has been caused in large part by the spike of human emissions since the dawn of the Industrial Revolution. To reverse the problem, the density of greenhouse gases in Earth’s atmosphere, especially carbon dioxide, has to be reduced. …

Trends Of Wind And Wind Power Over The Coterminous United States, Eric M. Holt
Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research
The trends of wind and wind power at a typical wind turbine hub height (80 m) are analyzed using the North American Regional Reanalysis (NARR) dataset for 1979-2009. Based upon the wind speeds at NARR’s vertical layers right above and below the 80 m level, the wind speeds at 80 m are estimated using two methods assuming the wind profile respectively as linear and power-law distribution with respect to the altitude in the lower boundary layer. Furthermore, we calculate the following variables at 80 m that are needed for the estimation and interpretation of wind power: the air density, zonal …
