Item Open Access The atmospheric circulation response to climate change-like thermal forcings in a simple general circulation model(Colorado State University. Libraries, 2009) Butler, Amy Hawes, author; Thompson, David W. J., advisorTemperature changes due to increased greenhouse gases and depleted stratospheric ozone are associated with robust changes in the large-scale atmospheric circulation. In this thesis we explore how these anthropogenically-driven temperature changes affect the atmospheric circulation. Our approach is to force a simple dry dynamical general circulation model (GCM) with idealized thermal forcings that resemble three key effects of greenhouse gas increases and stratospheric ozone depletion: warming at the polar surface, warming of the tropical upper troposphere, and cooling of the polar stratosphere.
