From Surface to Tropopause: On the Vertical Structure of the Tropical Cyclone Vortex

April 30, 2024

Alexander DesRosiers

The internal vortex structure of a tropical cyclone (TC) influences intensity change. Beneficial structural characteristics that allow TCs to capitalize on favorable environmental conditions are an important determinant as to whether a TC will undergo rapid intensification (RI) or not. Accurately forecasting RI is a significant challenge and past work identified characteristics of radial and…

AIR QUALITY IMPACTS FROM UNCONVENTIONAL OIL AND GAS DEVELOPMENT

January 10, 2024

I-Ting Ku

Unconventional oil and natural gas development (UOGD) has expanded rapidly across the United States raising concerns about associated air quality impacts. While significant effort has been made to quantify and limit methane emissions, relatively few observations have been made of emitted Volatile Organic Compounds (VOCs). Extensive air monitoring during development of several large, multi-well…
