Role of tropical lower stratosphere winds in quasi-biennial oscillation disruptions
In 2016, the westerly quasi-biennial oscillation (WQBO) in the equatorial stratosphere was unprecedentedly disrupted by westward forcing near 40 hPa; this was followed by...- publication PDF

Observed changes in interannual precipitation variability in the United States
Characterizing changes in precipitation patterns over time is critical for hydrologically dependent fields like water resource management and agriculture. Here, we explore...- publication PDF

Aircraft testing of the new Blunt-body Aerosol Sampler (BASE)
There is limited understanding of the role of aerosols in the formation and modification of clouds, partly due to inadequate data on such systems. Aircraft-based aerosol...- publication PDF
