How Moist and Dry Intrusions Control the Local Hydrologic Cycle in Present and Future Climates
Published in Journal of Climate, 2021
Models disagree on how much the hydrologic cycle could intensify under climate change. These changes are expected to scale with the Clausius–Clapeyron relation but may locally diverge due in part to the uncertain response of the general circulation, causing the hydrologic cycle to inherit this uncertainty. To identify how the circulation contributes, we link circulation changes to changes in the higher moments of the hydrologic cycle using the novel dynamical framework of the local hydrologic cycle, the portion of the…

Diabatic Eddy Forcing Increases Persistence and Opposes Propagation of the Southern Annular Mode in MERRA2
Published in Journal of Atmospheric Science, 2024
As a dominant mode of jet variability on sub-seasonal timescales, the Southern Annular Mode (SAM) provides a window into how the atmosphere can produce internal oscillations on longer-than-synoptic timescales. While SAM’s existence can be explained by dry, purely barotropic theories, the timescale for its persistence and propagation is set by a lagged interaction between barotropic and baroclinic mechanisms, making the exact physical mechanisms challenging to identify and to simulate, even in latest generation models. By partitioning the eddy momentum flux…

The Intraseasonal North Atlantic Oscillation as a Quasi-Semiannual Propagating Disturbance
Published:
The North Atlantic Oscillation (NAO) is a well-studied mode of regional climate variability over the Northern Atlantic ocean typically associated with fluctuations in sea-level pressure, storm tracks, and the North Atlantic jet. These fluctuations are classically understood to be a kind of see-sawing between one climatic phase, corresponding to a more poleward North Atlantic jet, and the other, a more equatorward North Atlantic jet, making the NAO a regionalized annular mode. However, recent work has shown that annular modes are…
