Darryn Waugh

About

Darryn Waugh's main research interests are oriented toward understanding dynamics and transport in the atmosphere and oceans. His research in the atmosphere focuses on stratospheric and upper tropospheric dynamics and transport. Improved understanding of, and ability to model, fluid motions in these regions is important for understanding the distribution of trace constituents, such as ozone, and for assessing the impact of human activities on the atmospheric environment. In recent years, he has also become interested in the transport in oceans and lakes, and the uptake of anthropogenic carbon. He holds a PhD from Cambridge University in Earth & Planetary Sciences.

• Ventilation of the Southern Ocean Pycnocline

  Annual Review of Marine Science · 2021 · 81 citations

  Ocean ventilation is the transfer of tracers and young water from the surface down into the ocean interior. The tracers that can be transported to depth include anthropogenic heat and carbon, both of which are critical to understanding future climate trajectories. Ventilation occurs in both high- and midlatitude regions, but it is the southern midlatitudes that are responsible for the largest fraction of anthropogenic heat and carbon uptake; such Southern Ocean ventilation is the focus of this r…

• How Frequent Are Antarctic Sudden Stratospheric Warmings in Present and Future Climate?

  Geophysical Research Letters · 2021 · 59 citations

  Senior authorCorresponding

  Abstract Southern Hemisphere (SH) stratospheric sudden warmings (SSWs) result in smaller Antarctic ozone holes and are linked to extreme midlatitude weather on subseasonal to seasonal timescales. Therefore, it is of interest how often such events occur and whether we should expect more events in the future. Here, we use a pair of novel multimillennial simulations with a stratosphere‐resolving coupled ocean‐atmosphere climate model to show that the frequency of SSWs, such as observed 2002 and 201…

• Interannual SAM Modulation of Antarctic Sea Ice Extent Does Not Account for Its Long‐Term Trends, Pointing to a Limited Role for Ozone Depletion

  Geophysical Research Letters · 2021 · 39 citations

  Senior authorCorresponding

  Abstract The expansion of Antarctic sea ice since 1979 in the presence of increasing greenhouse gases remains one of the most puzzling features of current climate change. Some studies have proposed that the formation of the ozone hole, via the Southern Annular Mode, might explain that expansion, and a recent paper highlighted a robust causal link between summertime Southern Annular Mode (SAM) anomalies and sea ice anomalies in the subsequent autumn. Here we show that many models are able to capt…

• Shifting Islands: How weather conditions and urban form shape the spatiotemporal character of Baltimore's urban heat island

  Urban Climate · 2024-07-01 · 7 citations

  articleOpen access

  The combined effects of climate change and urban expansion are elevating urban temperatures, amplifying health risks, and increasing summertime energy demand. Effective heat reduction and adaptation strategies rely on a thorough understanding of urban heat island (UHI) dynamics, which vary within cities and over time due to local urban form and meteorological conditions. While existing studies have examined the spatiotemporal structure of UHIs, they have not examined the space-time variability o…
