Stratosphere - troposphere interaction during stratospheric sudden warming events
The stratosphere and the troposphere exhibit a strong coupling during the winter months. However, the coupling mechanisms between the respective vertical layers are not fully understood. An idealized spectral core dynamical model is utilized in the present study in order to clarify the coupling …

Layer-layer interactions in atmospheric, cryospheric, and stellar dynamics
… phenomena. I focus on three different systems: stratosphere-troposphere coupling, ice-sediment mechanics, and turbulence in velocity-layered stellar interiors. Three distinct manifestations of stratosphere-troposphere coupling are studied in this dissertation. First, evidence suggests that ozone …

The Downward Influence of Ozone Depletion in the Arctic Lower Stratosphere
Severe ozone depletion in the polar lower stratosphere has been linked to significant changes in tropospheric circulation patterns in the both hemispheres. Observed Southern Hemisphere circulation changes are easily reproduced in climate models and may be achieved by either increasing ozone …

Eurasian Snow Cover and the Role of Linear Interference in Stratosphere-troposphere Interactions
… and a negative NAM response that couples to the troposphere. It is shown that unexplained aspects of the evolution of this response can be clarified by examining the time evolution of the phasing, and hence the linear interference, between the wave response and the background climatological wave. …

The influence of Arctic sea-ice loss on mid-latitude weather and climate: exploring sensitivities and mechanisms
Over the past few decades, Arctic sea-ice extent has declined, while there has been an apparent increase in severe winter weather across some mid-latitude regions. This has led to much research into whether these trends are dynamically linked. It has been suggested that the link may involve the …
