Identifying Perturbations That Tipped the Stratosphere Into a Sudden Warming During January 2013
We present a new methodology demonstrating that specific small‐magnitude regional perturbations can cause large systematic responses in subseasonal predictions.

Atmospheric transport and critical layer mixing in the troposphere and stratosphere [PDF]
This thesis aims to improve the understanding of transport and critical layer mixing in the troposphere and stratosphere. A dynamical approach is taken based on potential vorticity which has long been recognised as the essential field inducing the flow ...

Enhanced Polar Vortex Predictability Following Sudden Stratospheric Warming Events
Sudden stratospheric warming (SSW) events can form a window of forecast opportunity for polar vortex predictions on subseasonal‐to‐seasonal time scales.

Observations of Pole-to-Pole, Stratosphere-to-Ionosphere Connection
The behavior of the Earth’s middle atmosphere and ionosphere is governed by multiple processes resulting not only from downward energy transfer from the Sun and magnetosphere but also upward energy transfer from terrestrial weather.

Observed response of stratospheric and mesospheric composition to sudden stratospheric warmings [PDF]
Abstract In this study we investigate and quantify the statistical changes that occur in the stratosphere and mesosphere during 37 sudden stratospheric warming (SSW) events from 1989 to 2016. We consider changes in the in-situ ozonesonde observations of the stratosphere from four sites in the northern hemisphere (Ny-Alesund, Sodankyla, Lerwick, and ...

Gravity waves excited during a minor sudden stratospheric warming [PDF]
An exceptionally deep upper-air sounding launched from Kiruna airport (67.82° N, 20.33° E) on 30 January 2016 stimulated the current investigation of internal gravity waves excited during a minor sudden stratospheric warming (SSW) in the

Stratospheric circulation is a critical part of the Arctic ozone cycle. Sudden stratospheric warming events (SSWs) manifest the strongest alteration of stratospheric dynamics.

Influence of the sudden stratospheric warming on quasi-2-day waves [PDF]
The influence of the sudden stratospheric warming (SSW) on a quasi-2-day wave (QTDW) with westward zonal wave number 3 (W3) is investigated using the Thermosphere–Ionosphere–Mesosphere Electrodynamics General Circulation Model (TIME-GCM).

Stratospheric influence on North Atlantic marine cold air outbreaks following sudden stratospheric warming events [PDF]
Marine cold air outbreaks (MCAOs) in the northeastern North Atlantic occur due to the advection of extremely cold air over an ice-free ocean. MCAOs are associated with a range of severe weather phenomena, such as polar lows, strong surface winds and ...
