Identifying Perturbations That Tipped the Stratosphere Into a Sudden Warming During January 2013
Geophysical Research Letters, 2023 We present a new methodology demonstrating that specific small‐magnitude regional perturbations can cause large systematic responses in subseasonal predictions.

Enhanced Polar Vortex Predictability Following Sudden Stratospheric Warming Events
Geophysical Research Letters, 2023 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
Frontiers in Astronomy and Space Sciences, 2022 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.

Gravity waves excited during a minor sudden stratospheric warming [PDF]
Atmospheric Chemistry and Physics, 2018 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 wave driving events as an alternative to sudden stratospheric warmings [PDF]
Weather and Climate Dynamics, 2022 Natural variations in the strength of the northern stratospheric polar vortex, so-called polar vortex events, help to improve subseasonal-to-seasonal (S2S) predictions of winter climate.

Influence of the sudden stratospheric warming on quasi-2-day waves [PDF]
Atmospheric Chemistry and Physics, 2016 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]
Weather and Climate Dynamics, 2020 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 ...

Observed response of stratospheric and mesospheric composition to sudden stratospheric warmings [PDF]
Journal of Atmospheric and Solar-Terrestrial Physics, 2019 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 ...

Stratospheric wave driving events as an alternative to sudden stratospheric sudden warmings [PDF]
, 2022 Abstract. Natural variations in the strength of the northern stratospheric polar vortex, so-called polar vortex events, help to improve sub-seasonal to seasonal (S2S) predictions of winter climate. Past research on polar vortex events has been largely focused on stratospheric sudden warming events (SSWs), a class of relatively strong weakenings of the ...
