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.

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 ...

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

Analyzing ozone variations and uncertainties at high latitudes during sudden stratospheric warming events using MERRA-2

, 2022
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]

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 ...

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.

The stratospheric polar vortex and sudden stratospheric warmings [PDF]

Weather, 2020
The polar vortex is the dominant feature of the wintertime stratosphere. Sometimes, it is unusually strong, while at others it is very weak or destroyed in an event known as a sudden stratospheric warming (SSW). Both can play an important role in driving the type and predictability of the weather we experience at the surface.
