The vertical coupling of the stratosphere‐mesosphere system through quasi‐stationary and
traveling planetary waves during the major sudden stratospheric warming (SSW) in the …

An exceptionally strong sudden stratospheric warming (SSW) in the Southern Hemisphere
(SH) during September 2019 was observed. Because SSW in the SH is very rare …

The transportable ground based microwave radiometer MIAWARA-C monitored the upper
stratospheric and lower mesospheric (USLM) water vapor distribution over Sodankylä …

Using the real‐time predictions from 11 models, this study analyzes the prediction of the
downward propagation and surface impact of the 2018 and 2019 sudden stratospheric …

Tidal variability in the mesosphere and lower thermosphere (MLT) during September 2019
Southern hemisphere minor sudden stratospheric warming (SSW) is investigated utilizing …

Severe ozone loss and significant surface warming anomalies in the Siberian Arctic were
observed in spring 2020. Here, we show that the anomalous surface warming was likely …

We introduce a new method to detect and monitor sudden stratospheric warming (SSW)
events using Global Navigation Satellite System (GNSS) radio occultation (RO) data at high …

A stratospheric sudden warming episode was self‐consistently generated in the coupled
National Center for Atmospheric Research Thermosphere, Ionosphere, Mesosphere, and …

We use two ground based Fabry–Perot interferometers (FPI) at Boulder (40° N, 105° W),
Resolute (75° N, 95° W), and a meteor radar at Bear Island (75° N, 19° E) to examine the …

Based on the data at~ 40° N at different longitudes during different stratospheric sudden
warming (SSW) events, the responses of zonal winds in the stratosphere, mesosphere and …
