The Northern Hemispheric winter is disturbed by large scale variability mainly caused by
Planetary Waves (PWs), which interact with the mean flow and thus result in Sudden …

During winter the wind field in the mesosphere/lower thermosphere (MLT) at middle and
polar latitudes is characterized by a strong variability due to enhanced planetary wave …

The factors affecting the downward propagation of stratospheric sudden warming (SSW)
events to the troposphere are studied through composite analysis of 45‐year reanalysis data …

Stratospheric Sudden Warming (SSW) events are typically, but not always, accompanied by
negative Northern Annular Mode anomalies in the troposphere. However, large …

It is well known that stratospheric sudden warmings (SSWs) are a result of the interaction
between planetary waves (PWs) and the stratospheric polar vortex. SSWs occur when …

This study presents comparison of low-latitude dynamical responses to boreal 2008/09 and
austral 2002 winter Major Stratospheric Warming (MSW) events, as both events are of vortex …

In the present communication, characteristics of mean winds and planetary waves in the
mesosphere lower thermosphere (MLT) region during sudden stratospheric warming (SSW) …

Sudden stratospheric warming (SSW) events often lead to a cold surface air temperature
anomaly over the extratropical regions. In this study, we propose, through observational …

The previously reported observation of anomalous eastward gravity wave forcing at
mesopause heights around the onset of the January 2013 major sudden stratospheric …

This study investigates the effect of stratospheric sudden warmings (SSWs) on planetary
wave (PW) activity in the mesosphere–lower thermosphere (MLT). PW activity near 95 km is …
