Sudden stratospheric warmings (SSWs) are impressive fluid dynamical events in which
large and rapid temperature increases in the winter polar stratosphere (∼ 10–50 km) are …

The transition between the middle atmosphere and the thermosphere is known as the MLT
region (for mesosphere and lower thermosphere). This area has some characteristics that …

Major, sudden midwinter stratospheric warmings (SSWs) are large and rapid temperature
increases in the winter polar stratosphere are associated with a complete reversal of the …

Chemical ozone destruction occurs over both polar regions in local winter–spring. In the
Antarctic, essentially complete removal of lower-stratospheric ozone currently results in an …

The coupling of the ionosphere to processes from below remains an elusive and difficult
problem, as rapidly changing external drivers from above mask variations related to lower …

This paper compares results from a whole atmosphere‐ionosphere coupled model, GAIA,
with the COSMIC and TIMED/SABER observations during the 2008/2009 northern winter …

We investigate the ionospheric response to several stratospheric sudden warming events
which occurred in Northern Hemisphere winters of 2008 and 2009 during solar minimum …

There are several external sources of ionospheric forcing, including these are solar wind-
magnetospheric processes and lower atmospheric winds and waves. In this work we review …

Large-scale, intra-seasonal to inter-annual variability of the stratosphere is reviewed. Much
of the variability is dynamical and induced by waves emanating from the troposphere. It is …
