CEDAR email: EGU 2019 Session: ST3.7/AS4.54 Study of the middle and upper atmosphere irregularities to identify forcing mechanisms

[Naomi Maruyama - NOAA Affiliate]

Dear Colleagues,

We would like invite you to submit an abstract and participate in the
session, “*ST3.7/AS4.54 Study of the middle and upper atmosphere
irregularities to identify forcing mechanisms*” at the upcoming EGU General
Assembly in Vienna, 7-12 April 2019.

The abstract submission deadline is *10 January 2019, 13:00 CET.*

Session Description:

The study of the ionized and neutral atmosphere reveals to be an efficient
diagnostic tool to understand the interaction among the geospheres and the
impact of the solar wind on the Earth. Any variation from the expected
behaviour can be helpful to identify various forcing mechanisms originated
from below and above. The vertical coupling in the atmosphere involves the
influence of the upper atmospheric layers on climate and the response of
the ionosphere to the modification of neutral atmosphere chemistry and
dynamics. An exacerbation in the space weather conditions, in turn, can
cause changes in the neutral composition and in the electron density
structuring. In addition, natural hazards, such as tsunami, earthquakes,
thunderstorms can produce atmospheric acoustic gravity waves that result in
electron density perturbations in the ionosphere.
The broad availability of instruments on board satellites and hosted at
ground opens new opportunities of multi-disciplinary and multi-instruments
collaboration to advance the current understanding in the field.
This session welcomes observational, theoretical, and modeling
contributions on atmospheric irregularities to identify the coupling
mechanisms within the atmosphere, between the atmosphere and the
lithosphere, and between the atmosphere and the geospace.



We are looking forward to receiving your abstracts and participation.

Kind regards,

Conveners:

Lucilla Alfonsi, Elvira Astafyeva, Naomi Maruyama, Jøran I. Moen
