DOI: 10.1007/s00024-020-02569-y
Abstract: A numerical model of the propagation of acoustic-gravity waves excited by pressure fluctuations on the Earth’s surface is developed. Propagation of acoustic-gravity waves generated by instabilities of tropospheric fronts into the upper atmosphere is simulated.… read more here.

DOI: 10.1016/j.jastp.2019.04.011
Abstract: Abstract Anthropogenic polluting substances, mainly CO2, affect the lower atmosphere where they excite the well-known greenhouse warming. However, they also affect the upper atmosphere (mesosphere, thermosphere and embedded ionosphere), where they cause long-term trends stronger… read more here.
