Effects of Latitude-Dependent Gravity Wave Source Variations on the Middle and Upper Atmosphere
Frontiers in Astronomy and Space Sciences, 2021 Atmospheric gravity waves (GWs) are generated in the lower atmosphere by various weather phenomena. They propagate upward, carry energy and momentum to higher altitudes, and appreciably influence the general circulation upon depositing them in the middle

Neutral winds from mesosphere to thermosphere—past, present, and future outlook
Frontiers in Astronomy and Space Sciences, 2023 The Earth’s upper atmosphere (85–550 km) is the nearest region of geospace and is highly dynamic in nature. Neutral winds impact a large portion of the dynamics in this region.

The upper-atmosphere extension of the ICON general circulation model (version: ua-icon-1.0) [PDF]
Geoscientific Model Development, 2019 How the upper-atmosphere branch of the circulation contributes to and interacts with the circulation of the middle and lower atmosphere is a research area with many open questions.

Spatial and temporal correlations of thermospheric zonal winds from GOCE satellite observations
Frontiers in Astronomy and Space Sciences, 2023 Winds in the thermosphere play an important role in the transport of momentum and energy in the upper atmosphere and affect the composition, dynamics and morphology of the ionospheric plasma.

Longitudinal variability of thermospheric zonal winds near dawn and dusk
Frontiers in Astronomy and Space Sciences, 2023 Understanding the morphology and dynamics of the thermosphere is key to understanding the Earth’s upper atmosphere as a whole. Thermospheric winds play an important role in this process by transporting momentum and energy and affecting the composition ...

Origins of mesoscale mixed-layer depth variability in the Southern Ocean [PDF]
Ocean Science, 2023 Mixed-layer depth (MLD) exhibits significant variability, which is important for atmosphere–ocean exchanges of heat and atmospheric gases. The origins of the mesoscale MLD variability in the Southern Ocean are studied here in an idealised regional ocean ...
