Comparative study between ground-based observations and NAVGEM-HA reanalysis data in the MLT region [PDF]
, 2019 . Atmospheric waves are a key driving mechanism for the circulation in the Earth's atmosphere. Such waves covervarious spatial and temporal scales, e.g., planetary waves with periods of several days, atmospheric tides with periods of aninteger fraction ...

Analyzing the MLT region with mass spectrometers
The mesosphere and lower thermosphere (MLT) region is a key transition zone between Earth’s lower and upper atmospheres, where energetic processes, wave dynamics, and chemical reactions converge. Understanding the temperature and chemical composition in this region is crucial for interpreting processes at higher altitudes. Despite the MLT&

Suppressed migrating diurnal tides in the mesosphere and lower thermosphere region during El Niño in northern winter and its possible mechanism [PDF]
Atmospheric Chemistry and Physics, 2022 As observed by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER), the migrating diurnal tide (DW1) in the upper mesosphere and lower thermosphere (MLT) region decreased by ∼ 10 % during El Niño in the Northern Hemisphere (NH ...

Lagrangian transport experiments in the MLT region [PDF]
Earth, Planets and Space, 2014 In order to evaluate material transports in the upper mesosphere and lower thermosphere (MLT) region, Lagrangian transport experiments are performed using wind fields simulated by the Kyushu University middle atmosphere general circulation model (Miyahara and Miyoshi, 1997; Miyahara et al., 1993). The Lagrangian mean meridional circulation is different

Source regions for Antarctic MLT non‐migrating semidiurnal tides [PDF]
Geophysical Research Letters, 2009 Source regions for the westward propagating zonal wavenumber one and three components of the semidiurnal tide observed in the summer mesosphere and lower thermosphere over Antarctica are identified by correlating local tidal variations with global planetary wave one activity in the stratosphere and lower mesosphere.

The ultra-fast Kelvin waves in the equatorial ionosphere: observations and modeling [PDF]
Annales Geophysicae, 2013 The main purpose of this study is to investigate the vertical coupling between the mesosphere and lower thermosphere (MLT) region and the ionosphere through ultra-fast Kelvin (UFK) waves in the equatorial atmosphere.
