Planetary wave induced wind and airglow oscillations in the middle latitude MLT region

Journal of Atmospheric and Solar-Terrestrial Physics, 2013
Abstract Upper mesosphere airglow emissions and temperature observed at Rikubetsu (43.5°N,143.8°E) and mesospheric winds observed at Wakkanai (45.4°N,141.8°E), Japan, from January to December 2005 were used to analyze periodic oscillations of 2–16 days.

An enhancement of the lunar tide in the MLT region observed in the Brazilian sector during 2006 SSW

Journal of Atmospheric and Solar-Terrestrial Physics, 2012
Abstract Meteor radar observations at Sao Joao do Cariri (7.4°S, 36.5°W), Cachoeira Paulista (23°S, 45°W) and Santa Maria (29.7°S, 53.7°W) have permitted estimates to be made of winds and temperature in the mesosphere and lower thermosphere (MLT). Using horizontal winds the lunar semidiurnal tide was determined from January 2005 to December 2008 for ...

Influence of solar activity on the chemistry of the MLT-region modelled with ICON-ART

During times of high solar activity an increased amount of solar coronal mass ejections (CME) are observed and initiate geomagnetic storms. These solar wind particles are guided and accelerated by Earth's magnetic field and get redirected towards the polar region, where they precipitate into the atmosphere of Earth.

Observed responses of tides and gravity waves in the MLT region to the Madden-Julian Oscillation

This work analyzed the intraseasonal variability of non-migrating tides DE3 and gravity wave momentum fluxes (GWMF) in the mesosphere and lower thermosphere (MLT) region and discussed the possible connection with the tropospheric MJO. Based on the joint observations of the TIMED-TIDI satellite and the 120°E meridian meteor radar chain, we ...

Impact of Sudden Stratospheric Warmings on the Neutral Density, Temperature and Wind in the MLT region

In this study, the neutral density and horizontal wind observed by the four meteor radars, as well as the temperature measured by the Microwave Limb Sounder (MLS) onboard the Aura satellite are used to examine the response of neutral density, wind, and temperature in the MLT region to the stratospheric sudden warmings (SSWs) during 2005 to 2021 in the ...
