Meteor Radar for Investigation of the MLT Region: A Review

open access: yesAtmosphere
This is an introductory review of modern meteor radar and its application to the measurement of the dynamical parameters of the Mesosphere Lower Thermosphere (MLT) Region within the altitude range of around 70 to 110 km, which is where most meteors are ...

Rotational effects in the field of tidal wind of the mid-latitude MLT-region [PDF]

open access: yesAdvances in Space Research, 2003
Investigation of non-linear effects in the approach of quadratic coupling of tidal motions and planetary waves with taking into consideration their polarization properties was carried out. The investigation was based on the wind observations performed by meteor radar station of Kazan State University (Russia, Kazan, 56N, 49E) in the MLT-region (80 ...

Effects of the stratospheric sudden warming on the temperature in the MLT region [PDF]

open access: yesAdvances in polar upper atmosphere research, 2003
P(論文)We investigate effects of the stratospheric sudden warming on the temperature in the MLT (mesosphere and lower thermosphere) region by using a general circulation model up to 150km height.

Investigating the role of gravity waves in mesosphere and lower-thermosphere (MLT) inversions at low latitudes [PDF]

open access: yesAnnales Geophysicae
The mesosphere and lower-thermosphere (MLT) transitional region, encompassing a height range of 60–100 km, is a distinct and highly turbulent zone within Earth's atmosphere.

Periodic auroral events at the high‐latitude convection reversal in the 16 MLT region [PDF]

open access: yesGeophysical Research Letters, 1990
Combined optical and radar observations of two breakup‐like auroral events near the polar cap boundary, within 74–76° MLAT and 1210 – 1240 UT (roughly 1540 – 1610 MLT) on 9 Jan. 1989 are reported. A two‐component structure of the auroral phenomenon is indicated, with a local intensification of the pre‐existing arc as well as a separate, tailward moving

The spatial distribution of region 2 field-aligned currents relative to subauroral polarization stream [PDF]

open access: yesAnnales Geophysicae, 2014
To test the current-generation model of subauroral polarization stream (SAPS), we have investigated the relative positions of field-aligned currents (FACs) with respect to SAPS in a statistical way by using CHAMP (CHAllenging Minisatellite Payload ...

Impact of sudden stratospheric warmings on the neutral density, temperature and wind in the MLT region [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2023
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 ...

Intraseasonal oscillation (ISO) in the MLT zonal wind over Kolhapur (16.8° N) and Tirunelveli (8.7° N) [PDF]

open access: yesAnnales Geophysicae, 2012
Simultaneous observations of the mean zonal winds at 88 km obtained by the medium-frequency (MF) radars at Kolhapur (16.8° N, 74.2° E) and Tirunelveli (8.7° N, 77.8° E) have been used to study the intraseasonal oscillation (ISO) in the MLT region. The

Study of the Tidal Variations in the Ionosphere and the MLT Region over Mohe and Beijing During Six Intense Geomagnetic Storms from 2016 to 2021

open access: yesRemote Sensing
Geomagnetic storms can cause large variations in the ionosphere, but their impacts on the mesosphere and lower thermosphere (MLT) are not well understood. Based on the Total Electron Content (TEC) data and the meteor neutral winds data over Mohe (53.5°N,
