The transition between the middle atmosphere and the thermosphere is known as the MLT
region (for mesosphere and lower thermosphere). This area has some characteristics that …

There are several external sources of ionospheric forcing, including these are solar wind-
magnetospheric processes and lower atmospheric winds and waves. In this work we review …

Sudden stratospheric warming (SSW) is a large‐scale meteorological process in the winter
hemisphere lasting several days or weeks. The Incoherent Scatter World Day campaign …

Microwave Limb Sounder and Sounding of the Atmosphere with Broadband Emission
Radiometry data provide the first opportunity to characterize the four‐dimensional …

At the turn of the century RG Roble advanced an ambitious program of developing an
atmospheric general circulation model (GCM) extending from the surface to the exosphere …

Based on a climate‐chemistry model (constrained by reanalyses below~ 50 km), the zonal‐
mean composite response of the mesosphere and lower thermosphere (MLT) to major …

This study analyzes a simulation of the Arctic winter 2016–2017 with focus on multi‐step
vertical coupling (MSVC) by primary, secondary, and higher‐order gravity waves (GWs). We …

Continuous MF and meteor radar observations allow detailed studies of winds in the
mesosphere and lower thermosphere (MLT) as well as temperatures around the …

We have studied the mesospheric response to two recent stratospheric warmings by
performing short‐term forecasts at medium (1.5°) and high (0.5°) spatial resolution under …

A Whole Atmosphere Model (WAM) has been used to explore the possible physical
connection between a sudden stratospheric warming (SSW) and the dynamics and …
