atmospheric as well as magnetospheric forcings. Various atmospheric waves, excited in the troposphere, can reach this region in their course of propagation, and control and modify the dynamics of the ambience. Large-scale middle atmospheric disturbances, e. g. sudden stratospheric warming, have a mighty impact on the overlying mesosphere-thermosphere system through dynamical coupling. The geomagnetic disturbances driven by strong solar activities can impact significantly through precipitation of energetic charge particles in the ionosphere causing heating and associated alteration in the circulation pattern therein. Owing to complexities of physical processes and lack of investigation, various observed features are not completely understood and require extensive multi-platform and multi-instrument observations as well as modeling studies. Clear understanding of this coupled region is essential to delineate a broader perspective of the Sun-Earth interactions. </span><span style="font-size:12pt;font-family:'times new roman' , serif"></span></p><p class="MsoNormal" style="margin:0px;line-height:normal;vertical-align:baseline"><span style="font-size:12pt;font-family:'arial' , sans-serif;border:none 1pt;padding:0in" lang="EN-GB">You can read more about the collection </span><a href="https://www.frontiersin.org/research-topics/53262/advances-in-mesosphere-and-thermosphere-dynamics#overview" rel="noopener nofollow noopener noreferrer nofollow noopener noreferrer" target="_blank"><span style="font-size:12pt;font-family:'arial' , sans-serif;color:blue;border:none 1pt;padding:0in" lang="EN-GB">here</span></a><span style="font-size:12pt;font-family:'arial' , sans-serif;border:none 1pt;padding:0in" lang="EN-GB">.</span><span style="font-size:12pt;font-family:'times new roman' , serif"></span></p><p class="MsoNormal" style="margin:0px;line-height:normal;vertical-align:baseline"><span style="font-size:12pt;font-family:'times new roman' , serif"> </span></p><p class="MsoNormal" style="margin:0px;line-height:normal;vertical-align:baseline"><span style="font-size:12pt;font-family:'times new roman' , serif"> </span></p><p class="MsoNormal" style="margin:0px;line-height:normal;vertical-align:baseline"><span style="font-size:12pt;font-family:'arial' , sans-serif;border:none 1pt;padding:0in" lang="EN-GB">Why publish on this Research Topic?</span><span style="font-size:12pt;font-family:'times new roman' , serif"></span></p><p class="MsoNormal" style="margin:0px;line-height:normal;vertical-align:baseline"><span style="font-size:12pt;font-family:'arial' , sans-serif;border:none 1pt;padding:0in" lang="EN-GB">Alongside a top group of authors, the accepted work will be published in Frontiers in Astronomy and Space Sciences, a leading journal in the field with a Journal Impact Factor of 4.055 and a CiteScore of 4.1.</span><span style="font-size:12pt;font-family:'times new roman' , serif"></span></p><p class="MsoNormal" style="margin:0px;line-height:normal;vertical-align:baseline"><span style="font-size:12pt;font-family:'times new roman' , serif"> </span></p><p class="MsoNormal" style="margin:0px;line-height:normal;vertical-align:baseline"><span style="font-size:12pt;font-family:'arial' , sans-serif;border:none 1pt;padding:0in" lang="EN-GB">Please click the </span><a href="https://www.frontiersin.org/research-topics/53262/advances-in-mesosphere-and-thermosphere-dynamics/participate-in-open-access-research-topic" rel="noopener nofollow noopener noreferrer nofollow noopener noreferrer" target="_blank"><span style="font-size:12pt;font-family:'arial' , sans-serif;color:blue;border:none 1pt;padding:0in" lang="EN-GB">link </span></a><span style="font-size:12pt;font-family:'arial' , sans-serif;border:none 1pt;padding:0in" lang="EN-GB">to register your interest in submitting an article.
