This captivating book delves into the intricate origins and dynamic properties of atmospheric inertia-gravity waves in the Antarctic mesosphere. Gravity waves, characterized by their relatively small scale and buoyancy-driven restoring force, possess the remarkable ability to transport momentum upward from the troposphere to the middle atmosphere. While previous studies have explored the dynamical characteristics of mesospheric gravity waves, their full examination through numerical simulations has been limited due to the considerable computational power required. However, recent advancements in computational capabilities have opened the door to conducting numerical simulations using atmospheric general circulation models, which span from the troposphere to the mesosphere with a sufficiently fine horizontal resolution to capture the intricate details of small-scale gravity waves.

The book begins by presenting a comprehensive simulation of mesospheric gravity waves utilizing a high-resolution non-hydrostatic atmospheric model featuring a high model top. The accuracy of the numerical results is substantiated by the pioneering Mesosphere-Stratosphere-Troposphere/Incoherent Scattering (MST/IS) radar observation conducted in the Antarctic. Furthermore, it offers a detailed account of the genesis and propagation mechanisms of mesospheric gravity waves, drawing upon the insights gained from the high-resolution numerical model. By employing both fundamental and cutting-edge theories of fluid dynamics, the book adeptly elucidates the intricate behaviors of mesospheric gravity waves, shedding light on their role in shaping the atmospheric dynamics of the Antarctic region.

This captivating exploration of atmospheric inertia-gravity waves in the Antarctic mesosphere not only broadens our understanding of atmospheric phenomena but also underscores the significant advancements in computational technology that have enabled us to delve deeper into the complex dynamics of the Earth's atmosphere.
