Migrating and nonmigrating diurnal tides in the middle and upper atmosphere excited by tropospheric latent heat release
Maura E. Hagan,Jeffrey M. Forbes +1 more
TL;DR: In this paper, the global scale wave model (GSWM) is used to investigate mesospheric and lower thermospheric migrating and non-migrating diurnal tidal components that propagate upward from the troposphere, where they are excited by latent heat release associated with deep tropical convection.

TL;DR: In this article, the seasonal and interannual variability of migrating and nonmigrating solar atmospheric tides at altitudes between 100 and 116 km were investigated using temperature measurements made with the SABER instrument on the TIMED spacecraft during 2002-2006.

Monthly tidal temperatures 20–120 km from TIMED/SABER
Xiaoli Zhang,Jeffrey M. Forbes,Maura E. Hagan,James M. Russell,Scott Palo,Christopher J. Mertens,Martin G. Mlynczak +6 more
TL;DR: In this paper, a new method of analyzing satellite data for tides has been developed to circumvent this difficulty, but at the expense of temporal resolution of the tidal fields, i.e., 120-day mean tidal structures are obtained.

Global Dynamics of the MLT
TL;DR: In this article, a review describes recent observa- tions and numerical modeling as they relate to understanding the dynamical processes that control the middle atmosphere and its variability, and results from the Whole Atmosphere Community Climate Model (WACCM), which is a comprehensive high-top general circulation model with interactive chemistry, are used to illustrate the dynamic processes.

Localization of the complex spectrum: the S transform
TL;DR: The S transform is shown to have some desirable characteristics that are absent in the continuous wavelet transform, and provides frequency-dependent resolution while maintaining a direct relationship with the Fourier spectrum.

Localisation of the complex spectrum : The S transform
TL;DR: The S transform as discussed by the authors is an extension to the ideas of the Gabor transform and the Wavelet transform, based on a moving and scalable localising Gaussian window and is shown here to have characteristics that are superior to either of the transforms.
