Abstract: This paper presents analyses of nonmigrating diurnal tide signatures in High Resolution Doppler Imager mesospheric and lower-thermospheric winds and temperatures. A global comparison of both winds and temperature reveals ...

Abstract: Variability in the solar ultraviolet radiative flux is known to cause changes in the chemistry and dynamics of the middle and upper atmosphere. Specifically, the 27-day solar rotation signal in irradiance has been correlated ...

Abstract: A diagnostic technique has been developed to consistently derive all the dynamical and chemical tracer fields based on one or a few well-measured fields such as temperature and ozone distributions. The technique is based ...

Abstract: There are three distinct processes by which upward-propagating gravity waves influence the large-scale dynamics and energetics of the middle atmosphere: (i) nonlocalized transport of momentum through wave propagation in ...

Abstract: he authors present a new method to diagnose the middle-atmosphere climate sensitivity by extending the climate feedback?response analysis method (CFRAM) for the coupled atmosphere?surface system to the middle atmosphere. ...
