RISEffect of Short-Term Solar Ultraviolet Flux Variability in a Coupled Model of Photochemistry and Dynamics
Publisher: American Meteorological Society
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 ...
Diagnosis of Dynamics and Energy Balance in the Mesosphere and Lower Thermosphere
Publisher: American Meteorological Society
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 ...
Diagnostic Analysis of Tidal Winds and the Eliassen–Palm Flux Divergence in the Mesosphere and Lower Thermosphere from TIMED/SABER Temperatures
Publisher: American Meteorological Society
Abstract: For migrating tides or fast-moving planetary waves, polarization relations derived from the linear wave equations are required to accurately derive the wind components from the temperature field. A common problem in ...

A Spectral Parameterization of Drag, Eddy Diffusion, and Wave Heating for a Three-Dimensional Flow Induced by Breaking Gravity Waves
Publisher: American Meteorological Society
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 ...
Diagnosis of Middle-Atmosphere Climate Sensitivity by the Climate Feedback–Response Analysis Method
Publisher: American Meteorological Society
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. ...
