The Relationship between the Gradient of Satellite-Derived Radiance and Upper Tropospheric/Lower Stratospheric Winds
Publisher: American Meteorological Society
Abstract: It is shown that the gradient of satellite-derived radiance is proportional to a certain vertical integral of the geostrophic wind. The radiance gradient is shown to be useful in locating the upper tropospheric jet maxima ...
Thermodynamic Balance of Three-Dimensional Stratospheric Winds Derived from a Data Assimilation Procedure
Publisher: American Meteorological Society
Abstract: The NASA/Goddard three-dimensional chemistry and transport model is driven by winds from a stratospheric data assimilation system. Synoptic- and planetary-scale patterns, apparent in satellite observations of trace ...
Lamination Frequencies as a Diagnostic for Horizontal Mixing in a 3D Transport Model
Publisher: American Meteorological Society
Abstract: Ozone simulations are performed in an attempt to simulate laminar events with the frequency observed in balloon ozone sondes. The winds are taken from the Goddard Earth Observing System Data Assimilation System (GEOS DAS); ...
Trends in Stratospheric Ozone: Lessons Learned from a 3D Chemical Transport Model
Publisher: American Meteorological Society
Abstract: Stratospheric ozone is affected by external factors such as chlorofluorcarbons (CFCs), volcanoes, and the 11-yr solar cycle variation of ultraviolet radiation. Dynamical variability due to the quasi-biennial oscillation ...
Relative Contribution of Greenhouse Gases and Ozone-Depleting Substances to Temperature Trends in the Stratosphere: A Chemistry–Climate Model Study
Publisher: American Meteorological Society
Abstract: The temperature of the stratosphere has decreased over the past several decades. Two causes contribute to that decrease: well-mixed greenhouse gases (GHGs) and ozone-depleting substances (ODSs). This paper addresses the ...
Application of a Monotonic Upstream-biased Transport Scheme to Three-Dimensional Constituent Transport Calculations
Publisher: American Meteorological Society
Abstract: The application of van Leer's scheme, a monotonic, upstream-biased differencing scheme, to three-dimensional constituent transport calculations is shown. The major disadvantage of the scheme is shown to be a self-limiting ...
Wintertime Nitric Acid Chemistry: Implications from Three-Dimensional Model Calculations
Publisher: American Meteorological Society
Abstract: A three-dimensional simulation of the evolution of HNO3 has been run for the winter of 1979. Winds and temperatures are taken from a stratospheric data assimilation analysis, and the chemistry is based on Limb Infrared ...
