The Contributions of Several Absorption Bands to Stratospheric Radiative Dissipation Rates
Publisher: American Meteorological Society
Abstract: A narrowband (5 cm?1) radiation transfer scheme has been used to calculate scale-dependent radiative dissipation rates for finite-amplitude temperature disturbances. Eight bands of five atmospheric trace gases have been ...
The Major Stratospheric Sudden Warming of January 2013: Analyses and Forecasts in the GEOS-5 Data Assimilation System
Publisher: American Meteorological Society
Abstract: he major stratospheric sudden warming (SSW) of 6 January 2013 is examined using output from the NASA Global Modeling and Assimilation Office (GMAO) Goddard Earth Observing System version 5 (GEOS-5) near-real-time data ...
The Descent Rates of the Shear Zones of the Equatorial QBO
Publisher: American Meteorological Society
Abstract: The influence of vertical advection on the descent rate of the zero-wind line in both phases of the equatorial quasi-biennial oscillation (QBO) is investigated with the help of the ?THIN AIR? stratosphere two-and-a-half- ...
An EOF Analysis of the Vertical-Time Delay Structure of the Quasi-Biennial Oscillation
Publisher: American Meteorological Society
Abstract: Empirical orthogonal function analyses of the time-height series of monthly mean zonal wind in the stratosphere have been performed. Conventional EOF analysis on the time series reveals that the quasi-biennial oscillation ...
Phase–Space Characteristics of the Tropical Stratospheric Quasi-Biennial Oscillation
Publisher: American Meteorological Society
Abstract: Extended empirical orthogonal functions (EOFs) are used to define a phase space for the analysis of tropical stratospheric wind data, extending our previous study of the quasi-biennial oscillation (QBO) in several manners. ...
The Stratopause Semiannual Oscillation in the Berlin Troposphere–Stratosphere–Mesosphere GCM
Publisher: American Meteorological Society
Abstract: The tropical stratopause semiannual oscillation (SAO) in the Berlin troposphere?stratosphere?mesosphere general circulation model (TSM GCM) is investigated. The model is able to produce a semiannual oscillation that is ...
The 2015/16 El Niño Event in Context of the MERRA-2 Reanalysis: A Comparison of the Tropical Pacific with 1982/83 and 1997/98
Publisher: American Meteorological Society
Abstract: AbstractThe 2015/16 El Niño is analyzed using atmospheric and oceanic analysis produced using the Goddard Earth Observing System (GEOS) data assimilation systems. As well as describing the structure of the event, a theme ...
Chemical Source Inversion Using Assimilated Constituent Observations in an Idealized Two-Dimensional System
Publisher: American Meteorological Society
Abstract: A source inversion technique for chemical constituents is presented that uses assimilated constituent observations rather than directly using the observations. The method is tested with a simple model problem, which is a ...
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 ...
Evaluation of the Ozone Fields in NASA’s MERRA-2 Reanalysis
Publisher: American Meteorological Society
Abstract: AbstractThe assimilated ozone product from the Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), produced at NASA?s Global Modeling and Assimilation Office (GMAO) spanning the time period ...
