RISNonstationary Synchronization of Equatorial QBO with SAO in Observations and a Model
Publisher: American Meteorological Society
Abstract: It has often been suggested that the period of the quasi-biennial oscillation (QBO) has a tendency to synchronize with the semiannual oscillation (SAO). Apparently the synchronization is better the higher up the observation ...
Influence of Doubled CO2 on Ozone via Changes in the Brewer–Dobson Circulation
Publisher: American Meteorological Society
Abstract: In this short note, the effect of enhanced circulation due to doubling CO2 on ozone is investigated. The difference of Brewer?Dobson circulation (BDC) between the doubled CO2 and control run from an idealized atmospheric ...
Modulation of the Period of the Quasi-Biennial Oscillation by the Solar Cycle
Publisher: American Meteorological Society
Abstract: The authors examine the mechanism of solar cycle modulation of the Quasi-Biennial Oscillation (QBO) period using the Two-and-a-Half-Dimensional Interactive Isentropic Research (THINAIR) model. Previous model results (using ...
Influence of Stratospheric Sudden Warming on AIRS Midtropospheric CO2
Publisher: American Meteorological Society
Abstract: idtropospheric CO2 retrievals from the Atmospheric Infrared Sounder (AIRS) were used to explore the influence of stratospheric sudden warming (SSW) on CO2 in the middle to upper troposphere. To choose the SSW events that ...
The Mechanical Energies of the Global Atmosphere in El Niño and La Niña Years
Publisher: American Meteorological Society
Abstract: wo meteorological reanalysis datasets are analyzed to determine the mechanical energies of the global atmosphere in the El Niño and La Niña years. The general consistency of the mean energy components between the two ...
Modulation of Midtropospheric CO2 by the South Atlantic Walker Circulation
Publisher: American Meteorological Society
Abstract: idtropospheric CO2 data from the Atmospheric Infrared Sounder (AIRS) are used in this study to explore the variability of CO2 over the South Atlantic Ocean. It was found that the area-averaged CO2 over the South Atlantic ...
Interannual Variability and Trends of Extratropical Ozone. Part I: Northern Hemisphere
Publisher: American Meteorological Society
Abstract: The authors apply principal component analysis (PCA) to the extratropical total column ozone from the combined merged ozone data product and the European Centre for Medium-Range Weather Forecasts assimilated ozone from ...
Interannual Variability and Trends of Extratropical Ozone. Part II: Southern Hemisphere
Publisher: American Meteorological Society
Abstract: A principal component analysis (PCA) is applied to the Southern Hemisphere (SH) total column ozone following the method established for analyzing the data in the Northern Hemisphere (NH) in a companion paper. The interannual ...
El Niño–Southern Oscillation in Tropical and Midlatitude Column Ozone
Publisher: American Meteorological Society
Abstract: he impacts of El Niño?Southern Oscillation (ENSO) on the tropical total column ozone, the tropical tropopause pressure, and the 3.5-yr ozone signal in the midlatitude total column ozone were examined using the Goddard Earth ...
A Comparative Study of Atmospheric Moisture Recycling Rate between Observations and Models
Publisher: American Meteorological Society
Abstract: AbstractPrecipitation and column water vapor data from 13 CMIP5 models and observational datasets are used to analyze atmospheric moisture recycling rate from 1988 to 2008. The comparisons between observations and model ...
