The Effect of Tropospheric Jet Latitude on Coupling between the Stratospheric Polar Vortex and the Troposphere Authors: Chaim I. Garfinkel, Darryn W. Waugh and Edwin P. Gerber Published online: 22nd March, 2013 Abstract: A dry general circulation model is used to investigate how coupling between the stratospheric polar vortex and the extratropical tropospheric circulation depends on the latitude of the tropospheric jet. The tropospheric response to an identical stratospheric vortex configuration is shown to be strongest for a jet centered near 40° an
Sensitivity of simulated convection‐driven stratosphere‐troposphere exchange in WRF‐Chem to the choice of physical and chemical parameterization Authors: Daniel B. Phoenix, Cameron R. Homeyer and Mary C. Barth Published By: "Earth and Space Science" Published online: 20th July, 2017 Abstract: Tropopause‐penetrating convection is capable of rapidly transporting air from the lower troposphere to the upper troposphere and lower stratosphere (UTLS), where it can have important impacts on chemistry, the radiative budget, and climate. Howev
Stratospheric Ozone: An Electronic Textbook Abstract: As discussed in Chapter 5, most ozone production occurs in the tropical stratosphere as the overhead sun breaks apart oxygen molecules (O2) into oxygen atoms (O), which quickly react with other O2 molecules to form ozone (O3). The problem with this simplified picture is that most ozone is found outside the tropics in the higher latitudes rather than in the tropics. That is, most of the ozone is found outside of its natural tropical stratospheric source region. This higher latitude ozone results from the slow atmospheric circul
Mechanisms Governing Interannual Variability of Stratosphere‐to‐Troposphere Ozone Transport Authors: John R. Albers, Judith Perlwitz, Amy H. Butler et al Published: 16th January, 2018 Abstract: Factors governing the strength and frequency of stratospheric ozone intrusions over the Pacific‐North American region are considered for their role in modulating tropospheric ozone on interannual timescales. The strength of the association between two major modes of climate variability—the El Niño–Southern Oscillation (ENSO) and the Northern Annular Mode
