The NAO Troposphere–Stratosphere Connection Authors: Maarten H. P. Ambaum and Brian J. Hoskins Published online: 15th July, 2002 Abstract: Using monthly mean data, daily data, and theoretical arguments, relationships between surface pressure variations associated with the North Atlantic Oscillation (NAO), tropopause height, and the strength of the stratospheric vortex are established. An increase in the NAO index leads to a stronger stratospheric vortex, about 4 days later, as a result of increased equatorward refraction of upward-propagating Rossby
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.
