A global non-hydrostatic model study of a downward coupling through the tropical tropopause layer during a stratospheric sudden warming [PDF]

Atmospheric Chemistry and Physics, 2015
The dynamical coupling process between the stratosphere and troposphere in the tropical tropopause layer (TTL) during a~stratospheric sudden warming (SSW) in boreal winter was investigated using simulation data from a global non-hydrostatic model (NICAM)

The association between stratospheric weak polar vortex events and cold air outbreaks

, 2009
Previous studies have identified an association between near-surface temperature anomalies in the Northern Hemisphere and weak stratospheric polar westerlies.

Validation of the Harvard Lyman-α in situ water vapor instrument: Implications for the mechanisms that control stratospheric water vapor [PDF]

, 2009
Building on previously published details of the laboratory calibrations of the Harvard Lyman-α photofragment fluorescence hygrometer (HWV) on the NASA ER-2 and WB-57 aircraft, we describe here the validation process for HWV, which includes laboratory ...

Natural Cycles, Gases [PDF]

, 1992
The major gaseous components of the exhaust of stratospheric aircraft are expected to be the products of combustion (CO2 and H2O), odd nitrogen (NO, NO2 HNO3), and products indicating combustion inefficiencies (CO and total unburned hydrocarbons).

Weakening of the stratospheric polar vortex by Arctic sea-ice loss [PDF]

Successive cold winters of severely low temperatures in recent years have had critical social and economic impacts on the mid-latitude continents in the Northern Hemisphere.

Meridional Wind in the Upper Stratosphere: A Source of Winter NAO Predictability

Geophysical Research Letters
Improvement of subseasonal to seasonal North Atlantic winter forecasting requires better prediction of the North Atlantic Oscillation (NAO), the dominant mode of variability in the Northern Hemisphere. Despite recent research demonstrating the importance

Accessible Climate and Impact Model Output for Studying the Human and Environmental Impacts of Nuclear Conflict

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
When a nuclear weapon is detonated in a region with sufficient fuel loading, the resulting firestorm can lift soot into the stratosphere, where it disperses globally over a few weeks. The soot, or black carbon, blocks sunlight, decreasing temperature and precipitation and depleting ozone.

The tropospheric response to zonally asymmetric momentum torques: implications for the downward response to wave reflection and SSW events [PDF]

Weather and Climate Dynamics
The role of zonal structure in the stratospheric polar vortex for the surface response to weak vortex states and concurrently occurring wave reflection events is isolated using an intermediate-complexity moist general circulation model.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Attributing Upper‐Tropospheric Warm Biases in CMIP6 Models to Ice Cloud‐Radiation Interaction Deficiencies Over Tropical Oceans

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract We assess the impact of hydrometeor radiative effects on tropical and subtropical Pacific air temperature anomalies (TAA) using Coupled Model Intercomparison Project Phase 6 (CMIP6) model simulations and satellite data. CMIP6 models are grouped by their treatment of frozen hydrometeors: SON2 (explicit cloud and falling ice), SON1 (simplified),
