The High Arctic in Extreme Winters: Vortex, Temperature, and MLS and ACE-FTS Trace Gas Evolution [PDF]
The first three Canadian Arctic Atmospheric Chemistry Experiment (ACE) Validation Campaigns at Eureka (80° N, 86° W) were during two extremes of Arctic winter variability: Stratospheric sudden warmings (SSWs) in 2004 and 2006 were among the strongest ...

We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

Vertical Moist Thermodynamic Structure and Spatial–Temporal Evolution of the MJO in AIRS Observations [PDF]
The atmospheric moisture and temperature profiles from the Atmospheric Infrared Sounder (AIRS)/Advanced Microwave Sounding Unit on the NASA Aqua mission, in combination with the precipitation from the Tropical Rainfall Measuring Mission (TRMM), are ...

The climatological‐error covariance matrix used in three‐dimensional variational data assimilation (3DVar) provides smooth and isotropic increments spread to long distances. In contrast, three‐dimensional ensemble variational data assimilation (3DEnVar) with a purely ensemble‐error covariance matrix provides inhomogeneous increments and contains the ...

Stratosphere troposphere coupling: the influence of volcanic eruptions [PDF]
Stratospheric sulfate aerosols produced by major volcanic eruptions modify the radiative and dynamical properties of the troposphere and stratosphere through their reflection of solar radiation and absorption of infrared radiation. At the Earth's surface,

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Stratosphere - troposphere coupling by planetary waves [PDF]
The stratosphere and troposphere exhibit strong coupling during the active seasons of the stratosphere (winter/spring in the Northern/Southern Hemispheres), which are characterized by bursts of planetary-scale Rossby waves and by large stratospheric wind

Observationally derived transport diagnostics for the lowermost stratosphere and their application to the GMI chemistry and transport model [PDF]
Transport from the surface to the lowermost stratosphere (LMS) can occur on timescales of a few months or less, making it possible for short-lived tropospheric pollutants to influence stratospheric composition and chemistry.

Diversity of Stratospheric Error Growth Across Subseasonal Prediction Systems
The stratosphere has previously been shown to be a significant source of subseasonal tropospheric predictability. The ability of ensemble prediction systems to appropriately exploit this depends on their ability to reproduce the statistical properties of
