An Explanation of the Poleward Mass Flux in the Stratosphere
This paper offers a new perspective on the explanation of the poleward mass flux in the stratosphere. This mass flux represents the upper leg of the so-called Brewer–Dobson circulation. This new perspective is based on the following hypothesis.

We quantify the changes in the intensity of Brewer‐Dobson Circulation (BDC) during sudden stratospheric warming (SSW) and its impact on the tropical stratospheric thermal structure and ozone distribution by composite analysis using observations and a ...

Modulation of Stratosphere‐to‐Troposphere Transport of Ozone by North Pacific Weather Patterns
Abstract Stratosphere‐to‐troposphere transport (STT) of ozone is a major natural source of tropospheric ozone and is tightly linked to both stratospheric and tropospheric circulations. However, the complex interactions of drivers make it challenging to understand the subseasonal variability of STT.

Impact of Sudden Stratospheric Warmings on the Stratosphere-to-Troposphere Transport of Ozone
not-yet-known not-yet-known not-yet-known unknown Sudden stratospheric warmings (SSWs) can significantly impact tropospheric weather systems. Previous studies suggest that SSWs may also influence stratosphere-to-troposphere transport (STT), but their spatial and temporal distribution and

The frequency of successive sudden stratospheric warming events has markedly increased since 2000s. Using multimodel experiments it is demonstrated that reduced sea ice leads to higher frequencies of successive warming events.

Influence of stratospheric sudden warming on the tropical intraseasonal convection
Madden–Julian oscillation (MJO), the dominant mode of intraseasonal variability in the tropical troposphere, has recently been shown to have a great impact on Northern Hemisphere (NH) extratropical stratosphere.

SuPerPoV: Score and Evolution of the Stratospheric Polar Vortex via Persistent Homology
Abstract Classifying the stratospheric polar vortex provides predictability for surface weather on extended‐range timescales. However, all definitions of these events proposed in over 60 years of study depend on empirically chosen parameters and yield different results when they change.

Stratosphere–Troposphere Coupling During Cold Air Outbreaks in the Eastern United States
Abstract Cold air outbreaks (CAOs) are extreme weather events characterized by the equatorward displacement of polar air. This study investigates CAOs occurring along the East Coast of the US and establishes that approximately 16% are driven by stratosphere‐troposphere coupling through wave dynamics.

All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Overview of Aerosols in the E3SM Version 3: New Model Features and Their Impacts
Abstract Accurate and comprehensive representation of aerosols in Earth system models (ESMs) is critical for modeling radiative forcing and seasonal‐to‐decadal variability. With increasing computing power, detailed physical and chemical processes representing aerosols and their interactions with other components of the Earth system can be treated more ...
