Rocket emissions thin the stratospheric ozone layer. To understand if significant ozone losses could occur as the launch industry grows, we examine two scenarios. Our 'ambitious' scenario (2040 launches/year) yields a -0.29% depletion in an...
Disentangling density and geometry in weather regime dimensions using stochastic twins [0.03%]
基于随机配对方法揭示天气型的几何与密度特性

Large-scale atmospheric variability can be summarized by recurring patterns called weather regimes. Their properties, including predictability, have been studied using the local dimension, a geometrical estimate of degrees of freedom from m...
Impact of water vapor on stratospheric temperature after the 2022 Hunga Tonga eruption: direct radiative cooling versus indirect warming by facilitating large particle formation [0.03%]
2022年洪加汤加火山喷发后水蒸气对平流层温度的影响：直接辐射冷却与通过促进大粒子形成而产生的间接变暖效应
Xi Chen,Jun Wang,Meng Zhou et al.
Xi Chen et al.
The unprecedented water vapor amount (WV, 150-160 Tg) injected by the 2022 eruption of Hunga Tonga-Hunga Ha'apai not only directly cooled the stratosphere, but also facilitated the formation and growth of sulfate particles, indirectly heati...
Disentangling anthropogenic and dynamic contributions to recent ocean warming [0.03%]
解开近期海洋变暖中的人为因素与动力学因素的贡献关系

As the ocean absorbs over 90% of excess radiative heat, recent ocean warming is shaped by a combination of anthropogenic surface heat gain and dynamical processes redistributing heat. To distinguish these contributions, we introduce a novel...
Oxygen-rich anionic metal silicate clusters as nucleation seeds for noctilucent clouds [0.03%]

Silicate-based meteoric smoke particles (MSPs) resulting from extraterrestrial dust impacting on the upper atmosphere are likely involved in seeding the formation of mesospheric ice-based noctilucent clouds (NLCs). However, the detailed phy...

Evidence has emerged that the North Atlantic Oscillation (NAO) may be predictable on decadal timescales, which may greatly benefit society given the significant climate impacts that accompany the NAO. However, the mechanisms behind the appa...
Global and regional drivers for exceptional climate extremes in 2023-2024: beyond the new normal [0.03%]
2023至2024年特殊气候极端事件的全球和区域驱动因子：超越新常态

Shoshiro Minobe et al.
Climate records have been broken with alarming regularity in recent years, but the events of 2023-2024 were exceptional even when accounting for recent climatic trends. Here we quantify these events across multiple variables and show how ex...

The effect of future climate change on the boreal winter response to strong El Niño is investigated using pacemaker simulations with the EC-Earth3-CC model constrained towards observed tropical Pacific sea surface temperature anomalies. Un...
Isotopic source signatures of stratospheric CO inferred from in situ vertical profiles [0.03%]
平流层一氧化碳同位素源信号的原位垂直分布特征分析

Joram J D Hooghiem et al.
The stratospheric CO budget is determined by CH4 oxidation, OH-driven loss and atmospheric transport. These processes can be constrained using CO mole fractions and isotopic compositions, with the latter being largely unexplored. We present...
Are AI weather models learning atmospheric physics? A sensitivity analysis of cyclone Xynthia [0.03%]
人工智能天气模型在学习大气物理吗？关于旋风Xynthia的敏感性分析
Jorge Baño-Medina,Agniv Sengupta,James D Doyle et al.
Jorge Baño-Medina et al.
Artificial Intelligence (AI) weather models are explored for initial condition sensitivity studies to analyze the physicality of the relationships learned. Gradients (or sensitivities) of the target metric of interest are computed with resp...
