High-resolution aerosol liquid water content in the contiguous United States using machine learning [0.03%]
基于机器学习的美国本土高分辨率气溶胶液态水含量研究
Bingqing Zhang,Lifei Yin,Yuhan Yang et al.
Bingqing Zhang et al.
Aerosol liquid water content (ALWC) plays an important role in climate and public health by influencing aerosol formation, chemical composition, and toxicity. However, ALWC remains sparsely measured and poorly constrained across space and t...
Sunglint imprints of steady subcloud cells anchoring intermittent trade cumulus [0.03%]
稳定的下云细胞贸易积云的 sunglint痕迹imshow()

Ilan Koren et al.
How can seemingly random, shallow trade-wind clouds be predicted and their climate impact better evaluated? These clouds cool the planet but are hard to represent because they appear sparse and short-lived. We show that, beneath this appare...
New horizons in statistical downscaling and AI approaches for sustainable km-scale climate simulations [0.03%]
可持续发展的公里尺度气候模拟的统计降尺度和人工智能方法的新进展
Kwok Pan Chun,Leonardo Aragão,Matías Ezequiel Olmo et al.
Kwok Pan Chun et al.
Statistical downscaling translates coarse-resolution climate model output into locally relevant information for climate services and impact assessment. Recent advances in artificial intelligence (AI) enable high-resolution, probabilistic, a...
Global asymmetries in the moisture origins of atmospheric river precipitation [0.03%]
大气河流降水的水分来源的全球不对称性
Alfredo Crespo-Otero,Damián Insua-Costa,Victoria M H Deman et al.
Alfredo Crespo-Otero et al.
Atmospheric rivers (ARs) are key agents of poleward heat and moisture transport, yet the extent to which tropical moisture directly feeds AR precipitation at higher latitudes remains debated. Here we present a forty-year global climatology ...
Constraining the intensive absorption properties of ambient organic aerosol particles based on pan-European observations [0.03%]
基于泛欧洲观测结果限制环境有机气溶胶粒子的密集吸收特性
Jordi Rovira,Jesús Yus-Díez,Gang I Chen et al.
Jordi Rovira et al.
Organic aerosol particles (OA) can absorb solar radiation with varying efficiencies depending on their chemical composition and physical properties. This light-absorbing fraction of OA, commonly referred to as brown carbon (BrC), is difficu...
Projected and historical amplification of moisture fluxes towards Antarctica by synoptic eddies [0.03%]

Synoptic weather systems play a crucial role in transporting moisture to Antarctica. Climate models project significant changes in these systems, including a wintertime intensification and a summertime poleward shift, with implications for ...
Unprecedented 2024 East Antarctic winter heatwave driven by polar vortex weakening and amplified by anthropogenic warming [0.03%]
2024年东南极冬季热浪事件及其引发机制分析：极涡削弱与人类活动增暖的共同作用
Haosu Tang,Sihan Li,Julie M Jones et al.
Haosu Tang et al.
During July-August 2024, East Antarctica experienced the most intense winter heatwave in the 46-year satellite era, with regional mean surface air temperatures across Dronning Maud Land exceeding the climatological mean by more than 9°C fo...
Contextualizing contemporary seasonality variations in East Asian tropical cyclone landfalls with a multi-century historical baseline [0.03%]
基于多世纪历史基准量化东亚热带气旋登陆的年际和年代际变化及其当代季风季节变化 CONTEXTUALIZING CONTEMPORARY SEASONALITY VARIATIONS IN EAST ASIAN TROPICAL CYCLONE LANDFALLS WITH A MULTI-CENTURY HISTORICAL BASELINE
Gan Zhang,Kuanhui Elaine Lin,Dan Fu et al.
Gan Zhang et al.
Paleoclimate records provide a critical long-term perspective on natural climate variability, essential for understanding contemporary climate variations. However, existing paleoclimate proxies lack sufficient spatial-temporal coverage for ...
Seasonal progression of melt and snowlines in Alaska from SAR reveals impacts of warming [0.03%]
基于雷达的阿拉斯加融雪和雪线的季节变化及暖化影响研究表明
Albin Wells,David R Rounce,Mark Fahnestock
Albin Wells
Glaciers in Alaska contribute greatly to sea-level rise and are losing mass at a faster rate than any other region. Yet, our understanding of ongoing changes and ability to model them are hindered by a lack of observations, particularly at ...
Atmospheric water vapor contribution to interannual variability of Northern Hemisphere summer heatwaves [0.03%]
大气水汽对北半球夏季热浪年际变化的贡献
Dingrui Cao,Hai Lin,Yi Huang
Dingrui Cao
Previous studies suggested that atmospheric water vapor, as a greenhouse gas, can amplify surface warming by enhancing downwelling longwave radiation (DLR), thereby potentially intensifying extreme heatwaves. However, the atmospheric water ...
