Tropical isoprene variability differs across three regions
Study reveals tropical isoprene varies by region: Amazonia emission-controlled, Maritime Continent chemistry-controlled, and equatorial Africa intermediate, requiring region-specific atmospheric.
UKESM misses key marine aerosol formation pathways
Evaluation of UKESM1.1 against ATom aircraft data reveals missing marine aerosol formation pathways involving iodine, amines, and organic vapours in remote regions.
Southern land evaporation linked to North China extreme rain
Study identifies atmospheric circulation patterns and cross-regional evaporation precursors driving extreme precipitation trends in North China using information flow analysis.
Coastal aerosol types vary strongly by season worldwide
Analyze seasonal aerosol variations at coastal boundaries using global AERONET data. Machine learning identifies four distinct aerosol regimes with pronounced seasonal patterns and spectral.
Kilometre-scale simulations improved extreme rainfall forecasts in eastern Qinghai
Kilometre-scale convection-permitting simulations significantly improve extreme precipitation forecasting accuracy in Qinghai’s eastern valleys by better representing valley circulation patterns.
Hydrogen contrail ice crystal formation depends on entrained aerosols
Systematic microphysical simulations reveal ice crystal formation mechanisms in hydrogen-combustion contrails, establishing foundation for climate impact parameterization.
Wind shear strengthens soil moisture effects on thunderstorm growth
Wind shear and soil moisture interact to enhance rapid thunderstorm growth, offering new predictability for severe convective initiation across Africa and beyond.
Climate explains mean storm activity more than individual storm features
Machine learning reveals how seasonal climate and synoptic conditions differently control storm activity, with climate trends more strongly affecting storm heat anomalies than intensity.
Ice crystal concentration is the main driver of aggregation rates
Study uses cloud seeding experiments and deep learning to identify ice crystal concentration as the dominant factor controlling aggregation rates in supercooled clouds, with implications for.
Dust layer weakens low-level cloud increase over the North Atlantic
Study quantifies how free-tropospheric Saharan dust over the North Atlantic modulates low-level cloud cover via longwave-induced cloud-top warming that counteracts shortwave-driven cloud enhancement.
