Short summary
Short summary
This study identifies a previously unrepresented process, Recondensation-Induced Nucleation (RIN), linking combustion microphysics to ambient ultrafine particle formation. Laboratory engine experiments, parcel modeling, and Community Multiscale Air Quality (CMAQ) simulations show that including RIN can significantly reduce number concentration underestimation from 75 % to 22 % while maintaining PM2.5 accuracy, providing a mechanistic basis for improving urban aerosol modeling.

Short summary
We studied nitrogen pollution in Taiwan's mountain forests to track how urban emissions reach and transform in remote areas. Isotope analysis and statistical modeling revealed that combustion sources contributed 50–83 % of ammonia, while nitrate forms continuously from urban to rural sampling sites. The findings show that persistent urban pollution strongly impacts mountain ecosystems, offering key insights for air quality management.

Short summary
We developed a new cloud microphysics scheme that links simulated cloud and precipitation particles with radar signals. Idealized squall line and a real thunderstorm case in Taiwan show that the scheme produces physically meaningful storm structures and encouraging radar comparisons, while further refinement is still needed for ice particles, hydrometeor orientation, and radar-viewing assumptions.

Short summary
In conventional models, isotope exchange between liquid and gas phases is usually assumed to be in equilibrium, and the highly kinetic phase transformation processes inferred in clouds are yet to be fully investigated. We show that different factors controlling isotopic composition, including water vapor sources, atmospheric transport, phase transition pathways of water in clouds, and kinetic-versus-equilibrium mass transfer, contributed significantly to the variations in isotope composition.
In conventional models, isotope exchange between liquid and gas phases is usually assumed to be...
