Vertical Dependency of Aerosol Impacts on Local Scale Convective Precipitation

Geophysical Research Letters, Journal Year: 2023, Volume and Issue: 50(2)

Published: Jan. 18, 2023

Abstract Aerosol effects on convective precipitation is critical for understanding human impacts extreme weather and the hydrological cycle. However, even their signs magnitude remain debatable. In particular, aerosol vertical structure of have not been systematically examined yet. Combining 6‐year space‐borne ground‐based observations over North China Plain, we show a boomerang‐shape effect top height precipitation, from invigoration to suppression. Further analyses reveal that aerosols play distinct rate at different layers. Particularly, near surface shows no significant responses precipitation‐top due strong evaporation. The competition energy between released condensation freezing absorbed by evaporation contributes can explain effect.

In recent decades, the Beijing-Tianjin-Hebei city cluster is experiencing rapid urbanization along with economic booming. Meanwhile, these cities are suffering influence of extreme precipitation and dust storms. this study, impact aerosol on that occurred in Beijing during 19–21 July 2016 investigated using both satellite retrievals Weather Research Forecasting model coupled to Chemistry (WRF-Chem) simulations. Results reveal particles can increase by promoting formation ice clouds enhancing convections. The lifted into upper troposphere (>10 km) via strong convection affects physical process after long-range transport. It further transforms supercooled water middle high levels nuclei (IN). These promote according decreased effective radius IN increased path, respectively. Along sufficient vapor transport convergence, could release more latent heat strengthen development. Thus, amount southern almost enhanced 40 % (>80 mm). This study will provide a deep insight understanding causes urban precipitation.

Distinct effects of fine and coarse aerosols on microphysical processes of shallow-precipitation systems in summer over southern China

Atmospheric chemistry and physics, Journal Year: 2025, Volume and Issue: 25(3), P. 1587 - 1601

Abstract. Densely populated southern China, adjacent to the South China Sea, which is associated with shallow precipitation during summer, an open-air natural laboratory for studying impact of aerosol particles on shallow-precipitation events. Using 8 years data from Dual-frequency Precipitation Radar measurements, reanalysis, and atmospheric this study investigates potential influence coarse fine structure microphysical processes in China. Statistical results indicate that coarse-aerosol-polluted conditions, clouds have a lower mean height storm top (STH; ∼3.2 km) but higher near-surface rain rate (RR; ∼1.78 mm h−1) are characterized by high concentrations large raindrops, driven mainly significant collision–coalescence (accounting 74.1 %). In contrast, fine-aerosol-polluted develop deeper median STH ∼3.7 km surface RR low concentration small resulting increased breakup (33.1 %) reduced (69.6 The (fine) act as promoters (inhibitors) radar reflectivity profile precipitation, regardless dynamic humid conditions. effect promoting inhibiting most under low-humidity attributed significantly enhanced processes, exceeding 22.2 %. Furthermore, increase above 3 environments hydrometeors low-instability whereas it high-instability environments.
