Vertical Dependency of Aerosol Impacts on Local Scale Convective Precipitation

Abstract

Precipitation is a fundamental driver of the global hydrological cycle and has profound implications on human life and social society (

Microphysical Characteristics of Precipitation Over Eastern China and Its Coastal Regions

“…If the precipitation top height is above (below) the freezing level, the precipitation case is defined as cold‐topped (warm‐topped) precipitation (Y. Sun et al., 2023). When investigating the profiles of precipitation, this study excludes the samples with noisy signals by removing the cases that have a maximum 20 dBZ echo top greater than 17 km and a case number less than 30 (C. Liu & Zipser, 2015; Wilks, 2011).…”

“…Except for light convective precipitation, cold-topped precipitation dominates in the remaining cases. Light convective precipitation is generally thermally driven precipitation over land, while is more likely isolated precipitation cells over ocean (T. Iguchi et al, 2010;Schumacher & Funk, 2023;Y. Sun et al, 2023).…”

“…Aerosols can also reduce the mean droplet concentration in most regions but increase the effective radius of precipitation through microphysical effects (N. Sun et al, 2022). Therefore, it is necessary to comprehensively investigate the precipitation characteristics over different underlying surfaces and different latitudes, and understand the differences by taking both dynamics and thermodynamics into consideration (e.g., Koren et al, 2012;Y. Sun et al, 2023).…”

“…Therefore, it is necessary to comprehensively investigate the precipitation characteristics over different underlying surfaces and different latitudes, and understand the differences by taking both dynamics and thermodynamics into consideration (e.g., Koren et al., 2012; Y. Sun et al., 2023). This is also what this study aims to do.…”

“…For example, aerosols can modify precipitation time, intensity, and frequency (Y. Sun & Zhao, 2021; N. Sun et al., 2022, 2023) by heating or cooling the atmosphere through radiative effects. Aerosols can also reduce the mean droplet concentration in most regions but increase the effective radius of precipitation through microphysical effects (N. Sun et al., 2022).…”
