Wet scavenging limits the detection of aerosol–cloud–precipitation interactions by Gryspeerdt, E, Stier, P, White, B, Kipling, Z

“…Generally, the smaller spatial variability of aerosols compared to clouds reduces the importance of this sampling difference. However, as precipitation generates an increase in spatial variability, the imperfect co-location of aerosol and cloud property retrievals may lead to changes in observed aerosol–cloud–precipitation relationships in precipitating environments. …”

An energetic view on the geographical dependence of the fast aerosol radiative effects on precipitation by Dagan, G, Stier, P, Watson-Parris, D

“…By interacting with radiation, aerosols perturb the Earth&rsquo;s energy budget and thus the global precipitation amount. It was previously shown that aerosols lead to a reduction in the global-mean precipitation amount. …”

On the contribution of fast and slow responses to precipitation changes caused by aerosol perturbations by Stier, P, Watson-Parris, D, Zhang, S

“…Changes in global-mean precipitation are strongly constrained by global radiative cooling, while regional rainfall changes are less constrained because energy can be transported. …”

Dependence of fast changes in global and local precipitation on the geographical location of absorbing aerosol by Williams, A, Watson-Parris, D, Dagan, G, Stier, P

“…Anthropogenic aerosol interacts strongly with incoming solar radiation, perturbing Earth’s energy budget and precipitation on both local and global scales. Understanding these changes in precipitation has proven particularly difficult for the case of absorbing aerosol, which absorbs a significant amount of incoming solar radiation and hence acts as a source of localized diabatic heating to the atmosphere. …”

Constraint on precipitation response to climate change by combination of atmospheric energy and water budgets by Dagan, G, Stier, P

“…Global mean precipitation is expected to increase with increasing temperatures, a process which is fairly well understood. …”

“…Global mean precipitation changes due to climate change were previously shown to be relatively small and well constrained by the energy budget. …”

Isolating large-scale smoke impacts on cloud and precipitation processes over the Amazon with convection permitting resolution by Herbert, RJ, Stier, P, Dagan, G

“…We show ARI influences the formation and development of convective cells: surface cooling below the smoke drives suppression of convection that increases with smoke optical depth, whilst the elevated heating promotes initial suppression and subsequent intensification of convection overnight; a corresponding diurnal response (repeating temporal response day-after-day) from high precipitation rates is shown. Enhanced Nd (ACI) perturbs the bulk cloud properties and suppresses low-to-moderate precipitation rates. …”

Rainfall-aerosol relationships explained by wet scavenging and humidity by Grandey, B, Gururaj, A, Stier, P, Wagner, T

Water vapour adjustments and responses differ between climate drivers by Hodnebrog, O, Myhre, G, Samset, B, Alterskjaer, K, Andrews, T, Boucher, O, Faluvegi, G, Fläschner, D, Forster, P, Kasoar, M, Kirkevag, A, Lamarque, J, Olivie, D, Richardson, T, Shawki, D, Shindell, D, Shine, K, Stier, P, Takemura, T, Voulgarikis, A, Watson-Parris, D

“…Water vapour in the atmosphere is the source of a major climate feedback mechanism and potential increases in the availability of water vapour could have important consequences for mean and extreme precipitation. Future precipitation changes further depend on how the hydrological cycle responds to different drivers of climate change, such as greenhouse gases and aerosols. …”
