Whirling instability of an eccentric coated fibre
François Gallaire, Edouard Boujo, Shahab Eghbali, Ludovic Pierre Gustave Keiser
We study a gravity-driven viscous flow coating a vertical cylindrical fibre. The destabilisation of a draining liquid column into a downward moving train of beads has been linked to the conjunction of the Rayleigh-Plateau and Kapitza instabilities in the l ...
CAMBRIDGE UNIV PRESS2022In-Situ Observations Of Aerosol Hygroscopicity And Cloud Droplet Formation In Ny-Ålesund, Svalbard, During Fall 2019 And Spring 2020
Athanasios Nenes, Ghislain Gilles Jean-Michel Motos, Paraskevi Georgakaki, Jörg Wieder
The Arctic region suffers an extreme vulnerability to climate change, with an increase in surface air temperatures that have reached twice the global rate during several decades (McBean et al., 2005). The role of clouds, and in particular low-levels clouds ...

2021Modeling Extreme Warm-Air Advection in the Arctic During Summer: The Effect of Mid-Latitude Pollution Inflow on Cloud Properties
Usually the Arctic is relatively free of anthropogenic influence in summer, which means that particles from natural sources can be the most significant nuclei for cloud droplets. However, this is not the case during anomalously warm-air intrusions when the ...
2021Quantifying the Impact of Primary vs Secondary Ice Production on Arctic Clouds
Athanasios Nenes, Georgia Sotiropoulou
Ice formation remains among the most poorly understood and hence poorly represented cloud processes in climate models. Primary ice production (PIP) has been recognized as a key process for the correct representation of the modeled cloud feedbacks; secondar ...
American Geophysical Union2021Progress in Unraveling Atmospheric New Particle Formation and Growth Across the Arctic
Julia Schmale, Andrea Baccarini
New particle formation (NPF) and growth can be an important source of cloud condensation nuclei for the Arctic atmosphere, where cloud formation is sensitive to their availability. Low-level clouds influence the Arctic energy budget, and likely contribute ...
2021The acidity of atmospheric particles and clouds
Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the phase partitioning of semivolatile gases such as HNO3, NH3, HCl, and orga ...
2020Properties of Arctic liquid and mixed-phase clouds from shipborne Cloudnet observations during ACSE 2014
This study presents Cloudnet retrievals of Arctic clouds from measurements conducted during a 3-month research expedition along the Siberian shelf during summer and autumn 2014. During autumn, we find a strong reduction in the occurrence of liquid clouds a ...
COPERNICUS GESELLSCHAFT MBH2020Constraining the Twomey effect from satellite observations: issues and perspectives
The Twomey effect describes the radiative forcing associated with a change in cloud albedo due to an increase in anthropogenic aerosol emissions. It is driven by the perturbation in cloud droplet number concentration (Delta N-d, (ant)) in liquid-water clou ...
COPERNICUS GESELLSCHAFT MBH2020Satellite retrieval of cloud condensation nuclei concentrations in marine stratocumulus by using clouds as CCN chambers
A new methodology for the satellite retrieval of cloud condensation nuclei (CCN) in shallow marine boundary layer clouds is developed and validated in this study. The methodology is based on retrieving cloud base drop concentrations (N d ) and updrafts (W ...
