Aerosol invigoration and restructuring of Atlantic convective clouds
[1] Clouds and precipitation play crucial roles in the Earth’s energy balance, global atmospheric circulation and the availability of fresh water. Aerosols may modify cloud properties and precipitation formation by modifying the concentration and size of cloud droplets, and consequently the strength of cloud convection, and height of glaciation levels thus affecting precipitation patterns. Here...
متن کاملObservations of aerosol-induced convective invigoration in the tropical east Atlantic
Four years of CloudSat data have been analyzed over a region of the east Atlantic Ocean in order to examine the influence of aerosols on deep convection. The satellite data were combined with information about aerosols taken from the Global and Regional Earth-System Monitoring Using Satellite and In Situ Data model. Only those profiles fitting the definition of deep convective clouds were analy...
متن کاملA theoretical basis for a nanomolar critical oxygen concentration
When aerobic microbes deplete oxygen sufficiently, anaerobic metabolisms activate, driving losses of fixed nitrogen from marine oxygen minimum zones. Biogeochemical models commonly prescribe a 1–10 lM critical oxygen concentration for this transition, a range consistent with previous empirical and recent theoretical work. However, the recently developed STOX sensor has revealed large regions wi...
متن کاملCompetition between core and periphery-based processes in warm convective clouds – from invigoration to suppression
How do changes in the amount and properties of aerosol affect warm clouds? Recent studies suggest that they have opposing effects. Some suggest that an increase in aerosol loading leads to enhanced evaporation and therefore smaller clouds, whereas other studies suggest clouds’ invigoration. In this study, using an axisymmetric bin-microphysics cloud model, we propose a theoretical scheme that a...
