Mesoscale-cellular convective (MCC) organisation is frequently observed in Southern Ocean (SO) stratocumuli, which exert a climate relevant cloud radiative effect in this region. Furthermore, many of these clouds are not pure liquid clouds, but contain a mixture of ice and liquid.
McCoy et al. (2017) demonstrated that the cloud albedo and thus the shortwave cloud-radiative effect of SO...
The influence of aerosol on precipitation in shallow clouds is a topic of longstanding interest. We will address the case of aerosol effects on warm trade-wind cumulus and show that the cloud system develops spatial organization structures in such a way as to generate similar amounts of precipitation, regardless of the aerosol input.
In aerosol-poor conditions, precipitation formation is...
Uncertainty in the response of clouds to warming is the leading source of uncertainty in projections of future warming. To a large fraction the frequently occurring shallow cumulus clouds in the trade wind region contribute to this uncertainty. In symbiosis with thin clouds of stratiform extent they often create various cloud patterns.
These cloud patterns are detected with a neural...
Quantifying, interpreting and classifying meso-scale patterns in shallow trade wind cloud fields has recently received considerable attention. Typical patterns have i.a. been identified by [expert visual inspection][1], [machine learning][2] and several ["organisation metrics"][4]. We investigate the hypothesis that such typical patterns correspond to attractive steady states, i.e. states...
