Abstract: A total of 98 three-dimensional large-eddy simulations (LESs) of marine stratocumulus clouds covering both nighttime and daytime conditions were performed to explore the response of cloud optical depth (τ) to various aerosol ...

Abstract: Significant enhancements in humidity around cumulus clouds, that is, the ?cloud halos? observed in many aircraft penetrations, are simulated using a three-dimensional dynamic model. Five case studies show that humidity ...

Abstract: Regions of enhanced humidity in the vicinity of cumulus clouds, so-called cloud halos, reflect features of cloud evolution, exert radiative effects, and may serve as a locus for new particle formation. Reported here are ...
