| Summary: | Marine stratocumulus clouds are the predominant cloud type in the mid-latitudes and have significant impact on the Earth’s radiation budget. The transition of marine boundary layer clouds from single-layer stratocumulus to broken cloud structures frequently occurs in response to increasing sea surface temperature and involves three stages: the deepening of the stratocumulus deck, the formation of cumulus beneath the stratocumulus, and the dissipation of stratocumulus layer. In this dissertation, the characteristics of each transition stage, including microphysical properties, thermodynamics, drizzle, and dynamics are investigated using observational data collected at the Atmospheric Radiation Measurements (ARM) ENA facility during the summers between 2016 and 2019. The relationships between biogenic gas dimethyl sulfide (DMS) and cloud radiative properties are studied using aircraft measurements in Chapter 2. Weak correlations are found between DMS concentration and cloud effective radius in well-mixed ... |
