Book excerpt: The primary objectives of the research are to numerically simulate stratus, stratocumulus, and cumulus clouds in the marine boundary layer. This includes the formation, evolution, and dissolution of the clouds and the area covered, then the change from one type of cloud to another would be investigated. Also the change from open cell to closed cell type convection and the formation of cloud streets could investigated.

This book was released on 2016 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extensive coverage of low clouds over the subtropical eastern oceans greatly impacts the current climate. In addition, the response of low clouds to changes in atmospheric greenhouse gases and aerosols is a major source of uncertainty, which thwarts accurate prediction of future climate change. Low clouds are poorly simulated in climate models, partly due to inadequate long-term simultaneous observations of their macrophysical and microphysical structure, radiative effects, and associated aerosol distribution in regions where their impact is greatest. The thickness and extent of subtropical low clouds is dependent on tight couplings between surface fluxes of heat and moisture, radiative cooling, boundary layer turbulence, and precipitation (much of which evaporates before reaching the ocean surface and is closely connected to the abundance of cloud condensation nuclei). These couplings have been documented as a result of past field programs and model studies. However, extensive research is still required to achieve a quantitative understanding sufficient for developing parameterizations, which adequately predict aerosol indirect effects and low cloud response to climate perturbations. This is especially true of the interactions between clouds, aerosol, and precipitation. These processes take place in an ever-changing synoptic environment that can confound interpretation of short time period observations.

Available in PDF, EPUB and Kindle. Book excerpt: A coupled convective-radiative, boundary-layer model of marine stratocumulus clouds is presented. The model, which slightly generalized Lilly's (1968) cloud-topped mixed-layer model, has as dependent variables the cloud-top height, the cloud-base height, mixed-layer equivalent potential temperature and total water mixing ratio, the turbulent fluxes of equivalent potential temperature, total water mixing ratio, and virtual potential temperature, the cloud-top jumps of equivalent potential temperature and total water mixing ratio, the cloud-top temperature, and the net radiative flux divergence at cloud top and in the mixed layer. Keywords: Stratosphere. (EG).

This book was released on 2021 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A multi-day period (February 23-26, 2018) of post-frontal shallow convective mixed-phase clouds observed during the shipborne Measurements of Aerosols, Radiation and CloUds over the Southern Ocean (MARCUS) field campaign is studied using the Weather Research and Forecast (WRF) model with the aim of understanding ice production as well as model sensitivity to ice process parameterizations. The Cloud-resolving model Radar SIMulator (CRSIM) is firstly used in this study to convert WRF S-band output into W-band radar observables. Comparisons between the observations and simulations suggest that the model captures the observed synoptic pattern and shallow convective nature of the mixed-phase clouds. The simulated clouds are mostly precipitating and liquid dominated. Interestingly, the control simulation significantly underestimates the ice content and overestimates the supercooled liquid water, which is contrary to the bias common in global climate models. Sensitivity simulations targeted at ice production processes suggest that the rime splintering process is not a primary contributor and that the simulated clouds show negligible sensitivity to cloud droplet number concentrations. Higher number concentrations of ice nuclei do not guarantee more ice production overall. However, the simulated mixed-phase clouds are found to be highly sensitive to the implementation of immersion freezing and condensation/deposition freezing. By increasing immersion freezing of cloud droplets or relaxing thresholds for condensation/deposition freezing, the model significantly improves its performance in producing ice. The key results of this work call for an increase in observations of ice nuclei, especially over the remote Southern Ocean and at relatively high temperatures.
