Special Issue Information

Dear Colleagues,

Cloud microphysical processes are one of the key factors for quantitatively modeling precipitation and are strongly linked to the global radiative and hydrological fluxes. Cloud microphysical processes are the fundamental theory of weather modification and are closely linked to the progresses of physical chemistry, radiative properties, and kinetics of small solid and liquid aqueous particles. Additionally, to improve our understanding of the aerosol–cloud interactions, we need to advance our knowledge of the cloud microphysical processes. Therefore, we are pleased to announce a call for papers for the Special Issue on “Microphysics of Cloud Processes (MCP)”. This issue aims to provide a platform for researchers to share their latest findings and advancements in this area. In order to promote a diverse range of perspectives and approaches to this topic, we welcome submissions from researchers in both field measurements and simulation studies. We encourage researchers to submit papers on the following topics or any other relevant research associated with cloud microphysical processes.

Topics of interest for the Special Issue include, but are not limited to:

  • The modeling and observation of cloud microphysical processes;
  • Aerosol–cloud interactions;
  • Airborne observation of cloud particles;
  • Modeling and observation of CCN and IN;
  • Interactions between cloud microphysics processes and cloud scale dynamics.

Using the high-resolution numerical weather research and forecasting (WRF) model, study the squall line process that occurred on Hainan Island on 22 April 2020. The findings indicate that high terrain blocks the swift accumulation of water vapor carried by the sea breeze and aids in preserving the accumulated water vapor. According to the sensitivity experiment, terrain height has minimal impact on the macroscopic effects of mesoscale weather processes. However, it does influence where the sea breeze converges. During this process, the ocean-land thermal contrast not only takes the main responsibility for the sea breeze but also leads to uplift motion, which affects the formation, intensity, and duration of the squall line. Additionally, the unstable conditions suggest that a thermal and dynamic environment promote the scale of this squall line. Utilizing the Rotunno–Klemp–Weisman theory (RKW), this study analyzes the effects of the cold pool and vertical wind shear. The analysis reveals that significant vertical wind shear at lower levels and the ground-cold pool contribute to the sustenance and growth of the squall line system. This squall line process has had the greatest impact on the Haikou area due to the strong low-level vertical wind shear and prolonged interaction with the cold pool. When the interaction between the cold pool and the vertical wind shear weakens, the squall dissipates. Full article

The measurement of cloud microphysical parameters plays an important role in describing characteristics of liquid phase clouds and investigating mutual relationships between clouds and precipitation. In this paper, cloud microphysical parameters at Liupan Mountain Weather Station in Ningxia are measured with a high-resolution coaxial digital holographic imager and a fog monitor 120. There are differences in the measurement results between the two instruments. The number concentration measured by the digital holographic imager is about 1.5 times that of the fog monitor 120. However, their Pearson correlation coefficient is above 0.9. Through analysis, we found that the measurement results of the digital holographic imager and fog monitor 120 are differences in 2–4 µm and 7–50µm. For the droplets with the diameters of 4–7 µm, their measurement results have good consistency. By analyzing the influence of wind field and detection sensitivity on the measurement principle, the reasons which caused the difference are proposed. Advice is given to observe topographic clouds by using the above two instruments. In addition, the differences in liquid water content and visibility are analyzed due to the absence of small and large droplets. The study provides data support for improving the accuracy of instruments in measuring cloud droplets and is useful for research in the field of cloud microphysical processes. Full article
