“…The modes of these larger droplet sizes are comparable to shallow cumulus large modes at 22 and 20 μm reported by Schmeissner et al (2015) and Brenguier et al (2011). Gultepe et al (2021) report a large mode of 25 μm for a stratus base lowering case in Newfoundland, with a primary mode at around 15 μm. Wagh et al (2021) later showed that this peak varied between 20 and 25 μm and was indicative of droplet growth by collision and coalescence.…”

“…Fog microphysics were measured with a Fog Monitor 120 (FM-120) from Droplet Measurement Technologies. This instrument is used widely for fog measurements which makes for consistent comparison of results with other studies (Gonser et al, 2011;Gultepe et al, 2009Gultepe et al, , 2021Mazoyer et al, 2019;Niu et al, 2010;Spiegel et al, 2012). This instrument is a forward scattering spectrometer probe, where the droplet size is calculated based on scattered light from a laser and employing Mie theory.…”

Fog occurs when condensation processes in the atmosphere allow for cloud droplet formation near the Earth's surface causing visibility to drop below 1 km (World Meteorological Organization, 2008). Fog has a major impact on society, most notably on the functioning of transportation networks, as the low visibility can result in delays or create hazardous conditions. Different fog types have been described in the literature and are essentially categorized based on the source of moisture and the mechanism through which the air temperature reaches the dew point temperature. These include precipitation, radiation, advection, cloud-base lowering, morning evaporation, advective-radiation and high fog (

“…Besides topography, the proximity to the sea is also important for the timing of FLS formation and dissipation. In general, coastal fog is strongly influenced by the meteorological conditions and ocean–atmosphere interactions (Gultepe et al ., 2021). The results presented here show a clear pattern of FLS formation at sunrise at the coast of the Mediterranean Sea in summer (Figure 9).…”

Knowledge of fog and low stratus (FLS) cloud patterns and life cycles is important for traffic safety, for the production of solar energy and for the analysis of cloud processes in the climate system. While meteorological stations provide information on FLS, a data set describing FLS formation and dissipation times on large spatial and temporal scales does not yet exist. In this study, we use logistic regression to extract FLS formation and dissipation times from a satellite-based 10-year FLS data set covering central Europe. The resulting data set is the first to provide a geographic perspective on FLS formation and dissipation at a continental scale. The patterns found show a clear dependency of FLS formation and dissipation times on topography. In mountainous areas, FLS forms in the night and dissipates in the morning. In river valleys, the typical FLS life cycle shifts to formation after sunrise and dissipation in the afternoon. Seasonal patterns of FLS formation and dissipation show similar FLS formation and dissipation times in winter and autumn, and in spring and summer, with longer events in the former two seasons.

Recent rapid industrial development in the Korean Peninsula has increased the impacts of meteorological disasters on marine and coastal environments. In particular, marine fog driven by summer cold water masses can inhibit transport and aviation; yet a lack of observational data hinders our understanding of this phenomena. The present study aimed to analyze the differences in cold water mass formation according to sea surface temperature (SST) resolution and its effects on the occurrence and distribution of sea fog over the Korean Peninsula from June 23–July 1, 2016, according to the Weather Research and Forecasting model. Data from the Final Operational Model Global Tropospheric Analyses were provided at 1° and 0.25° resolutions and NOAA real-time global SST (RTG-SST) data were provided at 0.083°. While conventional analyses have used initial SST distributions throughout the entire simulation period, small-scale, rapidly developing oceanic phenomena (e.g., cold water masses) lasting for several days act as an important mediating factor between the lower atmosphere and sea. RTG-SST was successful at identifying fog presence and maintained the most extensive horizontal distribution of cold water masses. In addition, it was confirmed that the difference in SST resolution led to varying sizes and strengths of the warm pools that provided water vapor from the open sea area to the atmosphere. On examining the horizontal water vapor transport and the vertical structure of the generated sea fog using the RTG-SST, water vapors were found to be continuously introduced by the southwesterly winds from June 29 to 30, creating a fog event throughout June 30. Accordingly, high-resolution SST data must be input into numerical models whenever possible. It is expected that the findings of this study can contribute to the reduction of ship accidents via the accurate simulation of sea fog.
