The high-latitude winter atmospheric boundary layer of interior Alaska continually exhibits a complex layered structure as a result of extreme meteorological conditions. In this paper the occurrence of elevated inversions (EI), surface-based inversions (SBI), and stratified layers in the sub-Arctic from January 2000 to December 2009 is reported. This statistical analysis is based on radiosonde observation data from the Fairbanks National Weather Service station complemented by Winter Boundary Layer Experiment observations in the period 2010-11. This study found that SBIs occurred 64% of the time. An SBI occurred in combination with one, two, three, or four simultaneous EIs 84.86%, 48.49%, 21.23%, and 7.99% of the time, respectively, in 2326 total cases. The calculated mean SBI height was 377 m; EIs occurred at 1231, 2125, 2720, and 3125 m, respectively. This analysis was able to discriminate between locally controlled inversion layers and synopticdependent inversions and to identify their formation mechanisms. It was found that, in the presence of an SBI layer, the first EI layer formed 35.8% of the time under anticyclonic conditions at a mean height of 1249 m and 22% of the time in warm-air-advection situations at a mean height of 1049 m. The remaining 23.4% resulted from combined synoptic situations, and 18.8% were unclassified.

“…Digital elevation model of the interior of Alaska. Under an AC condition, upper-level subsidence warms the atmospheric layer above the SBI, creating another higher-level inversion without the requirement of warm advection aloft (Wexler 1941;Bowling et al 1968). Heights are in meters above mean sea level (MSL).…”

“…A timely prediction of high-pressure systems over cold climates and generation of a BL inversion can play an important role in ice fog/cloud formation (Bowling et al 1968;Gultepe et al 2015). On the other hand, over marine environments, advection of moist and warm air over a cold ocean or land surface can also generate fog and low-level ice clouds (or supercooled fog clouds) (Gultepe 2015).…”

“…Their project focused mostly on fog microphysics and chemistry as in the previous field experiment. Ice fog studies (BOWLING et al, 1968;GIRARD and BLANCHET, 2001;GOTAAS and BENSON, 1965) were limited due to the difficulties of measurement ice particles at sizes less than 100 lm (GULTEPE et al, 2001). However, Gotaas and Benson results showed that 10°C/day cooling was due to ice fog occurrence on January 1962.…”

The scientific community that includes meteorologists, physical scientists, engineers, medical doctors, biologists, and environmentalists has shown interest in a better understanding of fog for years because of its effects on, directly or indirectly, the daily life of human beings. The total economic losses associated with the impact of the presence of fog on aviation, marine and land transportation can be comparable to those of tornadoes or, in some cases, winter storms and hurricanes. The number of articles including the word ''fog'' in Journals of American Meteorological Society alone was found to be about 4700, indicating that there is substantial interest in this subject. In spite of this extensive body of work, our ability to accurately forecast/nowcast fog remains limited due to our incomplete understanding of the fog processes over various time and space scales. Fog processes involve droplet microphysics, aerosol chemistry, radiation, turbulence, large/small-scale dynamics, and surface conditions (e.g., partaining to the presence of ice, snow, liquid, plants, and various types of soil). This review paper summarizes past achievements related to the understanding of fog formation, development and decay, and in this respect, the analysis of observations and the development of forecasting models and remote sensing methods are discussed in detail. Finally, future perspectives for fog-related research are highlighted.
