Army Material Command, Alexandria, Va.IABSTRACT-The heavy fog statistics for 244 first-order distribution was compared with existing analyses and wasweather stations were used to generate experimental ob- found to be in reasonable agreement. The maps of monthlyjective analyses of the annual and monthly geographic distribution of fog are presented as a new contribution fordistribution of heavy fog

Weather Bureau'(Original manuscript received 15 December 1954; wvised manuscript received 18 June 1955) ABSTRACTMeasurements of droplet count have been made in fogs, natural clouds, and laboratory clouds. All dropletslarger than 0.75-micron radius that were contained in a small volume (approximately 1 cubic centimeter) ofthe cloud were included

WOODCOCKDepartment of Oceanography, University of Hawaii, Honolulu, HI 96822(Manuscript received 29 September 1983, in final form 4 February 1984)ABSTRACTNew observations confirm the formation of advective fogs over the western approaches to the Cape CodCanal. The large air-water temperature differences required for the formation of these fogs are shown to occurwhen the colder Cape Cod Bay waters

OCTOBER 1961RALPH G. ELDRIDGE671A FEW FOG DROP-SIZE DISTRIBUTIONS Ralph G. EldridgeTechnical Operations, Inc., Burlington, Mass.(Manuscript received 19 September 1960)ABSTRACTAn independent calibration of an instrument called a Particle Counter and the resulting fog drop-sizedistributions are discussed. The distributions exhibit an increasing number of droplets with decreasingsize. The magnitude of the sampling error inherent in the instrument is inferred from a speculative argumentbased on

1. Chapter overview Ice fog has taken on a number of names since early times. According to the AMS Glossary of Meteorology ( American Meteorological Society 2017 ), ice fog is also known as ice crystal fog, frozen fog, ice crystal haze, Arctic mist, frost fog, frost flakes, air hoar, rime fog, or pogonip. Likewise, there are dozens of other names, in other languages, for this phenomenon. Strictly speaking, however, since we will be discussing fog that consists only of suspended ice crystals
