Abstract:This study investigates the mountain fog regime on the windward and leeward slopes of Mauna Loa, Hawaii. Methodological approaches utilized in the study included: 1) development of a standardized louvered screen fog gage; 2) development of an indirect approximation method for estimating average droplet sizes during precipitation episodes and for separating the rain and fog components; 3) establishment of an extensive fog sampling network on the windward and leeward slopes of Mauna Loa; and 4) development of an original computer program for detailed temporal and spatial analysis of rain, fog and wind parameters. An analysis of mountain fog data for the period 1974 - 1976 yielded the following conclusions: 1) a well defined fog belt exists on windward Mauna Loa in the altitudinal zone between 1500 - 2500m; 2) on leeward Mauna Loa mountain fog increases with elevation up to at least 2000m, with fog amounts lower than at comparable elevations on the windward slope; 3) seasonal and altitudinal patterns in fog frequency and intensity are related to the dynamic interaction of the trade wind field (particularly the trade wind inversion)and the local land/sea breeze regime; 4) mountain fog appears to be a significant factor in the water balance of mountain ecosystems on Mauna Loa; 5) the potential for large scale mechanical recovery of fog water for domestic and agricultural water supply may be feasible for limited areas of the mountain slope.
