A Climatology of Mountain Fog on Mauna Loa, Hawai'i Island

摘要

This study investigates spatial and climatological aspects of the mountain fog regime on Mauna Loa, Hawai'i Island. A louvered-screen fog gage was developed for standardized measurement of fog interception together with a methodological technique for isolating the fog component of precipitation episodes on the basis of fog and rain-gage geometry and the physical relationship between droplet size, inclination angle, and wind speed. In addition, methods for relating mechanical fog interception data to actual forest fog drip are investigated.
