Study of Rain Versus Snow at Otis Air Force Base During the Winter Season of 1966-1967

摘要

The thickness patterns 1000 - 850 MB, 1000 - 7000 MB, 1000 - 5000 MB for the winter season 1966 - 1967 were investigated using the ACK sounding plus temperatures at the 850 and 700 MB level to determine the possibility of the occurrence of snow and/or rain at Otis AFB. Furthermore, consideration was given to the precipitable water values from Nantucket and compared with the recorded water amounts at Otis. During the winter season 1966 - 1967 twenty-five case studies were investigated. Results are very promising. Graph C, 1000 - 700 MB Thickness vs 850 MB Temperature indicates the possibility in determining the state of the precipitation on a six-hour forecast basis at Otis AFB. (Author)
