This research consists of two related yet distinct
studies: an observational study of the surface character of
the penetration of marine air into the southern Willamette
Valley and a climatological study of the summertime air
masses of northwestern Oregon.
For the observational study, temperature and estimated
wind data were gathered by automobile. Mesoscale analysis
of several cases indicate that the Marine Air Penetration
(MAP) occurs regularly in approximately the same area and
is strongly controlled by the topography. Qualitative
observation and reasoning strongly suggests that the strong
winds and increased stability at the top of the marine layer
have an adverse effect upon agricultural field fires.
Results of the climatological study indicated that the
application of the partial collective method of analysis to
July maximum temperature data from the U.S. Climatological
Network yielded a meaningful air mass climatology for northwestern Oregon. To our knowledge, this is the first time that the partial collective method has been applied to a
region with mountainous areas west of the Rocky Mountains or
to the mesoscale. / Graduation date: 1981
