The climate and the exchange of heat between atmosphere and
ocean are examined in a region adjacent to Washington and Oregon,
and in two sub-regions adjacent to Oregon. The sub-regions are
chosen such that one contains the nearshore upwelling region and the
other borders it on the seaward side.
The data (ship weather observations, 1953 to 1962) reveal the
general seasonal variation of climatic factors in the regions studied
and the effects of the nearshore upwelling of cold water on the climate
over the coastal ocean region and the adjacent coastal land mass. In
the nearshore sub-region, summer values of temperature (air, wet
bulb, and sea surface) are lower than those to seaward, but winter
values are higher inshore than to seaward. The effects of these differences,
and of other factors, on the heat exchange processes are
examined with the use of empirical equations. It is seen that the processes
of evaporation and conduction are suppressed considerably
and net long wave radiation is slightly suppressed in the upwelling
region during the summer.
The effects of the reduction of heat loss to the atmosphere in
the summer upwelling region on the climate of coastal Oregon are
seen to be a slight reduction of air temperatures and, despite reduced
evaporation, a very slight increase of relative humidity.
Monthly means of daily net heat exchange between the sea and
the atmosphere are examined and correlated with the difference between
monthly means of the heat used per day in the oceanic evaporation
process and the monthly means of daily totals of heat estimated to be
used in the evaporation from a shallow pan under climatic conditions
identical to those accompanying the net heat exchange and oceanic
evaporation. / Graduation date: 1965
