A radar echo-contour height measurement at different gain
settings of the receiver, from RHI pictures shows that heavy rain
occurs at the points above which steep echo-contour gradients appear.
In this study, radar data came from the AN/CPS-9 radar
located at McCulloch peak, about five miles from the Oregon State...
The Late Spring Secondary Precipitation Maximum in the
Interior Pacific Northwest results from a complex system of climatic
controls. The Secondary Maximum is most strongly developed over the
high plateau of Oregon immediately in the lee of the Cascade
Mountains. Local topographic
organization exerts strong control
over the magnitude and...
Mathematical models of the precipitation process are needed to
effectively use historical precipitation data in the design and
planning of engineering projects and for analysis of watershed
runoff behavior. Existing simple models based on the assumptions of
independent, identically-distributed random variables are
insufficient to describe several features of the historical...
The Weather Radar Set An/CPS-9 at McCulloch Peak,
Oregon, provided data of changes in radar precipitation
echo patterns in the vicinity of Marys Peak. Echo heights
studied from data collected on 14 March 1963 averaged nearly
the same upwind, directly over Marys Peak, and downwind.
For the data of 28...
Precipitation occurrence in three winter periods and three
summer periods is examined for two Oregon stations: Seaside and
Squaw Butte. The winter periods are January, February, and the
interval January 15 to February 20. The summer periods are July,
August, and the interval July 10 to August 15. The two...
