This study examines in detail a continuous drop-size distribution
recorder and selected data gathered with this recorder at
various locations on 6, 15, and 31 May 1966. The drop-size distribution
recorder consists of a self-contained, mobile unit able to
operate without electric power. This recorder utilizes "Ozalid 105
SZ" filter...
The WSR-57 weather radar operated by the National
Weather Service at Sacramento, California, plus a network
of precipitation gages provided data for this comparison
of radar reflectivity with precipitation rates. Located
in a valley with mountains within range of the radar on
three sides, this radar has varying sensitivity for...
One-minute rainrates were measured during two winter rainy
seasons in western Oregon to gain insights into the time-structure of
Oregon rainstorms. The averages of three non-dimensional relative
variance statistics were greater on the coast than inland. Rainrate
distributions showed that a greater portion of the total rain fell, at
higher...
A study was conducted to compare snow accumulation and melt during rainfall in adjacent forest and clearcut plots in the
transient snow zone of the western Cascade Range in Oregon. Snow accumulation differences were determined by comparing the water equivalents of forest and clearcut snowpacks. During rain-on-snow periods, energy balances...
The objective of this study was to ascertain the magnitude and
distribution of rainfall over coastal waters of the northwestern United
States and to compare values with those at nearby land stations.
Precipitation was measured with gauges at Totem, rainfall amounts
were assessed from weather reports at lightships off the...
