Variations in drop-size distributions as measured with a continuous raindrop recorder and compared to radar echo characteristics

Creator:: Hutcheon, Richard J. (Richard James)
Abstract:: 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...

A study of the relation between radar and raingage indicated rainfall over northern California

Creator:: Strem, Eric Thomas
Abstract:: 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...

Fine-scale time variations of rainfall

Creator:: Trump, Clifford Lyons
Abstract:: 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...

Comparitive snow accumulation and melt during rainfall in forest and clearcut plots in western Oregon

Creator:: Berris, Steven Neil
Abstract:: 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...

Rainfall over coastal waters of the Pacific Northwest

Creator:: Reed, Ronald Keith
Abstract:: 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...

Modeling of point rainfall processes in the Republic of Cape Verde

Creator:: Lenhart, James H.
Abstract:: The rainfall regime of the Cape Verde Islands is influenced by the Intertropical Convergence Zone (ITCZ) resulting in strong seasonal trends and frequent thunderstorm events. These events are frequently responsible for the destruction of riverine structures and valuable crop land. A menu driven database program (RIS) was developed for the...

An analysis of the distribution of precipitation and runoff from the historical record for the continental United States

Creator:: Dolph, Jayne Ellen
Abstract:: Characterizing the distribution of precipitation at regional scales is a requirement for the development of regional scale, spatially distributed hydrologic water balance models. This study performs a preliminary assessment of the utility and limitations of historical hydro-meteorological data for providing spatially distributed precipitation estimates over large areas. The historical data...

The effects of rainfall on temperature and salinity in the surface layer of the equatorial Pacific

Creator:: Bahr, Frederick L.
Abstract:: Measurements of temperature and salinity in the upper 5 m of the ocean along the equator showed cool fresh anomalies due to rain showers. The measurements were made between 140 W and 110 W during April 1987, an El Nino year. The eastern equatorial Pacific was characterized by weak winds...

Experimental and analytical investigation of ponding load effects on a steel joist roof system

Creator:: Stark, Duncan
Abstract:: Ponding of water on roof systems leading to collapse causes expensive damage and jeopardizes the life safety of building occupants. Current building codes and design specifications for flat roof systems offer minimal guidance in designing for ponding loads. The present research investigated ponding load effects on a long span, lightweight...

Make it Rain : A Lagrangian Approach to Investigate Land Surface Controls on Moisture Recycling in the Columbia River Basin

Creator:: Tai, Leah Chung-Mei
Abstract:: Linkages between land use and its influence on the atmosphere have been a long-standing research area. For example, what is the impact of irrigated agriculture on downwind rainfall? Global-scale models show that moisture recycling is an important source of water for inland regions around the world, but they do not...

Assessing the Impact of Storm Regime on Remotely-sensed Precipitation Extremes Across the Western Himalaya

Creator:: Stanton, Alan L.
Abstract:: Extreme, flood-producing precipitation events in mountains threaten human life and local and national economies. In the Himalayas, scarce meteorological data historically limited understanding of the underlying processes driving extreme events. However, the capacity to observe, measure and quantify precipitation on regional scales has increased tremendously over the last three decades...

Spatial variability of dust deposition in the Luquillo Mountains, Puerto Rico

Creator:: McClintock, Matthew
Abstract:: Dust deposition on ecosystems with highly weathered soils may provide vital rock-derived nutrients that maintain ecosystem productivity. Because of the difficulties in measuring temporally and spatially heterogeneous dust deposition over ecologically meaningful timescales, evaluations of the spatial variability in dust deposition are extremely rare. In the Luquillo Mountains of Puerto...

Abstract:: The emission of sulfur oxides from anthropogenic sources represents a potential threat to terrestrial ecosystems. Sulfate, the most highly oxidized form of sulfur, is the most common form of inorganic sulfur in most soil environments. The sorption of sulfate may influence the alkalinity of the soil solution and as a...
