Probable Glacial Climatic Conditions In Source Areas During Deposition Of Parts Of The Ash Hollow Formation, Ogallala Group (Late Tertiary), Of Western Nebraska, Patricia E. Helland, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Evidence of the climatic conditions in the mountain sediment source areas for the late Tertiary Ash Hollow Formation of the Ogallala Group in western Nebraska has been sought in an SEM (scanning electron microscope) study of surface features on detrital quartz grains from these deposits. The following lines of indirect evidence raised the possibility of glacial conditions: uplift of up to 3500 m in the source areas, paleohydrologic parameters indicative of a transport system analogous to the modern North Saskatchewan River, and possible cold climate surface features on cobbles from the deposits. SEM analysis shows that five of the nine …

Effect Of Wind Changes During The Last Glacial Maximum On The Circulation In The Southern Ocean, John M. Klinck, David A. Smith

CCPO Publications

Present-day surface wind stress climatology is manipulated to simulate wind conditions during the last glacial maximum. These estimated wind fields force a one-layer, wind-driven numerical model of the southern ocean to determine if a change in the strength of the surface wind stress can shift the location of the Antarctic Polar Front, which is part of the Antarctic Circumpolar Current. A change in the forcing by a factor of 0.5-2.0 results in a change in the speed of the flow by an identical factor with no change in position. However, if the present-day wind climatology is shifted meridionally there is …

The Potential Effects Of Climate Change On Summer Season Dairy Cattle Milk Production And Reproduction, Peggy L. Klinedinst, Donald A. Wilhite, G. Leroy Hahn, Kenneth G. Hubbard

National Drought Mitigation Center: Faculty Publications

The potential direct effects of possible global warming on summer season dairy production and re-production were evaluated for the United States and Europe. Algorithms used for milk production and conception rate were previously developed and validated. Three widely known global circulation models (GISS, GFDL, and UKMO) were used to represent possible scenarios of future climate. Milk production and conception rate declines were highest under the UKMO model scenario and lowest under the GISS model scenario. Predicted declines for the GCM scenarios are generally higher than either “l year in 10” probability-based declines or declines based on the abnormally hot summer …

Heat Storage And Transport Processes In The Tropical Atlantic Ocean, Andras Kapolnai

OES Theses and Dissertations

Heat storage and transport processes of the tropical Atlantic play an important role in the climate of three continents. The exploration of how the warm water mass maintenance in the equatorial basin depends on various external factors is therefore an important task. This study examines the annual cycle of the warm water mass formation and its transport in the equatorial Atlantic through the interaction of the atmospheric and oceanic boundary layers. Key features of the model are the sea level wind field, equatorial upwelling rate and escape transport of the formed warm water out of the equatorial basin.

The model …

Global Snow Cover Monitoring: An Update, David A. Robinson, Kenneth F. Dewey, Richard R. Heim Jr.

United States Department of Commerce: Staff Publications

Accurate monitoring of the large-scale dimensions of global snow cover is essential for understanding details of climate dynamics and climate change. Presently, such information is gathered individually from ground station networks and satellite platforms. Efforts are in progress to consolidate and analyze long-term station records from a number of countries. To gain truly global coverage, however, satellite-based monitoring techniques must be employed. A 27-year record of Northern Hemisphere continental snow cover produced by the United States National Oceanic and Atmospheric Administration (NOAA) is the longest such environmental record available. Records of Southern Hemisphere continental cover and snow on top of …

A Comparison Of Gulf Stream Sea Surface Height Fields Derived From Geosat Altimeter Data And Those Derived From Sea Surface Temperature Data, Tal Ezer, George L. Mellor, Dong-Shan Ko, Ziv Sirkes

CCPO Publications

Two types of satellite data, Geosat altimeter data and sea surface temperature data (SST), are compared and evaluated for their usefulness in assimilation into a numerical model of the Gulf Stream region. Synoptic sea surface height (SSH) fields are derived from the SST data in the following way: first three-dimensional temperature and salinity analysis fields are obtained through the Optimum Thermal Interpolation System (OTIS), and then SSH fields are calculated using a primitive equation, free-surface, numerical model running in a diagnostic mode. The aforementioned SSH fields are compared with SSH fields obtained from the Geosat altimeter data. Use of Geosat …

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …

Post-Shearing Losses Of Sheep Following Cyclonic Rains, M. Holm Glass, R. Jacob

Animal production and livestock published reports

Sudden unpredicted rainfall during summer has caused high mortality rates in newly shorn sheep on at least two previous occasions. These occurred at Darkan, Western Australia, in 1982 (Buckman 1982) and at Kybylolite in the south-east of South Australia in 1960 (Geytenbeek 1982).

Geytenbeek (1982) reported an average mortality of 8.3%, which was highest for sheep within five days of shearing. The mortality declined for animals shorn more than seven days before the rain.

Buckman (1982) reported an average mortality of 27.9% which was highest within 12 days of shearing. The losses related directly to the amount of rain received. …

Effect Of Aerosols On Climate Change, Haiyin Sun, Malay K. Mazumder

Journal of the Arkansas Academy of Science

A modified two-stream approximation is presented, which includes the effect of solar zenith angle and is applicable to study the effect of aerosols on both regional and global climate changes. More realistic results are derived. A reasonable critical value of 0.8 for aerosol single scattering albedo to determine whether the aerosols will heat or cool the climate is derived

Initial Climate Change Scenario For The Western United States, United States Department Of The Interior, Bureau Of Reclamation

Meterology

Observations of atmospheric carbon dioxide (CO₂) concentrations in recent decades have shown an accelerating upward trend due mainly to burning of fossil fuels. Physical considerations indicate that observed and projected increases in the concentrations of CO₂ and other greenhouse gases in the atmosphere will lead to significant global warming. Previous authors have followed both empirical and theoretical approaches to develop scenarios for changed climate conditions. The most common empirical approach is the use of analogs of global warming drawn from historical records and paleoclimates. The principal theoretical approach involves the interpretation of output for general circulation models …

Potential Impacts Of Biomass Production In The United States On Biological Diversity, James H. Cook, Jan Beyea, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Biomass could be a renewable source of energy and chemicals that would not add CO₂ to the atmosphere. It will become economically competitive as its cost decreases relative to energy costs, and biotechnology is expected to accelerate this trend by increasing biomass productivity. Pressure to slow global warming may also make biomass more attractive. Substantial dependence on biomass would entail massive changes in land use, risking serious reductions in biodiversity through destruction of habitat for native species. Forests could be managed and harvested more intensively, and virtually all arable land unsuitable for high-value agriculture or silviculture might be used …

Bulletin No 4174 - Tree Planting On Farms In High Rainfall Areas, Ken Angell

Bulletins 4000 -

Many of the techniques described in this Bulletin are applicable to broadacre farms. However, they are specifically directed to small rural properties in the high rainfall areas.

Trees can usually serve more than one purpose on small rural properties. They can be used as ornamentals, to provide shelter and shade, for erosion control, as a wildlife habitat, or for waterlogging and salinity control.

Photoacoustic Detection Of Carbonaceous Atmospheric Aerosols, Duane Jackson

Journal of the Arkansas Academy of Science

The role of carbonaceous aerosols in the atmosphere as a risk factor in climatic changes and health effects and state-of-the-art monitoring processes are briefly presented here. In particular, development of a photoacoustic technique for measuring the concentration of carbonaceous particles is discussed. The photoacoustic measurement is based upon detection of pressure waves generated by localized time-dependent heating of air inside the photoacoustic chamber. Heating of air inside the chamber is due to absorption of visible laser radiation by carbon particles present inside the chamber. The laser radiation is chopped, and the resultant pressure signal produced by subsequent heating and cooling …
