Fisheries Research Report No. 111 - Sea Temperature Variability Off Western Australia 1990 To 1994, Alan Pearce, Mark Rossbach, Marion Tait, Rhys Brown

Fisheries Research Reports

Analysis of temperature data from coastal waters between Shark Bay and Cape Mentelle has shown the main features of temporal and spatial variability in temperature along the Western Australian coastline. Three distinct periods of variability emerge: the annual cycle (peak temperatures generally in January-February and troughs in July-August), a few-day (weatherrelated) cycle, and the diurnal pattern.

Summer temperatures range from 24° C (South Passage) to 19° C (Cape Mentelle), and winter temperatures from 21° C (South Passage) to 16° C (Marmion). Mean annual temperature ranges (winter minimum to summer maximum) are between 3° C (South Passage) and 7° C (Alkimos), …

Bulletin 4329 - Environmental Hazards Of Farming In Western Australia, Greg Hamilton, Ian Foster, Philip M. Goulding

Bulletins 4000 -

This Bulletin is one of a series on crop establishment practices which minimise soil disturbance and improve stubble retention. In partnership with primary producers, Agriculture Western Australia 1s focussed on improved and profitable farming which conserves or improves the quality of the State's soil resources.

Agricultural land in Western Australia is naturally fragile and susceptible to degradation. Salinity and wind erosion are the most visible and significant forms of degradation, but all forms are present over large areas of agricultural land (House of Representatives Enquiry into Land Degradation in Western Australia, 1988).

The fragility of Western Australia's soils has been …

Global Climate Change Response Program, Water Yield In Semiarid Environment Under Projected Climate Change, United States Department Of The Interior

Water

This paper presents the practical application of a distributed parameter climate vegetation hydrologic model (CVHM) and its ability to simulate hydrologic response under existing conditions and under assumed CO₂-induced climate and vegetation change. Applying the model to the Weber River basin provided a basis for determining the impacts of climate change on the hydrologic response. By using a "what if" scenario this model included the changes in plant transpiration rates and in vegetation cover under a CO₂-altered climate change and the effects of these changes on water yield.

Miscellaneous Publication 10/94 - The Climate And Soils Of South-Western Australia In Relation To Vine Growing, J. S. Gladstones

Viticulture research reports

The vine industry in Western Australia is at present located mainly in the Swan Valley, some 15 miles inland from Perth. It produces currants for export, wine grapes, and table grapes for both local and export markets, in approximately that order of importance.

Climatically, the Swan Valley is well suited to vine fruit production. With an annual rainfall of about 34 inches, it has a mild, wet, almost frost-free winter, and a warm, dry summer. Olmo (1956) concluded that the Swan was especially well suited to the production of currants, table grapes and sweet dessert wines. However, he considered that …

Impacts Of Projected Climate Change On Urban Water Use, United States Department Of The Interior, Bureau Of Reclamation

Water

Urban water use, particularly outdoor use, responds to changes in temperature, precipitation, and other climatic parameters. This study significantly improved the capacity of an existing regional water demand model to estimate the response of both residential and commercial-industrial water demand to changes in climatic parameters. The resulting functional relationships derived from historic time-series climatic and water use data were applied to global climate scenarios for the four Wasatch Front counties of Utah.

The Importance Of Understanding Climate And The Use Of Climate Information, Stanley A. Changnon

Journal of the Minnesota Academy of Science

In this paper, the interrelated issues of understanding climate and its importance are addressed through consideration of three factors. Considered first are the general views of climate, as seen by three principal groups who deal with climatic conditions; the public, the weather-sensitive sectors, and the scientific community. The second consideration is how the atmospheric sciences community and climatologists specifically, have helped society function. Finally, activities and knowledge of climate which are changing over time, are assessed. I want to stress these are views· developed over 43 years as an atmospheric scientist. I have had the privilege of conducting a wide …

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 …

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 …

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 …

Development And Evaluation Of Tracer Particles For Use In Microzooplankton Herbivory Studies, Mary Putt

OES Faculty Publications

Two methods of preparing algae for use as tracer particles in single species measurements of microzooplankton herbivory were evaluated. Algae were either heat-killed and labelled with 5-(4,6-dichlorotriazin-2-yl amino fluorescein) (DTAF) (Rublee & Gallegos 1989; Mar, Ecol. Prog. Ser. 51: 221-227) or stained with hydroethidine (HYD). Both DTAF and HYD-stained algae were readily visible within the digestive vacuoles of most microzooplankton collected in estuarine and coastal waters of Massachusetts (USA) and preserved with Lugol's iodine. However, DTAF was ineffective at staining several chromophytic algae and the heat-kill process reduced cell volume by ≥ 50% in several of the algae which were …

Long-Term Reconstruction And Analysis Of White River Streamflow, M. K. Cleaveland, D. W. Stahle, J. G. Hehr

Arkansas Water Resources Center Technical Reports

A 281-year reconstruction of White River annual runoff at Clarendon, Arkansas, was developed from a regional average of nine Oklahoma, Missouri, and Arkansas tree-ring chronologies (six post oak, Quercus stellata, and three baldcypress, Taxodium distichum). Inhomogeneity of the gaged series was detected with both double mass analysis (using state average total annual Arkansas precipitation) and regression (using the regional tree-ring average). Simple regression calibrated the homogeneous runoff data with the average ring width data from 1930 to 1980. Comparing the reconstruction with independent data verified the regression model. Variance of the reconstruction increases significantly during the 20th century, a change …
