Frost Injury To Cereals In W.A, M W. Perry, A. G. P. Brown

Journal of the Department of Agriculture, Western Australia, Series 4

Late spring frosts commonly reduce yields and affect the quality of grain in wheat crops, especially in the southern, eastern and north-eastern districts. The damage is usually localised on individual farms, but is sometimes widespread.

Barley, and oats to a lesser extent, are also affected. Average losses of wheat in Western Australia have been estimated at 3 to 5 per cent, per year, or about 2 million bushels on current production figures.

Role Of Transition Metals In Nitrite Decomposition In Soil, J. S. Bajwa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Iron and copper increased the decomposition of nitrite significantly during the first two hours of reaction when 150 parts per million (ppm) of nitrite and nitrogen was added to an acidic soil. Manganese was found to have a slight effect. There was no additional effect of the added metals after two hours reaction time.

The higher concentration of metals was not effective in catalyzing the decomposition of the added nitrite in nitrogen. All the added nitrite nitrogen was not recovered and the deficit could be due to the formation of nitrogen gas.

A Functional Analysis Of The Naval Weather Service System, Charles P. Pfarrer Jr.

Marine Affairs Theses and Major Papers

The purpose of this paper is to analyze the Naval Weather Service system by defining its functions; for the available literature does not convey the concept of interacting elements contributing to the operation of the larger whole. This paper concentrates on articulating the contributions of the related actions to the Naval Weather Service system. The aim is for clarity of exposition. The purpose is to get across the big picture. Int introspective format ensues formally from the rational foundations of the conceptual mode of inquiry. This paper addresses the Naval Weather Service system and not the scientific and technological process …

Annual Precipitation Regime Of Minnesota, Richard H. Skaggs

Journal of the Minnesota Academy of Science

Eigenvalues and eigenvectors computed on 30-year normals indicate an unusually high spatial homogeneity of annual precipitation curve shape in Minnesota. The generalized shape accounts for about 99 per cent of the observed variance and meshes well with the overall pattern of the central United States. Interesting deviations do occur, however. These deviations suggest fundamental questions about precipitation-causing processes which should be investigated in the future.

The Growing Season, Department Of Agriculture, Western Australia, Bureau Of Meteorology

Journal of the Department of Agriculture, Western Australia, Series 4

IN AUSTRALIA the seasons of summer, autumn, winter and spring do not have the importance that they have in the Old World, and though summer and winter weather are quite different, there is not the obvious difference in autumn and spring conditions that there is in the colder countries.

This is largely due to the difference in vegetation and in its life cycle in the different places.

Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling

KWRRI Research Reports

Part I

A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.

Part II

Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:

1. Transfer between the plant leaf and the canopy …

Likelihood Of Drought Years In South-Western Australia : How Often Can Droughts Such As That Of 1969 Be Expected In Western Australia's Farming Areas?, Eugene Adsil Fitzpatrick

Journal of the Department of Agriculture, Western Australia, Series 4

Because of the serious consequences of drought to individual farmers and to Western Australia's economy, it is worth making an early appraisal of the 1969 rainfall conditions that led to the State's most recent drought in an attempt to estimate how often such seasons might be expected in the agricultural areas.

Dry Season In The Eastern And North-Eastern Wheatbelt, George Henry Burvill

Journal of the Department of Agriculture, Western Australia, Series 4

The drought of 1969 ended an 11-year run of good seasons in the eastern and north-eastern wheatbelt. Good years usually have above average rainfall; wheat yields and pasture growth are greatly reduced if rains are well below average. Eighty years records show that half the years must be expected to be below average and about one-third could be well below. This area produces one-third of the State's wheat and has 9 per cent, of its sheep.

Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James

KWRRI Research Reports

The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.

Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event …

A Synoptic Air Mass Climatology Of The Eastern United States, Robert I. Wittick

Masters Theses

Chapter I

Introduction

Orientation and Objective

The concept of the air mass was developed by a group of Norwegian meteorologists during World War I. An air mass, they said, was a body of air which was horizontally homogeneous with respect to temperature and humidity. These bodies of air were classified according to their place of origin since the basic character of an air mass is similar to that of its source region.

Since 1932 when the first air mass climatology was written by Dinies¹, the meteorological and geographical journals have published many studies of air mass movements and …

Summer And Autumn Rainfall In Relation To Epidemics Of Wheat Stem Rust In Western Australia, W A. Shipton

Journal of the Department of Agriculture, Western Australia, Series 4

High summer and autumn rainfalls, followed by rust infection of volunteer plants and favourable conditions during late winter and spring, lead to rust epidemics.

WIDESPREAD outbreaks of wheat stem rust are rare in Western Australia.

Frost Injury Of Wheat, S C. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

Late spring frosts commonly reduce yields and affect the quality of grain in many wheat crops- especially throughout the southern, eastern and north-eastern districts.

The damage is usually localised on individual farms, but occasionally widespread damage occurs in the south of the State.

Thunderstorms And Tornadoes Of February 1, 1955, Jean T. Lee

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

The purpose of this paper is to describe and illustrate some of the features that are of particular interest in the forecasting of one of the most death-dealing series of convective storms of the 1950s that occurred during the afternoon and evening of February 1, 1955. This series of severe storms included tornadoes, destructive winds, hail, and heavy rain that first struck near Marianata, Arkansas, then roared through Commerce Landing, Mississippi and northern Mississippi. then moved on to near Huntsville, Alabama.

Includes features at the surface, at 850 mb, 700 mb, and 500 mb, and upper air conditions, along with …
