The article reports on the research conducted by Richard L. Phipps and Clark P. Baker of the U.S. Geological Survey on the significance of measuring soil moisture, rainfall, temperature and microchanges in different habitats in Arlington, Virginia. Researchers discovered that data gathering problem on habitats including hilltop and stream valley can be solved by using an automated system that records data on punched paper tape wherein it will then be transcribed to magnetic tape for high speed computer use. Such kind of technique is commonly employed in ecological and agricultural field studies.

Fourier and spectral analysis of rainfall records at 163 South African stations over the period 1910-1969, and at thirty-nine stations from 1880–1969, shows that cyclical fluctuations with periods of about 18–20, 13–15, 10, 4.5, 3.5, 2.8, and 2.3 years account for much of the observed rainfall variance over the country. These fluctuations exhibit distinctive regional distributions that appear to have changed little over the last century. [ABSTRACT FROM AUTHOR]

Focuses on the nature and origin of the Canadian Dry Belt, dry regions in the Great Plains of North America. Measurement of annual precipitation; Variability of precipitation; Classification of climate.

The article presents a discussion of the environmental factors which affect ion transport in a Douglas-Fir forest soil in Western Washington. The article implies that a field study was conducted on a Pleistocene glacial-outwash soil to be able to produce conclusions. Methods of the study include the automated tension-lysimeter system applied to soil solutions. These solutions were passed through flow-cells where electrical conductivity, acidity, and flow-rates were recorded. An investigation of rainfall, precipitation, and temperature was also conducted. Results of the study show that forest floor was the most biologically active component of the soil system.

The article reports on the availability and circulation of chemical nutrients, as well as the mineral and organic soils of Signy Island, one of the smaller members of the South Orkney group. Experiments suggested that there are three sources of nutrient supply on Signy Island, Rock breakdown, directly marine, and indirectly marine. Also, in oceanic areas like the Antarctic, where industrial fumes and soil dust are not significant, the sea contributes almost all the salt constituents of precipitation. It was concluded that the pattern of nutrient supply on Signy Island holds most for the perimeter zone of the Antarctic.

The article presents a discussion about climatic classification based for East African biology. The article provides a brief introduction and knowledge about the relevant characteristics of East Africa. It explores the classifications of climate using Köppen system and derivatives, functions of rainfall, evaporation, and temperature, and months with a defined climatic ratios. The article is also supplemented with details regarding the importance of mist and cloud, meteorology, and precipitation.

This article presents a study regarding the forests of the western portion of the Caucasus range. The very fertile stretch of land of Colchis lies on the eastern shores of the Black Sea. The parts of Asia and Europe which lie around the high ridge of the Caucasus are mostly dry grasslands and dry deserts. The southwestern part is thickly wooded all over and the water-laden southerly winds which beat against the high walls of the Caucasus bring great quantities of atmospheric moisture and rain to Colchis.

Describes the climate of New Zealand. Contrasts in rainfall totals; Division of the climate; Climatic boundaries.

Focuses on the applicability of harmonic analysis on the study of precipitation patterns in the United States. Description of certain features of the precipitation climatology; Manner of transition from one rainfall type to another; Variations superimposed on the annual or semiannual terms.

Presents a comparative study of dry western littorals. Speculation about the causes for the extreme aridity; Theoretical knowledge of the atmospheric processes at work; Correlation between spatial variations of sea temperature and precipitation averages.

The article focuses on the climate of the Argentine Republic according to a new classification. The purpose of a climatic classification is to characterize climatic regions in terms of those principal elements, such as temperature and precipitation, which are the most decisive in the determination of the landscape of the earth's surface. Moreover, it attempts to develop the similarities which these great climatic units bear to each other and their relation to their principal causes, the effect of latitude and of atmospheric and oceanic circulation, in opposition to geographic accidents.

Presents a revised map of the climates of China, which follows a slightly modified Koppen classification. Temperature and precipitation records; Major climatic realms; Dry climates of Northeast China.

The article discusses the relationships between rainfall and evapotranspiration of moisture. Transpiration of water that enters through the plant roots; Process involved in evapotranspiration; Concurrence between the march of precipitation through the year and the changing demands for water.
