摘要:

ABSTRACTA substantial percentage of days with below normal temperatures in central Illinois during May and June (1956‐1965) appear to be associated with polar air masses which traverse the Hudson Bay area before entering the Midwest. January departures, in contrast, are related to polar air masses that enter the United States near the Mackenzie River in western Canada. The general influences of the Hudson Bay area on climate are discusse

摘要:

ABSTRACTData provided by the Australian Commonwealth Bureaus of Meteorology and Mineral Resources are used in this water budget study of the Queanbeyan River watershed. Air and soil temperatures show close correlation from month to month during the five‐year period. A close parallel also exists for the air temperature values and the seasonal variations in the Nett‐Moisture (rainfall minus evaporation) plots. Ground‐water levels appear to be influenced by drought periods and by under groundwater storage conditions such as “nick‐points” in the sub‐surface migration conditions. The groundwater levels were unusually high early in the drought year of 1964‐65. The annual rainfall totals for 1962, 1963, and 1966 were all exceeded by the evaporation totals. In 1964 and in 1965 (the drought year) the evaporation total exceeded the rainfall total. The minimum annual water discharge values for the Queanbeyan River ranged from 4.9″ in 196

摘要:

ABSTRACTMean temperature is employed universally as an index to the energy status of the environment, and to indicate probable reaction rates of physical and biological processes in nature. A versatile chemical method of temperature integration, based on the temperature dependence of sucrose hydrolysis, has been tested in central Pennsylvania. The chemical technique (after Pallmann) permits economical mass sampling of air, water, and soil temperatures in situations where conventional methods are too expensive or otherwise unsatisfactory. Short‐wave radiation effects are negligible since the sensing elements are transparent. Repeatability is excellent: in field tests duplicate sensors yield the same mean temperature ± 0.02°C. Non‐linearity of sensor response has been resolved, and the data can be related directly to measurements obtained in standard climatological networks. The technique can be used to good advantage in a variety of hydrological investigations, including evaporation, consumptive‐use, and them pollution

摘要:

ABSTRACTDaily, monthly, and yearly summaries of streamflow and sediment transport are computed from continuous gage height records and discrete measurements of sediment concentration and discharge rate. The system includes computer computation of discharge measurement notes and an accuracy check of gage height and time input data. Maximum volumes of runoff for selected time intervals up to eight days and flow duration data can also be compiled. Electronic data processing equipment including a chart reader, card punch, computers, and card sorter are used. The system software includes 12 Fortran programs.
