Climate Trends In Iowa, Richard E. Carlson

Journal of the Iowa Academy of Science: JIAS

Long-term trends for various weather elements are presented for the period 1900-1988. Summer and winter season, and annual air temperature patterns are statistically weak because of large inrerannual variability, but trends are evident. There was a general warming from 1900 until the 40's, with a leveling or slight cooling following. Since the mid-70's, a warming trend seems to be taking place, but this cannot be confirmed. Spring season air temperatures showed no trend except that the most recent 4 years (1985-1988) were decidedly warmer than normal. Winter season air temperatures showed a change in trend in the 30's, but the …

Climate Change And The Potential Impact On The Soil Resource, J. L. Hatfield

Journal of the Iowa Academy of Science: JIAS

Climatic change will lead to changes in the carbon dioxide C0_2, temperature, and precipitation. There have been many predictions of the effect of climatic change on plant growth but none on the soil parameters or water use. To fully understand the implications on soil management from climate change the expected changes in soil temperature, water use, and water and nutrient use efficiency need quantification.

Glaciochemical Investigations As A Tool In The Historical Delineation Of The Acid Precipitation Problem, William B. Lyons, Paul Andrew Mayewski

Earth Science Faculty Scholarship

Precipitation in the Northern Hemisphere has been recently recognized to have hydrogen ion concentrations 10 to 100 times higher than expected for natural precipitation (Likens and Bormann 1974, Cogbill and Likens 1974, Lewis and Grant 1980). However, controversy has arisen regarding the nature of the acidity of the precipitation sampled and whether, indeed, the pH of North American precipitation has increased over time (Miller and Everett 1979, Lerman 1979, Stensland 1980, Sequeria 1981, Carlson and Rodhe 1982). In most locations pH records have been constructed rather imperfectly due to differences in sampling, handling, and analytical procedures used (Galloway and Likens …

Temperature Conditions At Orono, Maine, Ernest Claude Drew

Electronic Theses and Dissertations

This thesis is an outgrowth of a much larger piece of work which the Department of Physics, thru its instructors and major students, has undertaken to complete. The task referred to, is the compilation, arrangement, and summarizing of the various meteorological records taken at the University of Maine for the past forty-four years. These records were begun in the above department by Dr. M. C. Fernald in the year 1869 and were continued by him until 1893. The work was then transferred to the Experiment Station, where observations were made under the direction of Doctors W. H. Jordan and C. …
