Atmospheric Response To 1988 Drought Conditions And Future Climate Implications, Michael D. Mccorcle
Atmospheric Response To 1988 Drought Conditions And Future Climate Implications, Michael D. Mccorcle
Journal of the Iowa Academy of Science: JIAS
Plentiful precipitation in the central United States is one of the basic components of the successful agricultural industry in the Corn Belt. A combination of moisture, wind, and topographic factors creates an ideal condition for rainfall over most of the region during the late spring and early summer. In 1988, many ingredients necessary for wet weather were absent. The region experienced a drought unequalled since the 1930's. The drought of 1988 demonstrated chat the symptom of drought, namely, dry soils, can exacerbate and even perpetuate drought conditions by decreasing available moisture, altering circulation patterns vital to storm development, and increasing …

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 C02, 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.

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 …
