Soil temperature directly responds to atmospheric temperature, although a variety of climatic and soil variables influence actual soil temperature. Whereas most relationships about soil temperature have been established at a point, this research assesses the relationships of soil temperature at three depths to a variety of climatic variables along a 200-km transect in central Oklahoma. Our observations support known conclusions that soil temperatures increased at all depths from east to west. Sub-surface temperature changes lagged one week behind atmospheric conditions. A precipitation event of 2.0 cm is required to have a significant impact on soil temperature at all depths. The location of the field site along the transect and the week of data collection explained significant amounts of soil temperature variability at each of the three depths evaluated. Elevation, soil texture, and antecedent environmental conditions prior to data collection were combined with spatial (site location) and temporal (sample week) variables to explain additional levels of soil temperature variability.
