About the research
Over the last several decades, Minnesota’s winters have gotten warmer. In fact, the winters have warmed significantly faster than the summers. Such a trend is forecasted to continue into the foreseeable future. It is possible that this warming trend has increased the length of time spent around the freezing point (32°F), thus also increasing the average number of freeze-thaw events. However, it is also possible that this warming trend has resulted in no change in the number of freeze-thaw events. The proposed research has two primary objectives: (1) to attempt to quantify the number of freeze-thaw events daily, monthly, and annually from historical temperature records, freeze gauges, and other data; and (2) to attempt to collect ground/pavement temperature and study its correlation with air temperature during freeze-thaw events. To achieve these objectives, a two-phase research approach has been developed.
