North Dakota Temperature Change

Global temperature is increasing. Global temperature is rising as fast in the past decade as in the prior two decades (Hansen, et al. 2010). Global ocean and surface temperature change is not only a worldwide problem but also a regional issue. The effects of surface temperature change in North Dakota have already been observed including precipitation pattern change, as well as, shorter, milder winters. The focus of this study is to investigate surface temperature change in the state of North Dakota. This research included 18 weather stations across the state which were divided into six different climate areas. The six areas are northwest, north-central, northeast, southwest, south-central, and southeast. The study focused on one weather station from each climate area by comparing mean monthly high and mean monthly low temperature change in two climate periods. Climate period temperature trends also were examined. Climate data for the two periods came from the United States Historical Climatology Network and the Grand Forks National Weather Service: 1) 1971-1980; and, 2) 2001-2010. The results from these two climate periods included temperature graphs and statistical analyses. Based on temperature graphs and statistics (t-test), the results show similar changes in North Dakota temperature with subtle important differences based on location. Wintertime temperatures tended to warm more than summertime temperatures. Trend patterns indicated subtle, yet similar, changes in temperatures across North Dakota.
