They are calculated usingclimate observations collected at local weather stations across the countryand are corrected for bad or missing values and any changes to the weather station over time before becoming part of the climate record. Climate Normals were not developed to track or document climate change, but instead to characterize the current climate. While annual normals changes were generally consistent, the single months showed pattern shifts that indicate a relationship to repeated preference of certain upper air wind patterns and storm tracks that shifted north or south with the seasons. Of the stations reporting precipitation, more than 1,600 have adequate observations to report snowfall and snow depth normals. Applequist, S., A. Arguez, I. Durre, M. F. Squires, R. S. Vose, and X. Yin, 2012: 19812010 U.S. Past Events Changes during the core months of each season (January, April, July, and October) can be representative of broader differences between different normals iterations. 2012; Arguez et al.
