SEASONAL TEMPERATURE AND PRECIPITATION TRENDS AT FIVE MINNESOTA STATIONS

Abstract

Seasonal and annual temperature and precipitation changes at five Minnesota stations considered as climatological reference stations were calculated during several extended time periods. For 1900?58 winter temperatures increased most and a decreasing fall precipitation trend was found. With a longer period, initial date earlier than 1900, fall temperature increases nearly equalled those of winter. A declining, though nonsignificant, seasonal and annual precipitation trend was noted in a majority of the station records.
