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 ...

Abstract: The increased interest and application of heating degree days (HDD) and growing degree days (GDD) prompted this study into the effect of different observation times upon the mean daily temperature. The study was based upon ...

Abstract: This study is based upon net radiation measurements made with a Suomi-type ventilated net radiometer. The average annual net radiation was 36,247 ly for the study period 1 April 1964?31 March 1967. April?October showed ...

Abstract: Incoming and reflected hemispheric radiation were measured at St. Paul over four different surfaces (sod, alfalfa, soybeans, and green peas) for a combined total of 5778 days between 21 November 1969?31 December 1985. ...

Abstract: Mean and median daily albedos of the November-April period are presented for a nonforested station in the North Central region of the United States where frozen soil and persistent snow cover are common winter features. ...

Abstract: Freeze-thaw frequencies calculated by eight different counting methods were compared using daily maximum and minimum temperatures from eight north-central United States National Weather Service (NWS) stations. These ...

Abstract: This climatological study reports on the potential for atmospheric diffusion at Minneapolis?St. Paul, Minnesota, cities located in the heart of the North American continent. As such, the results can be considered typical ...
