Decreasing diurnal temperature range in the United States and Canada from 1941 through 1980
An appreciable number of nonurban stations in the United States and Canada have been identified with statisically signficant (at the 90% level) decreasing trends in the monthly mean diurnal temperature range between 1941--80. The percentage of stations in the network showing the decrease is higher than expected due to change throughout the year, with a maximum reached during late summer and early autumn and a minimum in December. Monte Carlo test indicate that during five months the field significance of the decreasing range is above is due to chance. In contrast, trends of increasing or decreasing monthly mean maximum or minimum temperatures have at most only two months with field significance at or above the 90% level. This is related to the tendency toward increasing temperture in the western portions of North America and decreasing temperature in the east.
