RELATIONSHIP OF HOURLY DURATIONS TO THE DAILY MAXIMUM TEMPERATURE.

摘要

Durations of temperatures within 10 F degrees of the maximum for 365hot summer days from the upper midwestern United States are compared with those at Yuma,Arizona,and found to be similar. On only 30percent of the observed days does the daily maximum temperature as recorded on a maximum thermometer appear in the hourly records. The hourly maximum temperature rarely persists for longer than 3hours,while at 10 F degrees below the maximum,the average duration is approximately 10hours. (Author)
