A Comparison of Methods for Computing Daily Mean Values of Dry Bulb Temperature, Dew Point, and Relative Humidity

Abstract

Ihy bulb temperature: synoptic mean us. 24-hr. 'mean. m e a n and standard deviation of daily departures. 5 years of record, AvPrage departure of mean of 4 synoptic observations jrom 24-hr. o v. The daily Inems were rounded to one clecinlal to tletermine the daily differences which were then rourltled to whole numbers. These daily differences (Id, 2d, and 3c) for each rrlont'll st each stat'ion for the five years were then accumulated in a frequency table. The class intervals were 1' F. for dry bulb and dew point temperatures and 1 per

Means and Midranges of Relative Humidity

“…The most striking similarities between the regression lines in figures 1 The few exceptions to these trends usually occur in samples confined within small ranges. At Nantucket in July, the only example in which the regression line slopes downward, only one-tenth of the midrange values are below 70 percent relative humidity and none below 60 percent.…”
