PAGE TWELVE Comfort Chant Humidity, Heat Cause Discomfort By JOEL MYERS Collegian Weather Expert isn't the heat it's the humidity." Many people ar e heard quoting this phrase during the summer months in an attempt to explain their discomfort which is due to the oppressive weather. The actual cause of their dis comfoi t, however, is a combina tion of these two weather factors —heat and humidity. Since the knowledge of either the temperature or humidity does not always give an appro- priate measurement of comfort, a scale based on some type of combination of these two factors will give some idea of human comfort. I have developed the following table to allow the public to easily compute body comfort. Before describing this table, it will be necessary to explain a basic principle upon which it is founded, If you wet one hand and leave the other one dry and then wave both hands in the air, an apparent difference in tempera ture is noted between the two hands. The wet one feels cooler because the evaporation is a cool ing moms. This is the principle upon which the wet bulb ther mometer is based. It is merely a normal outdoor thermometer that has a wick placed around the bulb with water on the wick. In other words, two thermo meters are needed to make use of the comfort scale—a wet bulb and a regular one. Since water evaporates from the wet bulb at a rate that varies with the amount of moisture in the air, a large deviation between the air temperature and the wet bulb reading indicates dry air. That is, the lower the relative humidity, the faster the water will evaporate from the wet bulb thermometer, and hence the greater the difference between the actual temperature and the wet bulb temperature. To make use of the comfort scale perform the following simple calculation: Talte the wet bulb reading and divide it by the actual tempera ture and then multiply by 100. Wet bulb Temperature To this number add or subtract the amount indicated below ac cording to the air temperature. AIR TEMPERATURE Table 1 40 to 45 (subtract 75) 46 to 55 (subtract 60) 56 to 65 (subtract 45) 66 to 75 (subtract 30) 76 to 85 (subtract 15) 96 to 95 (no change) 96 to 105 (add 15) The number that is remaining I have named the COMFORT NUMBER and is simply com pared to table 2 and body com fort is found.

Bureau has the means of predict ing both temperature and wet' bulb readings with a reasonable degree of accuracy. By plugging' the predicted high temperature' and high wet bulb reading into the above formula, the maximum discomfort for that day may be computed in advance. It must be noted that the above scale will be accurate so long as no precipitation is fall ing and the wind is less than 25 miles per hour.
