	Wikipedia give a good explanation of this. Google them __________________ Life is not a journey to the grave with the intention of arriving in a pretty, pristine body but rather to come sliding in sideways, all used up and exclaiming, "Wow, what a ride!"

	It is a indication of humidity. The wet bulb is surrounded by cloth that is moistened with water while the dry bulb is just plain. More humid air will cause slower evaporation and therefore less temperature drop. In dry weather the moisture on the cloth evaporates faster and causes a bigger temperature difference. __________________ Never do today what you can put of until tomorrow - Student motto

	Thanks Hendrik, I gave you a GA. I had not heard the term before. I do wish, however, that people asking questions would try to word them in some semblance of sensability. A few more details etc. __________________ They that do not learn from history and apply those lessons to the present are bound to repeat its failures.

	I gave you a GA too, but mine was for not telling the OP about sling psychrometers. He'd only hurt himself. __________________ "Well, I've wrestled with reality for 35 years, Doctor, and I'm happy to state I finally won out over it." Elwood P. Dowd

	dry bulb temp. is measured by by the direct thermometer in the atmosphere and wet bulb is measured by covering the wet cloth around the bulb of the thermometer.
