Title: 3% Relative Humidly, 106 deg F in Phoenix
Post by: gdavis9999 on June 16, 2017, 03:10:26 PM

 :shock:

Just moved to Phoenix. I have never experienced 3% relative humidity before. The evaporative cooling is deceiving. You can get out of a pool or stand under misters and feel cold in heat over 100 degrees! The endothermic reaction absorbing so much heat from the liquid to vapor conversion is extreme.

My station is here https://www.wunderground.com/personal-weather-station/dashboard?ID=KAZSCOTT315#history
It will get up to 120 deg this coming week.
Crazy!



Regards, Greg

C'mon down to Tucson, we've been at 1% ad nauseam...
Yes getting out of pool now is an "eye opening" experience, especially if there's some wind.  :-)

Oh yes! I totally forgot to add that evaporative cooling is certainly higher when its windy!

I wonder how many gallons/second are being evaporated from the lake and fountain in Fountain City when the geyser is on for the 15 minutes every hour?

Does any water actually re-enter the lake when it is on during these kind of conditions with low humidity, high temperature and wind?

I have been curious about that since we saw it during the winter one year.

And I think the dept of interior must have done some calculations on the evaporation losses on the big Colorado River reservoirs during this wx, also.  Must be a lot of water
