It can be challenging at times to go on television and repeat the same story. Usually during the summer we’re repeating “hazy, hot, and humid” over, and over, and over again; however, this summer, we may never see 100 degrees with the green vegetation, and the abundance of gulf moisture.
Evapotranspiration is a big part of the water cycle. Plants and trees help to continually hydrate the atmosphere during the spring and summer months; moreover, rich green plants contribute to evaporation, which in turn has a cooling effect on the surrounding air. Think about when you sweat on a summer day. Your evaporate water from your body, which helps to cool your body. Trees are cooling the air around them.
The U.S. Forestry service says that a mature 40 ft tree can reduce the surrounding air temperature by transpiring some 40 gallons of water each day.
Last year we hit 100 degrees in the middle of July in Fort Smith. Interestingly enough, both June and July were completely dry at the Fort Smith Airport. The vegetation was dead, which helped contribute to the hot temperatures.
If the vegetation remains green it wouldn’t surprise me to see the area dodge the dreaded 100 degree mark! I hope I’m right!
