Matt's World Of Weather: Last of the Folklores

Hope You Got Something Out of It
I just wanted to take a quick second and thank you for participating in the first ever World of Weather "Theme Month". Overall, it was a great success and I hope you were able to gain a little insight on the science behind some of these folklores. That being said, in the future I am planning on dedicating a month to weather mysteries (contrails, ball lightning, Northern name it). In fact, if you already have some suggestions, feel free to comment on the story.

Now then, where were we...

Staying Hydrated
In the video portion of this week's World of Weather I mentioned the importance of water when referring to nighttime temperatures. Without it in the atmosphere, temperatures tend to fall like a skydiving elephant. When forecasting the weather, water takes on so many different properties that it's location, amount and physical state is often the crutch of every forecast. Not only will it make or break a 7 day outlook, but at the very basic level, we need it to live.

So the next time we add a little Cherry Cool-Aid to our dihydrogen oxide (H20) friend, think about some of these interesting characteristics that make up a small drop of "Adam's Ale":

-Obviously we've observed it in all three physical states (Snow, Rain and Fog), BUT, water is the only natural substance that can actually do this at "normal" earth temperatures. Every other natural substance needs an extreme temperature to meet the three physical states.

-Speaking of physical states, ice is less dense than water and thus floats. Sure that doesn't sound like much, but without this unusual property, lakes would freeze from the bottom up. This would complicate things significantly for our friends with gills

-Sound can move through water at nearly 3,500 miles per hour. For comprehension sake, an Irishman snorkeling off his coast in search of a four leaf clover would hear a loud noise produced underwater at Cape Hatteras in less than an hour (Cape Hatteras to Ireland is ~3370 miles).

Forecasting Note
A dehydrated sky, despite strong lift in the atmosphere, won't produce rain/snow/sleet.
