We went for a walk down to the beach with teas. It was quite cold. There was frost on the grass, which was kinda weird since it didn’t seem that warm today.
I wondered about the frost for a while, and then thought about dew for a bit. Came home and looked at the weather info for Toronto, and saw that the Dewpoint is 7 degrees celcius. This led me to wondering what the hell dewpoint means, exactly, so I looked that up (but not in the encyclopedia, because I don’t have one.) This is what I learned from this USA Today site:
Dewpoint: the temperature air would have to be cooled to in order for saturation to occur. The dewpoint temperature assumes there is no change in air pressure or moisture content of the air.
So I kind of half understand now. Maybe if I feel like really finding out I’ll ask Adam, he’s the one with the physics hobby.
Also, I am reading and looking at pictures on this site.
This rambly and meaningless lj entry brought to you by a walk on the beach.
