Education & Reference - 29 October 2006

Hey can someone explain this to me?
The decrease in temperature coupled with the low density of the air in the mesosphere (about 1 gm-3; at the stratopause, or a thousandth of the density at sea-level, to 100 times less at the mesopause) means that the mesosphere includes both turbulence and atmospheric waves which have a wide range of spatial and temporal scales. Such motions are important not only because of the mixing of chemicals that occur as a result, but also because the mesosphere is the region of the atmosphere where spacecraft on re-entry start to feel the background wind structure, rather than just aerodynamic drag. Some of the small-scale waves drive an average seasonal flow upwards from the lower summer polar mesosphere across the equator and down deep into the winter polar stratosphere.

I am having a hard time comprehending it, thank you!

I am so sick of them spelling it loose.
It is "they will lose the game" NOT "they will loose the game."

What I mean is would it help your grade more if like tests and hw's were a specific percentage of your grade or if it was just by points. But then if it were just by points then every point would matter but then weighted percentages would lower the grade a lot if the tests were worth a lot...so which one would be the best for your grade?or does it matter?

My friends and family are very important to me, and having a small piece of them with me-- even if just in a photograph or letter-- is soothing.
