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!

Well, lets assume I'm dumb ok! and its the middle of the night, and I am just a kid, sheesh! Just explain it to me!
please?

Why can you people not understand that I am just some kid who is trying to do a project and needs help! I didn't pick the flippin project! Just break it down really simple

Unless you are an atmospheric scientist, the effects cited are not particularly important. The pressures are too low to have effect on weather or on surface phenomena.

just try and make it simple. Memorize what you can swallow. Memorize the definitions, look up the words you don't understand. It is basicly explaining what the mesophere is.
I assume you know that it is a part of the atmosphere? Memorize what part and the general location.
It has a low density which is a thousanth of the density that sea level is. The mesophere also has a low temperature. You combine those two elements and it creates turbulence and atmospheric waves (no idea what those are, use google to look it up) These wasves and turbulance vary greatly in their location in space and their timing (irregular)
I don't really understand the chemical mixing.
The decrease in temp and low density in the mesospher can cause spacecraft difficulty upon reentry to the earth's atmosphere.
Some small waves caused by the phenomenon can cause seasonal summer south pole air to go all the way across the equator up to the north. Even a small wave can be pretty strong I'm guessing.
That was my best guess. I am no math or science wiz. Just my attempt to reword it.
Remember, most math and science whiz kids probably have better things to do than be on yahoo answers late at night.

Hi. I am an amateur radio operator. We are most concerned about the 'F' layer, especially the nighttime combination of 'F1" and F2" layers, since we bounce radio waves around using these. (They combine at night which is why the local AM station you might listen to has to turn down their power.) Space craft start to experience noticeable drag at much the same height. The circulation from the equator to the polar regions is subtle yet important (and beyond my level of expertise). Just keep studying and thinking about it if it interests you and you'll get it!
