Gravity Wave???

LiveLeak.com - Gravity Wave

first didnt know this exsisted

here is the sites definition


Now let's look at what a gravity wave is in the atmosphere. To start a gravity wave, a TRIGGER mechanism must cause the air to be displaced in the vertical. Examples of trigger mechanisms that produce gravity waves are mountains and thunderstorm updrafts. To generate a gravity wave, the air must be forced to rise in STABLE air. Why? Because if air rises in unstable air it will continue to rise and will NOT create a wave pattern. If air is forced to rise up in stable air, the natural tendency will be for the air to sink back down over time (usually because the parcel forced to rise is colder than the environment). The momentum of the air imparted by the trigger mechanism will force the parcel to rise and the stability of the atmosphere will force the parcel of air to sink after it rises (you have now undergone the first steps into creating a wave)...

Yea, I'll check it out. Liveleak has some pretty messed up videos, you're lucky you accidentally posted that one.

Re: Gravity Wave???

About a year ago we had a 3rd magnitude register on a Richter scale at “Disney World” when an F14 threw a shock wave at Florida screwing around. When you become sub-sonic and bank, it throws it. It wasn’t a sonic boom, the only sound was like someone pounding on the doors and windows.

Either your computer is old and your browser us outdated, or you have scripting turned off (in IE that would be your security is set to high)

Thanks, I’ll get my daughter on it as soon as she gets up… The computer is brand new and she set it up.
