That's weird, from two GA Tech scientists in 1965 talking about atmospheric oscillation.
Weird because if the earth were spinning why would you ever want to run tests assuming it's not? Reminds me of Einstein's famous quote. "Since then I have come to believe that the motion of the Earth cannot be detected by any optical experiment, though the Earth is revolving around the Sun.”
"A model frequently used is that of a flat, nonrotating earth. The temperature is assumed either to be constant,to increase or decrease monotonically with altitude, or to be stratified. Gravity is usually considered to be constant.
Density and pressure are usually considered to vary exponentially with altitude.
The most one can profitably simplify the problem is to consider an isothermal
atmosphere, plane level surfaces, and a nonrotating earth. This case has been
handled by Eckart [1960], Lamb [1932], and Hines [l96O].
Eckart [l960] went through a second derivation in which the effect of the
earth's rotation was included. He again found that certain frequencies are not allowed and the
acoustic and gravity waves are similar to the ones already described. Figures
2 and 3 show these allowed frequencies versus wave number in the cases of a nonrotating and a rotating earth.

Ed McQuarrie talks the REAL History of Stocks and Bond performance.
We're taking my son to his Introduction to Auburn event at Auburn University.
we'll see you next week though!
In the meantime, a white paper I'm reading.
"This study validates...that the implementation of (China's) Five Year Plan was followed by a significant production expansion in the encouraged sectors of China. This expansion crowds out production in the same sectors in the US, leading to significant drops in both employment and investments and a notable increase in plant closures."
But it's TRUMP that started the trade war, eh?
sorry folks gotta move all this mulch by this weekend.
WE're preparing for my son Cavan's high school graduation party. So, it's a BIT hectic here to make sure everything is in place...
If it was me, I'd grill burgers and sit on coolers full of water. But apparently I'm not in charge. Who knew?
