From: Robin van Spaandonk
I suppose the obvious
answer is the atmosphere is in constant motion in a closed system,
so it is inevitable that concentrations of air arise at times. Yet
this is not an explanation that I am particularly happy with.
Perhaps you could supply the conventional explanation?
left as an exercise to the student?
the conventional explanation involves the westernly flow of the upper
atmosphere which moves clockwise around the ridges and windershins around
the troughs -- the resulting sinusoid westernlies may number 3 to 5 waves
around the hemisphere
ah, but, grasshopper, i believe you seek a greater truth
consider the earth as a cathode supplying electrons to the sun and the
variance of the peaks of the westernlies with the axis to the ecliptic
how is your spring downunder?
