Nature Cycles Energy Physical Biological
ruptures complacencies towers
Krakatau easterlies Berson westerlies
wind above equator oscillates
in direction wind in stratosphere
changes cyclic direction averages
changes every twenty-six months
alternating easterly westerly wind
regimes descend with time changes
nature insists climatic cyclic changes
vertically propagating waves
maximum acceleration occurs
below maximum phase speeds
leading to descent maximum with time
theory equatorially trapped Kelvin waves
provide westerly momentum Rossby-gravity
waves provide easterly momentum
to produce Quasi-Biennial zonal wind
oscillation nature adores momentum
