Thanks for the explanation, Paul! So the "pauses" are the transition
areas
between the "spheres" where the chemical composition of the lower sphere
is
changing into that of the upper sphere. Do I have that right?
Of course if that is true, then what about the ozone layer? Is the ozone
actually part of the tropopause?

Are nacreous clouds and noctilucent clouds ever visible to us on the
ground?
