Subj: More on wobbles
Dear Dr. Dickman/Steve,
Hi Again. Keep working on that book. Guess you know most of what
follows --- you taught me.
More on wobbles. Annual Wobble, Chandler Wobble (Peak1), Chandler
Markowitz wobble???, offset, trend etc.
Earth Orientation Phenomena: Precession, Nutation, Rotation(Earth
Spin), Diurnal Wobble???,
Annual Wobble, Chandler
Wobble 1, Chandler Wobble 2 etc.
Still thinking about wobble beats. Chandler wobble amplitude has
maxima at roughly:
1910, 1954, 1998,
In reality though, what goes on at the time of the Chandler Wobble
peaks is that there is a
rather wide variation in Earth dip towards the Sun (about some mean
position) and away from the
Sun, thus producing times of relative warmth and relative cold.
Maybe this is what we are seeing
lately from 1998 and a bit onward. Thus there are warmer Summers and
Of course, the Earth does travel around the Sun and we experience the
various Earth Seasons,
as usual. Temperature variability causes wide variation in the
moisture content in the
atmosphere. Ice Caps Melt, Sea Level Rises Etc.
At times of Chandler Wobble amplitude minima (1932, 1976, 2020)
there is not a great deal
of wide variation in the actual dip angle towards the Sun. Things
behave in a rather steady
average manner. There is not-so-much free water vapor in the
atmosphere, thus causing
droughts???? The large snowfalls like in 1888 (New York City), I'm
still hard pressed to
So there you have it. Classical Physics explanations of the
various Earth wobbles explain
some of the Climate we see. Anyone ever having programmed such
phenomena in NASA
Goddard Space Flight Center's VLBI (Very Long Baseline Interferometry)
CALC and SOLVE could witness that all this is anything but simple.
Take Care... Joseph R. (Joe) Preisig
