The Beautiful Roles of the Earth

The Beautiful Roles of the Earths Rotation

• Every thing can be beautiful for a pure heart
  in a clear hand! The climate rhythm is beautiful
  abundant music even if proud hands pollute our
  environment, destroy atomsstructure, and send
  the nuclear empoison into above the tropopause
  where there is no water available for cleaning.
  The global warming in a century seems ok for a
  geological process, were nothing but partial
  phase of little ice age, and would be drawn
  back to the normal by the negative feedbacks
  strong enough triggered someday. However, if we
  are sure that our activities matter to this
  warming, even half degree of warming should be
  big enough to cause our concern about our
  environment. It is feasible for each person to do
  something from now on for saving our environment.
  Saving a piece of paper is saving trees and
  reducing the paper-making associated pollutions.

1. Sustaining Rotation of the Earth

• 1-1.Rotation associated Coriolis force does not
  do the work on the objects (fluids) at any time
  therefore, the rotating system does not consume
  ones energy and keeps ones original angular
  momentum.
• Coriolis force and its work on the objects
• 1-2.Rotation velocity does not change much even
  though bothered by abnormal mass distribution on
  the surface.

• Similar force exists in magnetic field, but the
  bioelectricity inside our bodies should never be
  bothered by magnetic field.
• Force from a magnetic field ( ) exerted on a
  charged particle (q) with instantaneous velocity
  ( ) and forces work anytime are,

2.Rotation associated Coriolis force maitains a
relatively orderly and steady geophysical motion
and corresponding weather and climate.

• Coriolis force balances most of gradient
  force to produce geotrophic motion ( ) moving
  along iso-bars, keeping most fluids from moving
  from high to low pressure. Coriolis force
  associated Ekman transport ( ) makes fluids
  from low to high.

3.Rotation associated geotrophic motion increases
the predicability of geophysical fluids as it
causes geotrophic motion waves (Kelvin,Rossiby,
inertial, etc.).

• The curvature force friction
  are small. Coriolis force and pressure gradient
  force are two main items in kinetic balance,
  which dwarf the nonlinear item. Without Coriolis
  force, pressure gradient force would be very
  small, the horizontal kinetic equation would be,
• The nonlinear item stands up, making the
  geophysical motion much more unpredicable.

4.The Earths rotation can muffle the Sun-Moon
gravitation-induced flow keep the geophysical
fluids from heaping onto a fixed direction, for
fluids of small viscidity the vertical speed of
which can increase by 29 (for the Moon) to 365
(for the Sun) times if without rotation. This
maybe is one of the reasons why there is no
fluids on the Moons surface. For solids or
fluids of very big viscidity, rotation does not
that matter.

• The ratio btn the momentums in x z
  directions under the Suns or Moons attraction
  without and with Earths rotation can be
  estimated as,
• For fluids of small viscidity, the
  vertical speed can increase by ( 365 for the
  Sun, 29 for the Moon) times. For solids or
  fluids of very big viscidity , rotation does not
  that matter.
