Summary
Atmospheric flows exhibit long-range
spatiotemporal correlations or non-local connections manifested as the
fractal geometry to the global cloud cover pattern concomitant with inverse
powerlaw form for power spectra of temporal fluctuations. Such non-local
connections are ubiquitous to dynamical systems in nature and are recently
identified as signatures of self-organized criticality, a field of study
belonging to the newly emerging science of nonlinear dynamics and chaos.
Mary Selvam (Can. J. Phys. 1990: 68, 831) has proposed a
model, which identifies non-local connections in atmospheric flows as intrinsic
to quantumlike mechanics governing flow dynamics. The model is based on
the concept that spatial integration of enclosed small-scale fluctuations
gives rise to large eddy circulations. The eddy energy spectrum therefore
follows statistical normal distribution, i.e., the additive amplitudes
of eddies, when squared, represent probability densities. Such a result
is observed in microscopic quantum systems such as the electron or the
photon. The model predictions are as follows. (1) The overall flow trajectory
traces a logarithmic spiral with the quasiperiodic Penrose tiling
for the internal structure, thereby resulting in non-local connections.
(2) Wave-particle duality is attributed to bimodal (formation and dissipation
respectively) phenomenological form for display of energy in the bi-directional
(updrafts and downdrafts) energy flow intrinsic to eddy circulations, e.g.,
cloud formation and dissipation respectively in updrafts and downdrafts
in atmospheric flows. (3) Atmospheric eddy circulations follow Kepler’s
third law of planetary motion. The centrifugal forces representing inertial
mass therefore follow the inverse square law analogous to Newton’s
law of gravitation. The model therefore is equivalent to a superstring
model (Kaku, New Scientist 18 Jan.1997, 32) for quantum gravity.
Model concepts
The model is based on the concept that
spatial integration of enclosed small-scale circulations gives rise to
large eddy circulations. The root mean square (r.m.s) circulation speeds
W and w* corresponding to radii R and r
respectively of large and turbulent eddies are related by the equation
(1)
(1)
In the above equation nR
and nr
are the respective frequencies. Since W2 represents the
kinetic energy (K.E) ER of large eddy
The constant H is proportional
to K. E. (kinetic energy) per cycle/sec of turbulent eddy. H is
therefore equivalent to Planck’s constant for microscopic quantum
systems. A nested (hierarchical) continuum of progressively increasing
eddy circulations are generated starting from persistent primary small-scale
fluctuations.
Expressing Eq.1 in terms of the
periods T = 2pR/W
and t = 2pr/w*
for a given primary dominant turbulent
eddy of radius r and period t. The eddy circulations therefore
follow laws analogous to Kepler’s third law of planetary motion.
The centrifugal force FR of large eddy obtained from
Eq.1 as
FR
= W2/R »1/R2
for a given primary dominant turbulent eddy. The hierarchical eddy continuum
generated from a given primary dominant eddy fluctuation has centrifugal
forces which follow the inverse square law form analogous to Newton’s
inverse square law for gravitation. The model concepts therefore predict
quantumlike mechanical laws concomitant with inverse square law for centrifugal
forces, which represent eddy inertial masses equivalent to gravitational
masses.
