It is asserted that coherent structures in turbulence-CS, in particular
atmospheric and ocean phenomena, hurricanes, tornadoes, jet streams,
ocean currents, etc. are at the core Beltrami-Trkal coherent
clusters-BCC. The chaotic motion is created as an environment, by
induction mechanism, by this skeleton like coherent turbulence core.
The assertion is compared with turbulence direct numerical simulations-
DNS, laboratory experiments and diverse experimental obseravations.
