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.
