THEORY ON NON-LOCAL MULTI-SCALE TURBULENCE FOR BOUNDARY-LAYER HEAT TRANSPORT WITH ITS EXPERIMENT

Following theories on multi-scale turbulence and transilient turbulence in the atmospheric boundary layer, a method is developed for non-local multi-scale turbulence for sensible heat flux and using data from Changdu station as the base for all-item observations in the second Tibetan Plateau Experiment (TIPEX) from May to August, 1998, sensible fluxes are calculated by means of a technique for non-local multi-scale turbulence and a classic similarity scheme separately. Analysis of the calculations shows that the first method is responsible for the upgradient transport of sensible heat and for the higher fluxes in the near-neutral stratification over the Plateau. Besides, the multi-scale theory needs further improvement in an effort to raise the precision of the calculations.
