| 摘 要： | 该文在大气边界层多尺度湍流理论和湍流穿越理论的基础上，建立了大气边界层感热通量的非局地多尺度湍流计算方法，并选用1998年5～8月份第二次青藏高原大气科学试验（TIPEX）的大气边界层综合观测基地昌都站观测资料，分别用感热通量的非局地多尺度湍流计算方法和经典相似理论计算感热通量。对计算结果的对比分析表明，用感热通量的非局地多尺度湍流计算方法能计算出感热通量的逆梯度输送，也能计算出青藏高原近中性层结条件下明显的感热通量。此外，多尺度湍流理论还有待进一步发展完善，提高感热通量的计算精度。

| Abstract: | 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. |
