摘要:

文章给出了青藏高原能量水分循环研究的概况和总结,着重估计了能量平衡各分项和湍流热通量等。在能量平衡的计算基础上,尽管能量不平衡的原因解释仍有争论并且没有解决,但我们揭示了GAME/Tibet试验观测资料中能量不平衡现象。我们发现估算的潜热通量比实际观测的要高许多。然而,根据能量平衡假设的计算结果和SEBS的估算一致性很好。在此基础上可以归纳出差异主要由GAME/Tibet试验观测资料中能量不平衡引起,潜热通量的实际观测可能偏小。

Abstract:

This contribution presents an overview and an outlook of studies on energy and water cycle over the Tibetan plateau with focuses on the estimation of energy balance terms and turbulent heat fluxes. On the basis of the surface energy balance calculations, we show that the phenomena of the energy imbalance exist in GAME/Tibet experiment data, although the explanations for the reasons are debated now and not resolved yet. We found that the derived latent heat flux is much higher than the measurements. However, the corrected-measurements, which are calculated according to the hypothesis of the energy balance, compare very well with the estimation of SEBS. On this basis it is concluded that the deviation is caused by the energy imbalance of ground measurements in GAME/Tibet experiment area. The latent heat fluxes were likely under-observed.

Key words: Energy balance    Energy and water cycle    The Tibetan plateau    Turbulent fluxes
