摘要：

回顾了前人对感热通量的分析研究,详细分析了计算感热通量公式的推导过程。结合GAME/Tibet那曲近地面通量观测站1998年6月6日到9月13日的观测资料验证了近地面层逆梯度热输送现象的存在;并比较了两种不同计算感热通量的方法。同时,对简化生物圈模式(SiB2)计算感热通量方案进行了分析。主要结论有:(1)由于用涡旋相关法测量得到的总体感热通量本身已经包含了非局地热(冷)泡运动的影响,所以在非均匀下垫面上,传统的闭合方案必然会“遭遇”能量不平衡。这里,非均匀下垫面可能是导致能量不平衡的关键所在。(2)在今后的有关热通量研究中,有必要仔细研究非局地热(冷)泡运动对热通量的贡献,而为了更好地理解这种贡献,应用陆面过程模式研究能量平衡是必需的。
