关于涡相关海气通量计算的资料处理技术
, PP. 1-5
Keywords: 海气通量,涡相关方法,动量,惯性耗散法,湍流脉动
Abstract:
针对海气通量观测中存在的气流扰动等非湍流信号影响风速脉动进而导致涡相关通量计算失真的问题,借用惯性耗散法的思想进行了资料处理技术的改进性研究。以湍流惯性耗散的-5/3密率分布为依据,获得了一种滤除非湍流信号的新途径。以动量通量的计算为例,从对实测风速数据的处理情况来看,其结果与经验公式所得吻合得非常好。相比于通常的通量计算软件来说,该资料处理技术能极大地降低非湍流信号的影响并由此得出更为可靠的通量结果。从而,此技术可以用于新通量算法软件的研究和开发。
