Lagrangian Measurements of Entrainment Flux in the Pacific Equatorial Cold Tongue

[00:24 . 12] [au:]赤道地区的温跃层水通过湍流过程与“冷舌”相结合，使水在两者之间夹带和混合。在过去，大型系泊阵列和遥感已经提供了热收支的其他方面的估计，除了这个携带项。pi建议通过在太平洋赤道地区部署的拉格朗日浮标上进行测量来测量这一项。这将提供湍流夹带通量的时间序列。这项研究的一个目标是更好地了解厄尔尼诺现象是如何发展的。

In the past, large-scale mooring arrays and remote sensing have provided estimates of other aspects of the heat budget except for this entrainment term. The PIs propose to measure this term through measurements made on Lagrangian floats deployed in the Pacific equatorial region. This will provide time series of turbulent entrainment fluxes. One goal of this research is to better understand how El Nino develops.
