A Direct Method of Observing Ocean Heat Flux

这项SGER计划提案的目的是用一种直接测量海洋热通量的新仪器来测试漂流和系泊浮标。通常，这些观测是在海洋表面以上的大气中间接进行的，既难以进行，也没有期望的准确性。新仪器模拟了将海洋与大气分开的“膜”，并测量了通过它的热流。该仪器简单，可以从第一性原理进行校准，也可以在零风条件下工作。这些特性使其成为TOGA/COARE计划的一部分，也可能是CEPEX计划的一部分，在太平洋暖池区获得热通量观测的理想地点。由于大多数算法都需要风，因此对该区域的边界层进行建模尤其困难。这些设备的观测可以提供关键信息，有助于更好地了解该地区的边界层。这种仪器在海洋的其他地方也应该能很好地工作。这项研究很重要，因为它旨在提高收集与气候变率和变化有关的大气-海洋相互作用研究至关重要的信息的能力。

The objective of this SGER Program proposal is to test both drifting and moored buoys with a new instrument which measures the ocean heat flux directly. Typically, these observations are made indirectly in the atmosphere above the ocean surface and are both difficult to make and do not have the desired accuracy. The new instrument simulates the "membrane" which separates the ocean from the atmosphere and measures the heat flow through it. The instrument is simple, can be calibrated from first principles, and will also work in zero wind. These properties make it ideally sited for obtaining heat flux observations in the warm pool region of the Pacific as part of the TOGA/COARE, and possibly also the CEPEX, program. Modelling the boundary layer in this region is especially difficult because most algorithms require a wind. Observations from these devices could provide key information that should aid in a better understanding of the boundary layer in this region. The instrument should work well in other parts of the ocean as well. This research is important because it seeks to improve on ability to collect information vital to the study of atmosphere- ocean interactions related to climate variability and change.
