The Influence of Microscale Wave Breaking on Gas Transfer

OCE96-33423杰瑟普该项目将确定微尺度波破裂在海-气输送中作为一种强迫机制的作用。在没有空气夹带的情况下，非常短的表面重力波破裂，称为微尺度破裂，破坏了控制海气界面上气体流量的扩散亚层。因此，微尺度破碎被认为是气体传递的主要机制。这一提议将建立一种新的方法，基于实验室红外成像技术得出的微尺度破裂的定量测量来预测海-气传输速度。

OCE 96-33423 Jessup The project will determine the role of microscale wave breaking as a forcing mechanism in air-sea gas transfer. The breaking of very short surface gravity waves without air entrainment, known as microscale breaking, disrupts the diffusive sublayer which governs the flux of gas across the air-sea interface. Thus, microscale breaking has been proposed as a dominant mechanism for gas transfer. This proposal will establish a new approach for the prediction of air-sea gas transfer velocity based on quantitative measures of microscale breaking derived from infrared (IR) imaging techniques in the laboratory.
