| 摘 要： | 基于2016-02-01—2016-05-21在南海博贺海洋气象观测平台观测的实验资料,首先利用整体空气动力学算法分别计算海气界面处感热通量与潜热通量,同时利用涡动相关法计算液滴蒸发层处总的感热通量与潜热通量。然后比较海气界面处热通量与液滴蒸发层处热通量的值,并利用差比法分别对2处感热通量和潜热通量进行做差计算。结果表明:液滴蒸发层处热通量与海气界面处热通量存在明显差异。通过与海洋飞沫引起的热通量值比较,结果表明液滴蒸发层处热通量与海气界面处热通量的差值由海洋飞沫作用引起;且在中低风速条件下,海洋飞沫引起的热通量与风速呈正相关;相比感热通量而言,潜热通量随着风速的变化更为显著。

| Abstract: | Based on the in situ measurements obtained by the Bohe observation platform in the South China Sea from February 1 to May 21, 2016, heat flux at sea surface is calculated with bulk-aerodynamic method, and that in droplet evaporation layer is then estimated with eddy covariance method. By comparing the fluxes at sea surface and in droplet evaporation layer, we found that significant difference exists between them, and sea spray is responsible for it. It is also found that the heat flux caused by sea spray is positively correlated with wind speed when the wind speed is medium and low. From the point view of sea spray formation mechanism, latent heat flux changes are more obvious than sensible heat flux changes at same wind speeds. |
