为了研究水面通量的空间变异性，在移动平台上进行湍流测量是有用的。然而，这种测量只在海洋上的大型研究船上进行过。我们测试了通量测量的可行性与一个小游览船在霞浦湖，在日本的第二大湖泊。在正式应用坐标旋转来解释船舶的运动之后，我们推导出了平均风速以及潜热和感热通量。将它们与气象站的空间插值风速和整体方法估计的通量进行了比较。同样好的协议被发现与以前的研究报告在海洋上，表明船舶测量在湖泊中的可行性。为了提高通量估计的精度，分析了可能的误差来源。
: To study the spatial variability of water surface fluxes, turbulence measurements on a moving platform are useful. However, such measurements have only been carried out with large research vessels over the ocean. We tested the feasibility of flux measurements with a small excursion ship over Lake Kasumigaura, the second largest lake in Japan. After the formal application of coordinate rotations to account for the ship’s movements, we derived mean wind velocities as well as latent and sensible heat fluxes. They were compared with spatially interpolated wind velocities from meteorological stations and with fluxes esti‐ mated from the bulk method. Equally good agreements were found with those reported in previous studies over the ocean, indicating the feasibility of ship measurements in a lake. Possible error sources were identified for the improvement of the accuracy of flux estimation.
