摘要：在 1974 年 3 月发生微风（∼2 m s−1）的 3 天内，对西北非洲海岸附近的一个小区域（∼2 km×2 km）的热收支进行了调查。热量的水平平流和扩散可以忽略不计，热量含量的局部变化是由海面的净辐射和蒸发通量引起的。昼夜加热使表面温度在 3 天中的每一天的范围分别为 0.9、1.1 和 1.4°C。利用日间热浪随深度的指数递减来估算上层10 m的垂直涡热导率；获得大约 10−3 m−2 s−1 的值。
Abstract The heat budget of a small region (∼2 km×2 km) near the coast of northwest Africa was investigated during a 3-day period in March 1974 when light winds (∼2 m s−1) occurred. Horizontal advection and diffusion of heat were negligible, and the local change in heat content resulted from the net radiative and evaporative flux at the sea surface. Diurnal heating produced surface temperature ranges of 0.9, 1.1 and 1.4°C for each of the 3 days. The exponential decrease of the diurnal heat wave with depth was used to estimate the vertical eddy thermal conductivity of the upper 10 m; values of approximately 10−3 m−2 s−1 were obtained.
