日本海的长期平均（31年平均）地表热通量是用体积法估计的，利用大多数可用的船只资料，分辨率为1o×1o。长年平均净热通量约为- 53 W m−2（负号为上升热通量），5月为- 133 W m−2,12月为- 296 W m−2。符拉迪沃斯托克附近地区的少量热量增加似乎表明存在从北方流出的冷水。该地区冬季平均散热量约为200 W m−2，鲍文比大于1。日本海5月日晒量最大，11月上升潜热通量最大。对Haney型热通量进行了计算，结果表明，常数q1具有显著的季节和空间变化，而系数q2在各个季节的变化相对较小。在通过津加鲁海峡的体积输运1.35×106m3s−1等假设下，根据平均地表热通量的结果，估计通过对马海峡和大豆海峡的体积输运的长期平均值分别约为2.20和0.85×106m3s−1。
The long-term mean (31-year mean) surface heat fluxes over the Japan Sea are estimated by the bulk method using the most of the available vessel data with the resolution of 1o×1o. The long-term annual mean net heat flux is about −53 W m−2(negative sign means upward heat flux) with the annual range from 133 W m−2in May to −296 W m−2in December. The small gain of heat in the area near Vladivostok seems to indicate the existence of cold water flowing from the north. In that area in winter, the mean loss of heat attains about 200 W m−2, and the Bowen's ratio is over the unity. The largest insolation occurs in May in the Japan Sea, and the upward latent heat flux becomes the largest in November in this area. The heat flux of Haney type is also calculated, and the result, shows that the constantQ1has the remarkable seasonal and spatial variation, while the coefficientQ2has relatively small variation throughout all seasons. Under the assumption of constant volume transport of 1.35×106m3s−1through the Tsugaru Strait, the long-term averages of the volume transport through the Tsushima and Soya Straits are estimated to be about 2.20 and 0.85×106m3s−1from the result of the mean surface heat flux, respectively.
