Description
On the basis of observation data of water temperature and salinity at Uranouchi Bay during the convection period, the heat flux of sea surface cooling, the potential energy given to the water column by the heat flux, and the dissipation energy are estimated. The diameter and the circumference speed of the maximum convection eddy caused by surface cooling are also evaluated. These results are described as follows : ① The heat flux through sea surface is 130(Jm-2s-1) in December. It's almost the same as the estimation about Mikawa Bay by other methods. ② The potential energy per unit time (deQ/dt) given to the water column by the heat flux is (4-17) × 10-5(Jm-3s-1). More than half of deQ/dt tums to the potential energy of water column, and the remainder turns to dissipation energy (thermal energy) and disappears. ③ The diameter of the maximum convection eddy caused by surface cooling is about 0.4 (m). The circumference speed of the eddy is about 0.001 (ms-1).
