摘要

During the summer heating, the thermocline conserves the cold intermediate layer (CIL) from above and the halocline converves it from below. The role of the volume absorption of solar irradiance by water and that of the horizontal heat transport increases in the process of the CIL transformation. Surface particles travel around the entire sea transported by the main stream of the Black Sea Rim Current and, on the average, return back after 200 days, while the particles of the CIL cover this distance in four months. Thus, the temperature of the CIL in this stream strongly depends on adection. The order of heat fluxes in the CIL from above q arrow down and below q arrow up is estimated for July. In the deepwater part of the sea, q arrow down = 3.9 X 10~(-5) and q arrow up = 2.4 X 10~9-5) cal/cm~2s. From July to September, the temperature growth in the core of the CIL as 0.5 deg C. Two-thirds of this growth is due to the absorption of solar irraiance and about one-third is due to q arrow down + q arrow up. By the end of water heating (September), the CIL temperature in the horizontal direction over the entire sea basin changes by 0.1-0.2 deg C only.
