| Research Abstract |
As the first step toward the establishment of “pan-planetary oceanography”, which should consider the oceans on all possible planets including extra solar planets that could be very different from the earth, the circulation of an ocean covering a synchronously rotating planet is investigated using one-layer ocean model. Even when the ocean is forced only by the rainfall and evaporation in the day-hemisphere without the forcing by wind, the flow is dominated by zonal flow encircling the planet, which would transport non-negligible amount of heat from the dayside to night-side. The oceanic flow, and the heat transport thereby, is estimated to be much stronger if the forcing by wind is considered.
