The circulation consists of two northwestward flowing surface currents originating from the two passages providing connections to the Baltic, one on either side of the basin, and a southeastward flowing countercurrent to the west of the eastern current that flows along the Swedish coast. The flow from the two northwestward currents, jointly called the Baltic Current, eventually combines and joins the North Jutland Current (NJC) as it turns around and becomes the Norwegian Coastal Current. The countercurrent originates as part of the NJC turning and flowing southeast. See Svansson (1975).
Another way of saying this is the the absorptivity and emissivity of a substance are equal and any single wavelength.
