On the relation between sea-surface heat flow and thermal circulation in the ocean

Abstract

A theoretical framework for the description of the thermal state and circulation in the ocean is presented. Relations between differential heating, diffusive heat flux and surface drift are derived and discussed in the light of the basic mechanical property of the system, i.e. the tendency for light water to spread on top of heavier water. We find that for low and medium temperatures, the poleward surface drift can be determined directly from a knowledge of the heat flux through the sea surface. Preliminary quantitative estimates indicate that the “Hadley circulation” for the entire ocean involves a volume flux of order 70 ± 30 Sverdrup. For the North Atlantic we find a poleward drift of order 10 Sverdrup which compares well with previous estimates of the southward deep flow. Mean values for the diffusive flux in the ocean are found to be of order 20 W m-2 at 15°C and 60 W m-2 at 25°C.

  • Neglecting mixing in the ocean interior, the time-averaged residual meridional transport is entirely determined by the knowledge of air-sea buoyancy fluxes.

    “Neglecting mixing in the ocean interior the time-averaged residual meridional transport is thus entirely determined by the knowledge of airsea buoyancy fluxes (Walin 1982;Marshall 1997).”

    Section 4 says that surface heat flux can directly estimate the poleward surface drift and associated circulation when the mixing term is negligible, particularly at low and medium temperatures. It does not establish that air–sea buoyancy fluxes entirely determine the time-averaged residual meridional transport; for high temperatures, it says the mixing term is vital. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
