      It seems to me your model describes a static flat ocean surface. You say that heat transfer from the upper 1 mm to water below can only occur by convection. Convection is driven by temperature related density difference. But in the real ocean the upper surface layers are surely substantially and continuously mixed by wind induced wave action.

    The book consists of four parts. Part I (chapters 1 - 4) is a very brief introduction to ocean circulation and the mathematical formulation of the governing equations of ocean flows. In addition, concepts are introduced that are necessary to describe and understand large-scale ocean currents.

Upper-Ocean Heat and Salt Balances in the Western Equatorial Pacific in Response to the Intraseasonal Oscillation during TOGA COARE July Journal of Climate 13(14) Turbulent mixing in the equatorial Pacific Ocean is an important process that controls diapycnal heat transport and hence affects the air-sea interactions and global climate.

The proportion of these physical processes to the cooling of the OML heat budget are shear-driven entrainment mixing (60–85%), surface heat and moisture fluxes (Q o) (5–15%), and horizontal advection by ocean currents (5–15%) under relatively quiescent.

For both atmospheric and oceanic general circulation models, prognostic equations governing the conservation of momentum, heat, mass and water substance (or salt in the case of the ocean) are solved numerically over the globe at a set of discrete levels in the vertical.

The goals for the international WOCE are (1) to collect the data necessary to develop and test ocean models useful for predicting climate change; (2) to determine the representativeness of the specific WOCE data sets for the long-term behavior of the ocean; and (3) to find methods for determining long-term changes in the ocean circulation.

Unlike the upper layers, which are dominated by the annual cycle of heating and cooling, they argue that deep ocean trends must be viewed as part of the ocean’s long term memory which is still responding to “meteorological forcing of decades to thousands of years ago”. If Balmaseda and Trenberth’s model of deep ocean warming was correct.

San Diego, CA, February 21. Again, the turbulent mixing of heat and momentum and the hydrostatic response to the former are implicated. Just as the SST front of a western boundary current can produce mesoscale solenoidal circulations, meanders in that front can focus those circulations into bands when the synoptic winds align with the meander axis (Young and Sikora ).Cited by: 1.

In Pacific Ocean–Global Atmosphere (POGA) experiments, SST anomalies in the equatorial eastern Pacific (% of the Earth’s surface) follow the observed evolution (see Methods).

In POGA-H, the radiative forcing is identical to HIST, and in the POGA control experiment (POGA-C) it is fixed at the value [natural internal variability only].

Page In each of the six sections of this chapter, the discussion is partitioned into subsections dealing with the influence of the particular climate-system component on climate attributes, the evidence of variability and change of that component on dec-cen time scales, and the mechanisms through which that component operates within the climate system.

The subject of ocean turbulence is in a state of discovery and development with many intellectual challenges. This book describes the principal dynamic processes that control the distribution of turbulence, its dissipation of kinetic energy and its effects on the dispersion of properties such as heat, salinity, and dissolved or suspended matter in the deep ocean, the shallow coastal and the.

Ocean measurements. Long-term time series are being collected through multiyear mooring deployments, which include a six-element water column subsurface array distributed between 5° and 8°N and ° and °E in the southern BoB and a solo deployment near 18°N, 89°E in the northern BoB (Figs.

1, 2a,b). The NRL-led southern array was. The solar heating is input at the top which stabilizes the temperature profile, but the winds cause a turbulent ‘convection’ that mixes the heating through a considerable depth. This wind mixed layer is on the order of 50m.

In contrast, heat must be conducted into and out of subsurface soil, a much slower process than wind mixing. The ocean–atmosphere exchange of insoluble gases and sparingly soluble chemical species such as CO 2, as well as other properties such as heat and momentum, is controlled by the mass boundary layer occupying the upper 10– μm of the ocean surface.

Within this boundary layer, molecular diffusive transport tends to dominate over turbulent Cited by: This banner text can have markup. web; books; video; audio; software; images; Toggle navigation.Tourre, Y.M., Y.
