Constraints placed by silicon cycling on vertical exchange in general circulation models
The flux of biogenic silica out of the oceanic mixed layer (the export flux) must balance the import of high-silicate deep waters associated with mass exchange between the surface and deep ocean. Recent regional estimates of the export flux limit it to 50-80 Tmol yr. In order to reproduce such low export fluxes, coarse-resolution general circulation models must have low pycnocline diffusivity a...
متن کاملEstimation and Analysis of Caspian Region's Future Rainfalls by Using General Atmospheric Circulation Models.
In recent years, the severe fluctuations in precipitation have affected various parts of the country. On the southern coasts of the Caspian Sea, precipitation as one of the important climatic parameters has undergone changes due to global climate change. In the present study, we tried to evaluate the effect of climate change on rainfall in this region by applying a suitable model. In this study...

15 صفحه اولConstraints on mantle He fluxes and deep-sea circulation from an oceanic general circulation model
We have simulated the steady-state distribution of helium in the deep sea to investigate the magnitude and spatial and temporal variability of mantle degassing and to characterize deep-sea circulation and ventilation. The simulation was produced by linking a simple source function for helium injected at mid-ocean ridges with an oceanic general circulation model (GCM). By assuming that the flux ...
متن کاملVertical Mixing , Energy , and the General Circulation of the Oceans
■ Abstract The coexistence in the deep ocean of a finite, stable stratification, a strong meridional overturning circulation, and mesoscale eddies raises complex questions concerning the circulation energetics. In particular, small-scale mixing processes are necessary to resupply the potential energy removed in the interior by the overturning and eddy-generating process. A number of lines of ev...
