Full‐Depth Scalings for Isopycnal Eddy Mixing Across Continental Slopes Under Upwelling‐Favorable Winds

Maintaining Continental Slopes

Although water vapor is the most important greenhouse gas, it is not even agreed whether an increase in its concentration due to global warming will cause more warming or cooling. Warming (a positive feedback) will occur if the biggest effect is to absorb more outgoing long-wave radiation. Cooling (a negative feedback) will occur if the major result is to form more clouds, which would reflect m...

Isopycnal mixing and the distribution of particles across the North Pacific Subtropical Front

-Vertical profiles of salinity S and beam attenuation coefficient c were obtained from the research platform R.P. Flip as it drifted across the North Pacific Subtropical Front (NPSF) during the Optical Dynamics Experiment (ODEX) in the autumn of 1982. Near-surface waters north of the NPSF have lower S and generally higher values of c compared with waters to the south. An anomaly in c is used to...

Eddy mixing in jet-stream turbulence under stronger stratification

[1] Certain qualitative changes in turbulent eddy mixing during transitional regimes towards stronger stratification are highlighted using high-resolution numerical simulations. The behavior of turbulent eddy mixing parameters found in this study is consistent with some recent observational results in stably stratified shear flows in the atmosphere. In particular, the flux Richardson number inc...

Pii: S1463-5003(99)00002-5

In regions of sloping isopycnals, isopycnal mixing acting in conjunction with biological cycling can produce patterns in the nutrient ®eld which have negative values of tracer in light water and unrealistically large values of tracer in dense water. Under certain circumstances, these patterns can start to grow unstably. This paper discusses why such behavior occurs. Using a simple four-box mode...
