Re: Spurious supercooling in ROMS-CICE simulation

It is not easy to say what kind of signal will occur around rough topography. If your S-coordinate intersects with pycnocline with big angle and if a strong cross-isobathic flow is present, artificial "diapycnal mixing" may occur around the slope. A general impression of this numerical phenomenon is ...

Re: Spurious supercooling in ROMS-CICE simulation

Hi this is Hui Wu (HSIMT). Kaitlin, it seems you have some new results with HSIMT, right? I am not familiar with ROMS code, Tarandeep in John's group helped to rewrite the HSIMT code for COWAST. It is very hard to evaluate an advection schemes in realistic simulations, since there are too many ...

Re: Abnormal warm on seawater temperature.

Over-heating or over-cooling might occur occasionally when using prescribed heat flux to drive the model, especially in shallow area, to my own experience. Let's say a positive heat flux is prescribed, i.e. the sea receives the heat from air. In reality the ocean temperature will rise thus reduce ...

Re: How to calculate Stokes velocity

Guys, it seems you are talking about two different things :D . John, perhaps wuting0926 wants to calculate the tide-induced Stokes drift, not the wave-induced Stokes drift. There are couple of ways to define the tide-induced Stokes drift, based on pure Lagrangian or Eulerian perspectives. As ...
