[MITgcm-support] 回复： Convection experiment!

[Jean-Michel Campin]

Hi Antony,

3 remarks: 
1) The convection set-up used in the Ocean-Modelling 2011 paper you mentionned
(super-parameterization ...) is somehow similiar to the tutorial_deep_convection
example, but resolution, domain size and parameters are different.
So I don't expect results to be the same.

2) tutorial_deep_convection has been integrated forward for much longer
than the 3 iterations provided in the short test. And it does develop
convective plumes. 
So I don't know if the problem you mentionned is because you pick 
different parameter/forcing/too-short integration
or if there is a problem in getting MITgcm compiling/running 
tutorial_deep_convection example on your computer.

3) the ridgid-lid option normally works fine. Again, unless we got more
details, I would not be able to give any helpfull comments. sorry.

Cheers,
Jean-Michel

The results should be the same with the the NH one presented in JM Campin's paper <Super-parameterization in Ocean Modelling: Application to Deep Convection>.

I have no idear what happened. Based on the free surface data, it seems that the gravity waves play a role in the horizontal motion.
