how to add stochastic terms

[wongchieh]

hello! I am new to using lagragian analysis to simulate the currents. I have read your article Lagrangian ocean analysis: Fundamentals and practices, which is very detail. and I am interested, also confused, in the section 3.3,'Computing stochastic trajectories to simulate diffusion and unresolved physics', I still am confused with how to add stochastic terms when using parcels to simulate. I wonder if you could tell me how to add them or you could send me some papers which the stochastic terms are taken into conditions, it would be better that there are codes I could compared.

I am sorry to disturb you in this web. For a new one using this method, it has long way to go. If you could take your time to help me, I would be grateful. If not, thank you all the same.

Dear @wongchieh, thank you for raising this point. This Issue tracker really is meant for technical issues with Parcels, so it's easiest to answer the part about how to add stochastic terms in Parcels. We have a few built-in Kernels for diffusion, see http://oceanparcels.org/gh-pages/html/_modules/parcels/kernels/diffusion.html
