Hi~ i have some question abourt relaxation method

[kobl1201]

Hello~

I applied relaxation method like this equation

T = T + dt/k(H-T)

Here, T is calculated by model, dt is time-step , k is nudging time scale, and H is external data.

If i set k = 30 day * 86400 sec, dt = 30sec, H is applied each time-step, or it is applied every 30 days.

Please Help me

[kate]

It should be applied every timestep.

Thanks Kate.


At that time, If I have that the external data is interval of 1 day, H should be updated every 1 day or every 30 days??

Have a good time

Might as well update every day if you have it.

Thank you Kate.

I understand the nudginf time scale.
