Re: Unrealistic M2 tide amplitude in Sulu Sea, Indonesian Sea

I think you should review the straits that communicate with the Sulu Sea. At 1/12 resolution and rx0 max of 0.2 I suspect you are strongly reducing the sectional area of the straits (and hence the tidal transports). The DT you are using suggests to me that you have an extremely smooth bathymetry. A...

Re: Unrealistic M2 tide amplitude in Sulu Sea, Indonesian Sea

I suggest you focus on the South China Sea. Fix that and the Sulu Sea might be OK. Sulu Sea tide is just the tail; SCS is the dog. Note you have no phase progression across SCS. Could it be too deep? Dear johnluick, thanks for your kindly suggestion, that might be the reason, I'll have a try. You i...

Unrealistic M2 tide amplitude in Sulu Sea, Indonesian Sea

Dear all: I'm setting up a model to simulate Indonesian throughfow with explicit tidal forcing. The model configuration is simlar to the work of Liang et. al (2019) except that I have added explicit tidal forcing and potential tide. The tidal forcing is from the TPXO 7.2. The resolution of the model...

Re: Problems about adding tidal forcing in 4DVar

Dear Ivica:
Thank you for your excellent guidance, I'll have a try.
I'll report back if I have any new result.

Re: Problems about adding tidal forcing in 4DVar

Dear Ivica: Thank you for your kindly reply. It's really a surprise and encouraging to receive your reply :D , because I have read many of your papers regarding 4DVar and have been trying to follow your work. Right now I'm a phD candidate at Institute of Oceanology, Chinese Academy of Sciences. I ha...

Problems about adding tidal forcing in 4DVar

Hi, everyone: I'm using 4DVar in East China Sea. When I run the model without tidal forcing, the underestimated mixing on the continetal shelf causes bias of temperature. So I am trying to add tidal forcing when running 4DVar. Dr. Powell and his team have successfully run 4DVar in Hawaii sea with ti...
