I want to work on large scale blending in WRF but I'm unable to locate the relevant code or modules.
Kindly guide me on where this functionality is implemented or how it can be incorporated.

Can you clarify what you mean by " large scale blending "?

 

[Akash6139]

By “large-scale blending,” I mean incorporating the large-scale information from a host/global model (e.g., GFS or FNL) into a regional WRF simulation, while retaining the high-resolution features generated by the regional model. with the help of low pass filter large scale features or information can be extracted. This type of work involves combining large scale features from Host (global) model and small scale features from regional model.

WRF has the capability of nudging large scale information. Please see the document here.

Thanks for your information sir But i am curious to know about this type of work done in this research paper

Kindly Guide me for Large scale blending related code and module.

Would you please contact the author(s) for more information? Due to limited human power, we cannot explore each individual user's approach in their WRF application.
