Dear friends,

I'm from Brazil and I'm using RegCM model for my doctoral thesis. I use version 4.1 and noticed that the wind data preprocessed by ICBC are somewhat different when using NORMER (Normal Mercator) projection. When I use ROTMER (Rotated Mercator) projection to generate the initial and boundary conditions, wind fields generated by ICBC and the source data are very similar. Other variables generated by ICBC do not differ from source data. I tested this in versions 4.1.1 and 4.2 and the error persists in relation to the wind field.

Recently, Suman Maity from India reported a similar problem, though he had not related to different map projections.

Someone confirm if this bug is really happening? If so, there is correction?

If someone wants, I can attach the pictures in the email.

Thank you,

Felipe.
