[RegCNET] Error in wind field preprocessed by ICBC, when NORMER is used

[Felipe Roque]

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.
