Thank Dennis Shea!
However, I couldn't find that uv2dvf or uv2vrF use triangular truncation from the two web page in which it dosen't give any information about spectral truncation. If uv2dvf takes T42 as its defult spectral trunction for divergence caculation, how could I complete it with T21? I'll be very glad if anyone could give me more suggestion! Best regards!
