The authors are most grateful to the anonymous referees for their detailed comments and reviews. We would also like to thank the following: M. Desgagné, S. Thomas, and C. Girard for the support to the MC2 model (AES/RPN); S. Laroche and S. Pellerin for their precious help for the use of 3D variational analysis system (AES/RPN); A. Méthot and M. Roch for the support with the GEM model (AES/CMC, RPN);C. Beaudoin for the support with the SEF spectral model (AES/RPN); and J. St.-James for the surface fields used at very high resolution (AES/CMC). This work also benefited from precious discussions with S. Bélair and B. Bilodeau concerning the precipitation schemes used (AES/RPN). The help and advice of M. Valin and V. Lee have been very appreciated (AES/RPN). We are also grateful for the exceptional collaboration of the team of hydrological researchers of the University of Waterloo (F. Seglenieks, A. Graham); the efficient and excellent collaboration of the Water Survey of Canada with S. Saunders; and the advice of R. Hale and W. Brimley (Environment Canada, hydrology). Finally we would like to especially thank the B.C. Hydro Company (B. Chin and D. Cattanach) for the strong link created between hydrologists and atmospheric researchers.
