In the paper Temporal and Spatial variation of the surface winds in the Gulf of California by Par¿s-Sierra et al. <2003> (Geophys. Res. Lett., 30(6), 1312, doi:10.1029/2004GL016716) it was reported that the monsoon character of the winds over the Gulf of California was not apparent in QuikScat data. Their result was based on the climatological winds derived from an objectively analyzed, gridded, and temporally interpolated data constructed by Tang and Liu <1996> from QuikScat data. A re-analysis of the original data does show monsoonal winds over the Gulf of California. Therefore, the previous data base is not suited for marginal or local seas.
