No.  The westerly component of wind is the wind blowing from the west, this is the same as eastward (grid_x) wind.  The 'westerly', 'northerly' terminology is traditional meteorology, where as CF have adopted a vector component direction approach. 

Thus (grid)-westerly wind is x_wind (wind blowing xward) and (grid)-northerly wind is y_wind.
