Error characterisation of atmospheric motion vectors

Since the operational use of locally generated atmospheric motion vectors (AMVs) by the Bureau of Meteorology began in 1992 (Le Marshall et al. 1992), it has been known that careful quality control of the winds is required to ensure a positive impact in regional and global data assimilation. Their ‘optimal’ use is particularly dependent on the characterisation of errors associated with particular vector types. Aust. Met. Mag. 53 (2004) 123-131
