Objective identification of frontal wave cyclones
by T D Hewson

This brief paper further develops the objective front-plotting methodology described in Hewson (1996), to allow the tips of frontal wave cyclones to also be objectively identified.  The method embraces a new definition of frontal waves, but is analogous to operational practice in that these waves are located where cold and warm fronts join.  It is suggested that for the early stages of cyclonic development the new methodology will perform better than those previously published.
