Figure 3


Fig. 3. The relation between Va and Vg-Va where {omega}-{gamma}=45° expressed in vectors. Circles represent constant Vg (15 m s-1) and a varying Vw (2,4,6 and 8 m s-1), + symbols represent constant Vw (6 m s-1) and varying Vg (2, 5, 8 and 11 m s-1). All the points shown here are subsets of those in Fig. 2B.
