Figure 4


Fig. 4. An illustration of the correlations that arise in random Vg and Vw data as a function of variance Vg/variance Vw and {omega}-{gamma}. (A) {omega}-{gamma}=45°, (B) {omega}-{gamma}=135°. In all cases, the variance of Vw =4 m2 s-2. In the top row, Vg does not vary. In the second row, variance of Vg =1 m2 s-2 and in the bottom row, variance of Vg =4 m2 s-2. Va is calculated on the basis of Vg, {gamma}, Vw and {omega}.
