Miscellaneous parameters in Figure 9 show 2D wind direction and speed. The acceleration spikes seem to be a result of ground contact. Vertical speed goes from - 600 to - 1200 fpm in the few seconds before touchdown while the 2D wind flops around. Alpha is not shown in the FDR report. It could be interesting.
See Flight in Low-Level Wind Shear, Frost 1983 for equations with 3D wind components.
