Figure 8. Diurnal variation of mean wind speed (shaded, m s-1) and potential temperature (contoured, K), from November 2013–March 2014, in a vertical cross-section along the axis of propagation L (Fig. 5) at: (a) 0700 LST, (b) 1100 LST, (c) 1500 LST, (d) 1900 LST, (e) 2300 LST, (f) 0300 LST. The relative position of the C2 core is also shown. Potential temperatures are contoured in 0.5 K increments.
