Vertical cross-section of potential vorticity (PV, × 10⁻⁶ PVU, shaded), equivalent potential temperature (θₑ, K, green dashed contours), and potential temperature (θ, K, black solid contours) at (a) 20:00, (b) 21:00, (c) 22:00, and (d) 23:00 UTC. The cross-sections are oriented along wind directions of 75°, 110°, 80°, and 55° (wind rose) for each respective time. The vertical red line indicates the location of the nearest grid point to the study area. Horizontal axes show the latitude and longitude of the section. Wind barbs are plotted with half-barbs representing 2 m/s and full barbs representing 4 m/s.
